AB  - In order to contribute to palynological studies of cultivated plants in Serbia, micromorphological
features of pollen grains of Lactuca sativa L. (Asteraceae) were examined by both, light microscopy
(LM) and scanning electron microscopy (SEM). Morphological parameters, such as grain size and
shape, apertures and exine ornamentation were described. The morphometric data such as length of
polar axis (P), length of equatorial axis (E), P/E ratio, lacunae diameter, echinae size, and thickness
of exine excluding echinae were noted. Pollen grain were found to be isopolar, radially symmetrical,
medium-sized, oblate-spheroidal in shape (P/E = 0.94), sub-circular in equatorial view, and hexagonal
in polar view with straight sides in outline. The length of the polar axis (P) is 32.6 ± 3.7 μm and of the
equatorial diameter (E) 34.8 ± 2.7 μm. The pollen grain is 3-zonocolporate. Each compound aperture
consists of ectoaperture which is a meridionally elongated colpus with rounded ends, and pore-shaped
endoaperture. Exine ornamentation is echinolophate. Lophate (fenestrate) pollen grains, typical for
Asteraceae, are characterized by number of lacunae that appear as large window-like spaces, a depressed
area lacking ectexine. Each lacuna is surrounded by a system of echinate ridges. Lettuce pollen grains
have 15 lacunae, 3 poral, 6 abporal and 6 paraporal (polar regions are without lacunae, small, reduced
to triradiate ridge). The poral lacuna communicating with adjacent abporal lacunae via interlacunar
gaps is observed rounded in shape. Paraporal lacunae, lying in the mesocolpial region adjacent to one
side of an equatorial ridge, are pentagonal. Abporal lacunae are rounded or angular, broad towards the
pole. Average lacuna diameter is 10.8 ± 2.5 μm. Lophae (ridges) are with one row of echines that are
1.9 ± 0.3 μm long, pointed and some are curved. The еctexine thickness excluding echines, measured
under LM, averaged 5.7 ± 0.7 µm.

AB  - Испарљива једињења која емитују цветови, привлаче опрашиваче који
посредују у полном размножавању цветница. Viola odorata (Violaceae) је зељаста,
вишегодишња врста чије хазмогамне цветове карактерише специфичан јак мирис.
Круница се састоји од пет плавољубичастих листића. У основи бочних круничних
листића јавља се групацијa дугих белих трихома, док је преостала унутрашња
површина крунице глатка. Мирис цветова љубичице се обично приписује
епидермалним папилама присутним на горњим круничним листићима, док улога ових
трихома у емитовању мирисних једињења до сада није забележена. Истраживања су
обављена у циљу утврђивања микроморфолошких и анатомских особина бочних
круничних листића, док су хистохемијска анализа и Раманска спектроскопија
искоришћене за добијање брзе информације о хемијском саставу трихома, ради
процене њихове потенцијалне улоге у емисији мирисних супстанци. Анатомска
истраживања су обављена помоћу светлосног микроскопа. Трајни микросопски
препарати припремљени су према стандардној парафинској процедури. Хистохемијска
истраживања су урађена на свежем биљном материјалу. Крунични листићи су ручно
исечени, након чега су пресеци ткива третирани следећим реагенсима: Луголовим
раствором ради детекције скроба; бојом судан III ради детекције липида; боја толуидин
плаво (Toluidin blue) је коришћенa као полихроматска боја, a примењен је и
специфичан TIOFH протокол који се користи за детекцију осмофора. Према овом
протоколу прво се ради обезбојавање узорака етанолом и натријум хипохлоритом, а
потом следи бојење Луголовим раствором и бојама уљно црвено (Oil Red O) и
неутрално црвено (Neutral Red). Рамански спектри су снимљени коришћењем XploRA
спектрометра у спектралном опсегу од 200 до 3200 cm−1
. Раманско расејање је
побуђено ласером на таласној дужини од 532 nm. Трихоме присутне на унутрашњој
страни латералних круничних листића су у просеку дуге 671±170 µm, а широке 76±32
µm. Ове трихоме могу бити различите дужине али су истог цилиндричног облика, и
благо се сужавају према врховима. Њихова површина је прекривена кутикулом са
пругастом орнаментацијом. Хистохемијска реакција није показала присуство скробних
зрна, бојење липида је било слабо позитивно и обојила се само кутикула на површини
трихома, док је TIOFH бојење било изразито позитивно. Рамански спектар
појединачних трихома је показао да најдоминантнији пикови указују на присуство
глукозидних веза, као најважније компоненете једињења ћелијског зида. Пикови
уочени на 1515, 1147 и 996 cm−1 потичу од вибрација C=C, C–C веза, као и метил групе
(C–CH3) везане за коњуговане полиенске прстенове. Пикови средњег и нижег
интензитета на 1648, 1596, 1557, 1057 и 1021 cm−1 указују на присуство фенолних
једињења. Већина моноцикличних терпена показује снажну вибрацију деформације
прстена између 730 и 780 cm−1 и на око 1756 cm−1
. Резултати хистохемијске анализе и
Раманске спектроскопије указују на присуство супстанци које су обично повезане са
цветним мирисом, попут метил фенола. Ови резултати нису довољан доказ да се
утврди да ли су ове трихоме директно укључене у процес емитовања мириса, па би ову
претпоставку требало потврдити додатним хемијским анализама.

AB  - Spices plants are characterized by a rich and specific chemical composition and are widely used for
many purposes (as spices in cooking, in folk medicine, in aromatherapy, in the perfume industry). In
this work, Raman spectra recorded directly from individual anise (Pimpinella anisum L.), caraway
(Carum carvi L.), coriander (Coriandrum sativum L.), and fennel (Foeniculum vulgare L.) fruits
revealed some characteristic bands that can be assigned mainly to primary plant metabolites. The most
characteristic signals at 1688 and 1568 cm−1 are due to lignin, which is a major component of cell
walls in the hard pericarp. This band is related to the stretching of the aromatic rings of the phenolic
compounds that form the polymeric structure of lignin. The intense band near 1442 cm−1 can be assigned
as the CH2 shear deformation vibration of unsaturated FA. The degree of unsaturation of FA can be
estimated from the peak area of the bands at 1240 and 1312 cm−1, which are due to in-phase ═CH−
symmetric rocking and a methylene twisting vibration, respectively. In general, monocyclic monoterpenes
show intense Raman bands due to stretching vibrations of C═C bonds at about 1680 cm−1. In the case
of limonene, signal evident at 1680 cm−1 due to ν(cyclohexene C═C), while for carvone these bands
occur at 1670 and 1644 cm−1. Most monocyclic terpenes also show a strong ring deformation vibration
between 730 and 760 cm−1, and for limonene this band is at about 780 cm−1. The score plot of PCA
indicates two groups of objects along the PC1 axis: fennel, caraway and anise, coriander. The variables
responsible for the differentiation at 1579, 1461, 1104 and 667 cm-1 could indicate lignin, UFA and
monoterpenes, respectively. Raman spectroscopy showed as fast and useful tool for fast recognition
of fruits essential oil content in spices plants.

AB  - The pollen grains of Leiotulus aureus (syn. Malabaila aurea (Sm.) Boiss.) were examined by light and scanning electron microscopy in order to contribute to the taxonomical and melissopalynological studies of the species. Flower visitors have also been observed and analyzed aiming at the clarification of some pollination aspects including the species contribution to bee pasture.

AB  - Post-anthesis drought affects wheat production worldwide, primarily through the limitation of grain filling. The enhanced remobilization of stem reserves induced by drought can provide considerable carbon sources for grain filling. The aim of this study, which was part of an ongoing wheat-breeding program targeting drought tolerance, was to assess the ability of 20 contrasting common wheat genotypes (2 cultivars, 8 F6:7 families (FAM), and 10 parent genotypes (PAR) used to make the families) to remobilize stem dry matter under water-stressed conditions simulated via defoliation 10 days after anthesis, and to estimate the contribution of stem dry matter remobilization to grain weight. In two-year field trials, the genotypes were scored for agro-physiological and peduncle morpho-anatomical traits. Stem reserve contribution to grain weight per spike was significantly enhanced in defoliated plants but did not differ amongst the groups of genotypes. F6:7 families had higher grain-filling rate and 1000-grain weight but without improvement in grain weight per spike under defoliation compared with parental groups. The total area of chlorenchyma, phloem-area-related traits, and stem reserve contribution to grain weight were positively associated with grain weight per spike under defoliation, whilst in both treatments, the grain-filling rate was determined by stem height. These results imply that the grain-filling rate is a trait desirable for drought tolerance that can be improved during the breeding process. © 2023 by the authors.

AB  - The Balkan Peninsula is characterized by a great diversity of flora and vegetation. Moreover, it is native to
a large number of wild plant species containing carotenoids, biologically active compounds, beneficial for
human health. Carotenoid pigments exhibit a great antioxidant and anti-inflammatory effect, in addition to
beneficial impact on eye health, heart, blood vessels, cognitive function and antiaging. Nevertheless, their
role has been scientifically proven in prevention and treatment of cancer.
The aim of the research was to form a database on carotenoid plants of Serbia and the Balkans that is
set up electronically for easy access, management and updating. The research included the analysis and
organization of information on collected plants, as well as literature data related to the traditional use and
storage of plants and plant parts and products rich in carotenoids in fresh, dried or canned state.
Sixty wild plants from more than ten plant families were registered to contain these antioxidant pigments.
Among them three endemic species namely Lilium bosniacum (Beck) Fritsch (lily native to Bosnia and
Herzegovina), Ramonda nathaliae Pančić & Petrović and R. serbica Pančić were inscribed, of which the last
two are Tertiary relicts. The type and level of carotenoids varied depending on the plant species and organs
including leaves, petals, immature and ripe fruits, pulp, seeds, etc. According to database, fruits were the
richest source of these pigments. Reported carotenoid content, included both xanthophylls and carotenes,
whereas lutein and β-carotene were predominantly major compounds in berries and flowers respectively.
Total carotenoid content, determined by HPLC method, was the highest in fresh berries of Rubus fruticosus L.

AB  - The olive tree is one of the most important agricultural plants, affected by several pests and diseases that cause a severe decline in health status leading to crop losses. Olive leaf spot disease caused by the fungus Venturia oleaginea can result in complete tree defoliation and consequently lower yield. The aim of the study was to obtain new knowledge related to plant–pathogen interaction, reveal mechanisms of plant defense against the pathogen, and characterize fungal phyllosphere communities on infected and symptomless leaves that could contribute to the development of new plant breeding strategies and identification of novel biocontrol agents. The highly susceptible olive variety “Istrska Belica”' was selected for a detailed evaluation. Microscopy analyses led to the observation of raphides in the mesophyll and parenchyma cells of infected leaves and gave new insight into the complex V. oleaginea pathogenesis. Culturable and total phyllosphere mycobiota, obtained via metabarcoding approach, highlighted Didymella, Aureobasidium, Cladosporium, and Alternaria species as overlapping between infected and symptomless leaves. Only Venturia and Erythrobasidium in infected and Cladosporium in symptomless samples with higher abundance showed statistically significant differences. Based on the ecological role of identified taxa, it can be suggested that Cladosporium species might have potential antagonistic effects on V. oleaginea. © 2022, The Author(s), under exclusive licence to Springer Science+Business Media, LLC, part of Springer Nature.

AB  - Introduction: Potentilla indica (Jacks.) Th. Wolf commonly known as Indian Mock Strawberry or false strawberry, is
native to eastern and southern Asia (Himalayas, China, and Japan), but has been introduced worldwide and
commonly grown as ornamental. P. indica is very tolerant to different environmental conditions including high-altitude
habitat, areas with low/high temperatures, sun/ shade or drought.
Objectives: The aim of the research is to contribute to the ecophysiological study of the plant by analyzing the
anatomical characteristics that could be involved in response of plants to environmental stimuli and the adaptation to
abiotic stress.
Materials & methods: For light microscopy fixed plant material (petiole, leaf blade, stem, stolons, rhizome and
adventitious root) was dehydrated and embedded in paraffin. Sections were cut by sliding microtome and stained with
Alcian Blue-Safranin. Observation and photographs were done using a light microscope (Leica DM2000).
Results: Leaves are dorsiventral and amphistomatic (Fig 1a). Two types of trichomes are identified, non-glandular and
glandular present on both leaf surfaces. Non-glandular trichomes are unicellular, while glandular ones have uniseriate
stalk and globular head, usually made up of four cells each (Fig 1b). Palisade parenchyma is composed of two or
three layers of elongated cells while spongy parenchyma is composed of a few layers of cells with prominent
intercellular spaces.
In stolons subepidermal collenchyma is followed by one or two chlorenchyma layers and large cortical parenchyma
cells (Fig 1c). Pericycle is composed of continuous ring of sclerenchyma cells (Fig 1d). Vascular bundles are open
collateral, separated by parenchyma rays between.
Peridermis, cortical parenchyma and collateral vascular bundles are observed in the cross section of the rhizome and
pith parenchyma occupying the large area in the central part (Fig 2a, b, c).
In adventitious roots diarch, triarch, tetrarch or polyarch radial vascular bundles occur depending on the stage of
development (Fig 2d, e). Older roots have typically developed secondary xylem and phloem, and in external parts of
roots are visible rings of secondary meristem (Fig 2f).
Cubic crystals, probably of calcium oxalate, are randomly scattered predominantly in pith region of stem and in leaf
mesophyll.
Conclusion: Some of anatomical features of P. indica are quite common but it also has some specific performances,
especially in roots, what will be discussed. Considering the ability to withstand high-temperature and low-temperature
stress, additional physiological studies are also required.

AB  - Introduction: Pimpinella serbica (Vis.) Benth. & Hook., belonging to the Apiaceae, is native to the central and western
parts of Balkans (Bosnia and Herzegovina, Montenegro, North Macedonia, Serbia) and Albania. It prefers limestone
habitat at an average altitude of about 1300 m forming plant communities with other mountainous species, such as
spruce and Greek maple (Pancicii-Aceri heldreichii-Piceetum). In Serbia it inhabits mountains such as Kopaonik, Stara
planina, Zlatar, Javor, etc.
Objective: The pollen morphology of P. serbica, Balkan endemic species distributed in Serbia, were examined by
scanning electron microscopy (SEM) in order to contribute the morphological, taxonomic and melissopalynological
studies.
Materials & methods: The umbels were collected from wild plant populations at full flowering stage. A set of three
mounted and labelled voucher specimens were processed in standardized way and deposited in the herbarium
collection of the Faculty of Agriculture, University of Belgrade.
For SEM study the pollen grains were covered with gold (in BAL-TEC SCD 005 Sputter Coater, 100 seconds in 30
mA) and observed using JEOL JSM- 6390 LV electron microscope at an acceleration voltage of 20 kV. Pollen grains
were imaged in polar and equatorial view, and observations and measurements were done on a sample of 30 grains
for each morphological character. The following taxonomically significant features describing pollen grains were
examined: size, shape, exine sculpture, apertures, polarity, symmetry, equatorial (E) and polar (P) axes length, and
apocolpium index.
Results: The pollen grains of P. serbica are isopolar, radially symmetrical and small-sized (Figure 1a). The ratio
between the polar axis length (P = 21.5 ± 0.8 μm) and the equatorial diameter (E = 12.9 ± 0.9 μm) of 1.7 ± 0.2
indicates prolate shape (Figure 1b). The grains are slightly equatorially expanded with obtuse polar caps, and
triangular in polar view with interangular furrows (Fig 1c). The grains have tricolporate apertures with three straight
sunken ectocolpi arranged regularly meridionally, of mean length 17.7±0.9 μm, each one with endopore positioned in
the indentations between the mesocolpial lobes. Mesocolpial width is 7.3±1.8 μm. Apocolpium index amounts
0.39±0.04. The exine was found to have rugulate sculpture (Figure 1d).
Conclusion: Polen grains of P. serbica have typical form for Apiaceae family, but some fine details provided by the
current study could help in intrageneric differentiation contributing to taxonomic research. The analyzed
palynomorphological characteristics may be of special importance for estimating geographical origin of honey,
considering this species limited distribution area. The results revealed that exine ornamentation could be a diagnostic
trait taxonomically significant and useful for identification to species level

abstract = "Introduction: Pimpinella serbica (Vis.) Benth. & Hook., belonging to the Apiaceae, is native to the central and western
parts of Balkans (Bosnia and Herzegovina, Montenegro, North Macedonia, Serbia) and Albania. It prefers limestone
habitat at an average altitude of about 1300 m forming plant communities with other mountainous species, such as
spruce and Greek maple (Pancicii-Aceri heldreichii-Piceetum). In Serbia it inhabits mountains such as Kopaonik, Stara
planina, Zlatar, Javor, etc.
Objective: The pollen morphology of P. serbica, Balkan endemic species distributed in Serbia, were examined by
scanning electron microscopy (SEM) in order to contribute the morphological, taxonomic and melissopalynological
studies.
Materials & methods: The umbels were collected from wild plant populations at full flowering stage. A set of three
mounted and labelled voucher specimens were processed in standardized way and deposited in the herbarium
collection of the Faculty of Agriculture, University of Belgrade.
For SEM study the pollen grains were covered with gold (in BAL-TEC SCD 005 Sputter Coater, 100 seconds in 30
mA) and observed using JEOL JSM- 6390 LV electron microscope at an acceleration voltage of 20 kV. Pollen grains
were imaged in polar and equatorial view, and observations and measurements were done on a sample of 30 grains
for each morphological character. The following taxonomically significant features describing pollen grains were
examined: size, shape, exine sculpture, apertures, polarity, symmetry, equatorial (E) and polar (P) axes length, and
apocolpium index.
Results: The pollen grains of P. serbica are isopolar, radially symmetrical and small-sized (Figure 1a). The ratio
between the polar axis length (P = 21.5 ± 0.8 μm) and the equatorial diameter (E = 12.9 ± 0.9 μm) of 1.7 ± 0.2

AB  - Introduction: Raman spectroscopy, as a powerful diagnostic technique for molecular analysis of food samples, was
used as a rapid and reliable method for the discrimination of honey according to their source, as well as for faster
detection of honey counterfeits. Since honey contains different proportions of sugars as the dominant components, the
certain characteristic vibrational mode is useful to differentiate structural-based changes in these carbohydrates.
Objective: In order to contribute to a comprehensive database of Raman bands obtained from food samples, the
present study aimed to detect and confirm differences in chemical composition between homemade and commercial
honey using Raman spectroscopy as a fast tool combined with multivariate analysis (PCA).
Materials & methods: Raman scattering was excited by a laser at a wavelength of 532 nm equipped with 1200
lines/mm grating. The spectra preprocessing was realized using Spectragryph software, version 1.2.13. Principal
component analysis (PCA) was performed using PAST software. Multivariate analysis, based on PCA, was applied in
order to detect a possible difference in the chemical composition of honey samples.
Results: Raman spectra of honey show bands at 334, 420, 517, 624, 702, 816, 863, 915, 1070 and 1123 cm-1, which
can be attributed to the sugars expected to occur in honey (glucose, fructose and sucrose). Glucose and fructose
have dominant vibrational modes of C–C–C, C–C–O, C–O and C–C reported in the range of 200–500 cm-1. The
higher intensity band at ~417 cm-1 and its shoulder at 448 cm-1 are probably attributed to the C–C–O vibration of α-
and β- glucose, respectively. The glucose band at 417 cm-1 and band at 420 cm-1 of fructose band overlap, while 624
cm-1 is related to ring deformation of fructose. The band at 517 cm-1 could be assigned to the skeletal vibration of
glucose. The medium intensity bands in the range from 816 to 975 cm-1 are related to vibrations of glucose and
fructose. The band at 1123 cm-1 is assigned to the C-OH deformation of the glucose and sucrose, while a lower
intensity band at 1370 cm-1 is assigned to the CH and OH bending mode of sucrose.
The minor contribution of other carbohydrates, proteins, amino acids and organic acids were confirmed by Raman
spectroscopy by the bands at 334, 1077, 1266 cm-1 and 1460 cm-1.
The PCA analysis was performed using about forty Raman spectra. The score plot of PC1 versus PC2 shows a
reasonably good separation between the samples, where the first and second principal components described
86.21% of data variance. The score plot suggests the clear existence of separation between traditional and
commercial honey samples along PC1 axis. The loading plot shows that the variables with the highest positive
contribution along PC1 axis corresponded to the signals at 284, 392, 682, 795, 890, 1118 and 1198 cm-1, while
signals at 436 and 1026 cm-1 have the highest negative effects. Traditional honey comparing with commercial differs
in a higher amount in β-glucose and fructose (assigned to pyranoid ring) content.
Conclusion: This study confirmed that Raman spectroscopy can be applied for the determination of chemical
composition and combined with chemometric methods could confirm the differentiation of honey samples.
Spectroscopic methods, comparing with standard analytical tools, are especially suitable for this kind of evaluation
since they are fast, non-destructive and require a small amount of sample for analysis.

AB  - Monofloral sunflower honey was harvested from the enchanting vast sunflower fields in the
vicinity of Cestereg (Central Banat) serving as a rich source of floral nectar collected by honey
bees. The aim of the study was to detect predominant sugars such as glucose, fructose, sucrose
and maltose in sunflower honeyof known origin using Raman spectroscopy. The Raman spectra
were recorded with XploRA Raman spectrometer from Horiba JobinYvon, on laser at a wave
length of 785 nm. Several vibrational bands at 415, 514, 564, 622, 703, 769, 815 cm-1
, followed
by 856, 914, 964, 1021, 1067 and 1123, 1260, 1360 and 1455 cm-1
could be identified as
fingerprints of the major sugar constituents of honey, fructose and glucose, whereas sucrose and
maltose bands have been suppressed. The highest intensity bandat 415 and its shoulder at 446 cm1
are attributed to the C–C–O vibration of α- and β- glucose, respectively. The higher intensity
signals at 514cm-1
could be assigned to the skeletal vibration of glucose and 622 cm-1
to the ring
deformation of fructose, due to its highest content in the honey sample. Finally, the bands at
1123, 1260, 1360 and 1455 cm-1 were related to the C-O-H deformation of the glucose and
sucrose, C-O-C cyclic alkyl ethers of the fructose, CH and OH bending modes of the glucose and
sucrose and the symmetric deformation mode of CH2 in fructose, respectively. This study
confirmed that Raman spectroscopy can be applied for rapid determination of sugar contents of
commercial honey.

AB  - Pisum sativum var. saccharatum, варијетет познат као слатки грашак, за разлику од
сточног и обичног грашка, има јестиве махуне у чијим зидовима недостаје влакнасти
слој богат лигнином и које се у исхрани користе целе, незреле, сирове или благо
скуване.
Основне морфолошке карактеристике поленових зрна слатког грашка су анализирана
уз помоћ светлосног (LM) и скенирајућег електронског микроскопа (SEM), у циљу
доприноса палинолошким проучавањима гајених биљака Србије.
Анализом СЕМ микрографија, установљено је да су поленова зрна монадна,
изополарна и радијално симетрична, а с обзиром на величину, на граници између
класе средњих и великих. Дужина поларне осе (P) просечно износи 50,8±1,2 µm, а
екваторијалног пречника (Е) 22,5±1,8 µm. Однос (P/Е) у просеку износи 2,3±0,2
указујући на перпролатни облик. Екваторијално посматрано, зрна су скоро
правоугаоног облика, затупасто-конвексна на половима, док је њихов облик, поларно
посматрано, мање-више округласто-трорежњевит. Према броју, типу и положају
апертура, зрна су 3-зоноколпоратна. Апертуре типа ектоколпи (просечне дужине
38,3±2,0 µm) са уско-зашиљеним крајевима распоређене су меридионално, а такође су
јасно видљиве, често крупне, мање или више истакнуте ендопоре кружног облика.
Орнаментација егзине на мезокопијуму је ретикулатно-перфоратна, а на апоколпијуму
псилатна. Лумине ретикулума су полигоналне, округласте или неправилног облика,
различите величине, од 1,1 до 3,4 µm у пречнику, са танким мурима (0,71±0,12 µm).
Перфорације лумине су различите величине, округле или овалне, просечно 0,19±0,05
µm у пречнику. Ретко или густо зрнасти елементи присутни су на мембрани колпи.
Просечна дебљина егзине, снимане и мерене помоћу светлосног микроскопа износи
1,2±0,4 µm.

AB  - Истраживање је обухватило анализу морфологије полена сорте парадајза (Lycopersicon
esculentum Mill.) познате под називом „Воловско срце“, у циљу доприноса
палинолошкој збирци гајених биљака Србије. С обзиром на то да формира плод масе
500 g или више, ово је једна од најкрупнијих сорти парадајза која се у Србији гаји већ
дуги низ година. Парадајз је самооплодна биљка, али ради ефикаснијег оплођења и
плодоношења, цветови захтевају вибрационо опрашивање, тј. соникацију коју обављају
бумбари (Bombus sp.) или неке солитарне пчеле (Xylocopa sp.). Ови инсекти имају
способност да, приликом сакупљања флоралног нектара, вибрирају унутар цвета на
одређеној фреквенцији што изазива ослобађање поленовог праха из антера.
Поленова зрна су анализирана уз помоћ светлосног (SМ) и скенирајућег електронског
микроскопа (SЕМ). Истраживање је обухватило описивање и мерење основних
морфолошких карактеристика као што су: величина, облик, орнаментација,
апертурација, поларност, симетрија, дужина поларне и екваторијалне осе, дужина
колпи, ширина мезоколпијума и дебљина егзине.
Поленова зрна су монадна, у класи средње великих, изополарна и радијално
симетрична. У погледу апертурације су триколпоратна, са 3 узане меридионално
распоређене ектоколпе (просечне дужине 26,1±1,9 μm) и 3 слабо уочљиве ендопоре.
Мембрана колпе је гранулисана. Дужина поларне осе (P) износи 30,1±1,2 μm, а
екваторијалног дијаметра (Е) 15,9±1,1 μm. Однос ове две осе (P/Е) износи 1,9±0,1, што
указује на пролатни облик. Поларно посматрано, поленова зрна су округласта и
трорежњевита, а екваторијално посматрано су елиптична са зашиљеним половима.
Ширина мезоколпијума у екваторијалној зони просечно износи 11,0±0,3 μm.
Орманентација егзине је скабратна. Скулптурни елементи су неправилно распоређени,
са пречником у базалном делу мањим од 1 µm (0,12±0,03 µm), а њихов број по
јединици површине износи 12,1±1,2 по μm2
. Дебљина егзине, код екваторијално
постављених зрна посматраних светлосним микроскопом, измерена у средини
мезоколпијума, износи у просеку 0,9 ± 0,2 μm.

značaja mikromorfoloških karakteristika, naročito broja stoma, kao i anatomskih
karakteristika listova za prodiranje herbicida i posledične razlike u osetljivosti na
herbicide. Uzorci pšenice kao i sve tri korovske vrste sakupljeni su u maju 2020.
godine sa parcele pod usevom pšenice u selu Maovi (Šabac). Sve uzorkovane biljke
su bile sa potpuno formiranim cvastima tj. neposredno pre cvetanja. Za morfoanatomsku
analizu uzet je potpuno razvijen list koji se nalazi u čvoru ispod lista
zastavičara. Uzeto je ukupno po deset listova od svake vrste, a iz središnjeg dela
svakog lista uzet je uzorak veličine 2 cm i podeljen na dva dela. Jedna polovina
korišćena je za analizu anatomske građe, pri čemu su, nakon procedure kalupljenja u
parafin, sečenja i bojenja, dobijeni poprečni preseci sa kojih je merena debljina
epidermisa i debljina mezofila. Druga polovina korišćena je za mikromorfološka
ispitivanja tako što su lice i naličje lista tretirani providnim lakom za nokte, a otisci
površine su preneti na mikroskopske pločice pomoću lepljive trake. Na osnovu ovih
otisaka utvrđen je broj stoma po jedinici površine (gustina). Svi mikroskopski preparati
su analizirani pomoću mikroskopa Leica DM2000 i snimljeni kamerom Leica DFC320.
Merenja na digitalnim fotografijama su vršena u softverskom paketu Leica IM1000, a
zatim je urađena statistička analiza dobijenih vrednosti. Utvrđeno je da su listovi svih
ispitivanih vrsta amfistomatični. Najveći broj stoma na licu lista zabeležen je kod
pirevine i ljulja, dok je kod pšenice i divljeg ovsa gustina stoma bila dvostruko manja.
Na naličju lista pirevine, divljeg ovsa i pšenice broj stoma po jedinici površine lista je
bio sličan, dok je kod ljulja bio značajno manji. Budući da se brojnost stoma može
smatrati jednim od faktora koji mogu uticati na usvajanje herbicida, očekuje se da bi
razlike u gustini (broj po jedinici površine) stoma između ovih vrsta mogle uticati na
efikasnost usvajanja herbicida.

AB  - In this study, the vegetative anatomy of Artemisia umbelliformis subsp. eriantha, a Central European alpine glacial relict, wild-growing on Mt. Durmitor (Mon- tenegro) was examined for the first time. The aim was to investigate the general anatomy and particular anatomical traits which might have possible taxonomic value. Microscopic slides were prepared according to the standard histological procedures. The adventitious young root showed a primary structure, while the older root showed a secondary structure with a well-developed periderm on its surface. The rhizome showed a primary structure with elements of a secondary structure (periderm). The stem cross section is characterized by a round shape with a well-developed periderm at certain stages, and collateral vascular bundles ar- ranged in a circle. The petiole is concave in shape with a single-layered epidermis and parenchyma tissue with one large and two small vascular bundles. Druses and rhombohedral crystals are observed inside some petiole parenchyma cells. The leaf lobe cross section has an oblong-linear shape and is isolateral and amphistomatous in structure. The anticlinal walls of the leaf epidermal cells are sinuate. Secretory canals are present in the root cortex parenchyma (endodermal secretory canals) and the rhizome cortical parenchyma. The stem, petiole and leaf lack secretory canals. The stem and leaf are covered with T-shaped non-glandular and glandular trichomes. The taxonomic value of the analyzed characteristics is briefly discussed.

AB  - Anatomical analysis of root, rhizome, leaf, peduncle and inflorescences has been conducted on Balkan Amphoricarpos taxa, A. neumayerianus (Vis.) Greuter subsp. neumayerianus, A. neumayerianus subsp. murbeckii Bosnjak, A. autariatus Blecic & Mayer subsp. autariatus and A. autariatus subsp. bertisceus Blecic & Mayer using light microscopy (LM) and scanning electron microscopy (SEM), in order to examine the anatomical traits of this genus for the first time. All taxa show similar features. Young adventitious roots share a typical structure. Sclerenchyma fibers are present in the center of older root. On the rhizome cross sections, secondary tissues are noticed with wide parenchyma rays which interrupt a-well developed xylem. Rhizomes show eccentric growth. The leaf blade is amphistomatous, with dorsiventral structure. Crystal druses are found in leaf epidermal and mesophyll cells. The peduncle cross sections is characterized by more or less polygonal shape with medullary collateral vascular bundles arranged in a circle, and a few of them outside of the circle, toward to cortex region. Secretory canals are absent. Involucral bracts and paleae are characterised by the presence of multilayer sclerenchyma in the mesophyll. Inflorescence anatomy shows structures commonly described for Asteraceae members. Densely distributed vermiform (lanate) and glandular biseriate trichomes are present on the peduncle and on both leaf sides, but much more on the abaxial. Anatomical uniformity indicates very close relationships between examined taxa regarding conserve nature of the genome of the genus. Obtained characters contribute to the knowledge of the genus Amphoricarpos anatomy.

AB  - There are various opinions in the literature on the importance of morpho-anatomical leaf features, such as the number of stomata, the presence of trichomes, cuticle thickness, cell size, leaf thickness, etc. for the susceptibility of plants to foliar herbicides. Knowing that differences in the plant's sensitivity to herbicides may be due to differences in leaf sufrace and inner structure of leaves, a detailed micromorphological and anatomical analysis was performed on the leaves of tolerant and susceptible sunflower forms, both in cultivated hybrids and populations of weedy sunflower. It is interesting that while no significant differences in the number of trichomes and stomata between the resistant and susceptible weedy sunflower populations were observed, in comercial sunflower genotypes these numbers were significantly different. Namely, the number of stomata in the sensitive comercial sunflower hybrid was significantly higher than in the tolerant ones, but the tolerant hybrids had significantly more leaf trichomes than the sensitive one. Consequently, it is possible that the higher density of trichomes makes it impossible for the herbicides to reach the surface of the leaf epidermis, resulting in a reduced uptake. It has also been shown that plants with different levels of herbicide susceptibility also differ in various anatomical parameters.
AB  - U literaturi postoje oprečna mišljenja o značaju morfo-anatomskih parametara listova, kao što su broj stoma, prisustvo dlaka, debljina kutikule, debljina lista i sl. za osetljivost biljaka prema folijarnim herbicidima. S obzirom na to da razlike u osetljivosti hibrida/populacija prema herbicidima mogu da budu posledica razlika u površinskim strukturama i anatomskoj građi lista, u ovom radu je detaljno analizirana mikro-morfološka i anatomska građa listova tolerantnih i osetljivih formi suncokreta, kako gajenih hibrida tako i populacija hibridnih formi korovskog suncokreta (HFKS). Interesantno je da između rezistentnih i osetljivih populacija HFKS nije bilo statistički značajnih razlika u broju dlaka i stoma na listovima, ali kod hibridnih genotipova jeste. Naime, na naličju lista broj stoma kod osetljivog hibrida je bio statistički značajno veći nego kod tolerantnih, ali su tolerantni hibridi imali statistički značajno više dlaka na listovima od osetljivog, tako da je moguće da veća maljavost onemogućava dospevanje herbicida do površine epidermisa, što za posledicu ima njihovo manje usvajanje. Takođe je pokazano da se biljke različite osetljivosti prema herbicidima razlikuju i u različitim parametrima anatomske građe (debljina palisadnog i sunđerastog tkiva, debljina mezofila i debljina lista).

AB  - Comparative anatomical analysis of vegetative organs has been conducted on Artemisia campestris L., A. absinthium L., A. arborescens L., A. judaica L. and A. herba-alba Asso, using light microscopy, in order to examine the most important anatomical features and to find new valid taxonomic characters. Results have shown that general root, stem and leaf anatomical features and nonglandular and glandular trichomes are shared by all species. However, some characters (parenchyma sheath, which surrounded vascular bundle and extended to both epidermises, subepidermal collenchyma and the absence of secretory canals in the leaves) link together A. absinthium and A. arborescens from the same section. Some characters, as periderm and lignified pith parenchyma cells (A. campestris and A. arborescens), nonendodermal secretory canals in root cortex (A. absinthium and A. judaica) and secretory canals in the leaf phloem (A. judaica and A. herba-alba), connect species belonging to different sections. Moreover, some characters could be considered as species-specific, nonendodermal secretory canals in the root secondary phloem, triangular leaf shape on the cross section and secretory canals in the leaf parenchyma for A. campestris, secretory canals in the stem pith for A. absinthium, crystals in the pith parenchyma cells for A. arborescens and the absence of root secretory canals for A. herba-alba. Given results revealed qualitative characters, on the basis of which the studied species are anatomically distinguishable between each other, provide valuable features for better species identification and contribute to the anatomy of the genus Artemisia.

AB  - Comparative anatomical and micromorphological analyses of root, stem, peduncle, leaf and inflorescence have been conducted on two Xeranthemum species, X. annuum and X. cylindraceum, by light microscopy (LM) and scanning electron microscopy (SEM). The main goal of the study was to examine the most important anatomical features and to find new valid taxonomic delimiting characters for the first time in both species. Regarding vegetative organs anatomy, the data obtained in this study indicated that both species possessed secondary tissues in the root, although these plants are annual. Also, stem anatomy was a typical of the Compositae family members, and anomocytic stomata type and dorsiventral leaf structure were present. On the involucral bracts surface crystals were noticeable, while highly developed multilayer sclerenchyma was present in the mesophyll. Palea anatomy was very similar to bract anatomy. Some floral features were as follows: lateral anther dehiscence, corolla composed of uniseriate epidermis and with a homogeneous parenchyma in the mesophyll, inferior ovary and anatropous ovule with basal placentation. The specific quantitative characters that were different between the examined species were emphasized. Some selected, well defined qualitative anatomical characters (e.g. shape of the young stem and peduncle cross-sections, type of glandular trichomes and cortical vascular bundles occurrence), on the basis of which the studied species were distinguishable, strengthen the taxonomy of the Xeranthemum genus and provide features for better identification of the taxa. This is the first study of the anatomy of Xeranthemum species and some of the characters found (secondary growth and dorsiventral leaves) points towards an adaptation of mesophilous ancestors to xeric habitats in Xeranthemum.

AB  - In order to cope with all the natural phenomena and survive on different types of soil and in different climatic conditions, plants have perfected their means of propagation. Weed seeds are characterized by high diversity in all segments, both physical and chemical. Knowledge of the morphological characteristics of seeds and fruits of weed plants (mass, size, shape, colour, luster, odor, appearance of surface structures) is of great importance in the planning of weed control measures. The subject of this study were the seeds of the species Chenopodium album, C. hybridum, Anagallis arvensis, Veronica hederifolia and Amaranthus retroflexus, which were isolated during the weed seed bank assessment in the soil. After the physical extraction from the soil samples, the seeds were separated from the admixture, determined and then photographed with a stereomicroscope. The dimensions (length, width, seed thickness and length of the navel) were measured and any changes in the seed coat produced as a result of physical damage were monitored. The aim of this research was to expand the database, which should contribute to a more efficient determination of weed seeds. It was found that the seeds of the species studied in this paper were often broken and damaged, although in most cases with similar morphological features, as indicated by the literature data. The seeds of the species C. album were an exception, with dimensions significantly different from the data available in the literature. This occurrence can be explained by the diversity of seed anatomy in the Chenopodiaceae family and also by the fact that during their stay in the soil, permanent changes in the seed surface structures are possible.

AB  - BACKGROUND: . Wheat is widely affected by drought. Low excised-leaf water loss (ELWL) has frequently been associated with improved grain yield under drought. This study dissected the genetic control of ELWL in wheat, associated physiological, morphological and anatomical leaf traits, and compared these with yield QTLs. Methods. Ninety-four hexaploid wheat (Triticum aestivum L.) doubled haploids, mapped with over 700 markers, were tested for three years for ELWL from detached leaf 4 of glasshouse-grown plants. In one experiment, stomata per unit area and leaf thickness parameters from leaf cross-sections were measured. QTLs were identified using QTLCartographer. Results. ELWL was significantly negatively correlated with leaf length, width, area and thickness. Major QTLs for ELWL during 0-3 h and 3-6 h were coincident across trials on 3A, 3B, 4B, 5B, 5D, 6B, 7A, 7B, 7D and frequently coincident (inversely) with leaf size QTLs. Yield in other trials was sometimes associated with ELWL and leaf size phenotypically and genotypically, but more frequently under non-droughted than droughted conditions. QTL coincidence showed only ELWL to be associated with drought/control yield ratio. Discussion. Our results demonstrated that measures of ELWL and leaf size were equally effective predictors of yield, and both were more useful for selecting under favourable than stressed conditions.

AB  - Micromorphological and anatomical analyses of the indumentum of Nepeta rtanjensis, a Serbian/local endemic species, were performed by means of light and electron microscopy and described in detail. The leaves and stems bear numerous glandular trichomes, both peltate and capitate, as well as non-glandular unbranched trichomes. A basal epidermal cell, a short stalk cell and a large round head of four secretory cells constitute one peltate trichome. Capitate trichomes are short and long-stalked and can be divided into two types, based on the number of glandular head cells, and further into a few subtypes according to the length and number of cells in stalk. Capitate trichomes of smaller length with one-cellular or with a bicellular head have been previously reported in different Nepeta species; however, according to our best knowledge, no existing study has reported the presence of long capitate trichomes on vegetative organs in any other species of this genus.

AB  - Marshmallow (Althaea officinalis L.) root is used as a drug in medicine, pharmaceutical, cosmetic as well as in food products, due to the content of mucilage with a broad range of physicochemical properties. Since mucilage content in roots depends on genotype and growing conditions, the quality control is, therefore, one of the major tasks in the rational use of the drug. In this paper we compare data for mucilage content in roots obtained by standard procedure which implies measuring of swelling ratio in dried samples, with anatomical features of roots obtained by different methods for anatomical analysis, and we have shown that anatomical method could be used for determination of mucilage content in marshmallow root.

AB  - Drying kinetics and shrinkage of valerian plant root (Valeriana officinalis) was investigated during the convective hot air dryer with forced convection mode. Whole root without cutting, root cut into quarters, and root cut into 2 mm thin slices were used in drying experiments. Initial moisture content of roots was 51.2±0.3% and roots were considered to be dry when they lost 68% of the fresh weight and reached the moisture content of 10%. Drying air temperature was set to be 40 and 50°C, air velocity at 1 m/s. The relative humidity of drying air was not controlled and it depended on surroundings. The experimental results were fitted to the five thin layer drying models and according to the non-linear regression analysis Page model was most suitable to describe the drying kinetics. The characteristic drying curves were created for each experimental set and they showed that the samples' preparation strongly influenced the drying process and drying time. Experiments to determine shrinkage of different cell structures of valerian root were carried out for raw material, as well as for dried samples, by using optical and electron microscopy observations and measurements. It was observed that shrinkage processes are significantly dependent of the type of cell tissue and drying air temperature.
AB  - Istraživanje kinetike sušenja i analiza skupljanja biomaterijala korenja lekovitog bilja Valeriana officinalis izvršeno je na konvektivnoj sušari sa vrućim vazduhom kao agensom sušenja. U eksperimentima su korišćeni uzorci: ceo koren, koren sečen na četvrtine i koren sečen na uzorke debljine 2 mm. Početni sadržaj vlage u uzorcima iznosio je 51.2±0.3%, a uzorak se smatrao suvim onda kada sadržaj vlage opadne na 10%. Temperatura vazduha u sušari iznosila je 40 i 50oC, sa brzinom strujanja od 1 m/s. Relativna vlažnost vazduha koji dospeva na materijal nije kontrolisana i zavisila je od spoljnih uslova. Eksperimentalni rezultati su analizirani kroz pet najčešće korišćenih modela za opisivanje promene bezdimenzionog sadržaja vlage u vremenu kod sušenja u tankom sloju, pri čemu je ustanovljeno da se kinetika sušenja najbolje opisuje modelom Page-a. Postupcima optičke i elektronske mikroskopije izvršeno je posmatranje uzoraka svežeg i osušenog korenja pri različitim režimima sušenja u cilju praćenja skupljanja materijala. Ustanovljeno je da proces skupljanja bitno zavisi od vrste ćelijskog tkiva u posmatranom poprečnom preseku materijala i od temperaturnog režima sušenja.

The characteristic drying curves were created for each experimental set and they showed that the samples' preparation strongly influenced the drying process and drying time. Experiments to determine shrinkage of different cell structures of valerian root were carried out for raw material, as well as for dried samples, by using optical and electron microscopy observations and measurements. It was observed that shrinkage processes are significantly dependent of the type of cell tissue and drying air temperature., Istraživanje kinetike sušenja i analiza skupljanja biomaterijala korenja lekovitog bilja Valeriana officinalis izvršeno je na konvektivnoj sušari sa vrućim vazduhom kao agensom sušenja. U eksperimentima su korišćeni uzorci: ceo koren, koren sečen na četvrtine i koren sečen na uzorke debljine 2 mm. Početni sadržaj vlage u uzorcima iznosio je 51.2±0.3%, a uzorak se smatrao suvim onda kada sadržaj vlage opadne na 10%. Temperatura vazduha u sušari iznosila je 40 i 50oC, sa brzinom strujanja od 1 m/s. Relativna vlažnost vazduha koji dospeva na materijal nije kontrolisana i zavisila je od spoljnih uslova. Eksperimentalni rezultati su analizirani kroz pet najčešće korišćenih modela za opisivanje promene bezdimenzionog sadržaja vlage u vremenu kod sušenja u tankom sloju, pri čemu je ustanovljeno da se kinetika sušenja najbolje opisuje modelom Page-a. Postupcima optičke i elektronske mikroskopije izvršeno je posmatranje uzoraka svežeg i osušenog korenja pri različitim režimima sušenja u cilju praćenja skupljanja materijala. Ustanovljeno je da proces skupljanja bitno zavisi od vrste ćelijskog tkiva u posmatranom poprečnom preseku materijala i od temperaturnog režima sušenja.",
