AB  - Jabuka je jedna od najgajenijih vrsta voćaka u svetu i u Srbiji. Kvalitet plodova
jabuke je značajan kako za stonu potrošnju, tako i za prerađivačku industriju.
Tradicionalni genotipovi, lokalne populacije i divlji srodnici kultivisanih biljaka pokazuju
širok spektar raznovrsnih osobina kvaliteta i otpornosti na stres, što može biti značajno
za budućnost poljoprivrede. Oni predstavljaju važan resurs za buduće programe
oplemenjivanja i imaju veliki značaj u kontekstu rastućih klimatskih promena.
Konzervacija i održiva upotreba tradicionalnih genotipova obezbeđuje diverzitet ishrane
lokalnih zajednica i veću nezavisnost lokalnih sistema proizvodnje hrane. Tradicionalni
genotipovi gajeni u tradicionalnim, ekstenzivnim poljoprivrednim sistemima su takođe
značajni sa aspekta zaštite životne sredine u poljoprivredi. Oni takođe imaju kulturološki
i gastronomski značaj.
Region zapadne Srbije je veoma bogat tradicionalnim genotipovima voća, pa stoga
predstavlja zanimljivo područje za istraživanje ovih genetičkih resursa. Cilj ovog rada je
bila evaluacija kvaliteta i senzoričkih osobina plodova 11 tradicionalnih genotipova
jabuke iz zapadne Srbije, koja je praćena analizom saznanja vezanih za upotrebu ovih
genotipova. Sa aspekta kvaliteta plodova, mereni su masa, širina i dužina ploda, čvrstina
ploda, sadržaj solubilnih materija i organskih kiselina. Senzoričke osobine plodova su
ocenjene putem upitnika za najvažnije karakteristike ploda: izgled, miris, ukus, sočnost i
trpkost.
Analiza morfoloških osobina je pokazala da je najveću masu plodova, ali i
najmanju čvrstinu imao genotip 'Kožara žuta'. Najčvršći plodovi su bili prisutni kod
genotipova 'Repača' i 'Kožara starinska'. Najveći sadržaj solubilnih materija i organskih
kiselina su imali plodovi genotipa 'Kožara starinska'. Najniži sadržaj organskih kiselina
109
odlikuje genotipove 'Valijka', 'Bela vajlija' i 'Šarenika', dok je najniži sadržaj solubilnih
materija prisutan kod genotipova 'Streknja' i 'Bela valija'.
Evaluacijom kvalitativnih i senzornih osobina najviše ocene za izgled je imao
genotip 'Zvečarka' zbog veoma atraktivnih plodova, ali i najnižu ocenu ukusa. Plodovi
jabuka 'Repača' i 'Kožara starinska' su bili najsočniji, ali su bili i najmanje atraktivni za
potrošače. Najbolji ukus, praćen dobrom aromom, su imali plodovi genotipova
'Lepocvetka' i 'Valijka'.
Na osnovu tradicionalnih saznanja, genotip 'Kolačara' je najbolje poznat lokalnoj
zajednici i ima prepoznat potencijal kao jabuka za preradu, dok je potencijal genotipova
'Budimka' i 'Streknja' prepoznat u proizvodnji sokova. Među ispitivanim genotipovima
zbog svojih kvalitativnih osobina 'Lepocvetka' je pokazala veliki potencijal za stonu
potrošnju, iako nije široko poznata. Najmanje poznat lokalnoj zajednici je genotip
'Repača', ali zbog izuzetnih ocena ukusa, arome i sočnosti može biti zanimljiv za stonu
potrošnju. Takođe ovaj genotip ima izuzetno čvrste plodove, što ukazuje na njegov
potencijal u održanju kvaliteta tokom skladištenja.

AB  - The effect of three different temperatures (8, 16 and 24°C) on pollen germination and pollen tube growth in vitro in eight quince cultivars (‘Leskovacka’, Vranjska’, ‘Morava’, ‘Pazardzijska’, ‘Hemus’, ‘Asenica’, ‘Portugal’ and ‘Triumph’) was studied. The research was carried out in a two-year period (2015-2016). Germination rate and pollen tube growth were determined on the culture medium containing 15% sucrose and 0.7% agar. The temperature showed a significant effect on in vitro pollen germination and pollen tube length. The lowest pollen germination was determined at the temperature of 8°C (22.73%). However, pollen germination was three times higher at temperatures of 16 and 24°C (62.60 and 72.16%, respectively). The temperature effect was significantly more pronounced on the pollen tube length. The smallest pollen tube length was determined at 8°C (241.5 μm) and it was four to five times lower than the pollen tube length measured at 16 and 24°C (809.6 and 1137.4 μm, respectively). On this basis, it can be concluded that the temperature of 8°C was not sufficient for pollen germination and pollen tube growth in quince cultivars. However, temperatures of 16 and 24°C were optimal for pollen germination and pollen tube growth.

AB  - This paper presents the results of the two-year (2015-2016) research of changes in fruit quality of quince fruits during cold storage. The investigations were conducted in eight quince cultivars: ‘Vranjska’, ‘Leskovacka’, ‘Morava’, ‘Pazardzijska’, ‘Hemus’, ‘Asenica’, ‘Portugal’ and ‘Triumph’. The fruits of the quince were kept in cold storage with normal atmosphere for five months, from October 20 to March 20, in temperature 0-2°C and air humidity 80%. After this period, changes in fruit quality were determined. The highest fruit weight loss was found in the cultivar ‘Pazardzijska’ (16.33%), and the lowest in ‘Asenica’ and ‘Morava’ (6.66 and 7.98%, respectively). Also, in ‘Pazardzijska’, the biggest soluble solids content (SSC) decrease (14.70%) was determined, while the smallest SSC decrease was determined in ‘Leskovacka’, ‘Morava’ and ‘Portugal’ (below 4%). The total acid content decrease varied from 33.05% in ‘Leskovacka’ to 63.75% in ‘Pazardzijska’. The losses in fruit firmness were smallest in ‘Pazardzijska’, and the largest in ‘Portugal’. The occurrence of flesh browning was lowest in ‘Asenica’ and ‘Hemus’, and largest in ‘Pazardzijska’. Of the investigated quince cultivars, the best results during the cold storage were determined in ‘Leskovacka’, ‘Morava’ and ‘Asenica’, and the worst in ‘Pazardzijska’.

AB  - Effect of irrigation on fruit quality and yield of Red Cap apple variety depending on crop load were studied. The aim of the paper is to determine how many apple fruits can be left on trees in third vegetation, growth under different irrigation treatments (without irrigation, normal irrigation - control and increased irrigation - double irrigation rate). For the Red Cap variety in the third year after planting, in order to achieve good fruit quality and satisfactory yield, it is necessary to leave a maximum of 25 fruits per tree, or 3.5 fruits per cm2of trunk cross-sectional area (TCSA). Different irrigation treatments have influence on the fruit size, the proportion of first class fruits, as well as the degree of ripeness of the fruits. Increased irrigation during the months of July and August affects these parameters, but to a lesser extent than the crop load. The largest irrigation effect on the increase of fruit size had trees from crop load III, who had 5,5 fruits per cm2 of TCSA. Increased irrigation during July and August had no statistically significant effect on tested parameters on trees that had less than 4,5 fruits per cm2 of TCSA and trees that had more than 6,5 fruits per cm2 of TCSA.

AB  - Aim of study: To determine the self-compatibility level of eight quince cultivars. Area of study: The region of Belgrade (Central Serbia). Material and methods: Pollen tube growth in vivo and fruit set in two pollination variants (self- and open-pollination) were studied in eight quince cultivars. The quantitative parameters of pollen tube growth (average number of pollen tubes in the upper and middle third of the style, base of the style and in the ovary; the dynamics of pollen tube growth through these parts of the pistil) was determined using the fluorescence microscopy. Main results: The parameters of pollen tube growth and fruit set were primarily dependent on the genotype and variants of pollination. All studied parameters were significantly higher in the open-pollination variant compared with the self-pollination in all cultivars. In the self-pollination variant, 'Leskovacka' and Vranjska' had the highest number of pollen tubes that penetrated the ovary (2.10 and 0.54 in average, respectively), as well as the largest percentage of pistils with the penetration of pollen tubes in the nucellus of ovules six days after pollination (40.09% and 14.74%). Also, they had the highest percentage of initial fruit set (17.01% and 28.52%) and final fruit set (9.32% and 9.86%). Based on this, 'Leskovacka' and 'Vranjska' can be classified as self-compatible cultivars, while the others are self-incompatible. Research highlights: The majority of quince cultivars were self-incompatible. When establishing new orchards with these cultivars, care should be taken about the choice of pollenisers in order to achieve high yields.

When establishing new orchards with these cultivars, care should be taken about the choice of pollenisers in order to achieve high yields.",

AB  - Morphology and ultrastructure of pollen grains were studied in 13 Oblacinska sour cherry clones in three years using scanning electron microscopy (SEM). All studied clones had isopolar, radially symmetric and tricolpate pollen grains. Length and width of pollen grains varied in a range of 50.03-55.97 mu m and 25.16-28.37 mu m respectively. Pollen shape in all the studied clones was identified as prolate. The smallest colpus length was found in the clone 8 (43.73 mu m), and the highest in the clone 3 (49.16 mu m). The highest colpus and mesocolpium width had the clone 3 (1.73 mu m; 14.87 mu m) and the lowest had the clone 7 (1.46 mu m; 13.78 mu m). All studied clones had striate exine ornamentation. Number of ridges per 100 mu m(2) of the exine surface was the highest in the clone 11 (16.7) and lowest in the clone 2 (14.1). Ridge and furrow width ranged from 0.46 to 0.61 mu m and from 0.45 to 0.59 mu m, respectively. The clones have been classified into three clusters based on all studied properties. Pollen grains examination by SEM indicated that several morphological parameters (pollen size and exine characteristics) can be used to distinguish Oblacinska sour cherry clones.

AB  - In 13 clones of ‘Oblačinska’ sour cherry, during the three-year period of investigation, the characteristics of the tree (trunk circumference, trunk height, tree height, crown height, crown diameter) and the shoot (shoot diameter, shoot length, internode length) were studied. Significant differences between the studied clones and years of testing were determined for all investigated traits. Interaction clone × year showed significant differences only for the shoot characteristics. The lowest tree vigour was found in clone 13, and the highest in clones 3 and 6. Clone 3 also had the highest shoot length and internode length. The lowest shoot length was observed in clone 12, and internode length in clone 9. The coefficients of variation and heritability were significantly higher for the tree characteristics than for the shoot characteristics. The lowest coefficient of variation was determined for the shoot diameter (3.12%), and the highest for the trunk circumference (22.03%). The coefficient of heritability ranged from 24.32% for the internode length up to 98.37% for the trunk circumference. The high values of the coefficients of heritability obtained mainly for the tree characteristics indicate the low impact of environmental factors on their manifestation. The obtained results can be of importance for the selection of the best clones of ‘Oblačinska’ sour cherry.

AB  - Fruit set and yield potential were studied in 15 genotypes of vineyard peach of late maturity (from middle to the end of September) during a three-year period (2012-2014). The study was carried out at the Experimental Station Radmilovac of the Faculty of Agriculture in Belgrade. Genotypes were evaluated for: Initial and final fruit set, fruit weight, number of fruits m-1 of shoot length and yield m-1 of shoot length. Initial fruit set varied from 36.0% (genotype IV/16) to 67.0% (genotype IV/14), and final fruit set from 24.9% (genotype IV/13) to 51.2% (genotype IV/14). Fruit weight ranged from 40.1 g (genotype II/24) to 78.2 g (genotype II/17). Highest number of fruits m-1 of shoot length was recorded at genotype II/17 (21.3) and the lowest at genotype II/31 (9.6). Yield m-1 of shoot length varied from 0.5 kg (genotypes II/13 and II/24) to 1.4 kg (genotype IV/18). Among studied vineyard peach genotypes, three genotypes (II/17, IV/17 and IV/18) can be recommended as promising related to yield potential, or as starting material for new peach cultivars of late maturity in further breeding work.

AB  - Phenological traits, yield, and fruit characteristics of 14 plum cultivars of late maturation period were studied in the region of Belgrade in the five-year period (2013-2017). The control cultivar for comparison was 'Stanley'. The average time of flowering was in the first half of April, and of fruit maturation in the second half of August and the beginning of September. Yield per tree was lowest in the cultivar 'Pozna Plava' (10.2 kg) and highest in the cultivar 'Topking' (23.6 kg). Compared to the control, significantly lower yield was achieved in three cultivars: 'Pozna Plava', 'Vengerka Pozdnyaya', and Narach'. Fruit weight ranged from 26.1 g in the cultivar 'Elena' to 57.0 g in the cultivar 'Empress'. Compared to the control, it was significantly higher in three cultivars (Empress', `Vengerka Pozdnyaya', and 'Tophie'). All studied cultivars had high soluble solids content, ranging from 17.1% to 21.6%. The best rated cultivar for fruit appearance was 'Empress', while cultivars 'Nada' and 'Pozna Plava' were best scored for taste.

AB  - This paper presents the results of two years of research experiments (2011-2012) for flowering phenology (start, full and end) and yield potential (initial and final fruit set, fruit weight and yield m-1 of shoot length) of eight promising peach hybrids obtained from crossing combination ‘Flaminia’ × ‘Hale Tardiva Spadoni’. The flowering of studied hybrids occurred from the end of March to mid-April and lasted from 10.0 to 14.0 days. Hybrids FH1, FH4 and FH6 dispayed the earliest and hybrid FH5 had the latest start of flowering. The tested hybrids were statistically significantly different in terms of initial and final fruit set and fruit weight. Initial fruit set was very high and ranged from 69.3% in the hybrid FH3 to 97.9% in the hybrid FH7. The hybrid FH7 had the largest final fruit set (52.7%), while the hybrid FH1 had the lowest final fruit set (24.0%). Fruit weight ranged from 97.7 g (hybrid FH6) to 165.6 g (hybrid FH3). The highest yield m-1 of shoot length was obtained in hybrids FH3 (2.7 kg) and FH7 (2.6 kg) and lowest in hybrids FH5 and FH8 (1.8 kg). Hybrids FH3 and FH7 can be singled out as potentially the most cropping, which makes them interesting for growing in areas where there is a risk of frost. Also, they can be important in breeding programs when creating new peach cultivars of high yield potential.

AB  - The focus of our research was to evaluate different apples cultivars in terms of their biological properties and bioactive compounds content, and determine the levels of their resistance (or susceptibility) to fire blight. The properties of 10 scab-resistant apple cultivars were examined on the Zica monastery estate (West Serbia) during the period from 2011 to 2015. The biological and chemical properties such as firmness, maturity stage, total soluble solids, total acids, total and reducing sugars, ascorbic acid content and surface blush of apple fruits were monitored. Various phenolic compounds in the tested samples were tentatively identified by LC-MS analyses. A study of generative properties included: number of flowerbuds, fruit mass and width, crop load, yield efficiency and yield. During the period of blooming and intensive shoot growth, artificial inoculations were carried out. For each cultivar, a fire blight score was determined by dividing the average length of necrotic tissue by the average total shoot length. In the study period, the cultivars 'CroldRush' (41.1 t ha(-1)) and 'Florina' (35.9 t ha(-1)) produced the highest yields, and the cultivars 'Discovery' (19.0 t ha(-1)) and Selection 25/63 (15.1 t ha(-1)) the lowest. The cultivar 'William's Pride' produced the largest fruits, with an average fruit mass of 206.8 g. The earliest harvest period was recorded for the cultivar 'Discovery' (end of July), and the latest for the cultivar 'CroldRush' (beginning of October). The cultivar 'Enterprise' had the highest value of total phenols (432.2 mg 100 g(-1) FW), while the cultivar 'Topaz' had the highest value of total flavanols (145.2 mg 100 g(-1) FW). The highest degree of susceptibility to fire blight was found in Selection 25/63, and the greatest resistance was manifested by the cultivar 'CroldRush'. In the five-year study period, the cultivars 'GoldRush', 'Rewena' and 'Enterprise' exhibited better bio-chemical properties and higher levels of resistance to fire blight than the remaining cultivars.

During the period of blooming and intensive shoot growth, artificial inoculations were carried out. For each cultivar, a fire blight score was determined by dividing the average length of necrotic tissue by the average total shoot length. In the study period, the cultivars 'CroldRush' (41.1 t ha(-1)) and 'Florina' (35.9 t ha(-1)) produced the highest yields, and the cultivars 'Discovery' (19.0 t ha(-1)) and Selection 25/63 (15.1 t ha(-1)) the lowest. The cultivar 'William's Pride' produced the largest fruits, with an average fruit mass of 206.8 g. The earliest harvest period was recorded for the cultivar 'Discovery' (end of July), and the latest for the cultivar 'CroldRush' (beginning of October). The cultivar 'Enterprise' had the highest value of total phenols (432.2 mg 100 g(-1) FW), while the cultivar 'Topaz' had the highest value of total flavanols (145.2 mg 100 g(-1) FW). The highest degree of susceptibility to fire blight was found in Selection 25/63, and the greatest resistance was manifested by the cultivar 'CroldRush'. In the five-year study period, the cultivars 'GoldRush', 'Rewena' and 'Enterprise' exhibited better bio-chemical properties and higher levels of resistance to fire blight than the remaining cultivars.",

AB  - The evaluation of 15 diploid plum cultivars (mostly Prunus cerasifera hybrids) originating from Russia, Belarus, Ukraine, and Bulgaria was carried out in the region of Belgrade over a period of four years (2011-2014). The time of flowering of studied cultivars was early, at the end of March and the first decade of April. Most cultivars are characterized by the early time of maturation (the last week of June or the first week of July). With the exception of the ‘Crvena Afska’, all other cultivars had high productivity (scores 4.0-4.8 on a 0-5 scale). Fruit weight ranged from 18.9 g in ‘Kolonovidnaja’ to 40.3 g in ‘Sonejka’. Stones were relatively small (0.74-1.47 g), and their share in the total fruit weight was 2.2-5.1%. The content of soluble solids ranged from 10.5-19.5%, while the content of titratable acids varied from 0.84-2.17%. Most of the studied cultivars are suitable for fruit processing, especially ‘Krimska Zholtaya’, ‘Soneyka’, and ‘Mara’. Some cultivars, such as ‘Dezertnaya’, ‘Obilnaya’, ‘Lama’, and ‘Naidyona’ can also be used for fresh consumption.

AB  - Pollen viability of eight quince cultivars (ʻLeskovackaʼ, ʻVranjskaʼ, ʻMoravaʼ, ʻPazardzijskaʼ, ʻHemusʼ,
ʻAsenicaʼ, ʻPortugalʼ and ʻTriumphʼ), was studied in the two-year period (2011-2012). Testing of
pollen viability was performed using two methods: the staining of pollen with acetocarmine (indirect
method) and pollen germination in vitro with sucrose and agar-agar (direct method). Studied
cultivars differed significantly in terms of pollen viability. The lowest percentage of stained pollen
grains was detected in ʻLeskovackaʼ cultivar (70.29%) and the highest in the cultivars ʻAsenicaʼ,
ʻHemusʼ and ʻTriumphʼ (over 90%). Similarly to that, the lowest percentage of pollen germination
was obtained in ʻLeskovackaʼ cultivar (62.86%) and the highest in the cultivars ʻMoravaʼ, ʻAsenicaʼ,
and ʻTriumphʼ (over 80%). With the exception of ʻPortugalʼ cultivar, the values of pollen viability
determined by staining with acetocarmine were higher for 3-15% compared to the pollen
germination in vitro. However, values obtained using these tho methods are highly positively
correlated. On the basis of obtained results, the both methods can be recommended as reliable tests
for pollen viability of quince, although priority should be given to the method of pollen germination
in vitro, because it is more accurate. All tested cultivars are distinguished for high pollen viability,
and can be successfully used as male parents in hybridization. In addition, they also can be
recommended as a good pollenisers when are planting new quince orchards.

AB  - The suitability of five apricot cultivars: ‘Aurora’, ‘Laycot’, ‘Pinkcot’, ‘Sylred’ and ‘Veecot’ as pollenizers for ‘Goldrich’ were studied. The study included the phenology of flowering, pollen germination, fruit set and growth of pollen tubes in vivo in the pistil. Pollen germination was determined on the medium with agar and 15% sucrose. The growth of pollen tubes in the pistil was determined by fluorescence microscopy, and fixation of pistils was done in three terms (2, 4 and 6 days after pollination). Regarding the flowering time, all tested cultivars overlapped well with ‘Goldrich’. Besides, all tested cultivars had good pollen germination, ranging from 58 to 74%. The highest fruit set was obtained in combinations with ‘Veecot’ (34%) and ‘Sylred’ (30%). Significantly lower fruit set was obtained in combinations with ‘Laycot’ (17%) and ‘Pinkcot’ (15%), while the combination with ‘Aurora’ gave the lowest fruit set (4%). First pollen tubes at the base of the style were observed on the second day after pollination, but their number increased significantly on the fourth day after pollination. Later, on the sixth day after pollination, the number of pollen tubes was not significantly increased. Number of pollen tubes at the base of the style and in the ovary was significantly higher in variants with ‘Veecot’, ‘Sylred’, ‘Pinkcot’ and ‘Laycot’, comparing to the variant with ‘Aurora’. Based on these results, ‘Veecot’ and ‘Sylred’ can be recommended as the best pollenizers for ‘Goldrich’. Satisfactory results were given by ‘Pinkcot’ and ‘Laycot’, while ‘Aurora’ proved to be a bad pollenizer.

AB  - Fluorescence microscopy is a relatively rapid and reliable method to determine self-incompatibility in fruit-tree species. It is based on observation of pollen-tube growth in the pistils. Pollen tubes stained with fluorochromes show fluorescence when exposed to ultraviolet light. Testing of the self-compatibility trait was carried out in 123 apricot cultivars using fluorescence microscopy. In self-compatible cultivars, in the majority of pistils (60-100%), the pollen tubes reached the ovary. In contrast, in self-incompatible cultivars, pollen tubes growth ceased in the style, with plugs forming at their tips. In these cultivars, pollen tubes rarely (0-30%) reached the base of the style. Although apricot cultivars of the European eco-geographical group are traditionally considered self-compatible, we identified many self-incompatible cultivars, especially among those originating from new North American and West European breeding programs. About half ( 62) of the studied cultivars were self-incompatible. Given that self-incompatibility occurs frequently among new apricot cultivars, special care should be taken when considering cultivar composition in new orchard plantings.

AB  - Seventy-five vineyard peach [Priam persica (LJ Batsch] accessions, obtained by seed propagation and originating from different regions of Serbia, were characterized using a set of 39 agro-morphological traits. The evaluation was carried out over a 3-year period in a vineyard peach collection situated at the Radmilovac Experimental Station, owned by the Faculty of Agriculture, Belgrade University. To investigate diversity, descriptive statistics and multivariate analyses were used. Most studied traits showed high variability. The variability of descriptive traits was highly pronounced for fruit ground and flesh colour; regarding metric traits, the highest variation was recorded for trunk circumference, petal width, flower density, fruit set, fruit weight, sweetness index, fruit taste and fruit flavour. According to PCA, traits with high discriminating power were those related to flower type, colour and size, fruit size and presence of over colour, tree height, ripening time and fruit taste. The cluster analysis grouped accessions into three main clusters and a few sub-clusters. Agronomically important traits allowed a clear separation between the clusters, while morphological traits had almost no impact on this. This study provided information that is important for assessing the biodiversity of vineyard peach accessions, to develop guidelines useful for the description, classification and conservation of valuable local germplasm. Moreover, the phenotypic variability in the vineyard peach collection was found to be very high, suggesting there is extensive genetic diversity available for peach cultivar and rootstock breeding programs.

AB  - This paper presents the results of a three-year research (2010-2012) of unusual growth of pollen tubes in the ovary in eight cultivars of quince in two pollination variants (self-pollination and open-pollination). Unusual behavior of pollen tubes growth could be seen in all parts of the ovary, and it was most often manifested by larger or smaller branching and the formation of bundle in the ovary, without signs of further penetration of pollen tubes to the ovule. In addition, in a small number of cases, branching of the pollen tubes, as well as bypassing micropyle and forming swellings at the tips of the pollen tube was noticed. There were also the cases where the pollen tube filled embryo sac forming a bundle in it. The occurrence of unusual growth of pollen tubes in the quince ovary was primarily dependent on the genotype and pollination type. This phenomenon was more expressed in open-pollination than in self-pollination variant in all examined cultivars. Leskovacka cultivar was characterized by the highest percentage of unusual growth of pollen tubes in both variants of pollination, as follows: 13.23% (self-pollination) and 15.89% (open-pollination).

abstract = "This paper presents the results of a three-year research (2010-2012) of unusual growth of pollen tubes in the ovary in eight cultivars of quince in two pollination variants (self-pollination and open-pollination). Unusual behavior of pollen tubes growth could be seen in all parts of the ovary, and it was most often manifested by larger or smaller branching and the formation of bundle in the ovary, without signs of further penetration of pollen tubes to the ovule. In addition, in a small number of cases, branching of the pollen tubes, as well as bypassing micropyle and forming swellings at the tips of the pollen tube was noticed. There were also the cases where the pollen tube filled embryo sac forming a bundle in it. The occurrence of unusual growth of pollen tubes in the quince ovary was primarily dependent on the genotype and pollination type. This phenomenon was more expressed in open-pollination than in self-pollination variant in all examined cultivars. Leskovacka cultivar was characterized by the highest percentage of unusual growth of pollen tubes in both variants of pollination, as follows: 13.23% (self-pollination) and 15.89% (open-pollination).",

AB  - The characteristics of growth and yield of seven quince cultivars: 'Vranjska', 'Morava', 'Pazardzijska', 'Hemus', 'Asenica', 'Portugal' and 'Triumph' were studied in the Belgrade region during the four-year period (2010-2013) in comparison with the cultivar 'Leskovacka', which was used as the standard. The tested cultivars were significantly different in terms of vigour and productivity. The lowest vigour was shown by 'Leskovacka' cultivar and the highest by 'Portugal' and 'Morava'. The highest yield tree(-1) and unit area(-1) was found in 'Triumph' and 'Portugal', and the lowest in standard cultivar. With the exception of 'Vranjska' and 'Pazardzijska', the other cultivars had significantly higher yields tree(-1) and unit area(-1) than the standard cultivar. Although 'Leskovacka' had the lowest yields tree(-1) and unit area(-1), due to low vigour, it had higher yield efficiency than most of the studied cultivars. Based on the cropping potential, for commercial growing 'Triumph' and 'Portugal' can be recommended. Also, these cultivars are good starting material in quince breeding and creating new cultivars of high cropping potential.

AB  - In this research, morphological characterization of vineyard peach collection was conducted. In 78 accessions thirty qualitative traits of tree, flower, leaf, fruit and stone were analysed by using UPOV and ECPGR descriptors. Most of the studied traits showed a high degree of variability. The lowest variability obtained for the leaf traits, and highest for skin and flesh colour. Not only were the accessions sorted into a large number of categories by the most of their properties, but also there was a significant level of variability in the collection, reflecting in the fact that the traits were recombinant in a different way. Principal component analysis (PCA) and a dendrogram were performed to determine relationships among accessions and to obtain information on the usefulness of those characters for the discrimination. The PCA revealed that the first 4 principal components were able to represent 43.1% of total variance. Traits with high discriminating values comprised internal and external fruit colour, flower type and colour, flower bud density and stone shape. The cluster analysis showed that the accessions were placed in three main clusters. The greatest impact on the separation in clusters had fruit over colour and extent of fruit over colour. Moreover, the collection can also comprise some accessions with the preferred recombination of properties that might be interesting for further studies in breeding.

AB  - The effects of two plant hormones (auxin -IAA and gibberellin - GA(3)) on pollen germination and pollen tube growth in vitro were investigated in five almond cultivars: 'Tuono', 'Nessebar', 'Ferragnes', 'Ikar' and 'Exinogard' during 2014 and 2015. Germination rate and pollen tube growth were determined on a culture medium containing 15% sucrose and 0.7% agar. Pollen germination in the control variant (without application of hormones) ranged from 23.56% ('Ferragnes') to 51.81% ('Tuono'). Plant hormones mainly influenced an increase in pollen germination. The more pronounced effect of plant hormones was manifested on the length of pollen tubes. Thus, in the pollen treated with auxin, length of pollen tubes increased by 23 to 86%, and in pollen treated with gibberellins by 6 to 22%, depending on the cultivar. The exception was only the cultivar 'Nessebar' in which the gibberellin influenced the decrease in the length of pollen tubes.

AB  - The effect of three different temperatures (5, 15 and 25 degrees C) on pollen germination and pollen tube growth in vitro was studied in six apricot cultivars: 'Goldrich', 'Hungarian Best', 'Laycot', 'Novosadska Rodna', 'Pisana' and 'Sylred'. Germination rate and pollen tube growth were determined on a culture medium containing 15% sucrose and 0.7% agar. Temperature significantly affected pollen germination of all studied cultivars. High germination rates (41-84%) were obtained at 15 and 25 degrees C. Germination rates at 5 degrees C were significantly lower than those at higher temperatures. However, germination rates at 5 degrees C were significantly higher in early-flowering cultivars ('Laycot', 'Sylred' and 'Goldrich') compared to late-flowering cultivars ('Novosadska Rodna', 'Hungarian Best' and 'Pisana'). The influence of temperature was more prominent on the pollen tube growth. The length of pollen tubes was six to twelve times higher at 15 and 25 degrees C, respectively, in comparison with those recorded at 5 degrees C. The obtained results indicate differential cultivar response to the temperature during the pollination period.

AB  - Morphological characterization of pollen grains is very important in the identification of individual species and cultivars of fruit trees, including quince. As material for these studies, the pollen of eight quince cultivars, Leskovacka, Vranjska, Morava, Pazardzijska, Hemus, Asenica, Portugal, and Triumph was used. During the 3-year study period (2010-2012), using scanning electron microscopy (SEM), the following characteristics were investigated: the size and shape of pollen grains (length, width, and length-to-width ratio), colpus length, colpus width, mesocolpium width, and characteristics of exine pattern [number of ridges per area (100 mu m(2)) at the equatorial region of exine, ridge width, and furrow width]. The tested quince cultivars differed significantly in terms of morphological characteristics of pollen. The exceptions were colpus and mesocolpium width, as well as the ridge and furrow width on the exine, which showed no statistically significant difference. Pollen grains of quince are characterized by great length (over 53 mu m). The shape of pollen grains varied from prolate (Leskovacka, Vranjska, Morava, Hemus, Asenica, and Triumph) to perprolate (Pazardzijska and Portugal). The exine pattern of all cultivars was striate with longitudinal ridges, which were more parallel in cultivars Vranjska, Hemus, Portugal, and Triumph and less parallel in cultivars Leskovacka, Morava, Pazardzijska, and Asenica. Three groups of similar cultivars are separated on the basis of hierarchical cluster analysis results. Some pollen morphological characteristics, such as the size and shape of pollen grains and colpus length, can be used in the identification of quince cultivars.

AB  - The effect of three different temperatures (8, 16 and 24°C) on pollen germination and length of pollen tube in vitro was investigated in four pear cultivars ('Butirra Precoce Morettini', 'Williams', 'Conference' and 'Abate Fetel'). The temperature showed a significant effect on in vitro pollen germination. The highest pollen germination was determined at a temperature of 24°C (53.25%), somewhat lower at 16°C (44.72%) and the lowest at 8°C (23.16%). The temperature effect was significantly more pronounced on the length of pollen tube. Pollen tube length was about three times higher at the temperatures of 16 and 24°C compared to 8°C. The temperature of 8°C was not sufficient for pollen germination and pollen tube growth in pear cultivars. However, temperatures of 16 and 24°C were optimal for pollen germination and pollen tube growth.
AB  - U ovom radu ispitivan je uticaj tri različite temperature (8, 16 i 24°C) na klijavost polena i dužinu polenovih cevčica kod četiri sorte kruške (Rana Moretinijeva, Vilijamovka, Konferans i Fetelova). Temperatura je ispoljila značajan uticaj na klijavost polena. Najveća klijavost polena je utvrđena na temperaturi od 24°C (53,25%), nešto manja na 16°C (44,72%), a najmanja na 8°C (23,16%). Uticaj temperature je bio znatno više izražen na dužinu polenovih cevčica. Dužina polenovih cevčica je za oko tri puta bila veća na temperaturama od 16 i 24°C u odnosu na 8°C. Temperatura od 8°C nije dovoljna za klijavost polena i rast polenovih cevčica sorti kruške. Međutim, temperature od 16 i 24°C su optimalne za klijavost polena i rast polenovih cevčica.

The highest pollen germination was determined at a temperature of 24°C (53.25%), somewhat lower at 16°C (44.72%) and the lowest at 8°C (23.16%). The temperature effect was significantly more pronounced on the length of pollen tube. Pollen tube length was about three times higher at the temperatures of 16 and 24°C compared to 8°C. The temperature of 8°C was not sufficient for pollen germination and pollen tube growth in pear cultivars. However, temperatures of 16 and 24°C were optimal for pollen germination and pollen tube growth., U ovom radu ispitivan je uticaj tri različite temperature (8, 16 i 24°C) na klijavost polena i dužinu polenovih cevčica kod četiri sorte kruške (Rana Moretinijeva, Vilijamovka, Konferans i Fetelova). Temperatura je ispoljila značajan uticaj na klijavost polena. Najveća klijavost polena je utvrđena na temperaturi od 24°C (53,25%), nešto manja na 16°C (44,72%), a najmanja na 8°C (23,16%). Uticaj temperature je bio znatno više izražen na dužinu polenovih cevčica. Dužina polenovih cevčica je za oko tri puta bila veća na temperaturama od 16 i 24°C u odnosu na 8°C. Temperatura od 8°C nije dovoljna za klijavost polena i rast polenovih cevčica sorti kruške. Međutim, temperature od 16 i 24°C su optimalne za klijavost polena i rast polenovih cevčica.",

AB  - The results of two-year research (2011-2012) of the most important morphological characteristics of 1-year-old shoots in eight peach hybrids obtained from a crossing combination Flaminia x Hale Tardiva Spadoni were shown in this paper. The following characteristics were studied in tested hybrids: length and diameter of shoots, internode length, number of flowers and vegetative buds per shoot, ratio of flower to vegetative buds, number of flower buds per node and 1-m length of a shoot. The properties of sylleptic shoots on one-year-old shoots have also been studied. The significant differences were determined among the hybrids for parameters such as the diameter of shoots, internode length, number of flower and vegetative buds per shoot. Hybrids FH1 and FH6 were characterized by the highest density of flower buds, so that they are singled out as potentially the most yielding. These hybrids may be of interest for growing in areas where there is a risk of frost and in the domain of breeding when creating new peach cultivars of high yield potential.
AB  - U ovom radu prikazani su rezultati dvogodišnjih istraživanja (2011­2012) najvažnijih morfoloških osobina mešovitih rodnih grančica kod osam hibrida breskve dobijenih iz kombinacije ukrštanja Flaminia x Hale Tardiva Spadoni. Kod ispitivanih hibrida proučavane su sledeće osobine: dužina i prečnik grančica, dužina internodija, broj cvetnih i vegetativnih pupoljka po grančici, odnos cvetnih i vegetativnih pupoljaka, broj cvetnih pupoljaka po nodusu i 1 m dužine grančice. Takođe su proučavane i osobine prevremenih grančica koje se nalaze na mešovitim rodnim grančicama. Za parametre kao što su prečnik grančice, dužina internodija, broj cvetnih i vegetativnih pupoljaka na grančici utvrđene su značajne razlike između ispitivanih hibrida. Hibridi FH1 i FH6 su se odlikovali najvećom gustinom cvetnih pupoljaka, tako da su oni izdvojeni kao potencijalno najrodniji. Ovi hibridi mogu biti interesantni za gajenje u područjima gde postoji opasnost od pojave mrazeva i u oplemenjivanju prilikom stvaranja novih sorti breskve visokog rodnog potencijala.

AB  - Pollen germination and pollen tube growth in vitro in eight quince cultivars (ʻLeskovackaʼ, ʻVranjskaʼ, ʻMoravaʼ, ʻPazardzijskaʼ, ʻHemusʼ, ʻAsenicaʼ, ʻPortugalʼ and ʻTriumphʼ) were studied in the three-year period (2010-2012). Agar-plate method with three different concentrations of sucrose (10%, 15% and 20%) was applied. Statistically significant differences between quince cultivars were found in terms of pollen germination and pollen tube length. The highest germination rate was found in 15% sucrose (78.72% in average). Slightly lower germination was found in 20% sucrose (78.52%), while the lowest germination was determined in 10% sucrose (73.76%). Among quince cultivars, the highest germination rates were found in ʻTriumphʼ and ʻAsenicaʼ, and the lowest in Leskovacka. Increasing the concentration of sucrose increased the pollen tube length (from 1435.8 μm in 10%, followed by 1790.7 μm in 15% to 2077.5 μm in 20%). Pollen tube length in 20% sucrose concentration ranged from 1770.3 μm (ʻVranjskaʼ) to 2574.4 μm (ʻAsenicaʼ). Based on obtained results, the sucrose concentrations of 15% and 20% can be recommended as optimal for pollen germination of quince cultivars.
