AB  - Weedy sunflower Helianthus annuus L. (WS) can become troublesome for cultivated sunflower given their genetic similarity which allows gene flow from weed-to-crop and from crop-to-weed. Also, it causes yield losses in different spring-sown crops. Despite this, there is still no data about its response to herbicides.
Field experiments were conducted to quantify the effects of nicosulfuron on WS populations. Plants of three populations (R1-WS and R2-WS = presumably resistant and S-WS = susceptible) were treated with 40 g nicosulfuron ha-1 at the 2–4 true-leaf growth stage. Vegetative parameters (plant height, fresh weight, leaf area) and relative chlorophyll content (RCC) were measured 30 days after herbicide application. Generative parameters (number of heads plant-1, head diameter, number of seeds plant-1) were measured at maturity. After harvesting, seed germination of collected seeds was studied in Petri dishes at 25°C.
Nicosulfuron was found to have a significant effect on vegetative and generative production of WS plants. The effect on RCC and postharvest seed germination was not so prominent. All this effects depended on the population, which is probably a result of different history of herbicide application and possible development of resistance in the populations R1-WS and R2-WS.

AB  - Weedy forms of cultivated sunflower (Helianthus annuus) are invasive species widely distributed in several regions of the world and are commonly controlled by applying acetohydroxyacid synthase (AHAS)-inhibiting herbicides, such as imidazolinones (IMIs) or sulfonylurea (SUs). The widespread adoption of herbicide-resistant crops has exposed the weedy population to the high risk of crop-to-weedy gene flow. The aim of this study was to check and quantify the gene flow from IMI- and SU-resistant sunflower hybrids to weedy sunflower populations. Field experiments were conducted in 2008 at two sites in Serbia to evaluate the relationship of distance between the crop and the weedy sunflower and its impact on the percentage of gene flow. The weedy sunflower progenies were evaluated through herbicide resistance and SSR marker study. Hybridization with IMI-resistant hybrids was not confirmed. Conversly, SU-resistance trials and SSR marker studies partially confirmed the transfer of resistance within the weedy population.

AB  - The response of two populations (CC1, 43.59 degrees N & 20.40 degrees E; CC2, 44.46 degrees N & 20.17 degrees E) of common cocklebur (Xanthium strumarium L.) to nicosulfuron was investigated both in field experiments and in the laboratory. Population CC1 had no history of treatment with any herbicide, while population CC2 was treated with ALS inhibitor herbicides for six consecutive years. In the field, plants were treated post-emergence with nicosulfuron (0, 10, 20, 40, 60 and 80 g ai ha(-1)) at four true leaves. Visual injury estimation and vegetative parameters (plant height, fresh weight, leaf area) were recorded about month after herbicide application. The acetolactate synthase (ALS) enzyme activity in response to herbicide concentrations of 0, 0.01, 0.1, 1, 10, 100 mu M was determined in vitro. GR(50) values for vegetative parameters and 150 values for ALS activity were slightly greater for the CC2 than for the CC1 population, but the results confirmed that neither population was susceptible to nicosulfuron. Namely, based on results for fresh weight, the population CC1 was about 3.9 and 2.6-fold more susceptible CO nicosulfuron than population CC2 in two consecutive years, but differences were not so prominent for other parameters (plant height, leaf area and ALS activity), ranging from 1.18 to 1.8-fold. The differences between population CC1 and CC2 could be attributed to inter-population variability in susceptibility CO nicosulfuron or could be the consequence of repeated application of ALS herbicides to the CC2 population during the six previous years. Future investigations are necessary in order to clarify this dilemma.

AB  - Field experiments were conducted in 2008 and 2009 at the Experimental Field Institute Padinska Skela PKB Agroekonomik, near Belgrade, to quantify effects of nicosulfuron on plant traits (vegetative production and fecundity) of Xanthium strumarium. Plants of X. strumarium were grown in monoculture on plots of 5 x 4.2 m. Inter-row spacing was 24 cm and the distance between the rows was 70 cm. Plants were treated with nicosulfuron when they developed two pairs of leaves. The applied rates of nicosulfuron were 20, 40 and 80 g a.i. ha(-1) and one control treatment (without herbicide application) was included. Vegetative parameters (height, fresh weight, leaf area and leaf area index (LAI)) were recorded just before herbicide application and four times after the herbicide treatment. Measurements were made at intervals of about two weeks. At maturity, fecundity of weeds (bur weight plant(-1) and bur number plant(-1)) was measured. In both years, the application of nicosulfuron caused less growth (height, fresh weight and LAI) of X. strumarium in comparison with the control. All rates of nicosulfuron reduced vegetative parameters, which decreased as rates of nicosulfuron increased. On the other hand, effects of nicosulfuron on bur production were not equivalent to its effects on vegetative parameters. Only the highest rate of nicosulfuron reduced bur production significantly.

AB  - Glyphosate may cause injury to non-target plants. The first detectable symptom after glyphosate treatment is the growth inhibition, followed by noticeable yellowing (chlorosis) of the treated tissue. Five to ten days after the treatment, the chlorosis turns into necrosis and the plants begin to die. Greenhouse research was conducted in 2007 to investigate the response of glyphosate resistant (GR) soybeans PAN 520 line and non-glyphosate resistant EGRET line of soybeans CO glyphosate trimesium sulphosate and to evaluate soybeans injury to help in weed resistance detection. The methods used to detect changes were dose response test, HPLC measurement based on glyphosate induced accumulation of shikimate, and morpho-anatomical changes (light and electron microscopy). Damaged chloroplasts are a clear indication of a glyphosate injury. If the injury rating is related to increased shikimate levels, there is greater certainty that differences among biotypes are due to glyphosate tolerance.

AB  - Changes in leaf anatomy were examined in two S. African populations of Conyza canadensis of which one was presumed to be resistant (CCPR) and the other susceptible (CCS) to glyphosate. Glyphosate was applied to plants, which were grown from seed collected from these populations, at rates of 1, 2 and 4 kg a.e. ha(-1) of TOUCHDOWN [active substance: glyphosate trimesium salt, 500 g L-1] that are equivalent to 2, 4 and 8 L ha (-1) of the herbicide Touchdown. Leaf samples for the light microscope (LM) analysis were collected 3, 7 and 24 h after treatment (HAT). Changes in chlorophyll and shikimate content of leaf material were also examined. Changes in the palisade and pith tissue of leaves were not detected in the investigated populations at 3 and 7 HAT. However, at 24 HAT the different herbicide doses caused changes in leaf anatomy. These changes (injuries) were detected in the CCS at all tested doses, but in the CCPR population of C. canadensis the injuries were observed at only the two highest rates, 2 and 4 kg a.e. ha(-1). Chlorophyll and shikimate contents indicated significant differences between the treated and untreated plants of susceptible population only. Difference in glyphosate resistance between the CCS and CCPR populations was confirmed with an index of resistance of 1.58. This value of the index of resistance indicates that CCS population is 1.58 times more susceptible to glyphosate compared to CCPR population.

AB  - A better understanding of the seed ecology can be helpful for prediction of the potential of weed species to spread, for prediction of their invasiveness, and for development of more effective weed management strategies. In Serbia, in agricultural areas, edges of crop fields, as well as in uncultivated areas, more and more populations of common cocklebur (Xanthium strumarium L.) were detected. Seeds from two populations (P-1 and P-2) of this species were collected for testing temperature effects on germination. Germination tests were conducted in an incubator set to 10, 15, 20, 25, 30 and 35 degrees C, in the dark. The seeds were considered to be germinating at the moment of radicle emergence. The number of germinated seeds was recorded daily (germination rate) during 7 day period and germination rate (sum of germinations per day) was calculated. Final percentage of germination and seedlings length and weight were measured after 7 days of incubation. Seeds of the both common cocklebur populations did not germinate when incubated at 10 degrees C. The lowest germination occurred at 35 degrees C for population PI and at 15 degrees C for population P-2, while the maximum germination occurred at 25 degrees C for both populations. The highest length of seedlings were recorded at 25 degrees C and 30 degrees C for population P-1 and P-2, respectively, while the highest seedlings weight was at 35 degrees C for both populations. The lowest seedlings length, as well as weight, was measured at 15 degrees C for both populations.

AB  - BACKGROUND: A Chenopodium album L. biotype surviving in atrazine-treated Serbian corn fields (VC) was compared against atrazine-susceptible (S) and atrazine-resistant (R) standards. RESULTS: Atrazine (2 kg ha(-1)) killed S and VC shoot biomass 15 days after treatment (DAT), but R was only suppressed by 42% and survived 8 kg ha(-1). Atrazine at 2 kg ha(-1) only inhibited VC height by 60% as against 100 and 0% for S and R respectively. Chlorophyll fluorescence (Fv/Fm) and transpiration were insensitive to atrazine in R, but were inhibited by 90 and 100% in S and by 50 and 60% in VC respectively. Decline of Fv/Fm after 2 kg ha(-1) atrazine was stabilized at 3 DAT for the VC biotype. CONCLUSION: A toxicity mitigation mechanism could have facilitated VC survival in an atrazine-treated field. Further knowledge on this mechanism is needed to establish if surviving VC plants are indicators of atrazine resistance evolution in these Serbian corn fields. Variables related to foliar function provided better detection of weed mechanisms to survive herbicide action than the usual shoot biomass measurements.

AB  - A possibility of using physiological parameters for differentiating resistant and susceptible plants was investigated. Intensity of transpiration diffusive resistance and chlorophyll concentrations were measured. The experiments were carried out in the greenhouse. Seeds were collected from an area continually treated with atrazine over a period often years (locality Veliki Crljeni) and from treatment-free fields (locality Belgrade). A referent resistant population was obtained from Great Britain. Atrazine was applied (2,4 and 8 kg/ha) when plants were in a 2-4 leaf growth stage. Parameters were measured on the 7th and 15th post-treatment days. The results showed no significant change in the physiological parameters of the treated referent plants. On the other hand, treated plants from the localities of Veliki Crljeni and Belgrade showed a significant decrease in the intensity of transpiration and chlorophyll concentration, and increase in diffusive resistance, compared to untreated plants. Comparing the parameters analyzed, statistically significant differences were found between the domestic populations and the resistant referent population. Based on the variations found in plant responses to atrazine treatments (intensity of transpiration and diffusive resistance) in the populations investigated, we believe that assessment of these physiological parameters alone cannot provide sufficiently reliable data for differentiating between resistant and susceptible plants.
AB  - U radu je ispitivana mogućnost korišćenja fizioloških parametara kao osnove za razdvajanje rezistentnih od osetljivih populacija Chenopodium album L. na atrazin. Praćeni su intenzitet transpiracije, otpor prema difuziji i relativni sadržaj ukupnog hlorofila. Semena su prikupljena sa površine na kojoj je atrazin korišćen 10 godina (lokalitet Veliki Crljeni) i sa površine na kojoj nikad nisu primenjivani herbicidi (lokalitet Beograd). Referentna rezistentna populacija dobijena je iz laboratorije iz Velike Britanije. Biljke su gajene u kontrolisanim uslovima i tretirane atrazinom (2, 4 i 8 kg/ha) u fazi 2-4 lista. Promene ispitivanih parametara su merene 7. i 15. dana od primene atrazina. Dobijeni rezultati su pokazali da kod referentne rezistentne populacije tretirane herbicidom nema značajnih promena na nivou posmatranih parametara. Međutim, kod populacija sa lokaliteta V.Crljeni i Beograd došlo je do značajnog smanjenja intenziteta transpiracije i relativnog sadržaja hlorofila, i do povećanja otpora prema difuziji. Statistička obrada podataka je pokazala da se na osnovu svih parametara može izvršiti razdvajanje osetljivih i rezistentih populacija Ch. album prema atrazinu, s tim što se relativni sadržaj ukupnog hlorofila u poređenju sa druga dva parametra pokazao kao pouzdaniji parametar. Prirodna dnevna dinamika fizioloških procesa i njihova zavisnost od velikog broja činilaca (sadržaja 07 i CO, u vazduhu, vlažnosti vazduha, otvorenosti stoma i sl.) umanjuju pouzdanost intenziteta transpiracije i otpor prema difuziji kao parametara.
