AB  - Changes in leaf anatomy were examined in suspectedly resistant populations of C. canadensis and C. bonariensis after application of 2, 4 and 8 L ha-1 of the product Touch down (500 g a.i. glyphosate L-1). Samples for the analysis (LM, TEM) were collected 3, 7 and 24 h after herbicide application. Changes in chlorophyll and shikimic acid contents were also examined in the populations tested. Changes in the anatomy of leaves were not detected in the investigated populations 3 and 7 h after herbicide application. However, 24 h after application of different herbicide rates, differences were observed in leaf anatomy. Injuries were detected in C. bonariensis population after application of 2 L ha-1, and in C. canadensis population after treatment with the highest glyphosate rate (8 L ha-1). Changes were detected on cell walls, chloroplast lamellae and chloroplasts themselves. Based on chlorophyll and shikimic acid contents, significant statistical differences were detected between the treated and control plants.
AB  - Praćene su promene u anatomskoj građi listova pretpostavljeno rezistentih populacija C. canadensis i C. bonariensis nakon primene 2, 4 i 8 L ha-1 Touch down (500 g a.m. glifosat L-1). Za analizu anatomske građe listova (LM, TEM) materijal je uzorkovan nakon 3, 7 i 24 h posle primene herbicida. Takođe, praćene su promene u sadržaju hlorofila i šikiminske kiseline kod testiranih populacija. Promene u anatomskoj građi listova nisu konstatovane kod ispitivanih populacija nakon 3 i 7 časova posle primene herbicida. Međutim, 24 časa nakon primene različitih količina uočene su razlike u anatomskoj građi listova. Oštećenja su bila uočljiva kod pop. C. bonariensis nakon primene 2 L ha-1, a kod pop. C. canadensis tek nakon primene najveće količine glifosata (8 L ha-1). Promene su uočene na ćelijskom zidu, lamelama hloroplasta, kao i na samim hloroplastama. Na osnovu sadržaja hlorofila i šikiminske kiseline takođe su utvrđene statistički značajne razlike između tretiranih i kontrolnih biljaka.

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. (c) 2007 Society of Chemical Industry.
