Morphophysiological traits and atrazine sensitivity in Chenopodium album L.
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 agai...
متن کاملReduction of Nitrate and Nitrite in Lambsquarters (Chenopodium album) Biotypes Resistant and Susceptible to Atrazine Toxicity.
The nitrite-reducing activity of the normal susceptible biotype of lambsquarters (Chenopodium album L.) was strongly inhibited by atrazine in the assay medium, both in the case of the in vivo assays of leaf discs in light, and in vitro photoreduction assays of crude extracts. In vitro assays of crude extracts with methylviologen or ferredoxin supplying the reducing potential were not inhibited ...
متن کاملAtrazine Resistance in Chenopodium album: Low and High Levels of Resistance to the Herbicide Are Related to the Same Chloroplast PSBA Gene Mutation.
In Chenopodium album two different levels of atrazine resistance have been found according to following criteria: lethal dose and leaf fluorescence curve. The intermediate (I) phenotype is represented by a low level of resistance and a typical I fluorescence curve. It arose at high frequency, within one generation, after self-pollination of particular plants displaying a susceptible (S) phenoty...
متن کاملContinental Diversity of Chenopodium album Seedling Recruitment
Chenopodium album seedling emergence studies were conducted at nine European and two North American locations comparing local populations with a common population from Denmark (DEN-COM). Mortality risk. Weedy plant life history conforms to the time of mortality risk from either the environment (e.g. frozen soil in the winter) or cropping systems practices (e.g. herbicide use). C. album life his...
متن کاملIntraspecific Competition in Chenopodium album Varies with Resource Availability
-T~~ intensity of intraspecific competition under different levels of light and nitrogen supply was assessed for the temperate zone herb, Chenopodium album. Plants were grown at two densities (one or six plants/pot) in a modified factorial design with three levels each of light and nitrogen availability. This yielded five light/nitrogen treatments which comprised two gradients, one extending fr...
