摘要: The first step in appearance of herbicide-resistant weed populations is the resistant plants or mutants. While efforts are underway to study and predict spread within populations, knowledge conditions prevailing at time misunderstood. We try shed some light on this phenomenon using example atrazine-resistant common lambsquarters. population structure variability, presence unusual genotypes that have a high mutation rate, occurrence low-dose phenotype precursor high-dose phenotype, potential for multiplication shown be major importance behavior herbicide resistance. Nomenclature: Atrazine 6-chloro-N-ethyl-N'-(l-methylethyl)-1,3,5-triazine-2,4-diamine; lambsquarters, Chenopodium album L. #3 CHEAL. Additional index words: Herbicide resistance, mutants,
