Abstract
Studies were conducted to determine the effect on absorption and metabolism of atrazine [2-chloro-4-(ethylamino)-6-(isopropylamino)-s-triazine] by atrazine-susceptible (S) and -resistant (R) biotypes of common lambsquarters (Chenopodium album L.) and redroot pigweed (Amaranthus retroflexus L.). The response of isolated chloroplasts of susceptible and resistant biotypes of each species was also studied. In both species the two biotypes absorbed atrazine equally well and were unable to differentially metabolize the herbicide. The photochemical activity of R chloroplasts isolated from each species was not inhibited by atrazine but S chloroplasts were severely inhibited.This publication has 10 references indexed in Scilit:
