Abstract
Changes in chlorophyll content,composition of chloroplast protein and root meristems protein in rye and maize treated by AmiprophoseMethyl(APM) and Atrazine were studied.Results revealed that for the concentrations of 0.1mg·L-1 and 1mg·L-1 Atrazine,chlorophyll contents of rye decreased from 1.72±0.034mg·g-1 FW(control) to 1.62±0.05mg·g-1 FW and 1.25±0.015mg·g-1 FW,respectively.Both kinds of herbicides could induce the protein composition changes of root meristems in rye and maize,when rye and maize were treated with 0.1mg·L-1 Atrazine,4 protein spots,spot7,spot18~20 were induced and 12 protein spots,spot6,spot8~17 and spot21 were lost in root meristems of rye,4 protein spots,spot5,spot14~16 were induced and 4 protein spots,spot17~20 were lost in root meristems of maize.2 protein spots,spot19~20 were induced and 13 protein spots,spot1~13 were lost in chloroplast of rye,however,Atrazine could not cause the contents of chlorophyll and chloroplast protein composition changes in maize.For the concentration of 4mg·L-1 APM,1 protein spot,spot1 was induced and 4 protein spots,spot2~5 were lost in root meristems of rye,and 15 protein spots,spot4~5,spot7~16,spot21~23 were induced and 4 protein spots,spot1~3,spot6 were lost in root meristems of maize.No effect of APM on the contents of chlorophyll and protein compositions of chloroplast was observed in two crops.
