摘　　要：Paraquat(1,1’-dimethyl-4,4’-bipyridinium dichloride,PQ)has been widely used as a broad spectrum nonselective herbicide in agriculture for decades(Baldwin et al.,1968).Plants absorb PQ from their environment and transport to the chloroplasts,the site of its action where it competes for electrons from photosystem I(PSI)and cyclically generates superoxide that is converted to H2O2by superoxide dismutases(SODs),resultantly accumulating a large amount of reactive oxygen species(ROS)and thereby killing plants(Farrington et al.,1973).

关 键 词：thereby converted RESULTANT
