Abstract:
Maize and soybean rotation is very common in north of China. However, the heavy residue of Atrazine，the major corn herbicide is harmful to soybean growth. In order to screen some tolerant varieties and research the mechanism, treated soybean with 250 mg·L-1 Atrazine and determined the activities of peroxidase (POD), polyphenoloxidase (PPO), phenylalanine ammonialyase（PAL）in soybean plants roots and leaves after 0, 24, 48,72 and 96 h. The results showed that POD, PPO and PAL in treated soybean were higher than control and the activities of enzymes in roots reacted early and higher than those in leaves. The enzyme activities of tolerant varieties were higher than sensitive varieties.
