Abstract:
Effects of different perchloroethylene（PCE）concentration on biological indexes of soybeans seedlings were studied by using simulated experiment in laborotary. Results showed the contents of MDA、O2,proline and GSH in soybean seedlings all increased as the PCE stress strenthened, and obvious dose-effect relationships between them were found. The proline and GSH contents increased evidently when PCE concentrations were above 0.30 mgkg-1. When PCE concentrations were above 30.00 mg·kg-1 the O2 and MDA contents increased evidently, and the lipid peroxidation of soybean seedlings strengthened. It was also showed that the activity of SOD and CAT were activated in lower PCE stress, and decreased when PCE concentrations were above 0.30 mg·kg-1.
