Abstract:
Sophora tonkinensis Gagnep.seedling was chosen as test material,the protective enzymes activity include super oxide dismasts (SOD)，catalase (CAT)，peroxidase(POD) and malondialde-hyde (MDA) content in leaves were measured when the S.tonkinensis Gagnep.had lived in different concentration of polyethylene glycol (PEG-6000) treatment soil for 60 days,the physiological responses under drought stress and find out the plant drought adaptation of Sophora tonkinensis Gagnep.were studied.The results showed that the MDA content increased and the activity of the protective enzymes had different changes but were notably higher than the normal treatment under different concentration of PEG-6000.The activity of CAT was notably higher under the 15% treatment.The activity of SOD was increased with the increasing concentration of PEG.
