Abstract:
Lycium ruthenicum seedlings were chosen as test material,effect of different concentration of NaCl (0,200,400 mM )on seedling growth and physiological property of Lycium ruthenicum were studied.The results showed that the values of relative electrolyte leakage in roots increased significantly during the period of NaCl treatment;After NaCl treatment for 14 days,the contents of H2O2 and MDA did not change much as compared with the control;The content of soluble sugars decreased significantly in roots after 7 days of NaCl treatment，while the content of soluble protein declined after 14 days of NaCl exposure;Under different concentrations of NaCl treatment,POD activity in both leaves and stems declined dramatically after 7 and 14 days of treatment.According to the results obtained,the leaves and the stems posses relatively higher salt tolerance，while the root was relatively sensitive to salt stress.
