Abstract:
Using cowpea as test materials，under the stress condition of 300 mmol/L NaCl，the influence of different concentrations of chitosan solution on cowpea seedling growth were studied.The results showed that chitosan treatment could improve the plant height and stem diameter significantly and promote seedling morphogenesis.And the SOD and POD activity were significantly higher than the control，MDA content and electrolyte leakage reduced significantly.The chitosan solution could alleviate the symptoms of salt injury of cowpea seedling，improve the salt tolerance in the appropriate concentration range.And the effect were the best when the chitosan solution concentrations were 200-250 mg/L.
