| Abstract: | The mitigation of toxic effect of Cd2 on Potamogeton crispus L. by exogenous Nd3 was studied. The result shows that activity of antioxidase (SOD, CAT, POD) is decreased, and the content of MDA increased. The content of different concentrations of Nd3 for 5 d significantly improved the activity of SOD, POD and CAT in comparison with toxicity of Cd2 , and ranged from 14.0% ～ 30.0%, 8.8% ～ 47.3%, 4.6% ～ 15.1% respectively. The degradation of chlorophyll and protein is alleviated, and generation of MDA reduced . But with the higher concentration of Nd3 , such ability of Nd3 is weakened. The optimum concentration of Nd3 is 10 ～ 15 mg·L-1. |
