| Abstract: | The paper mainly studied the toxic effects of single Cd and interaction of Cd with Zn on [ Oenanthe javanica (Blume) DC].The cadmium concentration acetates was 0.1,1,10,50,100?mmol/L.5?mmol/L zinc was added to every single cadmium treatment. we measured the following physiological indexes: chlorophyll content, activity of peroxidase and nitrate reductase, soluble protein et al . Our conclusion was that : on the content of superoxide anion zinc showed a synergism with cadmium; while the other indexes zinc showed an Antagonism with cadmium when w Zn / w Cd >1/2,and Synergism when w Zn / w Cd <1/2. |
