We studied the effect of copper stress on the growth and some leaves physiological indexes of Sophora japonica under different concentration treatments by using pot-culture method. The results showed that:the plant height and ground diameter of Sophora japonica exhibited an increasing trend followed by declining with increasing copper stress. When the concentration of copper were 1000 mg·kg-1, the plant height and ground diameter had an extremely significantly difference respectively in comparison with control. When the concentration of copper lower than 500 mg·kg-1, the chlorophyll contents increased rapidly, exhibiting an increasing tendency, and there were no significant difference in comparison with control. The proline contents and superoxide dismutase (SOD) activity increased rapidly, significantly different from the control, and exhibited some adaptability. With increasing concentrations of copper stress (>500 mg·kg-1), the contents of chlorophyll and activities of SOD decreased remarkably, and the MDA, relative conductivity and proline contents ascended sharply, indicating Sophora japonica suffer significant injury.
