Chinese cabbage plants exposed to different concentrations of Uranium⌈ in water culture were used to discuss the physiological and biochemical responses:the plant height growth rate, root elongation, superoxide dismutase(SOD), catalase(CAT), Peroxidase(POD), Chlorophyll a, Soluble protein. The results show that high Uranium stress can hinder the plants growth because the plant height growth rate and root elongation of the plants treated with high Uranium concentration were both lower than the control group. Exposure to excess concentration of ...
