Effect of Cd Stress on Growth and Related Physiological Indicators of Radish Seedling

Taking of‘Shengfeng'radish seed as material,using hydroponics method,effect of different concentrations of cadmium stresses on seed germination and seedling growth stage of radish seedlings were studied,in order to provide the theoretical basis for the research of the properties of radish seedling resistance to cadmium and phytoremediation.The results showed that radish seedling root,stem and leaf growth were restrained under cadmium stress,the root and stem affected the worst;malondialdehyde and soluble protein content,catalase and peroxidase activity increased with the increasing concentration of processing;the antioxidant activity reduced with the increasing of concentration of cadmium.
