Abstract :
Cadmium is a heavy metal which accumulates in soil because of using chemical fertilizers & industrial stir. Heavy metals tension prevents the growth of plants due to mainly disturbance of the balance between production of reactive oxygen species and antioxidant defense and thereby causing oxidative stress. purpose of this study is determine the effect of cadmium on the activity of Superoxide dismutase, Polyphenol Oxydase, catalase and malondialdehyde also the content of Anthocyanin and chlorophyll a and b in were measured.The samples picked up in 30th day and used it for determination of biochemical parameters.the activity of SOD in aerobiosis bodies and CAT in aerobiosis bodies and in roots also Malondialdehyde has been significant increasing in shoot. The cadmium treatment have showed the meaningfull inclucreasing of PPO in 5cadmium and also the significant decreasing in 0.5 cadmium in aerobiosis bodies .Anthocyanin and a and b chlorophylls significant has decreased.
