Abstract : The present work was conducted to study the effects of Cd metal on morphological parameters (root length, shoot length and number of leaves), activities of antioxidative enzymes (guaiacol peroxidase, catalase, superoxide dismutase, ascorbate peroxidase, glutathione reductase, dehydroascorbate reductase and mono-dehydroascorbate reductase), protein content, MDA content, proline content and glycine-betaine content in 30-days old plants of Brassica juncea as these plants are hyper-accumulator of Cd metal. Findings of present study were revealed that root length, shoot length and number of leaves lowered under different concentrations of Cd treatment while activities of antioxidative enzymes and osmolytes content were found to enhance. The observations indicated that the defence system of plant was activated under metal stressed conditions.
