Physiological mechanisms of Brassica juncea L. plants exposed to Cadmium metal stress

Dhriti Kapoor, Renu Bhardwaj

Abstract :

Plants of Brassica juncea L. var. RLC–1 were exposed for 90 days to different concentrations (0, 0.2, 0.4 and 0.6mM) of cadmium (Cd) to analyze the growth (root length, shoot length and number of leaves), level of osmoprotectants (total osmolytes, proline and glycine–betaine content) and activities of antioxidative enzymes (ascorbate peroxidase, glutathione peroxidase and polyphenol oxidase. Results of the present study revealed the decreased growth of Brassica with increasing metal doses. Level of osmolytes was positively influenced by Cd stress and activities of antioxidative enzymes were altered significantly in response to metal treatment. In conclusion, level of osmolytes and antioxidative defence system of plants got activated due to heavy metal stress, which protects the plants by scavenging free radicals.
