Abstract : In the present work, stress ameliorative properties of Selenium (Se) were studied in Brassica juncea L. plants subjected to Chromium (Cr) stress. B. juncea plants were raised in earthen pots and were treated with different concentration and combination of Se and Cr. The plants were harvested after 60 days and were analysed for morphology, antioxidants (glutathione, ascorbic acid, tocopherol), pigments (chlorophylls a, b, carotenoids, xanthophylls), phenols, flavonoids, glycine betaine, proline and MDA contents. The results suggested that Se treatments proved to enhance the tolerance of the plants to Cr stress.
