The present work aimed to investigate the effect of HgCl2, CdCl2 (50, 200 μg/ml) and SeO2 (0.4, 2.6 μg/ml) singly or in mixtures on yield parameters, biochemical analysis of seeds and protein pattern of Vicia faba L. plants (cv Sakha 1). Heavy metal salts caused a reduction in production and yield parameters as compared to control. Applying selenium dioxide was highly significant attenuated the sever drop of yield parameters. Applying low selenium dioxide to stressed plants increased both sucrose and starch contents to a great extent which more appeared at lower than higher heavy metal levels, but the adverse effect was observed with high selenium dioxide which more pronounced at higher than lower levels of heavy metal salts as compared to single heavy metal salts. The results of protein pattern showed considerable effects of heavy metal stress on protein bands. Selenium dioxide induced the synthesis of new bands and increased the intensity of the original protein bands.
