All heavy metals are potentially toxic at elevated concentrations. Effects of Mercuric Chloride on the morphological parameters such as germination percentage, root length, shoot length, number of leaves, fresh and dry biomass, pigments, Carbohydrate, Protein and Amino acids were analyzed during investigation on 10th day seedlings of Vigna mungo L., All parameters exhibited reduced trend with increase in HgCl2 concentrations when compared to control plants. However, Protein content in shoot and root of the seedlings showed a different trend by increasing the content with the increase in heavy metal concentration. This indicates that, the seedlings are in the process of increase in tolerance to HgCl2 treatment. Metal toxicity affects crop yields, soil biomass and fertility.
