Studies on evaluation of toxic effect of Cajanus cajan grown under the metal stress condition

The effects of metal chloride salt on seed germination, root, shoot length and dry biomass of cajanus cajan was evaluated under laboratory conditions. The seeds of cajanus cajan (Pigeon pea) were germinated in different concentrations of (0, 15, 10, 20, 50 mg/L) mercuric chloride and cadmium chloride. The germination parameters like germination percentage root and shoot length, fresh and dry weight of 12 days seedlings showed a decreasing trend with the increase in concentration of mercuric chloride and cadmium chloride. Hg and Cd showed significant inhibition of root elongation and the inhibition was more pronounced in the seedlings treated with cadmium.
