Effect of Toxic metals on Seed Germination of Rheum emodi (Wall. Ex Meissn), a Rare Medicinal Plant of Garhwal Himalaya

Abstract

Rheum emodi is a rare medicinal herb in the Himalayan region due to its medicinal cum aromatic properties it is highly over-exploited from nature. Complete Randomized Design was executed and study aimed to understand the effect of different concentration of Lead and Cadmium in growth and biochemical parameters of Rheum emodi (Wall. Ex Meissn) as comparison to control. In plants, heavy metals Quantity were analyzed to show their effects on the animal and human beings who consume them as such or their derived products. In this study, encouraging results were obtained which favoured maximum (53.33%; p<0.05) mean germination in control and minimum in 1.5g concentration in both case of Lead and Cadmium treatment.
