Lead toxicity in soil has become a global issue due to increase and high demand of safety food. In the present investigation an attempted were made on the toxicity effect of lead acetate on the germinal growth of Black Gram seeds. The seeds were influenced to germinate under various concentration of Lead Acetate (Control, 10 mM, 20 mM, 30 mM, 40 mM and 50 mM). The seed germination root length parameters and total chlorophyll estimation were analyzed. Increasing in the concentration of Lead causes drastic reduction in the seed
germination and also wide influenced in the decreased level of chlorophyll content. The result reflects that the Lead is toxic to crop growth and development.
Keywords: Lead Acetate, Black Gram, Seed germination, Chlorophyll content.
