Abstract

Today Abiotic stress is a major global problem limiting crop productivity and Stress factors are a serious problem limiting the yield potential of modern cultivars faced by mankind now a days. Stress causes nutritional imbalances in the plant causing reduction in water uptake and toxicity, decreasing the production and Seeds of Eleusine coracana (L.) Gaertn variety PR202 were taken as explants here and inoculated on callus induction medium with varied (Cd(NO3)2 levels (100然, 300 然 and 500 然) Calli were formed in treatments with 100 然 concentration of Cd. Induced Callus were sub cultured on maintenance media and then on regeneration medium (MS + 1mg/l NAA) supplemented with toxic level of heavy metals. Cd above 100 然 concentration was inhibitory for callus induction as well as for plantlet regeneration.
