Effect of cadmium stress on seed germination, plant growth and hydrolyzing enzymes activities in mungbean seedlings

Abstract: Both protein and starch hydrolysis contribute to the effective mobilization of seed reserves trigger germination. We studied activities hydrolytic enzymes in germinating seeds mung bean (Vigna radiata) exposed cadmium stress at 0, 25, 50, 75, 100 mg.L-1. Exposure Cd decreased germination rate early seedling growth traits, including root shoot length plant fresh dry biomass compared control. The adverse effects were more prominent terms than length. Seedling α-amylase protease exhibited significant reductions with increasing dose. also recorded Cd-induced reduction total soluble proteins sugars while concentration free amino acids an increase. Above all, a decrease process reserve carbohydrates, impaired translocation contributed inhibition seedlings’ traits.
