Seven days old seedlings of groundnut (Arachis hypogeae) were exposed to UV-C rays for 5 days. After 30 days seedlings exposed to UV-C rays showed increased root length, root nodules and decreased shoot length as compared to control plants. A significant reduction in carbohydrate, total protein, amino acids and secondary metabolites in UV-C exposed seedlings was observed. Chlorophyll a and b, and carotenoids contents were found to be decreased in UV-C treated plants. The nitrogen-fixing ability of the Rhizobium bacteria was negligible.
