The effect of 24-epibrassinolide on seed germination and seedling growth of Cajanus cajan (L.) Millsp. subjected to aluminium stress was investigated. 24-EBL was found to reduce the impact of Al stress on seed germination. Further, the application of 24-EBL resulted in removal of the inhibitory influence of Al on seedling growth. Epibrassinolide application caused enhancement of proline in Al stressed Cajanus seedlings. Further, the supplementation of brassinosteroids to Al stress treatment increased the activities of antioxidative enzymes such as catalase [EC 1.11.1.6]; peroxidase [EC 1.11.1.7]; superoxide dismutase [EC 1.15.1.1] and ascorbate peroxidase [EC 1.11.1.11]. The present studies demonstrated the ameliorating ability of 24-EBL on the inhibition of germination and seedling growth of C.cajan by reducing the oxidative stress.
