摘 要：The effect of 24-epibrassinolide on growth of pigeon pea [Cajanus cajan (L.) Millsp.] under aluminium toxicity was studied. 24-EBL reduced the impact of Al stress on plant growth. Particularly 24-EBL reduced the inhibitory impact of aluminium toxicity on root growth which was further manifested in overall improvement of vegetative growth. Application of 24-epibrassinolide removed the inhibitory influence of Al nodulation. The growth stimulation in Cajanus plants by 24-EBL under Al stress was associated with elevated levels of chlorophylls, nucleic acids and soluble proteins. 24-Epibrassinolide application enhanced proline content in Al3+ stressed Cajanus plants. Further, the supplementation of 24-epibrassinolide to Al stress treatments increased the activities of antioxidative enzymes viz., catalase [EC 1.***.1.6];peroxidase [EC 1.***.1.7];superoxide dismutase [EC 1.***.1.1] and ascorbate peroxidase [EC 1.***.1.11]. Lipid peroxidation induced by Al was found reduced with the supplementation of 24-epibrassinolide. The present studies demonstrated the ameliorating capability of 24-epibrassinolide on the Al induced inhibition of plant growth of C. cajan.
