Effect of exogenous application of 24-epibrassinolide on the growth, metabolite content and antioxidant mechanism in geranium [Pelargonium graveolens (L.) Herit] plants growing under cadmium toxicity stress was investigated. 24-EBL reduced the deleterious impact of cadmium toxicity on the plant growth. Foliar application of 24-EBL accounted for restoration of pigment levels and improvement of carbohydrate, nucleic acid and protein contents in geranium plants under cadmium stress. The deleterious impact of cadmium on membrane integrity (measured in the levels of MDA, the product of lipid peroxidation) was found negated by 24-EBL. The ameliorative impact of 24-EBL on cadmium toxicity stress was found associated with elevated levels of proline and enhanced activities of antioxidant enzymes such as catalase, peroxidase, superoxide dismutase and ascorbate peroxidase.
