Abstract The ameliorating effects of exogenous hormone and calcium were investigated in salt-stressed black mustard seedlings (Brassica nigra L.). The seedlings were subjected to various treatments: control (nutrient solution), salt stress, kinetin/abscisic acid (ABA)/calcium chloride (CaCl2). Sodium chloride (NaCl) inhibited shoot length (45-55%) and root (<75%). Further, alterations in superoxide dismutase and catalase activities were consistent with changes in levels of reactive oxygen species and malondialdehyde (MDA). The beneficial effects of ABA and CaCl2 in ameliorating salt stress may be attributed to the reduction of membrane peroxidation and increased glutathione (GSH) levels. These observations suggest that oxidative stress resulting from salt stress in B. nigra may result in production of antioxidative enzymes to counteract oxidative damage, and the enzymes may contribute to the ability of B. nigra to survive adverse conditions. Data indicate that hormone and ion in the order of kinetin > ABA > calcium alleviate the adverse impact of salt on B. nigra.
