Water, the most important component of life, is rapidly becoming a critically short commodity for humans and crop production. Limited water supply is one of the major abiotic factors that adversely affect agricultural crop production worldwide. Drought stress influences the normal physiology and growth of plants in many ways. In the present investigation drought induced changes pertaining to antioxidant enzyme activities were analyzed in three peanut varieties (GG 2, GG 7 and J 11). Water deficit stress was imposed for 20 days on peanut (Arachis hypogaea L.) at vegetative, pegging and at pod development stage. Results showed that the activities of these enzymes were significantly increased in drought stress level in leaves of all varieties of peanut. Over all, maximum activity of antioxidant enzymes peroxidase, ascorbate peroxidase, polyphenol oxidase, catalase and superoxide dismutase were recorded under drought conditions which was further increased in BA soaked seed. Seed soaking treatment of BA could alleviate adverse effect of water stress partly in all the three varieties i.e. GG 2, GG 7 and J 11.
