Online published on 2 January, 2017. Abstract Benzyladenine is adenine-type cytokininsthat play various roles in many aspects of plant development and stimulate anabolic processes in plant cells. Water deficit stress was imposed on groundnut (Arachis hypogaea L.) at different growth stages viz., water stress at vegetative stag (20 days after sowing), pegging stage (45 days after sowing) and at pod development stage (65 days after sowing). Stress was imposed for 20 days. The aim of this study was to examine the effect of benzyladenine and water deficit stress on osmolytes, such as proline, ascorbic acid, total soluble sugars and reducing sugars at different growth stages. Water stress increased the proline, amino acids, total soluble sugarsand reducing sugars content in the leaves. Seed soaking treatment of hormones stimulated accumulation of all these metabolites, especially under water stress in all the varieties. Stress-induced increase in amino acids, particulary of proline and soluble sugars, might be responsible for osmotic adjustment. Seed soaking treatment of benzyladenine could alleviate adverse effect of water stress partly in all the three varieties i.e. GG 2, GG 7 and J 11.
