Influence of benzyladenine on polyethylene glycol-6000 (PEG-6000) induced water deficit stress effect on leaf relative water content (RWC), peroxidase (POX) and polyphenoloxidase (PPO) activities of 15 day old seedlings of groundnut cvs., GG-2, GG-3, GG-4, GG-5, GG-7, and J-11 were studied. Cv. GG-2 was characterized by highest relative water content and higher activities of polyphenoloxidase. The cv. GG-7 had moderate membrane injury and low leaf relative water content. The cv. GG-7 had lower activity of polyphenoloxidase, whereas, cv. J-11 had the lowest relative water content and higher activity of peroxidase. Benzyladenine seed treatment could be positively influenced on the oxidative system. However, the magnitude varied with the cultivars.
