The present study was conducted to identify the effects of some priming treatments, viz. polyethylene glycol (PEG), indole-acetic acid (IAA), abscissic acid (ABA), PEG + IAA, PEG + ABA on germination and seedling growth in two commonly grown mungbean cultivars, Pratap and IPM99-125 which differed in their response to drought. Primed seeds were further fed for evaluation of different seedling morphophysiological characteristics. The study confirms the positive effect of priming on germination stage of mungbean, irrespective of the cultivars. Significant differences were noted for the applied treatments in both the cultivars, the best being PEG and PEG + IAA for cultivar Pratap (drought-resistant) and IPM99-125 (drought-susceptible) respectively.
