In the life cycle of plant- seed germination and seedling growth are critical stages, especially under conflicting abiotic stress. Seed germination negatively affected by stress condition, the seed priming techniques have been used to improve germination in many field crops under stressed conditions. An experiment was conducted in order to evaluate the effect of red seaweed extract of Gracilaria corticata J Ag., Kappaphycus alvarezii and mixture of both as a biopriming agents, that alters the responses of vegetables seeds germination under water stress. In hydropriming treatment seeds were treated with water, in biopriming treatment different dosages of red seaweed extracts were used and untreated seed used as a control. The present paper indicates the seed parameters such as germination percentage, germination index, mean germination time, seedling length, radical length, plumule length, seedling vigour index and seed stamina index are found to be positive effect by priming treatment and biopriming treatment was better than hydropriming treatment as compare to control.
