The effect of seed priming (150 mM KNO₃ at 20℃ for 4 days) on percent germination and the number of days to 50% for final germination (T_(50)) of tomato (cv. ´Youngsoo´ and ´Wolkwang´) seeds were studied under water or saline stress at 15℃ and 20℃. Seed germination decreased with increasing water and saline stress while primed seeds had a higher percent germination than unprimed seeds at 15℃ and 20℃ in water (-0.4 ㎫) and saline solution (0.6%, 1.0%) of germination media regardless of cultivars. Seed priming resulted in marked reduction in T_(50) and in rapid and uniform germination under adverse conditions. Addition of 100 M GA₃ in priming solution promoted percent germination and shortened T_(50) further at 15℃ and 20℃ under adverse conditions. It was concluded that priming alleviated induced stress during germination.
