An experiment was conducted to improve the hot pepper seed performance under salinity stress conditions. The effects of priming with an optimized dose (1 mM) of sodium chloride (NaCl) were assessed for improving seedling vigour and salt stress tolerance in seedlings of the hot pepper. Seeds primed with NaCl solution (1 mM) were examined at different salinity levels [0, 3, 6 and 9 dS m-1] in relation to early growth stage. Priming with NaCl was effective in alleviating the adverse effects of salinity. Significant increase in germination percentage, germination index and germination speed, vigour index, plumule and radicle length, and dry weight of the seedlings as compared to control was recorded. On the other hand, mean germination time, time to reach 50% germination and fresh weight of seedlings were non-significant against control. In this experiment, it was concluded that seed priming with NaCl has been found to be better treatment as compared to non-primed seeds in case of hot pepper for improving the seedling vigour and seedling establishment under salt-stressed conditions.
