Abstract
Priming of seeds in 150 mM KCI at $10^{\circ}C$ for 6 days was most effective in increasing germination rate and shortening germination time. Germination rate of primed seeds was increased to 96% which is about 14% higher than that of non-primed seeds. Germination temperature for better priming effects from primed onion seeds was 10 to $15^{\circ}C$ which is relatively lower than that of normal germination temperature of $20^{\circ}C$. Drying primed seeds at $20^{\circ}C$ for 5 hours resulted in best priming effects.
