Abstract: Background and Objective: Rapid germination is very important for better plant growth and development under stress condition. The increase in soil and water temperature reduces seed germination ability, germination speed and hence resulting into poor seedling vigor and plat growth. This study was conducted to investigate to what extent the seed enhancement technique helped to improve the rice seed germination and seedling establishments on the effect of high soil temperature stress. Methodology: Four rice seeds varieties were primed with PEG 6000, hydropriming and non-primed seeds were used as a control. After priming, germination test under soil temperature stress of 36°C (room-control), 40, 43 and 46°C was performed in greenhouse condition to evaluate the stress effect on germination and seedling quality. Results: The results showed highly significant difference on maximum germination (max G, %), mean germination time (MGT%), time to attained 50% germination (T50%), germination energy (GE), shoot and root growth and development at different soil temperature stress between primed and non-primed seeds. Conclusion: Primed seed promote rapid germination as well as shoot and root growth under high soil temperature (40-43°C). However, growth and development were ceased at above 43°C. Furthermore, high soil temperature and priming techniques promoted root and shoot growth than to non-primed seeds.
