Popis:	A study of pre-germinated seed treatments with soaking, heating, chilling and its integration was conducted on two rice cultivar (viz. Prasad and Pant Sugandha Dhan-15) to explore the possibility of improvement in seed germination and seedling vigour under laboratory condition. The experiment comprised of six treatments and seeds were subjected with soaking, heating (40 °C), chilling (−20 °C), heating followed by chilling and chilling followed by heating after soaking for 24 h along with untreated control. Seed germination and subsequent seedling growth was greatly influenced by soaking, heating and chilling as indicated by statistically higher value of seed germination at first as well as final count and seedling vigour i.e. root, shoot and seedling length, fresh and dry weight of seedling, vigour index, relative growth index (RGI), germination index (GI) and mean daily germination (MDG). Soaking successfully integrated with heating followed by chilling and chilling followed by heating over untreated control for both the rice cultivars while, chilling solely had somewhat lower influence on rice seed invigoration.
