Abstract: Heat stress is a major problem raised in agriculture sector due to increasing temperature in temperature. Due to Increase in temperature plant en counter physiological and biochemical changes which directly affect plant growth and production. There are multiples method of seed treatment for improving heat stress tolerance during seed germination for better growth and production. There are different biotic and abiotic stresses throughout plant ontogeny. To overcome these stresses different approaches have been made and practiced, there are few methods that are still in research in different research institute. The negative effects of heat stress can be reduced by developing plant extracts through the development of thermo tolerance using a variety of genetic methods. For this purpose, however, a complete understanding of plant life responses to high temperatures, heat tolerance methods and possible techniques for improving plant heat tolerance is essential. Some treatment can be particularly time consuming, while other treatment are denied by countries in the world.
