Abstract:

Under the background of global warming, high temperature weather occurs frequently, heat injury have become one of the main problems that seriously affect high and stable yield of rice. The research progress on the effects of high temperature stress on the growth and development, spikelet fertility, reactive oxygen species accumulation and membrane damage, photosynthesis, endogenous plant hormones, yield and quality of rice were summarized. The defense countermeasures against high temperature hazards of rice had been proposed, including breeding of heat-resistant rice varieties, rational adjustment sowing date, strengthening of water and fertilizer management in paddy fields, rational application of plant growth regulators and other substances. To provide scientific support for the development of heat-resistant rice cultivation and breeding of heat-resistant rice varieties, the future research direction of rice heat injury was prospected.

Key words: rice, high temperature stress, growth and development, injury effect, sowing date, water and fertilizer management, plant growth regulator
