Abstract:

Ensuring rice yield is one of the key measures to cope with the global population growth and food crisis. The probability of high temperature weather in the panicle differentiation stage of rice is increasing, which poses a great threat to the safety of rice production in this region, so it is of great significance to carry out relevant research. In this paper, the effects of high temperature on young panicle formation, anther structure, pollen development, yield and quality, physiological indexes and metabolic regulation mechanism of rice during panicle differentiation were reviewed, and corresponding mitigation measures were put forward, in order to provide a basis for the study of rice stress physiology and the reasonable selection of mitigation measures.

Key words: rice, panicle initiation stage, high temperature, mitigation measures
