摘要: 随着温室效应和极端天气的不断增加,近年来水稻遭遇高温热害的情况频繁发生,研究高温对水稻危害的机理与对策对稳定和促进水稻生产具有重要意义。综述了高温胁迫对水稻生长发育、产量形成和稻米品质的影响,并从光合特性、抗逆系统、脯氨酸、激素、多胺、蔗糖淀粉代谢途径关键酶活性和蛋白质组学等方面阐述了其生理机制,提出减轻水稻高温胁迫的调控措施,并对未来深入开展水稻高温逆境的研究提出建议。

Abstract: With the continuous increase of the greenhouse and extreme weather effect, high temperature occurs more frequently. To understand the mechanism involved in the effect of high temperature on rice growth and to put forward countermeasures to reduce damage of the stress to rice would have great significance in promoting rice production and ensuring food security. This paper  reviewed the effects of high temperature on rice yield and grain quality and its physiological mechanism involved from the aspects of photosynthetic characteristics, stress resistance, proline, hormones, polyamines, enzymatic activities, and proteomics. The regulation techniques to reduce the harms of high temperature and issues for further studies were discussed. 

Key words: rice, high temperature, grain yield, quality, physiological mechanism
