摘　　要：自国际水稻所最先开展耐热水稻品种选育至今近三十几年来,国内外大批学者对于高温灾害评估与预测,耐热水稻品种选育及高温胁迫抗性鉴定,高温胁迫水稻形态发育、产量、品质、生理生化响应及其防御与调控,耐高温胁迫水稻品种遗传改良等方面开展了大量研究,并取得了很大的进展。该综述简要回顾了国内外水稻高温胁迫研究进展,重点评述了高温胁迫对水稻生长的影响,水稻高温胁迫下的生理响应,高温肋迫下其他环境因素对水稻生长的综合效应,以及水稻耐热/热响应的可能分子机制,以期为水稻耐热性研究提供参考。It has been more than thirty years since the first study of high temperature（HT） stress tolerant ricebreeding was carried out by scientists from the International Rice Research Institute（IRRI）. Studies such asdisaster assessment and prediction of HT, HT tolerant breeding, rice plant morphological development, yield,quality, physiological and biochemical responses to HT stress, prevention and control under stress condition,and genetic improvement of rice varieties tolerant to HT have been conducted by scientists worldwide withgreat progress. This article briefly reviews the research progress regarding HT in rice, focuses on reviewing theeffects of HT stress on rice growth and physiological responses, combined effects of other environmental factorswith HT on rice, and possible heat tolerance/heat response mechanisms in rice. This review could provide areference for future studies on HT stress tolerance in rice.
