摘要:

高温胁迫是影响水稻产量和品质形成的主要环境因素之一。本文概述了高温胁迫对水稻籽粒灌浆和稻米品质形成的影响,并从同化物的积累与转运、碳氮代谢关键酶活性、内源激素以及分子机理等方面综述了其生物学机制;讨论了减轻水稻高温危害的关键技术措施和水稻响应高温胁迫机制的重点研究方向,为水稻抗高温育种和栽培提供一定的理论依据。

Abstract:

High temperature stress is the main environmental factor that threatens grain yield and quality of rice. This paper summarized the effects of high temperature stress on grain-filling and rice quality formation, and reviewed its biological mechanism from the aspects of assimilates accumulation and transport, activities of key enzyme involved carbon and nitrogen metabolism, endogenous hormones and molecular mechanism, and discussed the key technical measures to alleviate the high temperature damage on rice and considerable suggestions for future study. The review may provide insights for guiding cultivation and breeding of thermo-tolerance rice.

Key words: rice, high temperature stress, grain filling, rice quality, physiological mechanism
