小麦是全球最重要的粮食作物之一,高温特别是开花期和灌浆期的高温胁迫严重影响小麦的产量和品质。本文从直接鉴定法和间接鉴定法两个方面提出了小麦耐热性的评价指标;分析了在高温胁迫下温度信号的感知和传递以及植物对高温的响应机理;从传统育种方法和基因工程策略两个方向综述了小麦耐热性培育的研究进展。最后总结了提高小麦耐热性的措施及存在的问题,并提出了今后小麦耐热性研究展望。
Wheat is one of the most important food crops in the word, but the heat stress hazards for wheat production, especially, flowering and grain filling stage of high temperature stress seriously affect the yield and quality of wheat. This article proposed evaluation indicators of wheat heat tolerance from two aspects, namely direct and indirect identification, and analyzed the temperature signal perception and transmission under heat stress as well as plant responsive mechanism to high temperature. In addition, we summarized the research progress of wheat heat tolerance cultivation from the traditional breeding methods and genetic engineering strategies. In the end, we make a conclusion on improvement measures of the wheat heat tolerance and problems, and put forward the future wheat heat tolerance research prospects.
