小麦抗旱机理研究进展

Progress in Studies on Drought Resistance Mechanisms in Wheats

干旱是影响小麦产量和品质的重要环境因素,而小麦在干旱胁迫下的抗旱机理非常复杂,不同程度以及不同发育时期的干旱胁迫对不同品种的影响各异。对近年来有关干旱胁迫下小麦的形态结构与渗透调节物质的变化,特别是基因和蛋白表达量的改变进行了综述,对小麦在干旱胁迫下如何提高品质及产量等问题提出建议。

Drought is an important environmental factor affecting wheat yield and quality.There exists considerable genetic diversity among wheat cultivars responsible for various drought stress under different developing stages.In this paper,the recent progress in the studies on ecological characteristics and physical characteristics changes,especially in the genomic and proteomic investigations under drought stress conditions were summarized.Some ideas are suggested for improving wheat yield and quality under drought stress.
