作物对干旱胁迫的响应研究进展

Progress on the Crop Response Mechanism to Drought Stress

干旱是一种最为广泛的田间逆境,对作物生长有严重影响,且不同类型作物的不同时期在不同干旱处理下的表现不同。综述干旱胁迫对作物形态结构、光合指标、产量、作物渗透调节物质、活性氧代谢的影响机理及程度,为提高作物产量及发展节水农业提供参考。

Drought is one of the most extensive field adversities, which will have serious effects on crop growth. Crops of different types show different performance under drought treatment and in different period. This article reviews the influence mechanism and extent of drought on crop morphology, photosynthesis, yield, crop osmotic mechanism regulating materials, metabolism of active oxygen substances in a bid to provide reference for the improving crop yield and developing water-saving agriculture.
