大豆抗旱生理研究进展

Research Advances in Drought Resistance Physiology of Soybean

大豆是我国主要的粮食作物之一,也是关系国计民生的战略性物资。近年来,受人类活动干扰影响,各地自然灾害频发。其中,干旱的气候条件对大豆的生产造成了极其恶劣的影响。研究表明,大豆抗旱性是一个多基因控制的数量性状,与自然气候条件之间有着错综复杂的关系。基于此,概括了干旱胁迫对大豆生理的影响、面对干旱时大豆做出的响应及抗旱鉴定的生理指标等内容,以期通过对大豆抗旱生理方面的研究,为研究大豆抗旱高产栽培及大豆抗旱育种奠定基础,对提高大豆抗旱性具有重要意义。

Soybean is one of the main food crops in China and also a strategic material related to national economy and people's livelihood.In recent years,affected by human activities,natural disasters occur frequently.Among them,the drought climate condition caused extremely bad influence to soybean production.Studies have shown that soybean drought resistance is a quantitative trait controlled by multiple genes,which has a complex relationship with natural climate conditions.Based on this,the effects of drought stress on soybean physiology,soybean response to drought and physiological indexes of drought resistance identification were summarized,in order to lay a foundation for study on drought resistance and high yield cultivation and drought resistance breeding of soybean,which is of great significance for improving drought resistance of soybean.
