摘　　要：钾作为植物生长所必需的三大营养元素之一,对植物的生长发育具有重要作用.低钾胁迫对植物产量和品质有显著的不利影响.概述了低钾条件下植物生理响应的机制及钾通道和钾转运体的功能,并简述了甘薯耐低钾基因研究进展及进一步提高钾利用率的研究方向.Potassium,as one of the three essential nutrients for plant growth,plays an important role in plant growth and development.Potassium deficiency stress has a great negative impact on plant yield and quality.In this paper,the mechanism of plant physiological response and the functions of potassium channels and potassium transporters under low potassium condition are summarized,and the research progresses of low potassium tolerance gene in sweetpotato and further research directions of improving the potassium utilization ratio are also briefly described.

关 键 词：低钾 生理机制 钾通道 钾转运体 甘薯
