摘　　要：马铃薯作为世界四大粮食作物之一,对于保障粮食供应和安全具有重要的意义。干旱胁迫制约了马铃薯生产,严重影响其经济效益。然而,目前对马铃薯的抗旱性机制缺乏系统性的研究。综述对近年来马铃薯抗旱方面的研究进行了系统的总结,包括对农艺性状影响、代谢物质的变化、光合作用的影响及马铃薯抗旱分子机制4个方面,为后续马铃薯抗旱机制的研究和选育高产抗逆、高品质的马铃薯品种提供重要参考。As one of the four major food crops in the world, potato plays an important role in ensuring food supply and security. Drought stress limits potato output and has a negative impact on its economic benefits. However, at present, there is a lack of systematic research on the mechanism of drought tolerance in potato. This review systematically summarized the research on drought tolerance of potato in recent years, which includes four aspects: the impacts of drought on agronomic characters, the changes of metabolite caused by drought, the impacts of drought on photosynthesis, and the molecular basis of potato drought tolerance. This review would be a valuable reference for future researches on potato drought tolerance mechanisms and the selection of high-yielding, stress-tolerant, and highquality potato cultivars.
