摘　　要：脱落酸是植物低温逆境下的重要信号因子,在低温胁迫条件下,脱落酸与其受体蛋白的结合能力增强,进而可以感知和传递低温胁迫信号,在对植物体内各物质的平衡调控和对胁迫抗性的诱导等方面起到关键作用。在综述外源脱落酸缓解植物低温胁迫现状的基础上,重点介绍了抗性机制方面的最新研究进展,并对今后的研究方向进行了展望,以期为进一步深入研究外源脱落酸的应用提供借鉴。Abscisic acid（ABA） plays an important role in the response of plants to low temperature and its presence is correlated with the enhancement of chilling resistance in some species. Application of exogenous ABA to chilling plants before, during or even shortly after a low temperature treatment has been shown to protect against chilling injury. Based on the review of current situation in chilling resistance of exogenous ABA, the latest research advances in the chilling resistance mechanisms were summarized and the future work was discussed. This paper would shed light on further studies on chilling resistance mechanisms to exogenous ABA.
