摘　　要：褪黑素是广泛存在于动植物体内的小分子吲哚胺类物质,在调控种子萌发、根系发育、果实发育、响应生物和非生物胁迫等过程中发挥着重要作用。近年来,褪黑素也广泛用于园艺果实采后保鲜。介绍了植物褪黑素的合成通路及相关基因,重点综述了褪黑素在调控采后果实衰老、果品品质、低温耐受性、抗菌性等方面的生理功能及作用机理,分析了当前植物褪黑素研究领域中存在的问题,并对未来研究提出了相应的建议,以期为完善植物褪黑素的生理功能和果实采后保鲜技术研发提供参考依据。Melatonin is a type of small molecule indoleamine widely present in both plants and animals,which plays various physiological roles,including regulating seed germination,root development,fruit development,and responding to biotic and abiotic stresses.In recent years,melatonin has also been extensively used in post-harvest preservation of horticultural fruits.This article introduces the synthesis pathways of plant melatonin and the related genes,with a focus on reviewing the physiological functions and mechanisms of melatonin in regulating post-harvest fruit aging,fruit quality,cold tolerance,and antibacterial properties.It analyzes the current issues in the field of plant melatonin research and offers suggestions for future studies,aiming to provide a basis for improving the physiological functions of plant melatonin and the research and development of post-harvest preservation techniques for horticultural fruits.
