摘　　要：褪黑素是广泛存在于果蔬体内的一种吲哚胺类化合物,具有调控果蔬成熟与衰老、清除活性氧自由基、增强果蔬生物和非生物胁迫抗性的作用,被认为是一种天然、高效、安全的果蔬保鲜剂。研究表明,褪黑素在降低采后果蔬冷害方面具有显著调控作用。该文主要从褪黑素处理对采后果蔬细胞膜结构和功能、抗氧化系统、能量代谢、脯氨酸代谢、糖代谢等方面的调控作用减轻采后果蔬冷害机制进行综述,并对影响褪黑素减轻果蔬冷害的因素进行了分析,以期为褪黑素控制采后果蔬冷害提供参考依据。Melatonin is a kind of indole amine tryptamine compound widely existing in fruits and vegetables,which has physiological effects such as regulating fruits and vegetables ripening and senescence,scavenging reactive oxygen species,and enhancing biotic and abiotic stress resistance.It is a natural,efficient,and safe fresh-keeping agent for fruits and vegetables.Studies demonstrate that melatonin plays a significant regulatory role in reducing the chilling injury of postharvest fruits and vegetables.In this paper,the mechanisms of melatonin treatment to reduce chilling injury of postharvest fruits and vegetables were reviewed in detail from the aspects of cell membrane structure and function,antioxidant system,energy metabolism,proline metabolism,and sugar metabolism,and the factors influencing melatonin treatment to alleviate postharvest fruit and vegetable chilling injury were discussed,which could provide a reference for the application of melatonin in the control of chilling injury of postharvest fruits and vegetables.
