To review the effects of 1-Methylcyclopropene treatment on the physiology and storage quality of postharvest plum fruits. Effects of 1-MCP treatment on respiration, ethylene production, antioxidant related enzyme activities, hardness and weight loss of postharvest plum fruits were analyzed so as to elaborate the application condition and progress of 1-MCP on fresh-keeping of plum fruits. It showed that 1-MCP could effectively delay the after-ripening of plum fruits, reduce their quality deterioration and have a good control over the occurrence of browning and rotting during storage, which undoubtedly helped to extend their storage time and shelf life. Plum fruits had many varieties and their maturation periods were slightly different. Besides, the effects of 1-MCP treatment differed in different varieties of plum fruits. Therefore, more systematic and in-depth study on the effects of 1-MCP on different varieties of plum fruits and its related mechanism was in great need.
