Abstract: Methyl jasmonate as a phytohormone and signal molecule related to anti-injury can stimulate the expression of plant defense gene and induce the protective effect similar to mechanical injury. During the storage and transportation,the contents of antioxidant substance such as total phenol,ascorbic acid and glutathione decreased,as a result,its antioxidant activity is reduced,and quality and resistance are adversely affected,ultimately shortening the shelf life of fruits and vegetables,resulting in a certain economic losses. It is found that methyl jasmonate enhances the resistance of fruits and vegetables,effectively maintains the antioxidant activity of fruits and vegetables,reduces the loss of quality,and prolongs the shelf life by increasing the activity of synthetic enzymes and antioxidant-related enzymes in fruits and vegetables. This paper reviews the research progress of methyl jasmonate in fruits and vegetables application in recent years,focus on the effects of methyl jasmonate on the resistance,antioxidant activity and quality of fruits and vegetables and its mechanism. It provides reference for the research and application of methyl jasmonate in fruits and vegetables preservation in the future.
