茉莉酸甲酯在鲜果生产中应用的研究进展

Research Progress in Application of Methyl jasmonate in Fresh Fruit Production

茉莉酸甲酯(Methyl jasmonate,MeJA)是一种广泛存在于植物中的内生激素,能够调控多种代谢途径,诱导防御基因的表达以提升其抗病、抗虫及抗冷能力,提高抗氧化相关酶的活性,延缓采后鲜果的衰老进程,改善采后鲜果的感官品质及耐贮性,促进色素和香气物质积累。该文总结了茉莉酸甲酯在鲜果抗逆性、鲜果品质、采后品质等方面的积极作用及作用机制,以期为茉莉酸甲酯在鲜果中的推广应用及深入研究提供理论参考。

Methyl jasmonate(MeJA)is an endogenous hormone widely existing in plants,which can regulate multiple metabolic pathways.MeJA can induce the expression of defense genes to improve its resistance to disease,insect and cold,improve the activity of antioxidant enzymes to delay the aging process of post-harvest fresh fruit,improve the sensory quality and storage of post-harvest fresh fruit,promote the accumulation of pigment and aroma substances.This article summarizes the positive effects and mechanisms of MeJA in the stress resistance of fresh fruit,fruit quality and post-harvest quality of fresh fruit,in order to provide theoretical reference for the application and in-depth research of MeJA in fresh fruit.
