摘要: 茉莉酸甲酯(methyl jasmonate,MeJA)是一种广泛存在于植物中的生长调节因子,具有广谱的生理效应,其作用于果蔬能够显著诱导果蔬产生抗病性、提高果蔬的耐冷能力、改善果蔬采后的感官品质和耐贮性。MeJA改善果蔬采后品质的机制主要包括诱导基因的表达、提高抗氧化及抗病相关酶的活性、促进抗性物质的积累、改善果蔬体内能量的代谢等方面。本文就MeJA的结构及理化性质、在果蔬采后方面的应用现状、作用机制及其在果蔬生产中的作用方式进行了综述,并讨论了其研究和应用前景,以期为MeJA在果蔬采后中的深入研究及推广应用提供参考。

Abstract: Methyl jasmonate (MeJA) is a growth regulator ubiquitously found in plants, which has a wide range of physiological functions. MeJA can significantly induce disease resistance, improve chilling tolerance, maintain the postharvest quality and prolong the storage period of fruits and vegetables. The mechanism of action of MeJA in improving the postharvest quality of fruits and vegetables mainly include inducing gene expression, increasing the antioxidant and disease resistance-related enzyme activities, promoting the accumulation of disease resistant-related substances, and improving energy metabolism. In this article, the structure and physicochemical properties of MeJA are described and the current status of the application of MeJA to postharvest fruits and vegetables as well as its mechanism of action and application modes (alone or in combination with other treatments) is reviewed. In addition, future research and application prospects are also discussed. We expect that this review can provide valuable information for further studies on the application of MeJA in postharvest fruits and vegetables.
