摘要
茉莉酸甲酯(Me JA)是环戊酮衍生物之一,茉莉酸甲酯作为植物体内一类信号物质,在植物的生长发育、应激反应和次生代谢过程中发挥类似激素的作用,对植物的生长发育和防御系统都具有一定影响。本论文通过对茉莉酸甲酯对采后果蔬品质控制中的应用进行综述。茉莉酸甲酯(Me JA)通过诱导果蔬产生并提高细胞壁水解酶(如几丁质酶、β-1,3-葡聚糖酶)和抗性物质合成酶(如苯丙氨酸解氨酶、过氧化物酶和多酚氧化酶)的活性,从而增强果蔬对机械损伤和病原侵染的抗性。同时,茉莉酸甲酯还能能够诱导植物防御基因的表达,诱导果蔬产生一系列具有防御功能的次生代谢物质(如花青素等)来改善果蔬保鲜品质。
Methyl jasmonate is one of cyclopentanone derivatives. It is a kind of signal substance that plays important hormonal-like roles in the regulation of plant development and defensive system. Quality controlling of post-harvest fruits and vegetables induced by methyl jasmonate (MeJA) has been reviewed. The MeJA improved resistance to disease in fruits and vegetables by improving the content of the activities of cell wall hydrolase (including chintinase andβ-1,3-glucanase) and resistant enzyme (including phenylalanine ammonia-lyase, peroxidase and polyphenol oxidase). These studies on resistant qualities mechanism of mechanical wound and disease induced by the MeJA will provide references for the application of biological technology qualities controlling in fruits and vegetables by inducing the secondary substance (eg. anthocyanins).
