茉莉酸及其甲酯在农业上的应用研究进展

Application Advances of JA and MeJA in Agriculture

茉莉酸类化合物是广泛存在于植物体内的内源激素,参与植物生长发育众多生理过程的调控,诱导植物对病虫害、非生物胁迫产生防御反应,缓解作物对外界不利环境的胁迫。对茉莉酸及其甲酯在提高作物抗逆性,防御病虫害能力,改善作物品质,以及延长农产品货架期等方面的研究进展进行综述,为绿色农业的发展提供依据。

Jasmonic acid(JA)is a kind of endogenous hormone widely existed in plants.As a signal molecule in plants,it is involved in the regulation of many physiological processes of plant growth and development,induces plant defense response to diseases and insect pests,abiotic stress,activates plant defense genes and alleviates crop stress to the environment.In this paper,the research progress of JA and methyl jasmonate(MeJA)in improving crop resistance,defending against diseases and pests,improving crop quality and extending the shelf life of agricultural products were briefly introduced.
