摘要
对近期有关茉莉酸(JA)及其甲酯(Me-JA)影响植物生长、诱导作物的抗病虫能力及提高作物次生代谢物等方面的相关文献进行综述。主要内容包括:1)JA和Me-JA对植物生长有影响,低浓度的Me-JA显著缩短烟草种子的萌发时间,增加鳞茎的数量和鳞叶的鲜质量,促进禾本科植物的颖花开放,而高浓度的Me-JA则具有相反的生理作用;2)JA和Me-JA可以提高植物抵抗病虫危害的能力;3)JA和Me-JA能够促进果实成熟的进程;4)JA和Me-JA可以有效提高药用植物有效成分的含量和丰富种类的多样化。总体看来,茉莉酸及其甲酯在农业生产中的应用前景广阔。
A review was conducted for the application of jasmonate acid （JA） and methyl jasmonate （Me-JA） with focus on their effects on plants growing, pests and disease resistance, and the second metabolites contents. The main findings are as follows： 1） the growth of plants can be affected by JA and Me-JA at different growing stages, e.g., low concentration of Me-JA accelerates the process of tobacco seeds germination, promotes the formation and growth of scales, and enhances the opening of gramineae florets, while higher concentration of Me-JA functions oppositely; 2） the resistances to pests and disease of pants can be enhanced by applying JA and Me-JA; 3）fruits ripening can be speeded up by applying JA and Me- JA; 4） both the content and diversity of bioactive secondary metabolites in medicinal plants can be increased by JA and Me- JA. Generally speaking, the application of JA and Me-JA in agricultural production has wide prospect.
