丛枝菌根真菌在药用植物上的应用研究进展

为了将农业生态系统中广泛分布的丛枝菌根真菌(AMF)资源科学地应用于药用植物,本文对AMF分类、中国药用植物资源现状及AMF在药用植物上的应用分别进行了总结。AMF不仅能改善药用植物的营养水平,促进其生长;而且能促进药用植物体内萜类、甾体类及黄酮类等活性物质的合成与积累;此外,AMF对药用植物因连作引发的各种土传病虫害也表现出积极的生防作用。因此,AMF在药用植物栽培领域具有极大的应用潜力。同时,鉴于菌根专性共生的特性,提出了扩大与AMF共生的药用植物种类、AMF与其他有益微生物混合接种、共生体建成过程中土壤生态环境变化等尚待探究的问题,以期为该领域的深入研究提供借鉴与参考。

The Application of Arbuscular Mycorrhizal Fungi in Herbs: A Review

In order to scientifically apply the arbuscular mycorrhizal fungi (AMF) resources widely distributed in agroecosystems to herbs, AMF classification, the current status of Chinese herb resources and the application of AMF in herbs were summarized in the paper individually. AMF can not only improve the nutritional level and enhance the growth of herbs, but also promote the synthesis and accumulation of active substances in herbs such as terpenoids, steroids and flavonoids. Moreover, AMF show positive biocontrol effects on various soil borne diseases and pests caused by continuous cropping system of herbs. Therefore, AMF have great application potential in herbs' cultivation. Meanwhile, in view of the obligate symbiosis characteristics of mycorrhizae, some research issues still need to be explored, such as the expansion of the herb species associated with AMF, the mixed inoculation of AMF with other beneficial microorganisms, and the changes in soil ecological environment during the establishment of symbiosis. The study will provide reference for further research in the field.
