Arbuscular mycorrhiza fungi (AMFs) are a group of soil-dwelling fungi that form symbiotic associations with plants, to mediate the secondary metabolism and production of active ingredients in aromatic and medicinal plants. Currently, there is little research on Bge. inoculation with native AMFs and the concomitant effects on growth and secondary metabolites. In this study, was treated with eight AMFs, i.e., ; ; ; ; ; ; ; , to investigate the influence of AMF inoculation on biomass and secondary production under greenhouse conditions in roots. The results showed that mycorrhiza formation rates were between 54.83 and 86.10%. Apart from and treatment, the roots biomass of the other treatment groups was effectively increased, and the fresh and dry weight of the plant inoculated with were increased by 86.76 and 86.95%, respectively. Specifically, AMF treatments also impacted on phenolic acids production; inoculation with both or significantly reduced total phenolic acids, whereas the other treatments effectively increased these levels, of which generated significant levels. Most AMF-plant symbiotic experiments facilitated phenolic acid accumulation in the secondary metabolites of (except ). This study showed that most native AMFs inoculation with promoted roots growth and increased secondary metabolites production (especially phenolic acids). Going forward, inoculation of native AMF is a promising method to improve the quality and yield of and should be considered during production.
丛枝菌根真菌（AMFs）是一类生活在土壤中的真菌，它们与植物形成共生关系，以调节芳香植物和药用植物的次生代谢及活性成分的产生。目前，关于用本地AMFs接种白木香以及对其生长和次生代谢产物的伴随影响的研究很少。在本研究中，对白木香进行了8种AMFs接种处理，即[此处8种菌根真菌名称缺失]，以研究在温室条件下AMF接种对白木香根系生物量和次生代谢产物的影响。结果表明，菌根形成率在54.83%至86.10%之间。除[此处两种菌根真菌名称缺失]处理外，其他处理组的根系生物量均有效增加，接种[此处菌根真菌名称缺失]的植株鲜重和干重分别增加了86.76%和86.95%。具体而言，AMF处理也影响了酚酸的产生；接种[此处两种菌根真菌名称缺失]均显著降低了总酚酸含量，而其他处理则有效提高了这些含量，其中[此处菌根真菌名称缺失]产生了显著水平。大多数AMF-植物共生实验促进了白木香次生代谢产物中酚酸的积累（[此处除外的菌根真菌名称缺失]）。本研究表明，大多数本地AMFs接种白木香可促进根系生长并增加次生代谢产物的产生（尤其是酚酸）。展望未来，接种本地AMF是提高白木香品质和产量的一种有前景的方法，在生产过程中应予以考虑。
