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.
