A pot experiment was conducted to investigate the effects of 27 exogenous arbuscular mycorrhizal (AM) fungi strains on the root mycorrhiza infection rate, physiological and biochemical characteristics, root biomass and terpenoids accumulation of Aucklandia lappa seedlings at room temperature. A. lappa had a good symbiotic relationship with AM fungi, but there was difference in the preference of 27 exogenous AM fungi species for A. lappa. Compared with CK, some AM fungi increased the soluble protein and soluble sugar content and antioxidant enzyme activity in the leaves of A. lappa, reduced the malondialdehyde content, enhanced the ability of A. lappa to resist adverse environment. Biomass of the roots of A. lappa increased significantly in some AM fungal treatment groups. In most AM fungi treatment groups, the content of costunolide, dehydrocostus lactone and total lactones in the roots of A. lappa increased significantly (P<0.05), while some AM fungi treatment groups showed no significant difference or decrease. According to the comprehensive inoculation effect, Gigaspora decipiens, Scutellospora calospora, Racocetra coralloidea, Septoglomus deserticola, Entrophospora colombiana, Paraglomus brasilianum are the potential strains to inoculate A. lappa seedlings under artificial cultivation conditions, which could help to improve the yield and quality of A. lappa.

Key words: Aucklandia lappa, arbuscular mycorrhizal fungi, inoculation effect, physiological and biochemical characteristics, terpenoids, symbiotic preference
