Root system and mycorrhizal dependency index (MDI) of C. migao seedlings under 6 different treatments. (a) Taproot length of C. migao seedlings under 6 different treatments, (b) Taproot diameter of C. migao seedlings under 6 different treatments, (c) Number of lateral roots of C. migao seedlings under 6 different treatments, (d) mycorrhizal dependency index of C. migao seedlings under 4 different treatments. Different letters (a, b, c, d) indicate a significant difference of Tukey’s post hoc test (* p < 0.05; ** p < 0.01; ns, not significant) between all treatments. NM, non-AMF plants; G. etunicatum, plants inoculated with G. etunicatum; F. mosseae, plants inoculated with F. mosseae; M-seedling, inoculated by the seedling method; M-seed, inoculated by the seed method. Values are expressed as the mean ± SE (n = 6, which are treatment replicates). * p < 0.05; ** p < 0.01; ns, not significant.
