Relative water content (RWC) of C. migao seedlings under 6 different treatments. Different lowercase letters (x, y, z) in the same d of seedling growth (x-axis) indicate the results of Tukey’s post hoc test (p < 0.05) between treatments. Other different letters (a, b, c, d) indicate significant differences between different stages under the same treatment (p < 0.05). 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).
