AMF colonization and root vigor of C. migao seedlings at different growth stages.
CK, no inoculation; C. etunicatum, seedlings inoculated with C. etunicatum; F. mosseae, seedlings inoculated with F. mosseae; and Mixed, seedlings inoculated with C. etunicatum and F. mosseae. PS: prior stress, SS: subjected to drought stress; REC: rewatered; DS: drought stress. Different letters (a, b, c, d) indicate a significant difference by Tukey’s post hoc test. ns, not significant; * P < 0.05 and ** P < 0.01. Values are expressed as the SE (n = 5, which are treatment replicates).
