Data represent mean values of five biological replicates. Standard error of the means is indicated in parentheses. Different letters indicate significant differences at p < 0.05 according to Tukey’s HSD. M = percentage of root length colonized by AMF; m = mycorrhization intensity of mycorrhizal root fragments; TRL = total root length; SRL = specific root length; RD = root diameter; FRL = fine root length; and RHL: root hair length.
