Effects of AMF on low-molecular-weight organic acid concentrations secreted by maize roots. (A): the concentration of oxalic acid secreted by maize roots with and without AMF inoculation; (B): the concentration of tartaric acid secreted by maize roots with and without AMF inoculation; (C): the concentration of malic acid secreted by maize roots with and without AMF inoculation; (D): the concentration of citric acid secreted by maize roots with and without AMF inoculation; (E): the concentration of succinic acid secreted by maize roots with and without AMF inoculation. The different lowercase letters indicate significant differences among treatments; “**” mean p < 0.01 according to two-way ANOVA.
