Correlations of leaf γ-aminobutyric acid (GABA) concentration with stomatal conductance (gs, A) and malic acid (MA, B) concentration of maize plants inoculated with (AM) and without (NM) Arbuscular mycorrhizal fungus under drought stress. The Pearson correlation coefficient (r) and linear regression analysis (P < 0.05) were used
