Phenotypes of maize supplemented with 50 mg/L γ-PGA under drought stress, and the determination of related physiological indices. A Phenotypes of maize supplemented with 50 mg/L γ-PGA under drought stress. B The determination of related physiological indexes (contents of ABA, soluble sugar, proline, and chlorophyll; and the net photosynthetic rate stomatal conductance) after drought for 5 days, Values are means ± sd (n = 3 repeats for determination of the contents of ABA, soluble sugar, proline, and chlorophyll, and n = 5 repeats for determination of the net photosynthetic rate and stomatal conductance); C The dry weight and the surviving rate after drought stress for 7 days. Values are means ± sd (n = 5 repeats). Significant differences are indicated by asterisks (**, P ≤ 0.01)
