The effect of γ-PGA on the appearance of maize roots, IAA content in roots and rhizosphere soil, and urease activity of rhizosphere soil. A Phenotypes of maize after γ-PGA (10 kDa, 50 mg/L) and L-Glu (50 mg/L) treatment. B The primary root length of maize with γ-PGA, L-Glu treatment, and control maize (CK). C-E The seminal root, crown root and lateral root number of maize with γ-PGA, L-Glu treatment, and control maize (CK). F-H The total seminal root, crown root and total root length of maize with γ-PGA, L-Glu treatment, and control maize (CK). I The fresh weight of maize roots with γ-PGA, L-Glu treatment, and control maize (CK). Values are means ± sd (n = 5 repeats). Significant differences are indicated by different letters (P ≤ 0.01)
