Table 1 Effect of γ-PGA on the contents of ABA and Urease activity of maize rhizospheric soil under severe drought stress
Drought | ABA (μg/g DW) | Urease activity (μg NH3-N/g/24 h) |
|---|---|---|
0 mg/L γ-PGA | 1.479 ± 0.011 | 767.583 ± 124.714 |
50 mg/L γ-PGA | 1.800 ± 0.002** | 980.524 ± 46.475** |
