- Intervention effect Above-deficiency nitrate decreased stomatal conductance in maize growing in drying substrate.
- Intervention effect Above-deficiency nitrate decreased maize leaf growth rate in drying substrate.
- Intervention effect Xylem KNO3 above 2.0 mol m-3 reduced transpiration in detached maize shoots.
- Intervention effect Xylem KNO3 above 12 mol m-3 reduced maize leaf growth rate.
- Mechanism Nitrate effects on transpiration and growth were attributed to pH-based ABA redistribution.
- Intervention effect ABA at 0.05 mol m-3 sensitized maize leaf growth to KNO3 increases from 3.0 mol m-3.
- Intervention effect KNO3 enhanced the growth-reducing capacity of higher ABA concentrations.
- Intervention effect ABA reduced maize transpiration.
- Intervention effect Buffers at pH 6.7-7.0 reduced transpiration relative to pH 5.0.
- Intervention effect KNO3 and ABA synergistically reduced maize transpiration.
- Intervention effect KNO3 and high-pH buffer showed a synergistic effect on transpiration.
- Intervention effect pH 5.6 buffer alleviated transpiration depression from 12 mol m-3 KNO3.
- Intervention effect pH 6.7 buffer increased growth sensitivity to KNO3.
- Observation Xylem sap nitrogen initially increased during soil drying, then decreased at lower water potentials.
