Other claims from this paper (8)
- Association Magnitude and rate of soil water deficit development influenced carrot responses.
- Method / resource Stomatal conductance and leaf water potential were the most sensitive and consistent water-status indicators.
- Intervention effect Low-frequency continuous-deficit irrigation moderately reduced stomatal conductance.
- Intervention effect Low-frequency continuous-deficit irrigation greatly reduced peak leaf area.
- Intervention effect Low-frequency continuous-deficit irrigation maintained viable late-season leaf area.
- Mechanism These water-conserving responses allowed reduced-rate growth and viable seed development.
- Intervention effect Rapid deficit development stopped growth.
- Intervention effect Rapid deficit development rapidly reduced leaf area.
