- Observation Container-vine transpiration approached 2100 g h -1 and field-vine transpiration approached 2700 g h -1.
- Observation Field-vine transpiration approached 2700 g h -1.
- Method / resource Container-vine gas-exchange and gravimetric instantaneous estimates agreed most closely, with R = 0.96.
- Method / resource Sap flow and gas-exchange transpiration estimates correlated significantly, R = 0.94.
- Method / resource Sap flow and gravimetric transpiration estimates correlated significantly, R = 0.88.
- Method / resource Daily cumulative gas-exchange and gravimetric estimates agreed within 5%.
- Method / resource Daily cumulative sap-gauge estimates agreed within 17% of gas exchange or gravimetry.
- Method / resource Field-vine sap-flow and gas-exchange instantaneous estimates correlated significantly, R = 0.87.
- Observation Field-vine cumulative water use was 18 to 22 L d -1.
- Method / resource Field-vine estimation methods differed by 15% on average.
- Method / resource Sap-flow gauges consistently underestimated high midday transpiration in container and field vines.
- Method / resource The power-control algorithm maintained a 1.5 to 2°C midday surface-temperature difference.
