Other claims from this paper (7)
- Method / resource A 10-min or longer equilibration period was suitable for accurate stem water potential measurements.
- Method / resource About 10 leaves with 10-min equilibration reduced time-related SWP measurement error to 0.05 MPa.
- Recommendation More variable orchards may need a larger sample.
- Observation Midmorning and midday SWP showed similar seasonal patterns and irrigation responses.
- Method / resource Midday SWP was sometimes accurately predicted from midmorning SWP and VPD change.
- Method / resource Prediction errors up to 0.3 MPa occurred with unusual VPD changes.
- Recommendation Direct midday SWP measurement remains recommended.
