Other claims from this paper (6)
- Association Pecan budbreak depended jointly on heating and chilling.
- Observation Pecan budbreak could occur without chilling after sufficient heat accumulation.
- Association Pecan budbreak variability increased sharply below about 100 chilling degree days.
- Observation Heating degree days with daily minima below 2.2C were inefficient.
- Method / resource A 3.9C base was most efficient for heating and chilling.
- Method / resource The stated regression predicted heat days for budbreak from chill days across a broad geographic range.
