Darrell Sparks Journal of the American Society for Horticultural Science 1993. doi:10.21273/jashs.118.1.29
Other claims from this paper (6)
- Association Pecan budbreak depended jointly on heating and chilling.
- Association Heat required for pecan budbreak decreased as chill accumulation increased.
- Observation Pecan budbreak could occur without chilling after sufficient heat accumulation.
- Association Pecan budbreak variability increased sharply below about 100 chilling degree days.
- 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.
