Chilling and Heating Model for Pecan Budbreak

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.
