Witryna22 lip 2024 · Growing degree-days and photoperiod had a similar importance in terms of predicting intermediate phenological stages (bud swelling and translucent bud scales), whereas growing degree-days were more important than photoperiod for predicting the completion of the bud break process (Tables S10 to S14). Growing degree days (GDD), also called growing degree units (GDUs), are a heuristic tool in phenology. GDD are a measure of heat accumulation used by horticulturists, gardeners, and farmers to predict plant and animal development rates such as the date that a flower will bloom, an insect will emerge from dormancy, or a crop will reach maturity. GDD is credited to be first defined by Reaumur in 1735. biosecurity animals https://prime-source-llc.com
