THE UTAH CHILL UNIT/FLOWER BUD PHENOLOGY MODELS FOR DECIDUOUS FRUIT: THEIR IMPLICATION FOR PRODUCTION IN SUBTROPICAL AREAS |
| Authors: | J.L. Anderson, E.A. Richardson |
| Abstract:
The chill unit and ASYMCUR models have been developed to predict the phenological development of deciduous fruit trees. When combined with the probabilities for winter injury or late spring freeze damage, developed from long-term temperature records, they effectively predict the likelihood of temperature adversely influencing fruit production. The models will also predict the likelihood of incomplete chilling in deciduous fruit grown in climatic areas that are marginal for the cultivar. | |
