Abstract:Models were developed for Douglas-fir (Pseudotsuga menziesii var. glauca (Beissn.) Franco) and grand fir (Abies grandis (Dougl. ex D. Don) Lindl.) to predict shoot growth from degree-days with the logistic growth function. Shoot growth differences were found between these two species. Shoot elongation and western spruce budworm (Choristoneura occidentalis Free.) development were correlated with degree-days above 5.5°C. Forest Sci. 30:743-746.
