Summary

Greenhouse-cultured, container-grown seedlings of interior Douglas fir (Pseudotsuga menziesii var glauca (Beissn) Franco), Engelmann spruce (Picea engelmannii (Parry) Engelm), and ponderosa pine (Pinus ponderosa var scopulorum Engelm), were acclimated and deacclimated to cold in growth chambers over 19 weeks. Heat tolerance and cold hardiness of needles, and bud dormancy, were measured weekly. Results are given.
