Some Effects of Cold Storage on Seedling Physiology
When tree seedlings are lifted from the nursery in winter and placed into cold storage, they are no longer exposed to the natural environmental factors that provide energy for growth and information for phenological development. This affects many important physiological variables that influence seedling quality. This paper summarizes several years of storage physiology research on Douglas-fir (Pseudotsuga menziesii (Mirb.) Franco). Stored carbohydrates are depleted, dormancy release is slowed, and cold hardiness is gradually lost in cold storage. Root growth potential may increase, decrease, or remain constant, depending on lift date, storage duration, and species. Effects of cold storage on seedling water relations have not been adequately investigated. Tree Planters' Notes 38(2):11-15; 1987.
