Creator:: Lavender, Denis P. and Oregon State University. Forest Research Laboratory
Abstract:: Perennial woody plants have a complex annual cycle keyed to the environment. Temperate plants have an annual dormant period commonly broken by exposure to low temperatures, although daily photoperiods of 16 hours or longer may partially substitute for the chilling. Shoot growth in the spring is normally stimulated by rising...

Abstract:: One-year-old container-grown Douglas-fir [Pseudotsuga menziesii (Mirb.) Franco] seedlings were outplanted on north, east, south, and west aspects on steep, skeletal Xerochrepts in southwest Oregon. After 2 years, survival rates were highest on north and south aspects, but biomass production (dry weight) was greatest on the west aspect. Shadecards, used to...

Creator:: Lavender, Denis P. and Oregon State University. Forest Research Laboratory
Abstract:: The effect of lifting Douglas-fir seedlings from the nursery bed and replanting them, either immediately or after storage at 2 C for periods up to six weeks, was investigated through a series of experiments conducted in controlled-environment chambers and under field conditions. Seedlings lifted prior to December, or after buds...

Abstract:: This annotated bibliography was compiled to provide a comprehensive list of sources on the ecological factors that affect forest regeneration. Abstracts from 494 publications are indexed by author, species, and subject, and are arranged into 4 major sections. Topics include the effects of biotic factors, abiotic factors, and stand and...

Creator:: Lavender, Denis P., Overton, W. Scott, and Oregon State University. Forest Research Laboratory
Abstract:: The effects of a range of thermoperiods and soil temperatures upon growth of Douglas-fir (Pseudotsuga menziesii (Mirb.) Franco) seedlings were studied. The seeds, of varieties glauca and menziesii, came from eight widely separated areas. Plants from both varieties made maximum growth with soil and air temperatures between 18 and 24...

Abstract:: The Dwight L. Phipps State Forest Nursery at Elkton annually supplies 22 million 2-0 Douglas-fir seedlings to Oregon land managers. Some managers report excellent success in planting, but others report failures, particularly when planting late in the season. In some instances poor survival seemed to be related to storage. Physiological...

Abstract:: Results reported here are from a large study designed to evaluate the effects of certain nursery procedures on subsequent survival of Douglas-fir seedlings. The effects of storage conditions and lifting dates were reported elsewhere (9). The determination of the optimum size of seedling for planting on different sites has been...

Creator:: Hermann, Richard K., Lavender, Denis P., Zaerr, Joe B., and Oregon State University. Forest Research Laboratory
Abstract:: Reforestation sometimes is delayed by planting seedlings that do not have high potential for survival. Several factors influence survival. Unstored Douglas-fir lifted and planted in early fall generally are increasingly harmed by moisture stress the farther south in the Douglas-fir region they are. Such early-lifted seedlings are harmed even more...
