Creator:: Wright, Ernest and Oregon State University. Forest Research Laboratory
Abstract:: Correlation was sought between abundance of mycorrhizae on Douglas-fir seedlings and their survival in field plantations. One possible indication of dormancy desirable for lifting from nursery beds could be the varying seasonal abundance of ectotrophic mycorrhizae on roots of seedlings. No direct correlation between percentage of mycorrhizae and survival in...

Abstract:: Survival and growth during three years at 8 out-planting areas are reported for Douglas-fir from 14 sources of seed. Early survival was highest near Nimpkish on Vancouver Island. At most plantations, trees from the local seed source grew as well as did those from the best three sources. Trees from...

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...

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:: Although the Douglas-fir region of the northwestern United States and British Columbia is frequently considered to have a common silviculture, obstacles to successful regeneration of the species range from competing vegetation and mammals on the mesic sites to extreme drought and heat on the xeric southerly exposures in northern California...

Creator:: Zaerr, Joe B., Lavender, Denis P., and Oregon State University. Forest Research Laboratory
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...

Abstract:: The effects of artificial shading and aspect on the performance of 1-0 container-grown Douglas-fir seedlings were evaluated 1 year after outplanting on four different aspects in southwest Oregon. The test areas, all characterized by steep slopes and shallow, skeletal soils with a surface mantle of loose rock and logging slash,...
