Micropropagation of Douglas fir (Pseudotsuga menziesii) in a double-phase culture medium

Creator:: Gross, Leah M.
Abstract:: The timber and Christmas tree industries are important components of the Pacific Northwest economy. A goal of both industries is to produce high quality trees with high growth rates. Accomplishing this requires increased genetic quality of the trees grown. Tissue culture provides the most promise for propagating these superior genotypes....

First-year performance of 1-0 containerized Douglas-fir seedlings on droughty sites in southwestern Oregon

Creator:: Hobbs, Stephen D., Oregon State University. Forest Research Laboratory, Byars, R. H ., Henneman, D. C., and Frost, C. R.
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,...

Size and survival of 2-0 Douglas-fir seedlings

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...

Early growth and drought avoidance in Douglas-fir seedlings

Creator:: Heiner, Terry Charles, 1941-, Lavender, Denis P., and Oregon State University. Forest Research Laboratory
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...

Early growth of Douglas-fir in a reciprocal planting

Creator:: Ching, Kim K. and Oregon State University. Forest Research Laboratory
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...

Some guidelines for planting 2-0 Douglas-fir in Oregon : a preliminary report

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

Natural regeneration on staggered settings

Creator:: Lavender, Denis P., Bergman, Morris H., and Calvin, Lyle David, 1923-
Abstract:: In recent years much of the logging in the Douglas fir region has been by the staggered setting system. Consequently, the effects of this system upon natural coniferous regeneration have become increasingly important. This study was designed to analyze the effects of setting size and environmental factors upon natural regeneration...
