This bibliography is a continuation of a series formerly prepared by Division 6, Glues and Gluing, of the Forest Products Research Society, and published in the Forest Products Journal. The last such list was published for the year 1963.
Two intermediate cuttings were made in a Douglas-fir (Pseudotsuga menziesii (Mirb.) Franco) stand on the Wilark forest management research area in northwestern Oregon. Age of trees in the stand varied from 47 to 62 years at the first cutting. Crawler tractors were used in both extractions. In the first cutting,...
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...
Germination and survival of Douglas-fir on seedbeds of unburned,
lightly burned, and severely burned soil, charcoal, litter, and sawdust,
exposed to 100, 75, and 25 percent of full light, were studied on a
south-facing clearcutting in the Coast range of Oregon.
Irrespective of exposure to light, germination was best on...
Planting techniques, size and age of seedlings, and protection
against animals were investigated for their influence on survival of
ponderosa pine at two sites in southern Oregon. Caging and mulching
with paper were the most effective measures for reducing mortality.
Preliminary trials prior to large-scale planting were recommended for
determining...
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...
