Bioprotection of unseasoned Ponderosa pine lumber from microbial discoloration

Creator:: Kreber, Bernhard
Abstract:: The potential of 9 bacterial and 6 fungal isolates to protect wood against wood staining microorganisms was studied using small sapwood samples of unseasoned Ponderosa pine [Pinus ponderosa Laws] sapwood. Bacillus subtilis Cohn, isolate 733 A , Gliocladium virens J.H. Miller, J.E. Giddens & A.A. Foster isolate H 3 and...

Relative low temperature tolerance of lodgepole and ponderosa pine seedlings

Creator:: Berntsen, Carl M.
Abstract:: The hypothesis is explored that lodgepole pine at the seedling emergence period is more resistant to low temperatures than ponderosa pine. Differential tolerance between species to low temperatures is then related to the prevalence of lodgepole pine in frost pocket areas in central Oregon to the exclusion of ponderosa pine....

Fertilization of 2-0 ponderosa pine seedlings in the nursery and field : morphology, physiology, and field performance

Creator:: Gleason, John F.
Abstract:: Two-year-old ponderosa pine (Pinus ponderosa Laws.) from two seed sources were grown at two nurseries. The Fremont seed source was raised at Bend and Stone Nursery; the Ochoco was grown at only the Bend Nursery. The seedlings were fertilized in late September-early October with nitrogen (N) or nitrogen plus potassium...

Physiological relationships between dwarf mistletoe and ponderosa pine

Creator:: McDowell, Larry Leon
Abstract:: A comparative study was made of Pinus ponderosa Laws, and Arceuthobium campylopodum Engelm. f . campylopodum to determine (1) whether or not the parasite or parasitized tissues accumulate abnormal concentrations of minerals, (2) whether or not there was evidence of a blockage of mineral translocation in the phloem because of...

The influence of tree cover and shade pattern upon the distribution of understory plants in ponderosa pine stands of central Oregon

Creator:: Robinson, Andrew Frederick, Jr.
Abstract:: Seven sites of uniform topography and soil were selected within a self perpetuating ponderosa pine forest found on the eastern flank of the central Oregon Cascades. These plots were located along a vegetational gradient caused mainly by an orographic rain shadow. Data gathered included density, frequency, and cover for all...

Interactions between fire and dwarf mistletoe in ponderosa pine

Creator:: Koonce, Andrea Lavender
Abstract:: The effects of dwarf mistletoe on fuel in precommercial ponderosa pine stands: Dwarf mistletoe and healthy stands were sampled by vertical planar intercept and whole tree biomass sampling techniques to measure fuel loading in ground and crown fuels. Differences in size, distribution, and vitality of fuel were shown to depend...

The relationship of non-recovered rodent caches to the natural regeneration of ponderosa pine

Creator:: Saigo, Barbara Woodworth
Abstract:: Studies were conducted within a 12-mile radius of Camp Sherman, Oregon, in the Deschutes National Forest during the spring and summer of 1965 and the spring of 1966, with one follow-up visit in the summer of 1967. The feeding and foraging activities of Eutamias amoenus and Citellus lateralis were observed,...

Geographic variation in central Oregon ponderosa pine (Pinus ponderosa Laws.) : seed germination; seed, wing, and cone morphology; seed color

Creator:: Weber, John C., 1948-
Abstract:: Geographic variation was investigated among 225 locations from five geographically disjunct regions in central Oregon. Characters included: germination speed and uniformity in two test environments differing in stratification period and incubation temperature; weight, three dimensions and three 'angles' of seeds; weight and three dimensions of wings; cone length and scale...
