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...

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...

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...

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,...

Genetic variation and mating system of ponderosa pine in the Willamette Valley of Oregon

Creator:: Gooding, Geoffrey David
Abstract:: The population genetic structure of ponderosa pine (Pinus ponderosa Dougi.) in the Willamette Valley of Oregon was investigated. Cones were collected from native stands of ponderosa pine from the Willamette Valley, eastern Oregon, southwest Oregon and the Puget Sound Basin of Washington. Seeds were subjected to isozyme analysis of 12...

Classification strategies for unbalanced binary maps : finding Ponderosa pine in the Willamette Valley

Creator:: Riddell, Audrey P.
Abstract:: Forest species classifications are becoming increasingly automated as advances are made in machine learning. The algorithms used to identify tree species range from simple decision trees to intricate neural networks, and often excel in accurately delineating tree species. However, complex algorithms can have high input costs, including the cost of...

Stress response as a basis for disease susceptibility in Ponderosa Pine

Creator:: Koonce, Andrea
Abstract:: Trees stressed by artificial and natural means were sampled for response in growth and vigor, carbohydrate content, resin pressure characteristics, and water relations. Tree response was found to reflect both the severity and type of stress imposed. Crown color and appearance were reliable indicators of prolonged stress and advanced decline...

The expression of functional traits during seedling establishment in two populations of Pinus ponderosa from contrasting climates

Creator:: Kerr, Kelly L.
Abstract:: Vegetation patterns and species distributions are strongly linked to soil moisture regimes, and populations within a species from contrasting climatic regimes could exhibit differences in the degree to which certain functional traits related to establishment are expressed. Tree seedling survival is crucial for forest regeneration, and thus may be a...

The Past, Present, and Future of Fire and Ponderosa Pine Stand Dynamics in the Metolius Research Natural Area, Central Oregon

Creator:: Johnston, Kayla M.
Abstract:: The Metolius Research Natural Area (RNA), located 29 km northwest of Sisters, Oregon, was originally established in 1931 to maintain a ponderosa pine (Pinus ponderosa Dougl. Ex Laws) and dry, mixed-conifer forest with the aim to meet objectives of preserving natural conditions, providing for research opportunities, and preserving gene pools...
