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...

Reduction in growth of pole-sized Ponderosa pine related to a Pandora moth outbreak in central Oregon

Creator:: Cochran, P. H.
Abstract:: A pandora moth (Coloradia pandora Blake) outbreak began in 1991 in a ponderosa pine (Pinus ponderosa Dougl. ex. Laws) spacing study area that also included scattered sugar pine (P. lambertiana Dougl). The relation of defoliation to five tree spacings (with and without understory vegetation) was examined, and stand growth reduction...

Effects of fall lifting and long-term freezer storage on ponderosa pine seedling physiology and quality

Creator:: Omi, Steven Katsu
Abstract:: Two-year-old ponderosa pine (Pinus ponderosa Dougl. ex Laws.) seedlings from two Oregon seed sources were lifted three times in the fall, stored below freezing (-1.5°C), and compared to seedlings that were handled conventionally (spring lifting followed by short-term cold storage, 2-4°C). Based on patterns of budbreak in a greenhouse and...

Fungitoxicities of NaMDC decomposition products to decay fungi colonizing Doulgas-fir and ponderosa pine wood

Creator:: Canessa, Edwin
Abstract:: Metham sodium or NaMDC is one of the four major soil fumigants that are currently registered for controlling internal decay of wood products in use. Fumigants are used primarily in utility poles but are also applied to piling, timbers and other large wood members. NaMDC must decompose to fungitoxic compounds...

Long-term effects of prescribed fire on nitrogen availability in ponderosa pine stands in central Oregon

Creator:: Monleon-Moscardo, Vicente J.
Abstract:: The effects of prescribed burning on the rates of recent litter decomposition, nitrogen and phosphorus release from litter, soil total and inorganic nitrogen pools, and net nitrogen mineralization were determined in ponderosa pine sites that had been burned 0.3, 5 or 12 years earlier. Prescribed burning decreased litter decomposition rates...

The influence of antidesiccants on field performance and physiology of 2+0 ponderosa pine (Pinus ponderosa Dougl.) seedlings

Creator:: Vera-Castillo, J. A. Gil
Abstract:: This thesis research examines the effects of film-forming antidesiccants applied to dormant pondexosa pine (Pinus ponderosa Dougl.) seedlings after being lifted and to actively growing seedlings. The basic proposition was that antidesiccants would have a positive effect on reducing water loss in ponderosa pine seedlings. In order to evaluate the...

Height-diameter and volume equations, growth intercept and needle length site quality indicators, and yield equations for young ponderosa pine plantations in Neuquén, Patagonia, Argentina

Creator:: Gonda, Hector Eduardo
Abstract:: Ponderosa pine (Pinus ponderosa Dougl. ex Laws.) is the most widely planted species in the Patagonian Andes region of Argentina for economic development. However, information on site quality and yield is so limited that potential forest investors and managers do not have a reliable basis on which to make sound...

Response of ponderosa pine forests in central Oregon to prescribed underburning

Creator:: Landsberg, Johanna Dobrot
Abstract:: Tree growth and soil nutrient responses to prescribed underburning were determined for a period of up to 12 years at four sites in northcentral and central Oregon ponderosa pine stands (Pinus ponderosa Dougl. ex Laws). Differences reported are significant at a = 0.10. During the first 4-growing-season-measurement period after underburning,...

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...

An analysis of peripheral milling of finger-joints in ponderosa pine cut-stock

Creator:: Liu, Yongsheng
Abstract:: To make low grade lumber into high-valued products, finger-jointing is a widely used method in the timber industry. In certain situations, chip-out occurs degrading the quality of the joint. To better understand the machining process, a beam-type dynamometer based on strain gages was designed to analyze the dynamic cutting forces...
