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...

Distribution and variation of Armillariella mellea clones in relation to vegetative cover and severity of root rot in Ponderosa pine

Creator:: Cooley, Sally Joan
Abstract:: Root rot due to Armillariella mellea (Vahl. ex Fr.) Karst. is unusually severe in ponderosa pine near Glenwood, Washington. Isolate relations, clonal variability, vegetation patterns, and climate were examined in relation to severity of disease in this area. Ninety-one isolates from 70 infection centers were examined. Pairings of neighboring isolates...

Parasites and predators of Dendroctonus ponderosae Hopkins (Coleoptera : Scolytidae) in ponderosa pine

Creator:: Billings, Ronald F.
Abstract:: The bark beetle Dendroctonus ponderosae Hopkins (Coleoptera: Scolytidae) has caused severe mortality in recent decades to young stands of ponderosa pine in the western United States. Insect parasites and predators, believed to be of importance in the population dynamics of the beetle, were the subject of the thesis research, conducted...

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...

Detection of dwarf mistletoe in young-growth ponderosa pine from color aerial photography

Creator:: Hann, David W.
Abstract:: The purpose of this study was to determine if infection levels of dwarf mistletoe on ponderosa pine could be detected with color aerial photography. The photography was taken in early September using Kodak Ektachrome Infrared Aero and Ektachrome Aero films at scales of 1/4000, 1/2000, and 1/1000. Ground truth consisted...

The role of lytic enzymes in biocontrol of sapstain fungi

Creator:: Liu, Jiajian
Abstract:: The biocontrol potential of Trichoderma harzianum strains B-2A, B-8A, B-4B, B-15B, and B-41 and Serratia plymuthica was evaluated using agar plates and wood wafers of unseasoned ponderosa pine (Pinus ponderosa laws). All five isolates of Trichoderma harzianum and Serratia plymuthica could inhibit stain fungi growth in agar plates and exhibited...

Effects of environment and genetics on western pine shoot borer, Eucosma sonomana, infestation levels in ponderosa pine plantations of central Oregon

Creator:: Prueitt, Sara C.
Abstract:: Infestations of the western pine shoot borer (Eucosma sonomana Kearfott) in young stands of ponderosa pine (Pinusponderosa Lawson), were surveyed on the Deschutes National Forest. Elevation, slope, aspect, tree height, tree diameter, number of shoots in the terminal whorl, stand density, stand age and plant association for each stand were...

Effect of site and silvicultural treatment on insect pests and diseases of young ponderosa pine

Creator:: Norlander, Daniel W. D.
Abstract:: Ponderosa pine is an important species both commercially and ecologically in western North America. This study considers the incidence of insect and disease pests on a series of replicated ponderosa pine research plantations in northern California. The studies, on an environmental gradient, contain a series of silvicultural treatments including vegetation...

Pine butterfly (Neophasia menapia) outbreak in the Malheur National Forest, Blue Mountains, Oregon : examining patterns of defoliation

Creator:: DeMarco, Ariadne T.
Abstract:: The pine butterfly (Neophasia menapia C. Felder & R. Felder) (Lepidoptera: Pieridae) is a relatively host-specific defoliator of ponderosa pine (Pinus ponderosa Dougl. ex Laws). From 2008 to 2012, the Malheur National Forest was subject to an outbreak of pine butterfly in ponderosa pine, peaking at ~100,000 ha of forest...
