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...

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...

Fungi on Douglas-fir and ponderosa pine cones from the USDA Forest Service Nursery, Coeur d'Alene, Idaho

Creator:: James, Robert L. and United States. Forest Service. Northern Region
Abstract:: Cones of Douglas-fir and ponderosa pine with extensive mold on external portions of scales were sampled for presence of fungi potentially pathogenic to conifer seedlings in nurseries. The major colonizers of cone scales and external seedcoats for both conifer species were Trichoderma spp. Penicillium spp. were also very common. The...

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...

Extraction of proteins from wood samples colonized by bioprotectants and/or stain fungi

Creator:: Cui, Li
Abstract:: Biological stain (blue stain) reduces wood value and prevents its use in many structural applications. Increasing environmental concerns have restricted the chemicals available for controlling this damage. As a result, biological control has received more interest. The application of these systems to wood has been limited due to their inability...
