Chemical applications for control of armillaria root rot of Ponderosa pine

Creator:: Filip, Gregory M.
Abstract:: Root rot caused by Armillariella mellea creates roughly circular disease centers of infected dead and dying trees in the younggrowth ponderosa pine forest under study. Research objectives concerning chemical control of the disease were: 1) to test the effectiveness of certain chemicals in protecting living pines adjacent to disease centers...

Infection of stressed ponderosa pines by Armillariella mellea from indigenous and artificial inoculum sources

Creator:: Fuller, Lloyd Randolph
Abstract:: Armillariella mellea (Vahl. ex Fr. ) Karst. was grown aseptically in hazel stems (Corylus cornuta var. californica) which were used in the forest to infect 290 ponderosa pines (Pinus ponderosa Laws.) which had been "stressed" in five different manners plus two control groups. All trees were inoculated twice giving a...

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...

Silviculture of central and southern Rocky Mountain forests : a summary of the status of our knowledge by timber types

Creator:: Alexander, Robert R. and Rocky Mountain Forest and Range Experiment Station (Fort Collins, Colo.)
Abstract:: Summarizes a series of comprehensive reports on the silviculture of lodgepole pine, ponderosa pine, mixed conifer, and spruce-fir timber types. Includes what is known, what can be recommended, and what additional information is needed for each timber type. Oxford: 614. Keywords: Silviculture; forest regeneration; growth-yield; Abies lasiocarpa, A. lasiocarpa var....

The effect of plant moisture stress on the physiology and establishment of planted Douglas-fir and ponderosa pine seedlings

Creator:: Cleary, Brian D.
Abstract:: The role of moisture stress in seedling physiology and establishment was studied in both the field environment and laboratory experiments. Plant moisture stress was measured using the pressure chamber technique. This technique was modified and tested using a fascicle of pine needles as a sample, an improvement which allows the...

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...
