Creator:: Koonce, Andrea Lavender
Abstract:: The effects of dwarf mistletoe on fuel in precommercial ponderosa pine stands: Dwarf mistletoe and healthy stands were sampled by vertical planar intercept and whole tree biomass sampling techniques to measure fuel loading in ground and crown fuels. Differences in size, distribution, and vitality of fuel were shown to depend...

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...

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...

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...
