The influence of atmospheric humidity on three aspects of sporulation of
Sphaerotheca pannosa (Wallr.) Lev. var. rosae Wor., which causes rose powdery
mildew, was studied on leaf disks of susceptible Rosa cultivar Samantha.
To study conidiophore production, leaf disks were inoculated on the adaxial
(upper) surface with conidia of S....
Studies were conducted on pathogenic specialization and
heterothallism in Sphaerotheca pannosa var. rosae, causal agent of
rose powdery mildew.
Methods were developed for isolation and identification of
Sphaerotheca pannosa var. rosae races on rose. Monoconidial isolates were initiated on detached leaves, increased on host plants,
and inoculated to rose cultivars...
Lodgepole pine (Pinus conorta) is a widely distributed forest type across western North America. Central Oregon lodgepole pine forests are ecologically unique when compared to other lodgepole pine ecosystems. Sierra lodgepole pine (Pinus contorta ssp. murrayana) is the dominant variety and often exists as the climax species on pumice soils,...

In This Side of Paradise, The Great Gatsby, and several of his short stories, F. Scott Fitzgerald questions the importance of wealth as a factor in supporting happiness and fostering the American Dream on an individual basis. With these texts, Fitzgerald acknowledges that wealth is a factor and, simultaneously, a...
The influence of atmospheric humidity and free water on germination and germ tube growth of Botrytis cinerea Pers. ex Fr. was studied. Relative humidities (RH) were maintained inside insulated humidity chambers with sulfuric acid solutions of the appropriate concentrations. Insulation was necessary to reduce the incidence of condensation caused by...
The purpose of the study was to: (1) test a client-outcome
evaluation methodology in a community mental health clinic, (2)
relate a measure of clients' recent life change to client outcomes,
(3) relate functions staff perform for clients to staff mental health
profession and to client outcomes, and (4) suggest...
This study explores the use of predictive mapping techniques in developing Landtype Association (LTA) maps for use in natural resource management. These maps are produced for the USDA Forest Service on a regional basis at a 1:100,000 scale. The goal of this study is to develop and test a method...
Elutriation of silica sand particles from a 0.9 X 0.9 m cold
fluidized bed was studied. Data were collected for cases with and
without tubes. During experiments the position of the tube bundle
above the distributor plate and the superficial velocity were varied.
Runs were made at velocities of 0.9...
