Strobilus production and growth of Pacific yew under a range of overstory conditions in western Oregon

Creator:: DeFazio, S. P., Vance, N. C., and Wilson, M. V.
Abstract:: Strobilus production, growth, and morphology of Pacific yew (Taxus brevifolia Nutt.) were examined at three sites in the Cascade Mountains and one site in the Willamette Valley of western Oregon. Strobilus production on branch segments was positively associated with overstory openness for male and female trees at all four sites...

Seedborne Phytophthora infestans : effect of pathogen clonal lineage and potato cultivar on seed transmission of late blight and plant growth responses

Creator:: Partipilo, Heather M.
Abstract:: Seed piece to plant transmission of the potato late blight pathogen, Phytophthora infestans, occurred with isolates of the clonal lineages US-8 in Oregon and US-11 in Washington in field trials. Average transmission rate across potato cultivars was 0.5 and 2.4% with US-8, and 0.8 and 1.0% with US-11 in 1999...

Susceptibility of coast redwood seedlings to Phytophthora ramorum

Creator:: Lucas, Sunny L.
Abstract:: Coast redwood (Sequoia sempervirens) (D. Don) Endl. is a host for Phytophthora ramorum but it was unclear if the pathogen represents a significant disease risk to this tree species. In this study the susceptibility of coast redwood seedlings and the likelihood of sporulation on redwood were examined. Two methods were...

Systematic and reproductive studies of Mimulus (Scrophulariaceae) in the Pacific Northwest : implications for conservation biology

Creator:: Meinke, Robert James
Abstract:: The Mimulus washingtonensis complex is a group of morphologically similar species centered in the Pacific Northwest. All are rare, and most are under consideration for listing as endangered. Morphometric and pollination data were used in developing a revised taxonomy for the group. Five species and two varieties are recognized. Mimulus...

Environmental factors influencing the rate of spread of Phellinus weirii (Murr.) Gilbertson in young-growth Douglas-fir

Creator:: Angwin, Peter A.
Abstract:: Studies to identify the environmental factors that influence the rate of ectotrophic mycelial growth of Phellinus weirii (Murr.) Gilbertson along Douglas-fir roots were undertaken both in the laboratory and in the field. The effects of soil pH, nitrogen, moisture, temperature, microorganisms and bulk density were investigated. In the lab, the...

Response of the nitrogen-fixing lichen Lobaria pulmonaria to phosphorus, molybdenum, and vanadium

Creator:: Marks, Jade A., Pett-Ridge, Julie C., Perakis, Steven S., Allen, Jessica L., and McCune, Bruce
Abstract:: Nitrogen-fixing lichens (cyanolichens) are an important source of nitrogen (N) in Pacific Northwest forests, but limitation of lichen growth by elements essential for N fixation is poorly understood. To investigate how nutrient limitation may affect cyanolichen growth rates, we fertilized a tripartite cyanobacterial lichen (Lobaria pulmonaria) and a green algal...

Factors influencing the production and survival of inoculum of Elytroderma deformans

Creator:: Laird, Peter Paul
Abstract:: This study concerns factors affecting production and survival of ascospores of Elytroderma deformans (Weir) Darker, a needle cast of ponderosa pine (Pinus ponderosa Laws.). The results show that summer cooling and a reduction in host vigor delays and diminishes the number of fertile hysterothecia produced. Evidence is offered for classification...
