¹³C-CP MAS NMR study of decomposition of five coniferous woody roots from Oregon

Creator:: Hawkins, Robert E.
Abstract:: Using ¹³C cross polarization magic angle spinning nuclear magnetic resonance techniques on 5 species of dead trees from the northwest (western hemlock, Douglas fir, Sitka spruce, lodgepole pine and ponderosa pine) I tracked the lignin and cellulose content over a 22 to 36 year period in order to determine the...

Fungal diversity within decomposing woody conifer roots in Oregon

Creator:: Vandegrift, V. Eleanor
Abstract:: Previous studies have indicated that roots from five tree species (Picea sitchensis, Tsuga heterophylla, Pseudotsuga menziesii, Pinus ponderosa, and Pinus contorta) decompose at different rates across an environmental gradient in Oregon. Measurements of wood chemistry from each tree species as well as moisture and temperature from each location do not...

Impact of Armillaria and annosus root diseases on stand and canopy structure, species diversity, and down woody material in a central Oregon mixed-conifer forest

Creator:: Fields, Kristen L. N.
Abstract:: White and grand fir are both valuable components of the mixed-conifer stand structure managed for late-successional reserves in central Oregon. However, they are often short-lived species because of high susceptibility to root diseases, defoliating insects, bark beetles, and wildfire. This study focuses on the effects of root diseases caused by...

Root rot of sweet corn in western Oregon

Creator:: Oregon State University. Extension Service, Hoinacki, Beth, Powelson, Mary L., and Ludy, Robin
Abstract:: In the past decade, Oregon produced on average 344,000 tons of sweet corn for processing on 43,000 acres annually, which ranked the state fourth nationally. Most Oregon sweet corn is grown in the Willamette Valley where, along with green beans, it is a mainstay of the processed vegetable industry. However,...

Managing insects and diseases of Oregon conifers

Creator:: Shaw, David Carl, 1955-, Oester, Paul T., Filip, Gregory M., and Oregon State University. Extension Service
Abstract:: Discusses options for managing major insect pests and diseases of conifers in Oregon forests: bark beetles, wood borers, and ambrosia beetles; defoliators; aphids, adelgids, and scale insects; terminal and branch insects and pitch moths; root diseases; stem decays; foliage diseases; canker diseases and canker-causing rust diseases; and mistletoes. Extensive references...

Simultaneous equation estimation for individual tree growth in young Southern Oregon and Northern California conifer plantations

Creator:: Hamann, Jeff D.
Abstract:: This thesis presents methods for obtaining asymptotically efficient and consistent parameters and variance estimates for simultaneous equations in a forest growth modelling context. Ordinary Least Squares (OLS), Seemingly Unrelated Regressions (SUR), Two-Stage Least Squares (2SLS) and Three- Stage Least Squares (3SLS) are presented for linear models. The variables, model types...

Serial manure amendments : effects on soil properties and root rot of sweet corn

Creator:: Cox, Bonnie S. Hoffman
Abstract:: The effect of serial (multiple-year) organic matter (OM) amendment on soil properties has been described in some cropping systems, although less is known about the effect of serially amended field soils on soil-borne plant diseases. The objectives of this study were to describe the effects of the third and fourth...

Establishment and growth of natural and planted conifers ten years after overstory thinning and vegetation control in 50-year-old Douglas-fir stands

Creator:: Nabel, Mark R.
Abstract:: Forest managers of public lands in western Oregon and Washington have become increasingly interested in creating additional conifer cohorts in young, even-aged, second-growth Douglas-fir stands. The purpose of our research was to assess the establishment, survival, and growth of naturally-regenerated and underplanted conifers 10-13 years after overstory thinning and understory...

Investigating the Genetic Control of Fusarium Root Rot Resistance in Snap Beans

Creator:: Huster, Abigail R.
Abstract:: Root rot diseases are a major constraint to bean (Phaseolus vulgaris L.) production around the world. Both snap beans and dry beans are affected. Root rot diseases can be caused by a variety of pathogens; however, Fusarium solani is a common causal agent. Fusarium root rot is a primary yield...

Needle diseases in Oregon coast range conifers

Creator:: Oregon State University. Extension Service, Kavanagh, Kathleen L., 1955-, Filip, Gregory M., and Rogers, William Reinhold
Abstract:: This publication discusses the environmental requirements of needle diseases, their potential impact on tree vigor, when disease levels signal a problem, and what you can do to minimize damage.
