  • Design and testing of an integrated wildlife-wind turbine interactions detection system

    Creator:
    Flowers, Jeremy Matthew
    Abstract:
    Bird and bat mortalities caused by interactions with wind turbines is a critical concern that requires addressing for conservation purposes. Deploying a low cost sensor array will be instrumental during site permitting, conducting impact assessments of existing wind farms, and assessing efficacy of wildlife mortality mitigation or wildlife deterrent technologies....

  • Field and greenhouse studies with Acalymma and Diabrotica : protection of cucurbits with a kaolin-based particle film : feeding damage to cucumbers with and without cucurbitacin

    Creator:
    Reich, Joel A.
    Abstract:
    Research was conducted in the field and greenhouse to determine if a kaolinite-based particle film, Surround®, would reduce colonization and early season feeding damage in cucurbits by the Western Striped Cucumber Beetle, Acalymma trivitattum (Mannerheim). Greenhouse studies were designed to determine effect of particle film on cucumber dry weight production...

  • Fruit color development in red pears

    Creator:
    Dussi Dehais, Maria Claudi
    Abstract:
    A fruit color descriptive study was conducted on 'Max' and 'Sensation' Red Bartlett, 'Columbia' and 'Gebhard' Red Anjou, 'Rogue Red', 'Rosired', 'Red Clapp' and 'Cascade' red pear varieties. A parallel comparative study was done to test differences between related red strains. 'Max' was compared with 'Sensation' in three different growing...

  • Microbial and biochemical dynamics of ectomycorrhizal mat and non-mat forest soils

    Creator:
    Kluber, Laurel A.
    Abstract:
    Dense hyphal mats formed by ectomycorrhizal (EcM) fungi are prominent features in Douglas-fir (Pseudotsuga menziesii) forest soils and have been estimated to cover up to 40% of the forest floor in some stands. Although previous studies have examined various aspects of EcM fungi, little is known about their associated microbial...

  • Farmer perspectives on success and challenges : a study of small farms in Oregon's Willamette Valley

    Creator:
    Pool, Kristin E.
    Abstract:
    This thesis investigates the success of and challenges facing small farmers operating direct marketing farm businesses in Oregon's Willamette Valley. This qualitative study utilizes participatory methods to gain the unique perspectives of small farmers regarding their success and challenges. Small farms are important players in local food systems and ensuring...

  • Efficacy of water, sodium hypochlorite, peroxyacetic acid, and acidified sodium chlorite for reducing microorganisms on in-shell hazelnuts

    Creator:
    Weller, Lisa D.
    Abstract:
    Hazelnuts are commonly consumed raw and are valued for their numerous health benefits and antioxidant properties. Increased foodborne illness outbreaks associated with Salmonella and Escherichia coli O157:H7 contamination of tree nuts and peanuts generate a need for improving agricultural sanitation procedures. Food-safe chemical sanitizers have shown promise for reducing pathogenic...

  • Development of PCR-based markers for identifying grape rootstocks

    Creator:
    Xu, Hong, 1968-
    Abstract:
    Sequence-specific PCR markers were derived from one new and eight previously identified random amplified polymorphic DNA (RAPD) markers for the purpose of identifying grape (Vitis) rootstocks. The markers were developed because the RAPD assay was found to be inconsistent and the original RAPD markers unreliable. Southern hybridization analysis of the...

  • Studies on the etiology and epidemiology of bull's eye rot of pears

    Creator:
    Henriquez, Jose Luis, 1961-
    Abstract:
    The objective of this dissertation is to introduce low-cost processing methods for the fabrication of ZnO transparent thin-film transistors (TTFTs). A novel method for depositing ZnO body layers via spin-coating of a zinc nitrate-based spin solution is presented. The processing conditions of spin-coated ZnO are optimized to produce continuous and...

  • Enhancement of biological control with beneficial insectary plantings

    Creator:
    Colley, Micaela Ruth
    Abstract:
    Five field experiments were conducted to evaluate the relative attractiveness of potential beneficial insectary plants to aphidophagous hover flies and parasitic Hymenoptera and the effectiveness of interplanting selected flowering plants in a broccoli field to enhance biocontrol of the cabbage aphid and green peach aphid. In 1996 we established a...

    Abstract:
    The availability of new pear rootstocks could be increased by development of an efficient micropropagation system. Many P. calleryana, P. betulifolia and P. communis rootstocks are resistant to many pear diseases and are graft compatible with leading cultivars. Explains of three potentially useful rootstock selections P. calleryana Decne 'OPR 157',...
