  • Investigation of hop downy mildew through association mapping and observations of the oospore

    Creator:
    Parker, Thomas B.
    Abstract:
    Hop downy mildew is a devastating disease affecting hop requiring expensive fungicide applications throughout the growing season. Plant resistance is highly desirable and theorized as being decidedly quantitative with dominance and epistasis involved in resistance. An association mapping approach using a mixed-model was used to identify AFLP markers associated with...

  • The Pursuit of Hoppiness : Propelling Hop into the Genomic Era

    Creator:
    Hill, Steven T.
    Abstract:
    Hop (Humulus lupulus L. var lupulus) is a plant of great cultural significance, used as a medicinal herb for thousands of years, and for flavor and as a preservative in brewing beer. Studies of the medicinal effects of the unique compounds produced by hop have led to interest from the...

  • Towards Resolving Functional and Evolutionary Mysteries of the Large and Heterozygous Genome of Hop (Humulus lupulus) and the Cannabaceae Family Using Genomic Data Science

    Creator:
    Padgitt-Cobb, Lillian K.
    Abstract:
    Hop (Humulus lupulus L. var. lupulus) is a diploid, dioecious plant with an extensive history of cultivation and use in brewing, as a textile, and for its therapeutic properties. Hop is prized for its ability to produce a variety of aromatic and flavor compounds, as well as compounds with anti-microbial...

  • Induced Mutation for Improving Cascade and Centennial Hop

    Creator:
    Getty, Brooke A.
    Abstract:
    Hop, Humulus lupulus L. is a dioecious perennial species. The female hop plant produces flowers that mature into ‘cones’ which are used as a raw material in the beer brewing process to impart bitterness, flavor, and aroma. The craft beer industry in the current global beer market continues to experience...

  • Zinc-phosphorus relationships in five plant species

    Creator:
    Henning, Stanley John
    Abstract:
    The effects of zinc and phosphorus treatments on five different plant species were investigated in a greenhouse experiment. A second greenhouse experiment extended these investigations in sweet corn over a broad range of phosphorus treatments with and without adequate zinc nutrition to study phosphorus induced zinc deficiency. The plant responses...

  • Aluminum toxicity in the primary meristem of wheat roots

    Creator:
    Henning, Stanley John
    Abstract:
    The progression and consequences of aluminum toxicity were studied microscopically in the root tips of four wheat varieties representing different classes of Al tolerance. The root tips studied were collected from seedlings grown in nutrient solution cultures containing either sublethal or lethal Al treatments which were unique for each variety....

  • Diagnostic analysis for mechanical systems

    Creator:
    Henning, Scott A.
    Abstract:
    An analysis and modeling method of the diagnostic characteristics of a mechanical or electromechanical system is presented. Diagnosability analysis is especially relevant given the complexities and functional interdependencies of modern-day systems, since improvements in diagnosability can lead to a reduction of a system's life-cycle costs. The diagnosis process of a...

  • Riparian bird communities in Portland, Oregon : habitat, urbanization, and spatial scale patterns

    Creator:
    Hennings, Lori A.
    Abstract:
    Urban ecosystems are characterized by human disturbance and changes in the amount, types, and spatial arrangement of wildlife habitat. The relative importance of habitat and human associated variables to urban birds is unknown. In 1999, I surveyed spring bird and plant communities along 54 perennial streams in the Portland, Oregon...

  • Potential Heterotic Groups in Hop as Determined by AFLP Analysis

    Creator:
    Townsend, M. Shaun and Henning, John A.
    Abstract:
    Hop (Humulus lupulus L.) is a perennial, dioecious species in which the female inflorescence (cones) are harvested and used in the beer-brewing process to impart bittering and/or flavoring to beer. Hop breeders have typically utilized clonal selection and hybridization to develop new cultivars. The use of genetically diverse parents for...
