  • Integration of conservation tilage and cover crops in broccoli production systems of the Pacific Northwest

    Creator:
    O'Brien, Timothy John
    Abstract:
    Field and greenhouse experiments were conducted in 1996 and 1997 to evaluate the effects of integrating conservation tillage and cover cropping on broccoli production as well as agroecological parameters. A field experiment was conducted during 1996-97 at the Oregon State University Horticulture Research farm near Corvallis, OR. The specific objectives...

  • Control of Lepidium latifolium and restoration of native grasses

    Creator:
    Laws, Margaret S.
    Abstract:
    Lepidium latifolium L. (perennial pepperweed, LEPLA) is an exotic invader throughout western North America. At Malheur National Wildlife Refuge (MNWR) in southeast Oregon, it has invaded about 10% of meadow habitats that are important for wildlife. This study's objective was to determine the most effective and least environmentally harmful treatment...

  • Shrub epiphyte communities in relation to stand management in forests of western Oregon

    Creator:
    Rosso, Abbey L.
    Abstract:
    This dissertation describes the epiphyte communities on tall shrubs in forests of western Oregon, with a focus on potential effects of management practices on these communities. Shrubs and other hardwoods have recently gained recognition as hotspots of diversity for epiphytes in young conifer forests of the region. Yet little is...

  • Possible associations of soluble carbohydrates with chemical desiccation and drought resistance in winter wheat

    Creator:
    Cerono, Julio Cesar
    Abstract:
    Drought is a major limiting abiotic stress influencing wheat production in many parts of the world. The erratic nature of water deficits makes breeding and selection for drought resistance deficient. In environments with late season drought stress, yield losses are usually associated with kernel abortion or reduction in kernel growth....

  • Water management effects on birdsfoot trefoil seed production

    Creator:
    García-Díaz, Carlos Alberto
    Abstract:
    There is no information available on water management of birdsfoot trefoil grown for seed. Information is also not available describing how to minimize seed losses due to shattering in order to obtain consistently high birdsfoot trefoil seed yields. The objectives of this research are to: (i) quantify crop water use,...

  • Effects of host resistance on Mycosphaerella graminicola populations

    Creator:
    Cowger, Christina
    Abstract:
    Mycosphaerella graminicola (anamorph Septoria tritici) causes Septoria tritici blotch, a globally important disease of winter wheat. Resistance and pathogenicity generally vary quantitatively. The pathogen reproduces both sexually and asexually, and the pathogen population is highly genetically variable. Several unresolved questions about the epidemiology of this pathosystem are addressed by this...
