The inheritance of volatile alcohols associated with frozen bush snap beans

Creator:: Toya, Dan K.
Abstract:: Inheritance of the volatile components in bush snap beans, O.S.U. 58-110 X 'Romano' cross and reciprocal, was determined using gas-liquid chromatographic technique with gas-entrainment on-column trapping. A sample of 10 to 14 pods averaging 5 grams from a single plant was found to be adequate for F₁, F₂, and backcross...

Influence of cover crop residue management on soil moisture, vine growth, and productivity in a pre-production vineyard in the Willamette Valley

Creator:: Curtis, Morgan A.
Abstract:: The use of cover crops in young vineyards is not widely accepted in the Pacific Northwest due to concerns of water and nutrient competition between the cover crop and vines. The last 2 years of a 4-year study started in 2009 are reported here. The study evaluated the use of...

Inducing and Evaluating Phenotypic and Cytometric Variation in Landscape Plants : Observations from Acer, Ornithogalum, and Penstemon

Creator:: Lattier, Kim Shearer
Abstract:: Hereditary variation is a vital component in the development of new and improved cultivars of landscape plants. Sources of hereditary variation include naturally occurring variation, recombination due to controlled crosses, artificial mutagenesis, and genetic modification via biotechnology. Here I explore all methods with the exception of genetic modification via biotechnology....

Nitrogen dynamics in field grown comice pears

Creator:: Sanchez, Enrique E.
Abstract:: The dynamics of N was studied in field grown Comice/Provence quince BA29 pears in Medford, Oregon. Total tree biomass, N content, and ¹⁵N evaluations suggest that young pears require little N (48 kg N ha⁻¹ yr⁻¹). About 45% of total tree N present in dormant trees was remobilized into new...

Aspects of manganese nutrition in filbert trees

Creator:: Silberman, Ricardo S.
Abstract:: Lime was applied at different rates to filbert trees grown in containers in an acid soil. As lime application rate increased, the leaf Mn and extractable soil Mn were significantly reduced. In control trees leaf Mn was over 1300 ppm, but no growth reduction or Mn toxicity symptoms were found....

RFLP analyses of interspecific hybrids of Phaseolus

Creator:: Kuo, Mei
Abstract:: Gene transfer via interspecific hybridization within Phaseolus has been limited by abnormal hybrid development and the rapid loss of hybridity in subsequent generations. The most advanced embryo development occurs in P. vulgaris x P. coccineus where mature seeds form. However, the reciprocal cross still results in abnormal embryos unable to...

Evaluating Alternative Soil Amendments for Organic Northern Highbush Blueberry Cultivation in Sub-Optimal Soils

Creator:: Retano, Andrea
Abstract:: Escalating demand for organic blueberries has driven a significant expansion of northern highbush blueberry (NHB; Vaccinium corymbosum L.) production area. This expansion is particularly pronounced in regions of the Pacific Northwest where native soil conditions are sub-optimal for NHB, notably east of the Cascade Mountain Range of Oregon and Washington,...

Behavioral responses underpinning resistance and susceptibility of honeybees to Tropilaelaps mercedesae

Creator:: Khongphinitbunjong, Kitiphong, de Guzman, Lilia I., Burgett, Michael D., Rinderer, Thomas E., and Chantawannakul, Panuwan
Abstract:: Behavioral responses of Apis cerana, Apis dorsata, and Apis mellifera to the ectoparasitic mite, Tropilaelaps mercedesae, were compared using two laboratory bioassays: cohorts of 50 caged worker bees and individual-caged worker bees, all of unknown ages. For the group bioassays, ten T. mercedesae were placed on the bodies of bees...
