Effects of Novel Sulfur Applications for pH Management of Calcareous Soil in a New Planting of Organically Grown Northern Highbush Blueberry (Vaccinium corymbosum L.) in the Columbia Basin

Creator:: Gregory, Alexander D.
Abstract:: Organically certified Northern Highbush Blueberry (NHB; Vaccinium corymbosum L.) production in the Columbia Basin region of Oregon and Washington is expanding. Soils in the region are typically calcareous and highly alkaline, often requiring pH adjustment to an ideal range of 4.5–5.5 to support the establishment of the acid-loving, ericaceous crop....

Pressure trunk injections of potassium as a possible short term corrective measure for potassium deficiency in sweet cherry (Prunus avium L.) and prune (Prunus domestica L.)

Creator:: Robbins, Scott Hill
Abstract:: The effect of pressure trunk injections of K₂HPO₄, and K₂SO₄. solutions on the mineral content, growth, yield and fruit quality of sweet cherry and mineral content of prune were investigated. A complimentary study presented in Appendix 1, was conducted to evaluate the short term effectiveness of K soil amendments, mulching...

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,...

High-Density SNP Genotyping of Tomato (Solanum lycopersicum L.) Reveals Patterns of Genetic Variation Due to Breeding

Creator:: Sim, Sung-Chur, Van Deynze, Allen, Stoffel, Kevin, Douches, David S., Zarka, Daniel, Ganal, Martin W., Chetelat, Roger T., Hutton, Samuel F., Scott, John W., Gardner, Randolph G., Panthee, Dilip R., Mutschler, Martha, Myers, James R., and Francis, David M.
Abstract:: The effects of selection on genome variation were investigated and visualized in tomato using a high-density single nucleotide polymorphism (SNP) array. 7,720 SNPs were genotyped on a collection of 426 tomato accessions (410 inbreds and 16 hybrids) and over 97% of the markers were polymorphic in the entire collection. Principal...

Relationships between endogenous phenolic compounds of rhododendron tissues and organs and cold hardiness development

Creator:: Chalker-Scott, Linda
Abstract:: The leaching of water soluble phenolic compounds from cold stressed Rhododendron leaves was found to be a reliable indicator of tissue damage. In sublethally stressed leaf tissues, more and novel phenolic compounds appeared and were hypothesized to be precursors of cell wall components such as lignin and suberin. Subsequent radiolabeling...

Sugar transport in strawberry fruit : uptake competition and developmental changes in invertase levels

Creator:: Scott, James Douglas
Abstract:: Mechanisms by which plant organs accumulate photoassimilate are important in determining final sink size and may involve invertase activity. Because strawberry fruit are strong sinks for sugars, changes in invertase levels during development and mechanisms of sugar uptake within the fruit were examined. Fruit from greenhouse-grown, day-neutral strawberries, (Fragaria X...

Microsatellite marker development and molecular characterization in highbush blueberry (Vaccinium corymbosum L.) and Vaccinium species

Creator:: Boches, Peter
Abstract:: Pre-existing Expressed Sequence Tag (EST) libraries (1,305 sequences) and a newly constructed microsatellite-enriched genomic library (136 clones) from the V. corymbosum cultivar 'Bluecrop' were screened for unique Simple Sequence Repeat (SSR)-containing sequences. Our goal was to develop a set of robust SSR markers for use in managing the National Clonal...

Weeds With a Purpose: Interseeding Cover Crops into Sweet Corn in Western Oregon

Creator:: Donaldson, Andrew R.
Abstract:: Cover crop establishment in late-season crops, like sweet corn, may be difficult due to the relatively short operational window following crop harvest. In regions like western Oregon, where fall-precipitation can occur when the crop is still in the field, cover crops may not be able to be planted, due to...

Partial purification and characterization of a zeatin Cis-trans isomerase from Phaseolus vulgaris L.

Creator:: Bassil, Nahla V.
Abstract:: Conversion of exogenous cis-zeatin to trans-zeatin in immature seeds of Phaseolus vulgaris L. led to the isolation of a cis-trans isomerase from the endosperm. The enzyme was purified over 2000-fold by chromatography on a series of FPLC (anion exchange, gel filtration, and hydrophobic interaction) and Concanavalin A columns. Non-enzymatic isomerization...

Frost hardiness of buds, flowers and fruit of pear (Pyrus communis L.)

Creator:: Strang, John George
Abstract:: Spring frost damage to pears in the Pacific Northwest frequently results in substantial crop losses. This research was undertaken to investigate the effects of frost on pear buds, flowers, and fruit through controlled freezing tests and field studies in order to better understand the frost phenomenon and refine frost protection...
