Using rootstocks to manipulate vine physiological performance and mediate changes in fruit and wine composition

Creator:: Sampaio, Tiago Luís Barros
Abstract:: A rootstock trial was established in 1997 at the OSU Woodhall vineyard, located in the Southern Willamette Valley, which included two experiments. The first experiment was a factorial of four varieties grafted on to 9 rootstocks, and also as ungrafted vines (a split-plot design). The second experiment was a randomized...

Development of an adventitious shoot regeneration system in cherries

Creator:: Meneghelli, Luigi P.
Abstract:: Shoot regeneration in vitro is a difficult problem for cherry species. This study addressed three approaches to the problem, regeneration of adventitious shoots from roots and leaves of mature cherry clones, and from cotyledons of open-pollinated 'Royal Ann' cotyledons. Regeneration on roots occurred at a very low frequency. Adventitious shoots...

Optimization of Agrochemical Application Technologies, Strategies and Chemical Control of Spotted-wing Drosophila, Drosophila suzukii (Matsumura), Diptera: Drosophilidae as a Model Organism and Identification of Trisiloxane and Silane Surfactants in Agricultural Spray Adjuvants and Reference Materials

Creator:: Mermer, Serhan
Abstract:: Drosophila suzukii (Diptera: Drosophilidae) is an insect of global concern that causes serious damage to soft-skinned fruits. D. suzukii is widespread in North America, South America, Europe, and Asia and is listed as an invasive pest with strict quarantine protocols governing import and export. Given the damage caused by D....

Simple sequence repeat marker development and use in European hazelnut (Corylus avellana L.)

Creator:: Gürcan, Kahraman
Abstract:: New highly polymorphic simple sequence repeat (SSR) markers for European hazelnut (Corylus avellana L.). were developed from several sources. The markers were characterized, and segregation in a mapping population allowed to assign them to linkage groups. Their transferability across genera and species in the Betulaceae family was investigated. SSR markers...

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,...

Primocane-fruiting blackberries : the effect of summer-pruning, tipping, and chilling on primocane morphology, fruiting season, and yield

Creator:: Thompson, Ellen
Abstract:: The effect of primocane management on flowering and fruiting patterns was studied in primocane-fruiting blackberry (Rubus subgenus Rubus, Watson) cultivars 'Prime-Jan'® and 'Prime-Jim'® over two years. Primocanes that were "soft-tipped" (upper 2-5 cm removed) at 1.0 m were compared to un-tipped canes. In both years, soft-tipped primocanes developed 2-3 fold...

Low Maintenance Strategies and Challenges within Oregon School Landscapes

Creator:: Gould, Micah A.
Abstract:: Ornamental landscapes require considerable amounts of inputs, including but not limited to irrigation, mowing or pruning, fertilization, and pest management. However, school systems have limited budgets, which reduce their access to resources and labor hours. Therefore, the objective of this project is to identify ground covers that can compete with...

Alternative orchard floor management practices, soil quality, nitrogen fertilizeruptake, and apple tree growth and yield

Creator:: McDonald, Sarah Finger
Abstract:: Orchard floor management (OFM) practices can improve soil function and alter the soil biological community. Soil function is dependent on soil forming materials and on management practices but little is known about how OFM affect orchard soil quality, fertilizer N uptake, or tree growth and production. Research plots were located...

Impacts of crop level and vine vigor on vine balance and fruit composition in Oregon Pinot noir

Creator:: Vance, Amanda J.
Abstract:: Vineyard management strategies, including vineyard floor management and crop level management, can be used to influence vine vigor and fruit composition. Two studies were conducted to evaluate the impact of these practices on Pinot Noir in Oregon's Willamette Valley. Managing crop levels is common in cool climate vineyard production though...

Nitrogen, defoliation and new growth in almond (Prunus dulcis (Mill) D.A. Webb) nursery plants

Creator:: Bi, Guihong
Abstract:: The relationships between nitrogen (N), defoliation, and plant growth in nursery plants were studied using almond {Prunus dulcis (Mill) D. A. Webb) trees. In several experiments the effects of N source and availability on tree growth, N uptake, N remobilization, and nonstructural carbohydrates (TNC) were investigated to determine the most...
