Soil quality assessment of Willamette Valley soils and root colonization potential by arbuscular mycorrhizal fungi

Creator:: Allen, Natalie M.
Abstract:: Interest in measuring soil quality continues to increase worldwide in view of demands on land productivity and the necessity to preserve soil resources, yet identification of suitable indicators for soil quality assessment is still evolving. This study adapted 10 biological, physical, and chemical indicators of soil quality identified by the...

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...

The Influence of Vineyard and Winery Nitrogen Supplementation on Chardonnay and Pinot Noir Winemaking and Wine Quality

Creator:: Ruppel, Meghan L.
Abstract:: Nitrogen is a crucial nutrient required by yeast to successfully complete alcoholic fermentation. In particular, the concentration of yeast assimilable nitrogen (YAN) influences fermentation kinetics and the production of a range of volatile aroma compounds, both desirable and undesirable. YAN is naturally present in the grape, but producers can boost...

Determining the Impacts of Dormant Pruning Methods and Nitrogen Fertilization on Vitis vinifera 'Pinot noir' Bud Fruitfulness and Yield

Creator:: Ulmer, Miranda R.
Abstract:: The majority of grapes grown in Oregon are produced in Western Oregon’s Willamette Valley, where two-thirds of the acreage is planted to Pinot noir. The production of Pinot noir in the Willamette Valley comes at a high cost, and growers are seeking ways to increase profits while maintaining quality fruit...

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...

Effects of cover crop and vineyard floor management on young vine growth, soil moisture, and weeds in an establishing vineyard in the Willamette Valley of Oregon

Creator:: Fredrikson, Levi
Abstract:: Five vineyard floor management treatments were evaluated in a young vineyard in western Oregon to better understand the effects on vine growth and nutrition, soil moisture dynamics, and weed control during 2009 and 2010. Treatments included two mulched treatments where mowed alleyway residue was transferred in-row at rates of 1x...

Mycorrhizal Fungi on the Sagebrush Steppe: Benefits for Restoring Keystone Rangeland Plant Species

Creator:: Prado-Tarango, David E.
Abstract:: Arbuscular mycorrhizal fungi (AMF) are plant symbionts that associate with the vast majority of terrestrial plants species. The AMF colonizes the plant roots by penetrating the root cortical cells, where the fungi exchanges mineral nutrients with the host plant for photosynthates. This association exists as a complex system in which...

Spatiotemporal Phytohormone Distributions in Developing Pinot Noir Berries and the Effects of Two Viticulture Practices Thereon

Creator:: Schmidt, Joseph A.
Abstract:: In recent years, many studies have focused on the molecular and biochemical mechanisms regulating the development of wine grapes. The course of grape berry development is directed by genetic design and is mediated by phytohormones, which regulate grape berry growth and development by orchestrating a complex network of interacting genes,...

Water and Soil Management Practices to Enhance Plant Growth, Berry Development, and Fruit Quality of Northern Highbush Blueberry (Vaccinium corymbosum L.)

Creator:: Almutairi, Khalid F.
Abstract:: Drought and mandatory water restrictions are limiting the availability of irrigation water in many important blueberry growing regions and new strategies are needed to maintain yield and fruit quality with less water. Three potential options for reducing water use, including deficit irrigation, irrigation cut-offs, and crop thinning, were evaluated for...

Grape and Wine Aroma Influenced by Vine Nutrient Status, Vigor and Crop Levels in Oregon Pinot Noir

Creator:: Yuan, Fang
Abstract:: Wine volatile composition is one of the most important constitutes of wine quality, and it is greatly influenced by number of factors. The studies herein were conducted to evaluate the grape and wine aroma affected by different vine nutrient status, vigor and crop levels of Oregon Pinot noir. In the...
