Effect of crop level on yield components, fruit and wine composition, and wood carbohydrate reserves of Pinot noir grapes

Creator:: Brasher, Erik W.
Abstract:: Crop thinning trials were studied during two seasons at two locations in the northern Willamette Valley of Oregon. At Willakenzie Estate (site #1), research vines were Pinot noir clone Dijon 113 on 3309 rootstocks trained to a double Guyot. Vines were established in 1996 at a spacing of 2.5 x...

Effects of Crop Level on Fruit Composition of Pinot noir Grapes

Creator:: Brasher, Erik and Candolfi-Vasconcelos, M. Carmo
Abstract:: A broad range of factors influences wine grape quality and its manipulation has stimulated interest among grape growers, wine makers, and research scientists alike. One such factor affecting wine grape quality is crop level, particularly for Pinot noir. Since the capacity of a vine to ripen fruit depends largely on...

Evaluation of phylloxera-resistant rootstocks for the cultivars Pinot noir, Chardonnay, Pinot gris and Merlot

Creator:: Shaffer, Ray and Candolfi-Vasconcelos, M. Carmo
Abstract:: Vineyard acreage in Oregon continues to increase at a rapid pace. In the past two years alone 1600 acres of new vineyard land have been planted (Rowley et al., 2000). Much of this has been on phylloxera-resistant rootstocks. This practice is strongly encouraged, since it is the only practical way...

Assimilate Partitioning in Vitis vinifera During the Reproductive Period

Creator:: Finger, Sarah A. and Candolfi-Vasconcelos, M. Carmo
Abstract:: Objectives of proposed research: 1. Investigate the relationship between abscisic acid (ABA) and auxins and the regulation of carbon partitioning. 2. Investigate the origin of ABA present in the fruit during ripening and attempt to modify the partitioning pattern through manipulation of endogenous ABA levels using mefluidide (ABA biosynthesis promoter)...

Manipulating Soil Moisture and Nitrogen Availability to Improve Fermentation Behavior and Wine Quality. Part I: Vine Physiological Performance, Yield Components, Ripening Dynamics, and Fruit Composition

Creator:: Silva, Elisabete, Sampaio, Tiago, and Candolfi-Vasconcelos, M. Carmo
Abstract:: This study integrates various vineyard practices that may improve nitrogen availability to the vine, particularly during ripening . Different strategies aimed at improving fermentation behavior and wine quality are being evaluated. This study aims to optimize fruit quality and maximize the juice nitrogen fraction that can be used by yeast...

The effect of rootstock on the performance of the Vitis vinifera cultivars Pinot noir, Chardonnay, Pinot gris and Merlot

Creator:: Shaffer, Raymond Glen
Abstract:: This study reports finding of two rootstock experiments planted in 1997. The purpose of the first experiment was to evaluate the performance of Pinot noir on 19 phylloxera-resistant rootstocks and as an ungrafted vine. The purpose of the second experiment was to evaluate the performance of V. Vinifera cultivars Pinot...

The effect of nitrogen, irrigation, and cultivation on Pinot noir juice and wine composition from the Willamette Valley, Oregon

Creator:: Wall, Katherine Elizabeth
Abstract:: This study investigated how manipulating vineyard nitrogen status, irrigation levels and cultivation practices would effect nutrient composition, and anthocyanin and phenolic accumulation in Pinot noir juice and wine from a commercial Willamette Valley Oregon vineyard. Pinot noir fruit was sourced from a vineyard trial in the Benton Lane Vineyard, located...

Evaluation of Vitis rootstocks for tolerance to low soil pH

Creator:: Taylor, Patrick Andrew
Abstract:: The purpose of this study was to determine the relative tolerance of grafted Vitis rootstocks to low soil pH. In this capacity, the data may be pooled with results from previous investigations to increase the overall aptitude profile of Vitis rootstocks. A potential application of this information is that the...

Effect of soil moisture manipulation and nitrogen application on leaf gas exchange, fruit composition, and carbohydrate storage of Pinot noir and Chardonnay grapevines in the Willamette Valley

Creator:: Howe, Jessica
Abstract:: This study integrates various vineyard practices that may improve nitrogen availability to the vine, particularly during ripening. Different strategies aimed at increasing yeast assimilable nitrogen in the fruit at harvest have been evaluated. This study seeks to improve fermentation behavior and wine quality through vineyard practices used for nitrogen management....
