Manipulating Soil Moisture and Nitrogen Availability Part II: Effects on Pinot noir Must and Wine Composition

Creator:: Watson, Barney, Godard, Mee, and Chen, Hsiao-Ping
Abstract:: The objectives of this study are to evaluate the effects of manipulating soil moisture and nitrogen availability using different approaches, including supplemental irrigation, nitrogen addition to the soil or to the leaves, and the elimination of competition for water and nutrients between the ground cover and the grapevines by tilling....

Manipulating Soil Moisture and Nitrogen Availability Part II. Fermentable Nitrogen Content and Must and Wine Composition

Creator:: Watson, Barney, Wall, Kate, Specht, Anna, Chen, Hsiao-Ping, and McDaniel, Mina
Abstract:: An approximation of the total yeast fermentable nitrogen content in juice or must is taken as the sum of the nitrogen available from ammonia and the alpha-amino acids present (Bisson 1991 ; Dukes and Butzke 1998 ; Jiranek, Langridge, and Henshcke 1995). Recommended levels of fermentable nitrogen needed by yeast...

Development of Viticultural Practices to Improve Winegrape Performance Experiment II: Effect of Crop Level on Fruit Composition of Pinot noir Grapes [1998-1999]

Creator:: Taylor, Patrick and Candolfi-Vasconcelos, M. Carmo
Abstract:: A broad range of factors influence wine grape quality and manipulation of these factors 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...

Development of Viticultural Practices to Improve Winegrape Performance Experiment II: Effect of Canopy Location on Yield Components and Fruit Composition in Pinot noir Grapevines Trained to the Scott Henry Trellis System [1997-1998]

Creator:: Ratliff-Peacock, Joey, Candolfi-Vasconcelos, M. Carmo, and Henry, Scott
Abstract:: For this trial, established Pinot noir vines, located on the valley floor of the Umpqua Valley in Oregon were used. In 1996 and 1997 sixteen vines trained to the Scott Henry trellising system were separated into four different quadrants, determined by shoot orientation: Bottom canopy, shoots trained toward the ground;...

Evaluation of Grape Rootstocks for Resistance to Crown Gall and Nematodes [1995-1996]

Creator:: Miller, Marilyn L., Pinkerton, Jack, and Moore, Larry W.
Abstract:: Grafted grapevines will become increasingly important in Oregon vineyards in order to prevent loss of plants to phylloxera infestations. Several rootstocks are now being evaluated in Oregon for horticultural traits and characteristics related to wine quality. Resistance or tolerance to other plant diseases affecting grapevines needs to be examined as...

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)...

Monitoring of Soil Moisture: Methods, Improving Wine Quality and Extent of Wetting

Creator:: Selker, John, Candolfi-Vasconcelos, M. Carmo, and Rojas, Wilson
Abstract:: The Willamette valley has grown to be an important source of high quality grapes for the production of wine. These grapes are a very high value crop that has proven to be profitable in this region. Irrigation of this crop has been limited largely to the establishment stage, with most...
