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)...

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...

Creator:: Lee, Baek Soo and Jarvis, W. Todd
Abstract:: The Metolius River basin is a sub-basin of the Deschutes Basin within central Oregon. Considered one of the crown jewels of the state, this historically undisturbed basin drew attention in 2009 because the Oregon legislature designated the basin as the first Area of Critical State Concern (ACSC) under the state’s...

Creator:: Gonzalez-Pinzon, Ricardo, Haggerty, Roy, Argerich, Alba, Acker, Sarah, and Myrold, David
Abstract:: After three decades of active research in hydrology and stream ecology, the connection between solute transport, stream metabolism and nutrient dynamics is still unresolved. This existing gap obscures the functionality of stream ecosystems and how they interact with other landscape processes. To date, determining rates of metabolism is accomplished with...

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....

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...

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...

Creator:: Price, Steve, Lombard, Porter, Connelly, Anne, and Watson, Barney
Abstract:: Objectives: · Evaluate canopy management options available to Oregon growers for their effects on yield, grape composition, and wine quality. · Investigate the relationships between vine growth, cluster environment, grape composition and wine quality. · Develop techniques that improve the capabilities of Oregon winegrape growers to obtain consistent yields with...

Creator:: Price, Steve and Lombard, Porter
Abstract:: Objectives: 1. Evaluate canopy management options available to Oregon growers including trellising and pruning for their effects on yield and grape composition. 2. Investigate the relationships between vine growth, cluster environment cluster morphology, and grape composition. 3. Develop techniques that improve the capabilities of Oregon winegrape growers to maximize wine...
