Larry Williams, professor in the Department of Viticulture and Enology at UC Davis, made use of a large, wine grape variety trial at Kearney to determine the contribution that water relations and vine hydraulics have on growth differences among grapevine cultivars. The study will help determine the most appropriate parameters for managing irrigation across divergent varieties and growing locations.
Following Williams' field demonstration, the presentations move indoors and include:
- Ecology of mycotoxin-producing aspergilli in raisin vineyards by Teresa L. O'Keeffe and Jeffrey D. Palumbo of USDA Agricultural Research Service
- Effects of pre-harvest calcium chloride and chlorine dioxide applications on fruit quality of crimson seedless table grapes by Matt Fidelibus, UCCE specialist in the Department of Viticulture and Enology at UC Davis,
- Wood disease management options for grapevines in the San Joaquin Valley by Philippe Rolshausen, UCCE specialist in the Department of Botany and Plant Sciences at UC Riverside
- Movento in table grapes: understanding use patterns and expectations by David Haviland, UCCE advisor in Kern County
- Understanding wine oxidation by Andrew Waterhouse, professor in the Department of Viticulture and Enology at UC Davis
Kearney-based Fidelibus hosts the event every two years at the field station, 9240 S. Riverbend Ave., Parlier. For the 2013 event he has applied for 1.5 hours continuing education credit.
Fidelibus will be tweeting about GrapeDay 2013 from his Twitter account @grapetweets using the hashtag #ucgrapeday. All Grape Day participants and attendees who use Twitter are encouraged to participate in discussions related to the event using the hashtag #ucgrapeday.
Attendance at UC Grape Day 2013 is free, but online advance registration is requested for planning purposes. To register, go to http://ucanr.edu/sites/grapeday.
