|Subject||Grapevine Clean Plant Workshop June 20, 2006|
Lectures included speakers from UC Davis who are currently working to improve the California R&C program. Dr. Deborah Golino, Director of Foundation Plant Services (FPS) in the College of Agriculture and Environmental Sciences at University of California, Davis, presented background information about the effects of the grapevine viruses on vineyard productivity and quality. Dr. Adib Rowhani, Plant Pathologist, Foundation Plant Services, UC Davis discussed the uses of different grapevine testing strategies in clean stock programs and for samples from field sites. Dr. Christian Leutenegger, Director, Lucy Whittier Molecular and Diagnostic Core Facility, School of Veterinary Medicine, talked about exciting progress in the use of real-time PCR for grapevine virus testing which may greatly reduce the turn around time for testing and improve the accuracy of results.
Bill Ogden, CDFA, outlined the process necessary for updating the Grapevine R&C Program and shared his experience with this and similar programs.
An important part of any certification scheme is the professional identification of the grapevine varieties in the program. Dr. Andy Walker, Department of Viticulture and Enology, UC Davis, one of the premier ampelographers in the world, talked about the techniques which can be used for this key step in clean plant programs.
There are a number of disease problems that affect grape planting stock that are not currently addressed in the California Grapevine R&C Program. Tom Burr, Professor of Plant Pathology, Cornell University, discussed strategies for controlling crown gall in nursery stock. Jerry Uyemoto, USDA-ARS Research Plant Pathologist, Davis, reviewed the biology of some of the new agents which he has discovered.
The day ended with a panel discussion of the benefits and difficulties of field diagnosis using laboratory testing led by UC Grape Advisor Steve Vasquez.
Adobe/Macromedia Breeze Presenter modules provide on-demand viewing of previously recorded PowerPoint presentations with streaming video and audio on the Web. They feature large, high-quality still images with synchronized audio and video; automatic linear playback or manual/random PowerPoint-like navigation; and a keyword search of slide text and notes. As Flash movies they are platform independent, but they do require Flash Player 6 or higher, which is currently installed on most computers. These modules were produced by UC Davis IET Mediaworks. Speakers and their presentations may be viewed in video on the following links:
