Vineyard managers must decide on the timing and amount of irrigation. In Oregon the need for irrigation differs greatly year to year and field to field based on micro climate, soil, root development, plant health, and root stock. We suggest the use of leaf water potential as a useful management...
Applied research is often motivated by the economic benefits it will give rise to. These benefits are due to either improved production techniques or new products. The realisation of these objectives depends much on the assessment of different research alternatives and allocation of resources between them. Also within aquaculture research...

Objectives:
To evaluate the impact of the ring nematode, Mesocriconema xenoplax on the physiology and productivity of phylloxera-resistant grape rootstocks as a basis for recommending rootstocks in the Pacific Northwest. Specific objectives for 2006:
Spring: Inoculate soil with AMF and M. xenoplax. Plant vines.
Growing season: Monitor plant growth, gas...
The report below and displays in the lobby summarize the first-year activities of the Oregon Vineyard Soil and Nutrition Initiative. This work has laid the foundations for OVID, the Oregon Vineyard Database, which will fill the second year of OVSNI and is discussed in the final sections.
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)...
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...
The objectives of this study are to determine:
• How the time of leaf pulling affects Pinot noir fruit quality and composition
• How the intensity of leaf pulling affects Pinot noir fruit quality and composition
• If there is a difference in fruit quality and composition when lateral leafs...
