Study Pinot noir at two distinct locations in Oregon: a vigorous, dry farmed site (Willamette Valley) and a low vigor site (Southern Oregon). These vineyards will have the same cultivar and rootstock to reduce between site variability. The experimental vineyards will be monitored for vegetative growth, vine size and microclimate of treatments. Sunlight intensity measurements of the vine canopy in the cluster zone will be taken for all treatments concurrently. Vines will be monitored for photosynthetic efficiency. Vine microclimate will be monitored for light spectral quality and temperature throughout the season. At the end of the season, cluster weights and berry weights will be obtained to determine any treatment effects on fruit size. Shoot number per vine and cluster per shoot will be recorded during the growing season. Documents Grant with Oregon State University. Formerly 5358-12210-003-14G (8/2011).
