WineEast Grapegrowing Control vines showed sporadic distribution of clusters in the canopy. The five-node hedging treatment is pictured at right. and whole vines sustained winter injury, but there were no dif- ferences among the pruning treatments (even though there was a trend with non-pruned vines sustaining the most injury.) as expected, at harvest non-pruned vines had the highest num- ber of clusters and yield (4.8 tons per acre), and spur-pruned and two-node hedge-pruned vines had the lowest (0.6-0.7 tons per acre); cluster number and yield in five-node hedging were intermediate (2.3 tons per acre.) in other words, the higher the pruning severity, the lower the yield; thus the yield response was attributed to pruning severity rather than to freezing injury. how- ever, vine size (expressed as pruning weight of 1-year-old wood) was the smallest in non-pruned vines and the largest in the remaining treatments. all pruned vines were within the optimal range; non-pruned vines were below the optimal range and thus considered out of balance. further, non-pruned vines had the highest ri and were over- cropped; spur and two-node hedged vines had the lowest ri and were under-cropped; the five-node hedged vines were balanced since ri value was within the ideal range. as predicted, it took the least time to prune and remove wood from the trellis with - SIHA YEAST - Labels for Wine, Spirit & Food Offering: Flexo Roll Printing Indigo Sheet & Roll Printing Die Cut, Foil Stamping & Embossing Branding & Design Services Knowledgeable of TTB Regulations Eastern Distributor for www.wrightlabels.com Tel (800) 678-9019 62 Wines & Vines APRiL 2012 Beco Filter Sheets, Siha Yeast, EvOAK Oak Alternatives, Parker-dh Membranes, Chillers, N2 Generators, Zander Air Products SEGUFIRTNE C O AK ALTERNATIVES - BECOPAD - DECAN TERILE FILTRATION - WATER FILTRATIO T E R - S N ( l e f t)
