Title: Influence Over a Ten-Year Period of Training System on Yield and Fruitfulness of Table Grape Cultivars
Authors: D. Wolfe and G.R. Brownn
Abstract:
Twenty Grape cultivars [Vitis species, (L.) Batch], planted Spring, 1983, were trained to the four-cane Kniffin (KN) and to the Geneva Double Curtain (GDC) system over a ten-year period. Yield per vine, pruning weight, number of nodes, cluster weight, berry number per cluster, berry weight, and percent fruit soluble solids were recorded annually through 1993. Across cultivars, vines trained to the GDC averaged 2 kg more yield per vine per year than vines trained to the KN. Yield per noae and the number of clusters per vine also were greater for vines trained to the GDC system.
