    Description
    Three different pruning methods (hedge [H], minimal [M], and standard spur [S]) pruning in combination with two trellis systems (bilateral cordon [BC], single canopy, and quadrilateral cordon [QC] divided canopy) on growth, yield, and fruit, and wine composition of Cabernet Sauvignon grown at the Oakville Experimental Vineyard was investigated over a period of four years (1988 to 1991). The data which follows represent fouryear means of S, H, and M pruning treatments (BC and QC data averaged together) respectively; node number per vine after winter pruning 48, 220, and 680; total shoots per vine 72, 151, and 250; average shoot length (cm) 150, 63, and 40; average shoot weight (g) 62, 16, and 6; total pruning weight/vine (kg) 3.91, 2.10 and 1.07; yield per vine 14, 5, 21.3, and 21.3 kg; clusters per vine 121, 259 and 419; berry weight (g) 1.19, 1.10 and 0.95; cluster weight (g) 120, 83, and 58; berries/cluster 101, 77 and 67; and 0 Brix it harvest 22.7, 22.1, and 20.8. The average date of harvest ofS, H, and M vines was Sept. 20, Oct. 7, and Oct. 9, respectively. At harvest, Hand M fruits had significantly lower titratable acidity, malate, and K than S fruits, but level of anthocyanin did not differ significantly between treatments. It is concluded that S and H pruned vines were capable of producing relatively high quality wines but not M pruned vines.
