Effects of pruning on yield, three basic measures of fruit composition and cane carbohydrate concentration in Vitis vinifera cv. Pinot Noir vines were investigated in a cool climate wine area of Tasmania (Australia) from 2002 to 2004. Four pruning treatments comprising of 10, 20, 30 and 40 nodes per vine were imposed on 8-year-old vines. Bunch number, bunch weight, berry number and berry weight were measured. Cane samples were collected in the second year for tissue carbohydrate analysis. Fruit was analysed for pH, skin colour and sugar level. For each of the yield components measured there was a significant year effect but no interaction between year and pruning treatment. In each of the three years pruning to a higher bud number decreased the number of bunches per bud but no other yield component. Pruning treatment significantly affected starch content of the winter canes but not soluble carbohydrate levels. Pruning affected both pH and colour of fruit but not sugar concentration.
