Abstract

Under drought conditions the influence of zero pruning (ZP) and hand pruning (HP) on yield, total soluble solids (degrees Brix), sugar production, dry matter production and total leaf area development of Grenache vines (Vitis vinifera L.) was assessed from 1988 to 1996. ZP was superior to HP for yield, sugar production and dry matter production. Total soluble solids were occasionally reduced by ZP. These effects of ZP can be explained by the larger total leaf area. These results are specifically important with regard to low-yield viticulture with a severely limited total leaf area.
