Abstract
The influence of fruit zone leaf removal treatments (0, 50, and 100%) on grapevine canopy structure, incidence of bunch rot (Botrytis cinere a Pers.:Fr.), yield components, fruit and wine composition and wine se nsory attributes was studied on Vitis vinifera L. 'Optima' and 'Cabern et franc'. The 50 and 100% leaf removal reduced leaf layer number, per cent interior leaves and percent interior clusters. Yield was reduced between 29 and 46%. Severity of bunch rot in Optima and incidence and severity for Cabernet franc were reduced by leaf removal. Leaf removal improved colour, aroma and palatability of both Optima and Cabernet f ranc wines.
