Sl. Staff et al., FRUIT ZONE LEAF REMOVAL INFLUENCES VEGETATIVE, YIELD, DISEASE, FRUIT COMPOSITION, AND WINE SENSORY ATTRIBUTES OF VITIS-VINIFERA L OPTIMA AND CABERNET FRANC, Canadian Journal of Plant Science, 77(1), 1997, pp. 149-153
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.
