Effect of viticultural practices on yield and volatile composition of ‘Cabernet Sauvignon’ grapes

‘Cabernet Sauvignon’ is a vigorous grapevine that develops herbaceous aromas in grapes. Canopy management practices can impact physiology, and as consequence the photosynthesis, fruit yield, grape composition, improve quality of fruit. Leaf removals apical leaf on grapevines have been shown to reduce aromas. However, little known, about effect use girdling concentration volatile compounds Thus, objective this study was evaluate basal removal (BLR), girdling, plus cutting regions canopy (girdling + CAC), Fruit chemical were analysed all treatments. Girdling CAC showed reduction total acidity, however, increases soluble solids, fruity observed comparison BLR control (no-canopy treatment). Controls highest related unripe characteristics On other hand, grapes floral character. These results suggest modifies composition grapes, techniques increase
