摘要: The objective of this work was to evaluate the chemical composition 'Cabernet Franc' grape subjected different levels shoot topping. experiment conducted in 2008 and 2009 vintages, and topping consisted of: control, without topping; reductions 15, 30, 45% in total leaf area. effect intensity on Franc' grape berries observed. A reduction 26% vegetative canopy through a moderate topping increased total polyphenol index anthocyanin content. Shoot is practice that must be carried out with caution, since severe topping, i.e., greater than area, may negatively impact grape quality by reducing content soluble solids decreasing polyphenol index anthocyanins berries.
