“…Cabernet Sauvignon in the conditions of Bento Gonçalves-RS noted that the high defoliation had influence on the phenology (maturation delay) and on the production potential (11% n° of clusters per plant) in relation to the control and to the intermediate defoliation (25% and 50%), there was a moderate control of growth (-9,9% branches, -11,6% foliar area) followed by an increment in the number of berries per cluster (+23%), with lesser weight and individual diameter, favoring the relation peel/pulp (+5,8%), which is beneficial for oenological purposes. ANZANELLO et al (2011) observed that the treatments of defoliation performed up to the height of the clusters in the vine cultivars did not influence in the production per plant, cluster mass, AT, SS and pH of the wort, and that the localized removal of leaves up to the clusters height, during the beginning of the berries maturing, do not alter the quantitative and qualitative variables of the fruits. Moreover, they verified that for the 'Niagara Branca' and 'Concord' cultivars the defoliation performed above the clusters causes a maturation delay of the grapes and negatively affects the physical-chemical characteristics of fruits.…”

“…Thus, the variation between 2.82 and 3.05 found in this present study was slightly below that indicated for the variety. Anzanello et al (2011), when studying the Niagara, Concord, Cabernet Sauvignon and Merlot varieties at different levels of defoliation, concluded that the removal of leaves up to the height of the bunch at the beginning of ripening of the berries does not change the quantitative and qualitative variables of the fruits. The same authors also verified that, for Niagara and Concord, the defoliation performed above the bunches caused a delay in the maturation of the grapes, negatively affecting the physicalchemical characteristics of the fruits.…”

“…Com a poda verde foram removidas todas as folhas abaixo da inserção do primeiro cacho do ramo. Esse nível de desfolha vem sendo adotado nos trabalhos de autores como Anzanello et al (2011) e Mandelli et al (2008.…”
