| Abstract The Cabernet Sauvignon (CS) cultivar is one of the most widely planted wine grapes in Brazil. The final grape quality depends on the clone type, rootstock, and the terroir. This study aims to assess and characterize the effects of seven combinations of CS clones grafted onto two rootstocks on the physical–chemical parameters and productivity of the grapes in the highland of southern Brazil, during the 2012-2013, 2013-2014, 2014-2015, and 2015-2016 growing seasons. The experiment was carried out in a 14-year-old commercial vineyard, located in São Joaquim municipality, Santa Catarina State, trained on a vertical shoot position system on a double cordon with spur pruning. The treatments consisted in a completely randomized experimental block of the... |

| The change of grape (Vitis vinifera) harvest from summer to winter through double pruning management has improved the fine wine quality in southern Brazil. High altitude, late cultivar and grafting combination all need to be investigated to optimize this new viticulture management. For this purpose, this study was carried out during the 2011 and 2012 growing seasons in a high altitude region of the state of Minas Gerais, Brazil, using eight grafting combinations for five year old Cabernet Sauvignon vines. The stem water potential, photosynthetic rate and stomatal conductance were not affected by rootstock type. The rootstocks IAC 766 and 101-14 induced, respectively, the highest and lowest vegetative vigor in Cabernet Sauvignon, as shown by leaf area and... |

| ABSTRACT The agronomical responses of Chardonnay, a variety indicated for sparkling wine production, is influenced by the vineyard management and the edaphoclimatic conditions of the region. The objective of this study was to evaluate the effects of two pruning types (Royat and double Guyot) on vegetative and reproductive development of Chardonnay vine growing at high altitude in the Brazilian southeastern region. The experiment was carried out in a commercial vineyard located at 1,280 m of altitude in Divinolândia, São Paulo State, Brazil. The Chardonnay vines (clone 96), grafted onto 1103 Paulsen rootstock and trained in a vertical shoot positioning trellis system, were assessed. Vegetative vigor, bud fruitfulness, production and physicochemical... |
