| The control of leaf to fruit ratio by the practice of entire clusters removal from the vine upon berry set has been used in traditional vineyards in order to regulate yield and to improve chemical composition of the berries. Although this practice has been settled in temperate zones, little is known about grapevines behavior in tropical growing areas. The aim of this work was to evaluate the biochemical and agronomical responses of two Vitis vinifera cultivars (Merlot and Cabernet Sauvignon) grown in Caldas, Minas Gerais, Brazil, a new winegrape region. Grapevines were submitted to cluster thinning (0%, 50% and 75% of cluster removal) and trimming treatments (trimmed and untrimmed) imposed at pea size stage. The source-sink alteration by fruit removal and... |

| Abstract: The objective of this work was to evaluate the effect of different pruning methods on the yield performance and on the oenological potential of Vitis vinifera 'Nebbiolo', cultivated in high-altitude regions of Santa Catarina state, Brazil. The work was carried out in a commercial vineyard located in São Joaquim, SC, during the 2011/2012 and 2014/2015 crop seasons. The treatments consisted of four pruning systems: Guyot, Guyot Arch, and Cazenave (cane pruning systems), and cordon spur pruning. Production, vine balance, and grape composition were evaluated. In the cane pruning systems, a mean production of 2.0 kg per plant and Ravaz index below 2 were observed, with no change in the composition of the berries. In spur pruned vines, there was... |
