MATURAÇÃO DA UVA 'BENITAKA' CULTIVADA EM CLIMA SUBTROPICAL.

Producers traditional of the fines table grapes, the regions of Pilar do Sul and São Miguel Arcanjo require studies related to the evolution of maturation in order to guarantee the harvest of fruits that meet market requirements. The aim of this work was to evaluate the maturation of the grape 'Benitaka' grown in subtropical climate. The experiment was conducted in a commercial vineyard of the grape 'Benitaka' grafted on the rootstock 420-A, in a pergola-type conduction system, in the seventh year of production, located in Pilar do Sul, SP, Brazil (23º 48 'S, 47º 42 'W and altitude of 689 m), in the production cycle of 2014/15. From the beginning of maturation, at 114 days after pruning (DAP), weekly sampling of berries was carried out to determine soluble solids (SS), pH, titratable acidity (AT), relationship SS/AT and reducing sugars (RS), extending the sampling of berries until harvest (156 DAP). The grape 'Benitaka' cultivated in the subtropical region showed good physicochemical characteristics at 156 days after pruning, with SS values of 15.99 ºBrix, AT of 0.49 % of tartaric acid, pH 3.73, relationship SS/AT of 32.68 and RS of 14.10 %.
