F.  aPhenology and ripening of Vitis vinifera L. grape varieties in S??o Joaquim, southern Brazilba new South American wine growing region.h[electronic resource]  c2010  aThis study investigated the phenology and the ripening characteristics of Vitis vinifera grapes Cabernet Franc, Merlot, Sangiovese and Syrah in two consecutive vintages (2006 and 2007) in order to evaluate the adaptation of these recently cultivated varieties in S??o Joaquim, Santa Catarina State, Brazil. The phenological data observed, budburst, blooming, setting, v??raison and harvest were monitorated. In order to monitor the ripening levels of pH, total acidity, total soluble solids, maturation index, total monomeric anthocyanins, total polyphenols index and color index were analyzed.The results show that the phenological cycle from budburst to harvest occurred within a frame time of 191 and 219 days and the heat summation requirements varied between 1,161 and 1,340 GDD. The summing of the GDD results during the phenological cycle of the grapevines (budburst - harvest) characterizes S??o Joaquim-SC as ?Region I? (&lt 1,389 GDD), that is, a ?cold region? in terms of the Winkler Regions.The climatic parameters influenced the grapevine phenology and the grape ripening. The results showed that these different grape varieties had typical characteristics at maturity and indicated that they have potential for the production of fine wines, suggesting that S??o Joaquim-SC is suitable for Vitis vinifera grape growing.  aclimatic parameters  agrapes  aphenology  aripening  aVitis vinifera L1 aBURIN, V.
