E.F. Gris, V.M. Burin, E. Brighenti, H. Vieira, and M.T. Bordignon-Luiz. 2010. Phenology and ripening of Vitis vinifera L. grape varieties in São Joaquim, southern Brazil: a new South American wine growing region. Cien. Inv. Agr. 37(2): 61-75. This 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 São Joaquim, Santa Catarina State, Brazil.The phenological data observed, budburst, blooming, setting, véraison 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 São Joaquim-SC as "Region I" (< 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 São Joaquim-SC is suitable for Vitis vinifera grape growing.
<p style="text-align: justify;">Santa Catarina State (SC) is a new grape growing region in Southern Brazil where 300 ha have been planted with <em>Vitis vinifera</em> L. since 2000. The annual production of this region is 3,944 tons of grapes and 1,549,000 liters of wine.</p><p style="text-align: justify;"><strong>Aims</strong>: To evaluate the influence of climate and vineyard altitude on the phenology and ripening as well as the suitability of five new grape growing regions of SC for Cabernet-Sauvignon variety for two vintages (2005 and 2006).</p><p style="text-align: justify;"><strong>Methods and results</strong>: Physicochemical analyses were performed on grape berries at 10-day intervals from véraison to harvest. Classification of the bioclimate according to the Winkler and Fregoni indices was also carried out for a long time period for these areas. Climate was strongly correlated with phenological precocity indices. Four Winkler Regions were established and the Fregoni index ranged from 402 to 1,466 for these regions.</p><p style="text-align: justify;"><strong>Conclusions</strong>: A positive relationship was observed between altitude, air temperature and the annual vine cycle duration. In general, these Cabernet- Sauvignon grapes showed a good potential for winemaking mainly in Regions II and III of the Winkler scale.</p><p style="text-align: justify;"><strong>Significance and impact of the study</strong>: Given the present and possible future changes in the global climate, the wine industry may be required to find new locations for viticulture. In this context, this research presents new grape growing regions which are promising for the cultivation of <em>Vitis</em> <em>vinifera</em> grape varieties in Brazil.</p>
Resumo -O objetivo deste trabalho foi avaliar tendências nas séries climáticas e nos índices agroclimáticos para o cultivo da videira na região dos Vales da Uva Goethe, em Santa Catarina. A região apresenta clima mesotérmico úmido. Foram utilizados dados de temperatura máxima e mínima do ar, do período de 1924 a 2010, e de precipitação pluvial, de 1955 a 2010. O teste de Mann-Kendall foi utilizado para avaliar a tendência nas séries, cuja magnitude foi estimada pela declividade mediana determinada pelo teste de Theil-Sen. Foi observada tendência de aumento nas séries de temperatura mínima do ar, em escala anual, bem como nas estações do ano. Quanto à temperatura máxima, somente houve tendência de aumento na série de verão. Em relação aos índices agrometeorológicos, foi observada tendência de diminuição do número de geadas, diminuição do período entre a brotação e a colheita, aumento da soma térmica e dos índices de Huglin e de frio. Foram evidenciadas tendências de aumento da precipitação pluvial total anual e da precipitação no período de crescimento da videira, bem como aumento do número de dias, com chuva igual ou superior a 20 mm, e aumento na temperatura mínima e noturna.Termos para indexação: aquecimento global, climatologia, índice de frio, mudanças climáticas, precipitação pluvial, soma térmica. Climate trends and production of grapes in the Region of Goethe Grape Valleys, BrazilAbstract -The objective of this work was to evaluate the trends in climate series and in agroclimatic indices for growing vines in the Region of Goethe Grape Valleys, in the state of Santa Catarina, Brazil. The Region has a mesothermal humid climate. Maximum and minimum air temperatures, from the years 1924 to 2010, and rainfall data from 1955 to 2010 were used. The Mann-Kendall's test was used to evaluate the series trend, whose magnitude was estimated by the median slope determined by the Theil-Sen test. An increase trend was observed in the series of minimum air temperature, at the annual scale, as well as in the seasons of the year. For the maximum air temperature, there was a significant increase trend only in in the summer series. For the agrometeorological indices, a significant trend of decrease in the number of frost events was observed, reduction of the time between sprouting and harvesting, and increase trends in thermal summation and on the Huglin´s and cold indexes. Increase trends were evidenced for the annual total rainfall and for rainfall during the vine growth period, as well as for the number of days with rain equal to or higher than 20 mm, and for the minimum and night temperatures.
