Abstract:Visando à produção de vinho e suco de uva de melhor qualidade, o objetivo desta pesquisa foi aumentar a relação de sólidos solúveis totais/acidez total titulável (SST/ATT), conhecida como flavor, da uva 'Bordô', com o uso de reguladores vegetais e avaliar os efeitos destes produtos nas demais características físico-químicas dos frutos. O trabalho foi realizado durante duas safras, 2009/2010 e 2010/2011, em Bocaiuva do Sul-PR. As variáveis físicas analisadas foram: comprimento e largura dos cachos; diâmetro das… Show more
“…These values were similar to those reported by Ribeiro (2013) for the region of Jundiaí-SP (157.7g). On the other hand, Bordô cultivar showed the lowest bunch fresh weight value (93.3g) similar to that obtained by Chiarotti et al (2011) for Bocaiuva do Sul-PR. For Isabel Precoce, Isabel and Concord cultivars, intermediate bunch fresh weight values were obtained, ranging from 126 to 148.4g.…”

“…Values obtained for Isabel cultivar in VSP training system were higher than those observed in northern Paraná (ASSIS et al, 2011), Serra Gaúcha (RIZZON and MIELE, 2006);Caldas (PEREIRA et al, 2008) and Muzambinho, in Minas Gerais (APARECIDO et al, 2017). Bordô cultivar showed the lowest soluble solids content (15.1 °Brix), similar to values reported by Chiarotti (2011) for Bocaiuva do Sul-RS and lower than those observed by Pereira et al (2008) in Caldas-MG. BRS Violeta and Concord cultivars presented intermediate values, respectively 17.2 and 16.9 °Brix, higher than those observed for 'Concord' cultivated in Eldorado do Sul (ANZANELLO et al 2008) and Caldas-MG (PEREIRA et al al., 2008). For BRS Violeta cultivar, Aparecido et al (2017) observed, even during the winter season, total soluble solids content of 15.7 °Brix, while Silva et al (2017) reported value of 18.4 °Brix for 'BRS Violeta' in the region of Jundiaí-SP.…”
The increase of rural tourism activities has led growers to use different grape cultivars for the production of wine and/or juice. Thus, the aim of this study was to evaluate the phytotechnical characteristics of grapevines and physicochemical characteristics of grape must obtained for Bordô, Isabel Precoce, BRS Violeta, Isabel and Concord cultivars in different training systems: vertical shoot position; Y-shaped trellis and V-shaped trellis with double spur cordon. The experimental design was randomized blocks for comparison of cultivars within each training system and analysis of the main components for productivity variables was carried out. BRS Violeta cultivar showed higher bunch weight values regardless of training system. Bordô cultivar showed lower yield values and soluble solids content in comparison to other cultivars. Isabel and Isabel Precoce cultivars in the evaluated training systems showed higher soluble solids content. Principal component analysis allowed verifying that in Y-shaped trellis and V-shaped trellis with double spur cordon training systems, cultivars were related to higher yield.

“…Para a variável sólidos solúveis, observaram-se valores superiores para a variedade Isabel Precoce nas duas safras avaliadas, sendo que, na safra 2015/2016, os valores de sólidos solúveis da variedade Isabel Precoce foram similares aos da variedade Bordô, apresentando 15,6 e 15,3 ºBrix, respectivamente. De acordo com Chiariotti et al (2011), a uva 'Bordô' produzida nas Regiões Sul e Sudeste apresentam deficiência na maturação, prejudicando o teor de sólidos solúveis das bagas, refletindo no suco, que exige um limite mínimo de 14°Brix (BRASIL, 2018). *Médias seguidas da mesma letra, na linha, não diferem entre si pelo teste Tukey a 5% de probabilidade de erro.…”
A região de Lages, Santa Catarina, possui grande potencial para o cultivo de espécies frutíferas de clima temperado e nesse contexto o cultivo de uvas para processamento surgem como alternativa viável para geração de renda e emprego na região, atendendo uma demanda existente no estado de Santa Catarina. Diante disto, tem-se como objetivo deste trabalho, avaliar o potencial produtivo e qualitativo de três variedades de uvas para processamento cultivadas em Lages, Planalto Sul de Santa Catarina, Brasil. O presente estudo foi realizado em um vinhedo experimental localizado no munícipio de Lages, durante as safras 2015/2016 e 2016/2017. Foram avaliadas plantas de Vitis labrusca, variedades Bordô, Concord e Isabel Precoce. Avaliou-se: fenologia, desempenho produtivo, arquitetura de cacho e maturação tecnológica. Apesar de possuir adequada maturação tecnológica, a variedade Bordô apresentou baixa produtividade, sendo esta, a variedade avaliada de maior precocidade para brotação, floração e verásion, no entanto, na mesma data de colheita, a variedade Isabel Precoce apresenta maior acumulo de sólidos solúveis, além de destacar-se pela maior produtividade e bom índice de fertilidade. A maior compactação de cachos foi observada nas variedades Isabel Precoce e Concord, enquanto as demais variáveis de arquitetura de cacho apresentaram valores distintos entre as safras avaliadas.
“…Positive effects of GA 3 were observed in 'Sauvignon Blanc', 'Riesling', 'Lemberge' and 'Kadarka' cultivars, in the early ripening of grapes and in the high values of soluble solids, which is an important factor for the production of quality grapes and wines (TESZLAK et al, 2013). The application of GA 3 also promoted the increase of fresh and dry mass of 'Fujiminori' grapes (JUN et al, 2001) and improved the quality of 'Bordô' grapes, causing an increase in soluble solids content and a reduction in titratable acidity (CHIAROTTI et al, 2011). In 'Niagara' the application of GA 3 promotes the increase of berries mass, rachis mass and berry diameter (GUERIOS et al, 2016).…”
The ripening of grapes is impaired by climatic conditions due to the prolonged rainy season and thus facilitates the proliferation of diseases such as grape clusters rotting, caused by the fungus Botrytis cinerea, even before the ideal harvesting point. The aim of the study was to evaluate the effect of gibberellic acid (GA3) on rot and on physical-chemical quality of ‘Sauvignon Blanc’ grapevine. The experiment was carried out in the production season of 2016 and 2017 in Campanha region in Rio Grande do Sul, Brazil. The GA3 treatments were at the doses of 0 (control); 2; 4; 6 and 8 mg L-1 of GA3. The percentage of clusters rotting and maturation index decreased, however, the titratable acidity increased with GA3 doses. The cluster and rachis length increased with application of GA3. The cluster width; cluster, rachis and berry mass and the soluble solids were not influenced by application of GA3. In ‘Sauvignon Blanc’ grapevine, GA3 reduced the percentage of clusters rotting and improved the cluster and rachis length characteristics and titrable acidity.
