Summary: | Abstract 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.
Resumo O crescimento das atividades do turismo rural tem levado os viticultores a utilizarem diferentes cultivares de uva para elaboração de vinho e/ou suco. Nesse sentido, objetivou-se avaliar as características fitotécnicas das videiras e físico-químicas do mosto das cultivares Bordô, Isabel Precoce, BRS Violeta, Isabel e Concord, em diferentes sistemas de sustentação: espaldeira; manjedoura na forma de Y e manjedoura na forma de V com cordão esporonado duplo. O delineamento experimental foi em blocos ao acaso para a comparação das cultivares, dentro de cada sistema de sustentação, e foi realizada análise dos componentes principais para as variáveis da produção. A cultivar BRS Violeta apresentou maior massa de cacho, independentemente do sistema de sustentação das videiras. A cultivar Bordô foi a menos produtiva e com menor teor de sólidos solúveis, em comparação com as outras cultivares. As cultivares Isabel e Isabel Precoce, nos sistemas de sustentação avaliados, apresentaram maior teor de sólidos solúveis. A análise de componentes principais permitiu verificar que os sistemas manjedoura na forma de Y e V com cordão esporonado duplo foram associados a maiores produtividades. |
