Summary: | The objective of this work was to evaluate the effect of grapevine (Vitis vinifera L.) summer pruning on Merlot wine composition. An experiment was carried out from 1993/1994 to 1996/1997 in Bento Gonçalves, RS, Brazil, using a control and 11 summer pruning in grapevines trained in pergola system. Principal component analysis showed that the summer pruning effects varied by year. Considering the average of the four years, the first three principal components were responsible for 72% of the total variation. Sprouting, topping, and removal of all leaves below grapevine clusters at the beginning of bloom had high values of color intensity, absorbances at 280 and 520 nm, anthocyanins, tannins, alcohol, 3-methyl-1-butanol/2-methyl-1-propanol, alcohol in weight/reduced dry extract, and phosphorus and was the best alternative for the production of quality Merlot wine. |

Um experimento foi conduzido de 1993/1994 a 1996/1997, em Bento Gonçalves, RS, com uma testemunha e 11 modalidades de poda verde em vinhedo conduzido em latada. A análise de componentes principais mostrou que o efeito da poda verde variou conforme o ano. Considerando a média dos quatro anos avaliados, os três principais componentes foram responsáveis por 72% da variação total. A desbrota, desponta e desfolha realizada no início da floração, com eliminação de todas as folhas abaixo dos cachos foi a modalidade de poda que apresentou os valores mais elevados de intensidade de cor, absorbâncias a 280 e 520 nm, antocianinas, taninos, álcool, 3-metil-1-butanol/2-metil-1-propanol, álcool em peso/extrato seco reduzido e fósforo, e foi a mais indicada para a produção de vinho Merlot.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraMiele, AlbertoRizzon, Luiz AntenorMandelli, Francisco2010-11-18info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/1771Pesquisa Agropecuaria Brasileira; v.44, n.5, maio 2009; 463-470Pesquisa Agropecuária Brasileira; v.44, n.5, maio 2009; 463-4701678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/1771/5715https://seer.sct.embrapa.br/index.php/pab/article/downloadSuppFile/1771/1184https://seer.sct.embrapa.br/index.php/pab/article/downloadSuppFile/1771/1185info:eu-repo/semantics/openAccess2012-06-17T11:49:50Zoai:ojs.seer.sct.embrapa.br:article/1771Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2012-06-17T11:49:50Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false |
