Resumo: | The experiment was conducted during the vegetative cycle of 1978/79 with 'Isabel' grapevines (Vitis labrusca L.). The clusters were dipped into gibberellic acid (GA3) solutions, in prebloom or bloom time, in the concentrations of 0, 10, 50, 100, and 200 ppm. At postbloom time concentrations of 0, 50, and 100 ppm, of GA3 were utilized. Combined treatments were still done in prebloom plus postbloom and in bloom plus postbloom. The application of GA3 in the stages of prebloom, bloom or postbloom increased the percentage of total seedless berries per cluster due to the development of normal seedless berries and small berries. This effect was greater in combined applications, in prebloom plus postbloom and with the highest concentration. All treatments reduced the seed number per normal berry. GA3 decreased the weight per cluster when applied in prebloom or in the bloom time and increased it when applied in the postbloom. |

Isabel. Os cachos foram imersos em soluções de ácido giberélico (AG3), nas concentrações de 0, 10, 50, 100 e 200 ppm, em pré-floração ou na floração. Em pós-floração foram utilizadas concentrações de 0, 50 e 100 ppm. Também foram feitos tratamentos combinados em pré-floração mais pós-floração e na floração mais pós-floração. A aplicação de AG3 no estádio de pré-floração, floração ou pós-floração aumentou a percentagem total de bagas sem sementes por cacho, em virtude do desenvolvimento de bagas normais sem sementes e de bagas pequenas. Esse efeito foi maior nas aplicações combinadas, em pré-floração mais pós-floração, e com o emprego das mais altas concentrações. Em todos os tratamentos houve redução do número de sementes por baga normal. O AG3 reduziu o peso por cacho, quando aplicado em pré-floração ou na floração, e o aumentou quando aplicado em pós-floração.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraTonietto, JorgeMiele, AlbertoJunior, Paulo Silveira2014-04-16info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/15244Pesquisa Agropecuaria Brasileira; v.18, n.4, abr. 1983; 381-386Pesquisa Agropecuária Brasileira; v.18, n.4, abr. 1983; 381-3861678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/15244/9074info:eu-repo/semantics/openAccess2014-04-16T18:54:04Zoai:ojs.seer.sct.embrapa.br:article/15244Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2014-04-16T18:54:04Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false |
