Resumo: | The objective of this work was to evaluate the influence of Trinexapaque-ethyl (TrixE) and benzyladenine (BA) on the fertility of buds and the quality of bunches of ‘Thompson Seedless’ grapes grafted onto ‘Ramsey’ rootstock, in the Vale São do Francisco. The experimental design consisted of randomized blocks with 16 treatments (doses and number of applications of the plant regulators TrixE and BA), with four replications, each composed of three plants, with one plant per plot. The variables analyzed were: overall potential bud fertility, potential of the basal, median and apical branches of the plant; fertility of potential buds from the basal region of the basal and median branches; fertility of overall real buds, and of the median and apical branches; diameter of the basal, median and apical branches; Falker chlorophyll index a, b and total; sprouting buds, number of clusters per branch, clusters per plant, branches per plant; berry diameter, length, volume; fresh material mass; soluble solids content (SS), titratable acidity (AT) and SS/AT relationship; diameter, length, mass of fresh material from the clusters; shatter, fresh material mass of the rachis and rachis diameter . It was shown that the TrixE applied in isolation , one, two or three times in doses of 20 mg L-1, or associated with BA in a single application of 120 or 240 mg L-1, increased the rate of real fertility, but did notaffect the length of the clusters or the vegetative vigor of the plants. |

O delineamento experimental adotado foi o de blocos ao acaso, com 16 tratamentos (doses e número de aplicações dos reguladores vegetais TrixE e BA), com quatro repetições, constituídas por três plantas, com uma planta útil por parcela. As variáveis analisadas foram: fertilidade de gemas potencial geral, potencial dos ramos basais, medianos e apicais da planta; fertilidade de gemas potencial da região basal dos ramos basais e medianos; fertilidade de gemas real geral, e dos ramos medianos e apicais; diâmetro dos ramos basais, medianos e apicais; índice de clorofila Falker a, b e total; brotação de gemas, número de cachos por ramo e por planta e de ramos por planta; diâmetro, comprimento e massa da matéria fresca e volume de bagas; e teor de sólidos solúveis (SS), acidez titulável (AT) e relação SS/AT; diâmetro, comprimento, massa da matéria fresca dos cachos; degrana, massa da matéria fresca do engaço e diâmetro do engaço. Verificou-se que o TrixE aplicado isoladamente, em uma, duas ou três vezes nas dosagens de 20 mg L-1, ou associado à BA em aplicação única de 120 ou 240 mg L-1 aumentou a taxa de fertilidade real, no entanto, sem afetar o comprimento dos cachos ou o vigor vegetativo das plantas.Universidade Federal Rural do Semi-Árido2016-12-02info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.ufersa.edu.br/caatinga/article/view/503810.1590/1983-21252017v30n111rcREVISTA CAATINGA; Vol. 30 No. 1 (2017); 97-108Revista Caatinga; v. 30 n. 1 (2017); 97-1081983-21250100-316Xreponame:Revista Caatingainstname:Universidade Federal Rural do Semi-Árido (UFERSA)instacron:UFERSAenghttps://periodicos.ufersa.edu.br/caatinga/article/view/5038/pdfVilar, Patrícia Fernanda InácioSouza, Eder Ignácio deSantos, Laise de SousaMartinez, Emanuel AlmeidaRibeiro, Valtemir Gonçalvesinfo:eu-repo/semantics/openAccess2023-07-20T10:37:24Zoai:ojs.periodicos.ufersa.edu.br:article/5038Revistahttps://periodicos.ufersa.edu.br/index.php/caatinga/indexPUBhttps://periodicos.ufersa.edu.br/index.php/caatinga/oaipatricio@ufersa.edu.br|| caatinga@ufersa.edu.br1983-21250100-316Xopendoar:2024-04-29T09:46:20.694896Revista Caatinga - Universidade Federal Rural do Semi-Árido (UFERSA)true |
