Resumo: | The experiment was carried out in a commercial orchard of ‘Ponkan’ mandarin (Citrus reticulata Blanco), grafted on ‘Cleopatra’ mandarin (Citrus reshni Hort. ex Tan.), in Pratânia, state of São Paulo, Brazil. The utilized experimental design was composed of randomized blocks of four replications. The treatments consisted of: 0 (control), 5, 10, 15 and 20 mg L1 of Gibberellic acid (GA3). Atomizer equipment was utilized for the application of the treatments. Each plant received 5.9 liters of solution, in which 0.03% of nonionic surfactant with 25% of alkylphenol ethoxylate was added, in order to change fruit coloration. The analyses of fruit quality were developed on the 13th, 45th, 75th and 111th days after the application of the treatments (DAT). Results showed that the application of GA3 did not affect fruit fresh mass, total soluble solids content, total titulable acidity and ratio. However, a delay in fruit harvesting was verified, which was induced by the physiological effect of Gibberellic acid. |

Adotouse o delineamento experimental em blocos casualizados com 4 repetições. Os tratamentos empregados foram: 0 (controle), 5, 10, 15 e 20 mg L1 de ácido giberélico (GA3). A aplicação dos tratamentos foi realizada com atomizador tratorizado. Na mudança de coloração dos frutos, utilizaramse 5,9 litros de solução por planta, com adição de 0,03% de surfatante não iônico com 25% de Alquil fenol poliglicoléter. As análises da qualidade dos frutos foram realizadas aos 13, 45, 75 e 111 dias após a aplicação dos tratamentos (DAT). Não se verificou influência da aplicação de GA3 na massa fresca dos frutos, no conteúdo de sólidos solúveis totais, na acidez total titulável e “ratio”. No entanto foi observado atraso na colheita de frutos, induzido pelo efeito fisiológico do ácido giberélico.Universidade Estadual de Maringá2008-04-04info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttp://www.periodicos.uem.br/ojs/index.php/ActaSciAgron/article/view/129710.4025/actasciagron.v28i1.1297Acta Scientiarum.
