Resumo: The present study was undertaken to evaluate the Ethephon effect on the vegetative and reprodutive development of watermelon plants 32 days after sowing. The experiment was conducted under field conditions in Anhembi, SP, Brazil. Plants with 6 leaves were treated with an ethephon water solution of 0, 400, 800, 1600 or 2400 mg.L-1, plus Extravon 0.05% (alquil phenol poliglicoleter). The applications were made in the morning, with air RH (%) 50-60 and temperature less than 30ºC. The results showed that 7 days after application (DAT), Ethephon affected the development of lateral shoots at the concentrations of 800, 1600 and 2400 mg.L-1, delaying the appearance of male and female flowers, and the highest concentration promoted shoot apex death. At 28 D.A.T., plants showed new lateral shoots, including the appearance of male and female flowers, in lower numbers as compared to the control. The lowest concentration promoted a delay in flowering and in the development cycle, but had a good commercial yield. The other concentrations did not present any commercial yield.

Plantas com 6 folhas definitivas foram pulverizadas com solução aquosa de ethephon nas concentrações de 0, 400, 800, 1600 e 2400 mg.L-1 adicionadas de Alquil fenol poliglicoleter a 0,05%. As aplicações foram realizadas pela manhã em condições de UR = 50-60% e temperatura menor que 30ºC. Observou-se que 7 dias após a aplicação, o ethephon nas dosagens de 800, 1600 e 2400 mg.L-1 afetou o desenvolvimento das brotações laterais e inibiu a formação de flores masculinas e femininas. A concentração de 2400mg.L-1 promoveu morte do ápice e encarquilhamento foliar. Porém, 28 dias após a aplicação, houve surgimento de novas brotações laterais e o aparecimento de flores masculinas e algumas flores femininas, porém em menor número em relação à testemunha. A aplicação de ethephon nas concentrações testadas promoveu atraso no florescimento e no ciclo total de desenvolvimento, porém, sob menor concentração houve produção de frutos comerciáveis, enquanto que sob maiores concentrações, não. Nenhuma das concentrações testadas provocou a morte das plantas.Universidade Federal de Santa Catarina2000-01-01info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.ufsc.br/index.php/biotemas/article/view/22344Biotemas; v. 13 n. 2 (2000); 55-632175-79250103-1643reponame:Biotemas (Online)instname:Universidade Federal de Santa Catarina (UFSC)instacron:UFSCporhttps://periodicos.ufsc.br/index.php/biotemas/article/view/22344/20283Copyright (c) 2000 Marcio Christian Serpa Domingues, Elizabeth Orika Ono, João Domingos Rodrigueshttp://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccessDomingues, Marcio Christian SerpaOno, Elizabeth OrikaRodrigues, João Domingos2022-11-18T13:26:29Zoai:periodicos.ufsc.br:article/22344Revistahttp://www.biotemas.ufsc.br/index.htmPUBhttps://periodicos.ufsc.br/index.php/biotemas/oai||carlospinto@ccb.ufsc.br2175-79250103-1643opendoar:2022-11-18T13:26:29Biotemas (Online) - Universidade Federal de Santa Catarina (UFSC)false
