Resumo: The present work aims to identify the vegetal regulators and optimum dose to reduce plant height and layering and their influence on production and productivity components in sprinkler-irrigated highland rice grains. Treatments consisted of three vegetal regulators and four doses. Mepiquat chloride (Pix) and ethyl-trinexapac (Moddus) were applied at doses of 0, 2000, 4000 and 8000 mg L-1, while paclobutrazol (Paclobutrazol) was applied at 0, 1000, 2000 and 4000 mg L-1, commercial product. The vegetal regulators were applied during the profiling state, utilizing Primavera cultivar. Results showed that ethyl-trinexapac reduced the plant height and influenced negatively grain production and productivity components. No optimum dose was identified to reduce plant height and increase grain productivity.

Os tratamentos foram constituídos de três reguladores vegetais e quatro doses. O cloreto de mepiquat (PIX) e o etil-trinexapac (Moddus) foram aplicados nas doses 0, 2000, 4000 e 8000 mg L-1 e o paclobutrazol (Paclobutrazol ou Cultar) foi aplicado nas doses 0, 1000, 2000 e 4000 mg L-1, do produto comercial. Os reguladores vegetais foram aplicados no estádio de perfilhamento, utilizando o cultivar Primavera. Constatou-se que a aplicação do etil-trinexapac reduziu a altura da planta e influenciou negativamente os componentes da produção e produtividade de grãos.Universidade Estadual de Maringá2007-11-01info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttp://www.periodicos.uem.br/ojs/index.php/ActaSciAgron/article/view/25810.4025/actasciagron.v29i2.258Acta Scientiarum.
