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.
