ABSTRACT
Aiming to evaluate the effects of doses and time of application of different growth regulators on sweetsorghum and its influence on plant development and germination of seeds produced, an experiment in a greenhousewas set up in September 2011, in Sete Lagoas, MG, Brazil, at Embrapa Maize and Sorghum, with three commercialactive ingredients (trinexapaque-ethyl, paclobutrazol and daminozide), six doses for each product and two applicationtimes throughout the cycle. It was observed that the active ingredient Trinexapaque-ethyl was the most effective inreducing the height of sweet sorghum when applied twice during the crop cycle, but it promoted serious damage onseed quality.
