The objective of this study was to evaluate the in vitro germination of beetroot seeds, cv. Early Wonder Tall Top, treated with gibberellic acid and sucrose at different concentrations. A randomized complete block design in a 2 x 5 factorial arrangement with five replications was used. The beetroot seeds ware pre-soaked in gibberellic acid (GA3) and destilated water  during six hours, maintained of five concentration of culture medium (0, 15, 30, 45, 60 g L-1). Seeds treated with GA3 and maintained in medium with sucrose in the concentrations of 15 g L-1 presented the highest germination, while seedlings with the highest vigor were obtained with seeds maintained in the medium at 15 and 30 g L-1 of saccharose.<p><p>O objetivo deste trabalho foi avaliar a germinação in vitro de sementes de beterraba, cv. Early Wonder Tall Top, tratadas com ácido giberélico em diferentes concentrações de sacarose no meio de cultura. Utilizou-se o delineamento em blocos casualizados, em um esquema fatorial 2 x 5, com cinco repetições. Os tratamentos foram sementes pré-embebidas em ácido giberélico (GA3) e sementes pré-embebidas em água destilada por seis horas, mantidas em cinco concentrações de sacarose no meio de cultura (0; 15; 30; 45; e 60 g L-1). Sementes tratadas com GA3, mantidas no meio de cultura com sacarose na concentração de 15 g L-1, apresentam maior porcentagem de germinação, enquanto plântulas mais vigorosas foram obtidas a partir de sementes mantidas nos meios suplementados com 15 e 30 g L-1 de sacarose
