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.
