Descrição: The aim of this paper was to verify the effect of different doses of gibberellic acid (GA3) (0, 250, 500, 750 and 1000 μg.L-1), of fungicides of the groups chemical benzimidazol (0, 25, 50 and 100 g.L-1) and ditiocarbamato (0, 1,25, 2,50 and 5,00 g.L-1) on seed germination. Viability of those seeds was evaluated through germination tests at 0, 15, 30 and 60 days. The experiment was carried out in greenhouse. The experimental design was fully randomized one, with five replicates per treatment. The traits evaluated were emergence and index of emergence speed. The treatment with GA3 didn t provide significant somuch differences among the germination rates as well as for the emergence speed. It was verified that the use of the fungicides in smaller concentrations (25 g.L-1 of benzimidazol and 1,25 g.L-1 of ditiocarbamato) promoted a better germination speed. The seeds of G. americana possess viability period relatively short, with germination absence 60 days period of storage, and it could be associated to the humidity tenors presented by the seeds in this period.
