This study was carried out at the Seed Laboratory of Embrapa Roraima, with the objective to study the alleviation of seed dormancy of the Paricarana tree (Bowdichia virgilioides). The experimental design was a completely randomized design with four replications of 50 seeds each. The treatments were: mechanic scarification with water sandpaper; sulfuric acid - pa (5 and 10 minutes), ethanol (5 and 10 minutes) and control. The seeds were placed in plastic boxes on moist paper and incubated at 25oC in a germinator. The parameters obtained were germination percentage, hard seed percentage, germination rate and percentage of normal seedlings at 30 days after sowing. The germinated seeds were counted daily for 30 days. Chemical scarification with sulfuric acid for 5 minutes was shown to be the most appropriate method for seed alleviation of this species.
