Conteúdo: 	Because of the economic importance of Peltophorum dubium, the aim of this work was to determine the best treatment to release mechanical dormancy and light impact on the germinative process. Four replicates of 50 seeds were used for each treatment and germination was carried out on sterilized Petri dishes covered with autoclaved filter paper moistened with Captan solution (0.2%). P dubium sedes exhibit a mechanical dormancy, and the best treatment to promete the highest rate (0,39 days-¹) and percentage (60.8%) without embryo damage is chemical scarification with sulfuric acid during 20 minutes. Different light conditions (darkness, white, red and far red) and intensities (0,25, 50 and 75% of shading) did not produce significant differences (P<0.05) on rate and germinability.
