Abstract
Flamboyant has great ornamental use, because it has beautiful flowers, having a great use in urban afforestation and park ornamentation. The seeds have a low germination rate because they have dormancy caused by the impermeability of the integument. In this sense, the objective was to determine the most efficient method to overcome dormancy in flamboyant seeds. The experimental design was fully randomized with 4 treatments and 3 replications. The treatments consisted of: 1-Witness (non-scarified seeds); 2- Hot water at 90º C for 5 minutes; 3- Concentrated sulfuric acid 98% for 60 minutes; 4- Mechanical scarification with sandpaper number 80. The characteristics evaluated were: emergency, emergency speed index, seedling height and root length. A significant difference can be observed in the treatments evaluated only for the emergency speed index where the scarification treatment with sandpaper was higher than the others, for the other characteristics evaluated there was no difference
