Liana Abrus precatorius L. (Fabaceae) seeds were submitted to the following different treatments in order to break the tegument dormancy: T1) control; T2) mechanical scarification; T3) immersion in water at 80 oC for 5 minutes; T4) immersion in sulfuric acid for 15 minutes and T5) immersion in sulfuric acid for 30 minutes.
