This work shows different dormancy breaking treatments of *Annona muricata L. **seeds (graviola). Five types of treatment were performed to the seeds, as follows: scarification (TT1); heated water at 60°C for fifteen minutes (TT2), and heated water at 60°C for five minutes (TT3); sulfuric acid for five minutes (TT4); and the control treatment (TT5), when the seeds did not receive any ***previous
treatment. The best result was achieved with the water being heated at 60° for five minutes (TT3).
