Sumario:The objective of this research was to compare the efficiency of methods to suppress tegument impermeability on Leucaena diversifolia seeds. Seeds were collected in Botucatu, São Paulo State, Brazil, in May 2003, and allowed to dry in the shadow at room temperature. Samples taken from pure seed fraction were submitted to the following treatments: immersion in boiling water for one and two minutes; immersion in concentrated sulfuric acid (H2SO4) for one, three, and five minutes; immersion in H2SO4 diluted to 60% for five and ten minutes; and control (intact seeds). Germination tests indicated the concentrated H2SO4 for five inutes as the most efficient treatment. KEY-WORDS: Dormancy; Leucaena; germination.
