The objective is to evaluate the germination potential and cutting technique of Aegiphila brachiata (peloteiro), as well as the age influence of the mother plant and the indolebutyric acid and Azospirillum brasilense use on adventitious rooting influence. Thus, was performed the physical characterization of the seed lot and then the germination test, with and without seed scarification and with three gibberellin concentrations (0, 50 and 100 mg L-1 GA3) (Experiment I). For cutting, two experiments were carried out with cuttings coming from young (Experiment II) and adult (Experiment III) trees. For both experiments, the cuttings were submitted to treatments with indolebutyric acid (0, 1500, 3000 and 6000 mg L-1) and solution composed of Azospirillum brasilense (50% and 100%), kept in a greenhouse for 30 days. There was no germination of any seed, and was identified a barrier in the endocarp to the radicle emission. The cutting technique by cuttings from young trees is recommended for seedling production of the species (53.75% rooting), requiring application of 6000 mg L-1 IBA. The Azospirillum brasilense use was not efficient at the root induction. Cuttings from adult trees are not recommended for peloteiro (Aegiphila brachiata Vell.) seedling production due the low rooting rates (10%) and high mortality (68.33%).
