Aegiphila brachiata Vell. (Lamiaceae), known as peloteiro, is a shrub-tree species native to Mata Atlântica from the southern region of Brazil, with potential use for reforestation degraded areas, as food and medicinal plant. However, there are few studies that elucidate its propagation, both sexual asexual. In this study, we seek elaborate protocol vegetative propagation by cuttings A. brachiata. For this, two experiments were installed: herbaceous (Experiment I) semi-hard II). The material was collected 20 adult trees in Bocaiuva do Sul (Parana, Brazil). Both seasons: spring (October/2019) summer (January/2020). treated different concentrations indole butyric acid (IBA) (0 mg L-1; 3000 6000 9000 12000 L-1) maintained during 60 days green house. variables analyzed were: percentage rooted cuttings, number length three longer roots per cutting, alive, callus, dead, buds maintenance leaves. On Experiment I, survival rate 20%. A significant difference observed seasons callus formation, higher (17.7% against 4,3% spring). application IBA, under studied conditions, did not lead any variables. II showed 100% mortality. Therefore, it possible determine viable cutting due low rooting rate.
