local.description.resumoKhaya anthotheca is a hardwood species from Africa and recently introduced to Brazil. This species yields high-quality wood for diverse applications, but little has been done toward an effective propagation method for large-scale production in nurseries. We evaluated the effects of different concentrations of macro and micronutrients (i.e., 100, 50 and 25% of the concentration of a referenced solution) combined with indole-3-butyric acid (IBA) at 0 and 2 g L-1 on the survival rate of mini-stumps and the survival and adventitious rooting of K. anthotheca mini-cuttings. The mini-stumps were grown from a source of seeds imported from Ghana, West Africa. The mini-stumps survived at a high rate (97%). Consistently high shoot yields were obtained from the mini-stumps (average of 1.8 per mini-stump). High survival percentage of mini-cuttings and adventitious rooting were observed when solutions with 100 and 50% of the nutrients concentration were combined with 2 g L-1 IBA. Histological sections analyzed through optical microscopy indicated the tissues from mini-cutting stems were juvenile, which might have stimulated adventitious rooting. These results have important implications for further work aimed at estab- lishing propagation strategies for K. anthotheca, which are of prime importance for assisting breeding programs of this species.
