Abstract: Amburana cearensis (allemão) A. C. Sm. belongs to the Fabaceae family and is primarily used in folk medicine due to its abundance of medicinal compounds, making it a viable option for mixed planting schemes not solely focused on timber exploitation.Its propagation via mini-cuttings could facilitate the multiplication of selected individuals based on desirable traits.However, the rooting percentage of mini-cuttings for this species is low.Thus, this study aimed to evaluate the rooting of mini-cuttings of A. cearensis collected from different positions on the shoots (basal, intermediate, and apical) and subjected to treatments with IBA (0, 2000, 4000, 6000, and 8000 mg L -1 ), with or without the application of H 2 O 2 (50 mM).Despite the higher survival rate of basal mini-cuttings, the position of the cuttings did not positively affect the other characteristics of the produced seedlings, except for the dry root mass.At 60 days after planting, the isolated treatments of H 2 O 2 and IBA at a concentration of 2000 mg L -1 resulted in high survival rates of A. cearensis mini-cuttings (> 80%), but did not improve the rooting percentage, which remained below 50%.
