Resumo. This study aimed to evaluate the effects of different concentrations of the indolbutiric acid and α-naphthalene acetic acid on the rooting of semi-woody cuttings, collected from the sprout of Cordia trichotoma seedlings. Seedlings were produced by seeds constituting a miniclonal garden with subsequent pruning of the aerial part. Sprouts were harvested resulting in semi-woody cuttings with 12.0 cm long and 5.5 mm in diameter and a pair of leaves in the apical portion reduced in a half. The treatments consisted of fast immersion of the cuttings base in indolbutiric acid (IBA) and α-naphthalene acetic acid (NAA) in concentrations of 0, 2.000, 4.000, 6.000, 8.000 mg L-1 in a randomized block design with bifactorial arrangement 2 x 5. After 60 days of cutting, rooting percentage, roots number and length, sprouting percentage, the number of shoots and new leaves were evaluated as well as the survival and mortality. The phytoregulator IBA at a concentration of 8.000 mg L-1 promoted greater rooting, resulting in 28.9% of the cutting rootings, and greater number of roots per cutting. For the NAA, there was no significant effect on rooting. The increasing concentration of phytoregulators linearly reduced the emission of new leaves and shoots, and increased linearly cutting mortality, negatively affecting the components of the shoot of semi-woody cuttings of Cordia trichotoma.
