| description | Introduction: Dalbergia congestiflora Pittier (campincerán) is used to make musical instruments in Michoacán (Mexico), so this specie is considered overexploited and at risk of extinction. Propagation studies of campincerán are scarce, but the factors that could affect the propagation by stem cuttings of this species are auxin exogenous concentration and position of the stem cuttings (apical, media and basal). The hypothesis tested is that a higher sprouting and rooting at concentrations between 1 and 10 ppm of indolbutyric acid (IBA) and the basal stem cuttings are observed. Method: The stem cuttings of D. congestiflora were collected in Tacámbaro, Michoacán. The apical, middle and basal cuttings were placed in a rooting solution of 1, 5 and 10 ppm of IBA. The variables studied were the sprouting percentage, the mean number of sprouts and the mean length of the sprouts after 15, 45 and 75 days, while the percentage of rooting was evaluated after 150 days. Results: The sprouting percentage, mean number of sprouts and mean length of sprouts were higher in basal cuttings in relation to the apical and meddle cuttings. The rooting was observed only at basal cuttings with 10 ppm of IBA. Conclusion: The sprouting of cuttings was observed at low cocentrations of IBA and this is independent of position stem cuttings, but the rooting occurred only at 10 ppm of IBA. |
