Resumo: | Khaya ivorensis stands out because of the quality of the wood and high economic value. Its propagation has been carried out by seeds, an obstacle in the production in large scale, since the seeds present high value and they result in heterogenous stands. The vegetative propagation is inserted as an alternative to overcome these problems. The aim of this work was to verify the feasibility of minicutting for african mahogany, evaluating the productivity of the stock plants, the rooting of minicuttings using different concentrations of IBA and the clonal seedlings quality. The stock plants were produced from seeds in tubes, pruned at 8 cm, at 60 days. At 100 days after apical pruning, the first harvest of shoots was performed, in which the minicuttings were submitted to concentrations of IBA (0; 2000; 4000 and 6000 mg L-1) for rooting evaluation. The seedlings were transplanted to suspended sand beds, in which four harvests of minicuttings were performed. Clonal seedlings quality was evaluated at 120 days after staking. The species showed tolerance to apical pruning and successive harvests of minicuttings, with 96.4% survival and more than 92% of the stock plants has produced minicuttings. It was observed 100% survival and rooting of minicuttings. There was no effect of the AIB on the rooting percentage of the minicuttings, however, the higher concentration of AIB increase the thinner root production, 30 days after staking, however, there was no effect of the treatments on the of clonal seedlings quality. |
