|Informações adicionais: ||The aim of this study was to develop a methodology for the vegetative propagation of paricá (Schizolobium amazonicum) through cutting, evaluating the effect of IBA (0, 8000, 16000 and 32,000 mg.L-1) on rooting of apical and intermediate stakes. The base of the cuttings were dipped in IBA solution for 10 seconds and then were staked in polyethylene tubes of 110 cm³, filled with organic substrate (Bioplant®). The irrigation of the seedlings was carried out by means of a nebulization system with a uniform flow rate of 7 L.h-1. After 40 days, were evaluated: percentage of survival, rooting percentage, percentage of roots observed at the lower end of the plastic tube, average number of roots, length of roots, presence of calluses, vigor and root dry matter. The results for the characteristics evaluated, with emphasis on survival, showed the highest averages were obtained at intermediate stakes, regardless of the dose of IBA. The highest rooting percentage, root number, length and dry mass of roots, in both types of cuttings was obtained with the highest dose tested of AIB (32,000 mg.L-1). Based on these results, it is concluded that the technique of cutting associated with application of plant growth regulators can be used for vegetative propagation of S. amazonicum.|
