Abstract

Cheilocostus speciosus plants are important ornamental plant that has been cultivated as a cut flower. This species is propagated by cuttings, but no studies on the factors that influence this process. Therefore, the main of this work was to study the effect of the indolebutyric acid (IBA) on the rooting of cuttings of Cheilocostus speciosus. The experiments were carried out University State de Mato Grosso, Campus of Cáceres/MT. The experimental design was completely randomized and the treatments six IBA concentrations (0, 200, 400, 600, 800 e 1000 mg L^-1), four replicates of 10 cuttings per replicate. The variables were observed: percentage of rooting, dead cuttings percentage, number of roots, length of roots, number of piles with bud, percentage of root callus. The indolebutyric acid concentration of 720 mg L^-1 increased the rooting percentage, and the 685 mg L^-1 one increased root number.
