The cutting down of forests has caused the densities of C. guianensis to have decreased significantly in the Colombian Pacific. For this reason, the rooting of its cuttings was evaluated in response to the type of planting and the development phase. Cuttings were collected from branches with herbaceous, semi-woody and woody development phases. The harvested cuttings were immersed in ascorbic acid and preserved in moistened newspaper. Sowing was carried out in six germination beds; three using a substrate and three outdoors. The rooting substance was hormonegro 1 (0.05 g/stake). A randomized factorial design was used, composed of three factors (rooting hormone, planting site and cutting development phase). Monitoring was carried out every eight days. A rooting rate of 37.5 % was obtained, which was not significantly affected by the type of cutting used (herbaceous = 38.5 %, semi-woody = 32.3 and woody = 41.7 %), while the place of Sowing did have an effect on the rooting of the cuttings (organic substrate eras = 27.1 % and in- temperature soil = 47.9 %). It is concluded that cuttings from woody branches turn out to be the most suitable for the propagation of C. guianensis, because it experienced a better rooting response and survival in the evaluated treatments.
