    The Passiflora genus presents a representative variability of species within the inter-Andean alley, however, the difficulty of propagation and the limited availability of studies, have caused a lack of interest in this genus; In this research the following objectives were proposed: 1) To evaluate the effect of different concentrations of 2 hormones on the rooting of cuttings of 4 species of Passiflora identified in the foothills of the Andean forest of the parishes of Chumblin and San Gerardo. 2) To evaluate the effect of two hormones, naphthaleneacetic acid (NAA) and indole butyric acid (IBA) on the rooting of cuttings in field conditions in four species (Passiflora ampullaceae, Passiflora manicata, Passiflora tripartita, Passiflora ligularis). 3) To evaluate three concentration doses of ANA (100, 200 and 300 ppm) and AIB (250, 500 and 750 ppm), for rooting cuttings of 4 species of Passifloras. An independent experiment was carried out, each one was developed with a completely randomized design with 7 treatments and 8 replicates. The results showed that, for the number of live cuttings, P. ampullaceae, presented a survival percentage of 50% in (500 and 750 ppm) of AIB, in the number of buds, differences were presented in P. manicata, being ANA (200 ppm) the best treatment; for the number of roots, AIB in (500 and 750 ppm) presented categories of abundant and regular, for root length, values of 2.8 cm were reached with the use of ANA (100 ppm). The present work concludes that each species responds differently to the treatments.
