Propagación asexual de especies endémicas y amenazadas del género Passiflora en los Andes colombianos.

The Passiflora genus has a large representativeness in Colombia and includes endemic and threatened species distributed mainly in the Andes. It is necessary to promote knowledge of these species and appropriate practices for their conservation because they represent valuable sources of germplasm. We evaluated the effect of a natural and a synthetic treatment on the performance of stakes of five endemics and threatened species of Passiflora from the Colombian Andes. Both treatments promoted the production of roots and the synthetic treatment had the highest values and a lower mortality. The response of the stakes was different among the five species and the measured variables had different values for each one during the development after sowing. Both treatments improve the root development of Passiflora stakes, although the synthetic treatment had advantages over the natural one; however, its use must be oriented to the development characteristics of each species.
