Evaluación de técnicas de propagación en algunas especies de plantas de interés para la restauración de la reserva umbral cultural horizontes en Bogotá, Colombia

Abstract

The propagation of plant species focused on ecological restoration has been a widely studied topic over the last years, however, it represents an extensive field of study that still has much to be investigated. In the present work, the propagation methods of nursery and in vitro sowing were evaluated for the species Bejaria resionosa and Hypericum juniperinum, responding to the need of plant material for the recovery of the Natural Reserve of the Umbral Cultural Horizontes Civil Society. Sowing was carried out in different substrates for nursery planting. For in vitro planting, a written protocol was replicated for Hypericum juniperinum species and three different media were compared for Bejaria resionosa species. The results show the need for pre-germinative treatments for both species in nursery sowing, as well as the need for a cooling period of the seeds prior to in vitro sowing for Hypericum juniperinum species. In addition, an efficient protocol for the in vitro propagation of Bejaria resinosa species is established, with 90% germination.
