Ensayos de propagación de algunas especies forestales aptas para el manejo de la microcuenca La Lejía, Cundinamarca, Colombia
Cundinamarca, La Lejía Microbasin, Propagation of forest species
Propagation trials were conducted on 13 tree spe- cies considered in previous studies as a suitable for rehabilitation of the La Lejiamicrobasin in Cun- dinamarca, Colombia. Studied species were Gua- dua angustifolia (guadua), Trichanthera gigantea (madre de agua), Tabebuia rosea (ocobo), Cordia alliodora (nogal cafetero), Croton spp (drago), Erythrina edulis (balú), Persea americana (agua- cate), Cedrela montana (cedro de altura), Cedrela odorata(cedro rosado), Ficus spp (caucho), Ficus carica (brevo), Psidium guajava (guayaba) and So- lanum betaceum (tomate de árbol). In three com- munity nurseries we evaluated the response of seeds, rescued seedlings and hardwood cuttings in five substrate types (i.e. 1. soil, 2. soil and organic fertilizer, 3. soil and rice husk, 4. soil and a mi- crobial mixture, and 5. all types combined). Spe- cies response was measured during three months in terms of germination/survival percentage and changes in leaf number and seedling height. The re- sults showed that survival and growth were signifi- cantly higher in soil and organic fertilizer and soil and rice husk for any propagation type. The best performance was exhibited by Cedrela Montana and Erythrinaedulis. We highlight the importance of community nurseries for successful monitoring and implementation of propagation strategies of valuable tree species for local communities.
