The tropical dry forest (bs-T) is one of the most threatened ecosystems on the planet, because of anthropic pressure. The subxerophytic enclave of the Chicamocha canyon is inhabited by Cavanillesia chicamochae, an endemic and threatened species that has little survival of its seedlings, affecting the regeneration of its populations. In the present study, the germination of C. chicamochae was evaluated with fruits, seeds, and cuttings, using three different substrates. Three treatments were used, which consisted of different substrates: T1: river sand; T2: black earth; T3: mix 3/4 soil -1/4 rice husk and fruits, bare seeds and cuttings were used. A completely randomized design was implemented with three substrates including fruits and seeds and four replicas were performed. The variables analyzed were subjected to an ANOVA, when the differences were significant (p < 0.05), in addition an analysis of means was developed using Duncan's multiple range test. The germination percentage per seed and fruit showed significant differences (p < 0.05), the treatment with the highest efficiency was T1 (71%-seeds and 54%-fruits). Seeds stored under ambient conditions lost their viability after four months. The mucilage presented an adequate bromatological value for the feeding of ruminants and important contents in secondary metabolites, with potential uses in the pharmaceutical area being an added value for the species. Water stress selects water conservation characteristics to guarantee the survival of species over time, a better understanding of these strategies will help predict responses to future droughts.
