Propagación vegetativa de dos especies carnívoras del género Drosera: análisis de métodos y eficiencia

Abstract

This research project focuses on identifying efficient methods of vegetative propagation for Drosera nidiformis and Drosera capensis, species maintained in the living collections of the José Celestino Mutis Botanical Garden. This genus of carnivorous plants is of great interest due to its biological uniqueness and ability to attract and digest insects. However, many carnivorous plant species are threatened by habitat loss, climate change, and overharvesting. Therefore, this project is essential for optimizing propagation and cultivation methods at the Bogotá Botanical Garden, enabling the institution to preserve and expand its collections while promoting conservation and knowledge of these fascinating plants. The study was carried out through controlled experiments, monitoring factors such as survival rate, development time, and the quality of propagated plants. Results showed that Treatment 3 (distilled water + aloe gel) achieved the best performance in terms of shoot production and leaf number. The most effective cutting type for propagating D. capensis was the leaf cutting, whereas for D. nidiformis the root cutting proved to be the most effective.
