Resumen en inglés

The present work was carried out in order to characterize the reproductive biology patterns of Caesalpinia ebano, endemic to the dry forests of Colombia. The study was carried out in the Jaguares de Montería ecological park in the department of Córdoba. Floral biology was described, different types of pollination were evaluated (induced self-pollination, cross-pollination, spontaneous self-pollination, open pollination) and the frequency of flower visitors was recorded. C. ebano presents hermaphrodite flowers with a length of 1.3 cm from the peduncle and an approximate average life span, from anthesis to dehiscence, of three days. The results obtained indicate that this species only produces fruits by cross pollination and open pollination, although in the induced self-pollination fruits were formed, all were aborted. According to the reproductive system that C. ebano presents, it is strictly dependent on pollinators for its reproductive success. The weight of the seeds and fruits were not significantly different between the treatments; however, there were significant differences regarding the number of seeds between the treatments. On the other hand, the floral visitor with the highest frequency of visits was A. mellifera.
