1er. Resumen:A study of the fruit and seed production was undertaken for three woody savanna species: Byrsonima crassifolia, Palicourea rigida and Bowdichia virgiliodes. Mean fruit production per tree was greater in B. crassifolia with low incidence of predispersal predation, followed by B. virgiliodes with a high proportion of predated seeds and finally, P. rigida with comparatively low incidence of seed predation. Our results indicate that the studied species produce a great quantity of viables propagules and that although annual seedling recruitment is low, sexual reproduction may play an important role in the establishment of their populations. Resprousting after fire is playing a major role in plant growth and survival.
