Conteúdo: 	The flowering phenology, pollination biology and breeding systems of tree species  were studied  in a 40 h area of cerrado vegetation in central Brazil. The cerrados are Neotropical savanna plant formations in central Brazil. They represent the second most important vegetation province in Brazil and are nowadays the main agricultural frontier which has resulted in deforestation rates much higher than those occurring in lowland   tropical forest. Despite the marked winter/dry - summer/wet seasonality, defferent   species werw encountered in flower throughout the year, althogh wit a peak at the dry season. Seven pollination guilds were identifid, renging from very small insects (boody size less than 5 mm) to bast, but bee pollination was         predominant, and overall pollination biology of the cerrado community was similar to that reported for evergreen neotropicalforest. Mst species were ourbreeding in that self-pollinations yielded very fruits, but heteromorphic and homomorphic self-incompatibility were rare and control of selfing was commonly exercised by ill-defined post-zygotic mechanisms. The results indicated that reproductive biology of wood cerrado species is not markedly different fron other tropical forest communities and suggestes adaptation to seasonal habitats did not always lead to simplification or changes in breeding features of the cerrado species.
