The objective was to identify the proportion of seed dispersion syndromes in areas of cerrado sensu stricto of Central Brazil and amazonian savannas. Lists of species of nine cerrado and five amazonian savanna areas were used. Dispersion syndromes were determined through literature data. Chi-square test (chi²) was used to evaluate possible differences in proportion of zoocory and anemocory among cerrado sensu stricto of Central Brazil and among amazonian savanna areas. Floristic similarity was determined among the 14 areas. The averages of these proportions were compared through t test and no significant differences were found (p > 0.05). The proportion of zoocory species in cerrado sensu stricto and amazonian savannas were 56.7% ± 5.4 DP and 55.6% ± 11.7 DP; the proportion of anemocory were 39.7% ± 6.2 DP and 44.4% ± 11.7 DP, respectively. In the cerrado sensu stricto of Central Brazil the proportion of autocory ranged from 1.4 to 5%, while the amazonian savannas presented no autocoric species. Autocory is a rarely found strategy in cerrado sensu stricto and its absence in amazonian savanna areas could be related to the low efficiency in colonization of isolated areas.
