FLORÍSTICA E SÍNDROMES DE DISPERSÃO DE UM FRAGMENTO DE CERRADO AO SUL DO ESTADO DO TOCANTINS.

The plants have adaptations according to the dispersion agent and are directly related to the morphological characteristics of the species and the region of occurrence. Considering the lack of information on the vegetation of Tocantins, the objective was to identify the floristic composition and the dispersion syndromes in a fragment of cerrado stricto sensu in the municipality of Cariri, Tocantins, Brazil, in order to identify the main type of dispersion in this forest fragment And evaluate if the size of the trees is related to the form of dispersion. Sampled to total area of 2.75 ha, divided into 55 sampling units (10 x 50 m) from which were species classified According to dispersion syndrome and peculiar and catches. In this study were recorded in 2654 Individuals and identified 81 species, in which 51.5% of subjects in zoochorous dispersion syndrome, 39.6% anemocorous and 6.4% in autochorous. It is concluded that the zoocoric species are dominant in this fragment of cerrado, being important for the maintenance of the flora because there is interdependence between plants and animals and presents, generally, high representativity independently of sized trees emphasizing that the syndromes of dispersion have no relation with the sized trees, but with physiognomy.
