          Abstract

          A natural vegetation area, with 1269 ha, composed mainly by cerrado, located at Santa Rita do Passa Quatro Municipality, São Paulo State, southeastern Brazil (21°36-39'S, 47°36-38'W), was studied. From September 1995 to February 1997, a floristic survey was carried out, when all vascular plant species at reproductive stage were collected. The flowering and fruiting patterns of the community were studied, comparing the herbaceous and the woody species. In the herbaceous component, 239 species were found and, in the woody one, 108 species. The woody species flowered mainly at the beginning of the rainy season, while the herbaceous ones produced flowers generally at the end of that season. The proportion of anemo and autochorous species was greater in the herbaceous component. The zoochorous ones, on the contrary, were more frequent in the woody component. At the dry season, when their dispersion is more efficient, the proportion of anemo and autochorous species producing fruits was higher. During the rainy season, when their fruits become attractive for longer time, the zoochorous species fruited more intensely.

          Foi estudada uma área de vegetação natural, de 1269 ha, composta principalmente por cerrado, situada no munícipio de Santa Rita do Passa Quatro, estado de São Paulo (21°36-39'S, 47°36-38'W). Entre setembro de 1995 e fevereiro de 1997, realizou-se um levantamento florístico, em que foram amostradas as espécies vasculares de plantas em fase fértil. A partir dos dados desse levantamento, estudaram-se os padrões de floração e frutificação da comunidade, comparando as espécies herbáceo-subarbustivas com as arbustivo-arbóreas. No componente herbáceo-subarbustivo, foram encontradas 239 espécies e, no componente arbustivo-arbóreo, 108 espécies. As espécies arbustivo-arbóreas floresceram principalmente no início da estação chuvosa, enquanto as herbáceo-subarbustivas produziram flores, de modo geral, apenas no final da estação úmida. A proporção de espécies anemo e autocóricas foi maior no componente herbáceo-subarbustivo, ao contrário das zoocóricas, mais freqüentes no componente arbustivo-arbóreo. Na estação seca, quando sua dispersão é mais eficiente, a proporção de espécies anemo e autocóricas em frutificação foi maior. Já durante a estação chuvosa, as espécies zoocóricas frutificaram com maior intensidade, uma vez que seus frutos carnosos podem se manter atraentes por mais tempo.
