RESUMO


(Chuva de sementes em uma área de vegetação de Caatinga no estado de Pernambuco) Este estudo descreve
a composição e a densidade da chuva de sementes em um hectare de vegetação de Caatinga. Quarenta
coletores de semente, de 0,25 m2 cada, foram instalados e visitados mensalmente por um ano. Foram depositadas
76 sementes/m2 e 26 espécies. Os indivíduos de Tillandsia spp. (Bromeliaceae) contribuíram com a maioria
(49%) das sementes. Não houve correlação estatística entre a densidade de deposição de sementes e a
precipitação mensal. A autocoria prevaleceu nas sementes de plantas lenhosas (árvores e arbustos).

Palavras-chave: semi-árido, síndromes de dispersão, sazonalidade.</abstract>

ABSTRACT

(Seed rain in an area of Caatinga vegetation in Pernambuco State) The current study describes the composition
and density of seed rain in one hectare of Caatinga vegetation. Forty seed traps of 0.25 m2 each were set, and
visited monthly during one year. Were sampled 76 seeds m2 and 26 species. Tillandsia spp. (Bromeliaceae)
contributed with the majority (49%) of seed deposition. There was no significative correlation between
density of deposition of seeds and precipitation monthly. The seeds of woody plants (tree and bushes) were
preferentially autochoric.

Key words: semi arid, seed dispersal, seasonality.</abstract>
