Resumo

O banco de sementes no solo &#xE9; um dos mecanismos de regenera&#xE7;&#xE3;o natural que contribui para o surgimento
de esp&#xE9;cies em &#xE1;reas florestais ou degradadas, no entanto, a composi&#xE7;&#xE3;o de esp&#xE9;cies pode ser influenciada
pelo hist&#xF3;rico de uso da terra, pela matriz em que o fragmento est&#xE1; inserido, entre outros. O objetivo dessa
pesquisa foi avaliar a composi&#xE7;&#xE3;o flor&#xED;stica, abund&#xE2;ncia e ecologia morfofuncional de pl&#xE2;ntulas de esp&#xE9;cies
arb&#xF3;reas encontradas no banco de sementes no solo em fragmento de Floresta Tropical. Foram retiradas
amostras de solos e levadas para o viveiro florestal e cobertas por tela sombrite 70%. As pl&#xE2;ntulas emergidas
foram contadas, identificadas e classificadas quanto &#xE0; s&#xED;ndrome de dispers&#xE3;o, grupo sucessional e ecologia
morfofuncional dos cotil&#xE9;dones. Emergiram 3.441 pl&#xE2;ntulas, em 14 fam&#xED;lias e 28 morfoesp&#xE9;cies. Predominaram
Miconia prasina e Cecropiapachystachya com 22,20 e 17,78%, respectivamente; a s&#xED;ndrome zooc&#xF3;rica com
64%; houve predomin&#xE2;ncia de esp&#xE9;cies secund&#xE1;rias iniciais, seguida de pioneiras. 78% das pl&#xE2;ntulas s&#xE3;o do
tipo PEF (fanero-ep&#xED;geo-foli&#xE1;ceo). Embora o remanescente esteja inserido em uma matriz agr&#xED;cola possui
uma m&#xE9;dia riqueza de esp&#xE9;cies arb&#xF3;reas no banco de sementes, sendo a maioria das esp&#xE9;cies classificadas
como fanero-ep&#xED;geo-foli&#xE1;ceo, demonstrando a din&#xE2;mica e capacidade de autorregenera&#xE7;&#xE3;o da &#xE1;rea estudada.

Palavras-chave: autorregenera&#xE7;&#xE3;o, dispers&#xE3;o, mecanismo de regenera&#xE7;&#xE3;o.




Abstract

The seed bank in the soil is one of the mechanisms of natural regeneration that contributes to the emergence
of species in forest or degraded areas, however, the composition of species can be influenced by the history
of land use, by the matrix in which the fragment is inserted, among others. The objective of this research
was to evaluate the floristic composition, abundance and morphofunctional ecology of seedlings arboreal
species found in the soil seed bank in tropical forest fragment. Soil samples were taken and taken to the forest
nursery and covered by shading screens 70%. The emerged seedlings were counted, identified and classified
in terms of dispersion syndrome, successional group and morphological and functional ecology of cotyledons.
3,441 seedlings emerged in 14 families and 28 morphospecies. Miconia prasina and Cecropia pachystachya
predominated with 22.20 and 17.78%, respectively; zoochoric syndrome with 64%; there were predominance
of early secondary species, followed by pioneers. 78% of the seedlings are of the PEF type (phanero-epigealfoliaceous). 
Although the remnant is inserted in an agricultural matrix, it has an average tree species richness
in the seed bank, most species being classified as phanero-epigeal-foliaceous, demonstrating the dynamics
and self-regeneration capacity of the studied area.

Key words: self-regeneration, dispersion, mechanism of regeneration.</subfield>
