Resumo: The seed bank of a prairie which has not been ploughed for at least 40 years was analysed and compared with standing vegetation. There were 28 species in the seed bank: 18 monocotyledoneae and 10 dicotyledoneae, plus five unknown species. In the standing vegetation there were 39 species: 19 monocotyledoneae and 20 dicotyledoneae. Seed bank and standing vegetation share 18 out of 49 known species and their similarity is 54% (Sorensen index). The seeds have an aggregate distribution, therefore the bank is very heterogeneous.

Comparou-se com a vegetação do lugar. Acharam-se 28 espécies no banco de sementes: 18 monocotiledôneas e 10 dicotiledôneas, mais cinco espécies desconhecidas. Na vegetação foram arroladas 39 espécies: 19 monocotiledôneas e 20 dicotiledôneas. O banco de sementes comparte 18 espécies, das 49 conhecidas, com a vegetação, e a similitude entre elas é de 54% (índice de Sorensen). As sementes têm distribuição agregada, constituindo um banco muito heterogêneo.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraBoccanelli, Silvia I.Lewis, J.
