Abstract

In this research it was evaluated the potential of the soil seed bank in a remaining of Subtropical Ombrophilous Alluvial Forest (Araucaria Forest), by quali-quantitative analysis of seed germination. Additionally it was tested the occurrence of seasonal variation of the soil seed bank. The forest remaining located in Araucaria county, Parana State, Brazil, and it is influenced by Barigui river, affluent of Iguaçu river. It was used the completely randomized experimental design with ten replications. The soil seed bank was collected in three seasons at depth (of 10 cm plus litter), using a 0.40 m x 0.40 m sample square. The collected samples were placed in wood boxes in greenhouse, during 8 months. It was observed a season average of 5,732 individuals m-2, distributed into 276 species (120 genus, 54 families). A total of 34,780 seeds germinate. The number of seeds did not presented statistical difference among seasons. The floristic composition of the soil seed bank was influenced by anthropized surrounding areas.
