Resumo: | With the objective of evaluating soil seed bank and understanding aspects of the sucessional dynamics of a Seasonal Deciduous Forest, 60 samples of 1 m2 were collected at the end of each season, in three sucessional phases (understory, secondary forest and mature forest). In each sample point it was collected the litter and the first 3 cm of soil. In laboratory at UFSM the material was placed to germinate, separately, in stonemasons of wood of 1 m2, that contained 5 cm of horizon B soil as substratum. The stonemasons were covered with sombrite of 50% for understory, 70% for the secondary forest and 80% for the mature forest. There were made qualitative and quantitative evaluations, by species and sample unit, 20 days after placing in nursery and afterward every 30 days. The frequency and relative density, the Index of Value of Importance for the seed bank and the Index of Diversity of Shannon were calculated. There were 216 individuals, most of them in the mature forest, which also presented the largest floristic richness. In the three subseres, there was predominance of secondary initial species. The spring season presented the largest abundance of species; however, in summer happened the largest density of individuals per area. |

Em cada ponto amostral, foi coletado o folhedo e os primeiros 3 cm de solo. No Centro Tecnológico de Silvicultura da UFSM o material foi posto para germinar, separadamente, em canteiros de madeira de 1 m2, que continham 5 cm de solo de horizonte B como substrato. Os canteiros foram cobertos com sombrite de 50% de sombreamento para o Capoeirão, 70% para a Floresta Secundária e 80% para a Floresta Madura. Foram feitas avaliações qualitativas e quantitativas, por espécie e unidade amostral, 20 dias após a instalação no viveiro e posteriormente a cada 30 dias. Foram calculadas a freqüência e densidade relativas e o Índice de Diversidade de Shannon. Encontraram-se 216 indivíduos, sendo a maioria deles na Floresta Madura, a qual também apresentou a maior riqueza florística. Nas três subseres, houve predominância de espécies secundárias iniciais. A estação de primavera apresentou a maior abundância de espécies, porém, no verão ocorreu a maior densidade de indivíduos por área.Universidade Federal de Santa Maria2005-12-30info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.ufsm.br/cienciaflorestal/article/view/187310.5902/198050981873Ciência Florestal; Vol. 15 No. 4 (2005); 359-370Ciência Florestal; v. 15 n. 4 (2005); 359-3701980-50980103-9954reponame:Ciência Florestal (Online)instname:Universidade Federal de Santa Maria (UFSM)instacron:UFSMporhttps://periodicos.ufsm.br/cienciaflorestal/article/view/1873/1120Longhi, Solon JonasBrun, Eleandro JoséOliveira, Diógenes MauriceFialho, Luis Eduardo BrittoWojciechowski, Julio CésarVaccaro, Sandroinfo:eu-repo/semantics/openAccess2017-05-15T18:10:21Zoai:ojs.pkp.sfu.ca:article/1873Revistahttp://www.ufsm.br/cienciaflorestal/ONGhttps://old.scielo.br/oai/scielo-oai.php||cienciaflorestal@ufsm.br|| cienciaflorestal@gmail.com|| cf@smail.ufsm.br1980-50980103-9954opendoar:2017-05-15T18:10:21Ciência Florestal (Online) - Universidade Federal de Santa Maria (UFSM)false |
