Resumo: | The composition and quality of the seed bank are some of the factors responsible for the structure and floristic composition of forest environments. The aim of this study was to evaluate the seed bank of a semideciduous forest patch, taking into account the influence of the landscape’s topographical features. Two adjacent landforms, of convex and concave shapes, were selected. They were divided into mini sites (MS) I, II, and III in the convex landform and IV, V and VI in the concave one. Ten sample points on each MS were randomly distributed with a surface area of 0.0625 m² and 3 cm deep. A total of 4,862 germinated seeds.m-1 was registered in 90 days, with the convex landform presenting the highest frequency of germinated seeds.m-1. A total of 35 families and 88 species were identified in both landforms, of which 37% were of herbaceous habit, 24% arboreal, 18% shrubs, 12% lianas and 2% epiphytic. Regarding the landform’s shape, 44% of the species were found in both convex and concave ones, 31% were found exclusively on the convex landform and 25% exclusively on the concave one. Regarding floristic and phytosociological parameters, the convex landform accounted for a higher number of seeds, families, and species richness, while the concave landform accounted for higher diversity. Topography was a determinant factor for the floristic and phytosociological composition of the seed bank. The highest species richness was recorded in the convex landform and highest diversity in the concave landform, with Asteraceae, Melastomataceae and Urticaceae families presenting the highest importance indexes of value. |

O objetivo deste estudo foi avaliar o banco de sementes de um fragmento de Floresta Estacional Semidecidual, com influência das características topográficas da paisagem. Foram selecionadas duas pedoformas adjacentes com relevo do tipo convexa e côncava, sendo essas divididas em minissítios (MS) I, II, e III na pedoforma convexa, e IV, V, VI na pedoforma côncava. Foram amostrados 10 pontos de cada MS, distribuídos assistematicamente, com uma área superficial de 0,0625 m² e profundidade de 3 cm. Foi registrado um total de 4.862 sementes.m-1 germinadas no período de 90 dias, sendo na pedoforma convexa observado o maior número de sementes.m-1 germinadas. Em ambas as pedoformas, foram identificadas 35 famílias e 88 espécies; dentre as espécies, 37% têm hábito herbáceo; 24%, arbóreo; 18%, arbustivo; 12%, trepador; e 2%, epifítico. Quanto ao tipo de pedoforma, foram registradas 44% das espécies encontradas em ambas, 31% foram exclusivas da convexa e 25%, da côncava. Para aos parâmetros florísticos e fitossociológicos, a pedoforma convexa apresentou maior número de sementes, famílias, espécies e riqueza, enquanto a côncava teve maiores índices de diversidade. As condições topográficas foram determinantes na composição florística e fitossociológica do banco de sementes, sendo os maiores valores de riqueza verificados na pedoforma convexa e de diversidade, na côncava, com maior índice de valor de importância para as famílias Asteraceae, Melastomataceae e Urticaceae.Universidade Federal de Santa Maria2017-12-11info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.ufsm.br/cienciaflorestal/article/view/3031010.5902/1980509830310Ciência Florestal; Vol. 27 No. 4 (2017); 1217-1228Ciência Florestal; v. 27 n. 4 (2017); 1217-12281980-50980103-9954reponame:Ciência Florestal (Online)instname:Universidade Federal de Santa Maria (UFSM)instacron:UFSMporhttps://periodicos.ufsm.br/cienciaflorestal/article/view/30310/16793Copyright (c) 2017 Ciência Florestalinfo:eu-repo/semantics/openAccessSantos, Gilsonley Lopes dosPereira, Marcos GervasioConto, Tiago deCarvalho, Daniel Costa deAmorim, Thiago Azevedo deMendonça, Victoria Maria MonteiroMorais, Luiz Fernando Duarte de2017-12-12T00:35:45Zoai:ojs.pkp.sfu.ca:article/30310Revistahttp://www.ufsm.br/cienciaflorestal/ONGhttps://old.scielo.br/oai/scielo-oai.php||cienciaflorestal@ufsm.br|| cienciaflorestal@gmail.com|| cf@smail.ufsm.br1980-50980103-9954opendoar:2017-12-12T00:35:45Ciência Florestal (Online) - Universidade Federal de Santa Maria (UFSM)false |
