Resumo: | Soilseed bankastogrant recovery of the riparian forest. The present work objective knows the density and composition of soil seed bank in ciliary areas altered in spill of two springs. The studied springs belong to Capivari river catchment, Itumirim, MG (21º16'S and 44º52 ' W). The samples of soils were collected in the end of the rainy station (May of 2003). Were 18 soil samples were collected for the two environments to the depth of 5 cm. was calculated the density of seeds and the curve of germination of the soil seed bank, for method of seedling emergency. It was also made the determination of the floristic composition based mainly on the morphology of the seedling. After a period of 210 days of evaluation obtained a density of 2332 seed/m2 was observed in the environment I and 1896 seed/m2, for the environment. However, it was verified that the bank of seeds of the two appraised East was just composed of ruderal species. Such results evidence the need of human intervention in the process of restoration of the ciliary vegetation in spill of this spring, through the artificial regeneration of the arboreal species. |

A nascente estudada pertence à bacia hidrográfica do rio Capivari, no município de Itumirim, MG (21º16’ S e 44º52’ W). Nos dois ambientes estudados, foram coletadas 18 amostras de solo a 5,0 cm profundidade, no final da estação chuvosa (maio de 2003). Calculou-se a densidade de sementes e a curva de germinação do banco pelo método de emergência de plântulas. Também foi feita a determinação da composição florística, com base principalmente na morfologia das plântulas. Após um período de 210 dias de avaliação, obteve-se uma densidade de 2.332 sementes/m2 no Ambiente I e 1.896 sementes/m2 no Ambiente II. No entanto constatou-se que o banco de sementes dos dois ambientes avaliados era composto apenas por espécies ruderais. Tais resultados evidenciam a necessidade de intervenção humana no processo de recomposição da vegetação ciliar no entorno dessa nascente, por meio da regeneração artificial de espécies arbóreas.Universidade Federal do Paraná (UFPR)2020-10-11T22:54:05Z2020-10-11T22:54:05Z2010-12info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/articleapplication/pdfPEREIRA, I.
