Resumo: | Soil seed banks bring information about the current flora and allow future scenarios about plant communities. The objective of this work was to determine the percentage of ex situ germination of a seed bank under different levels of light. Sampling took place in primary a harvested primary forest under fallow in the municipality of Moju, Pará state, Brazil. Ten samples composed of four simple samples were collected in 10 plots of the topsoil (5 cm). The samples were maintained in a greenhouse and randomly distributed in Styrofoam trays under three light conditions: Shade (greenhouse + 70% shade net); Medium Shade (greenhouse + 30% shade net), and Full Sun, with five repetitions each. After 120 days, the seed bank presented 414 seedlings of 61 species, 48 genera, and 34 families. From this total, 27.78% of the individuals germinated in the three environments analyzed. The environment with the highest germination of individuals was Medium Shade (F = 140.25; p = 0.0001; CV = 3.60%), which also included 48.15% of the germinated species. The seed bank showed high floristic diversity with a predominance of tree, pioneer, and zoochoric species. In this way, environmental conditions determine the germination of the seed bank, with emphasis on the Medium Shade environment and the Fabaceae, Rubiaceae and Urticaceae families. |

El objetivo de este trabajo fue determinar el porcentaje de germinación ex situ de un banco de semillas a diferentes niveles de luz. El muestreo se realizó en bosque primario explorado en barbecho en el municipio de Moju, estado de Pará, Brasil. Se recolectaron diez muestras compuestas por cuatro muestras simples en 10 parcelas de la capa superior del suelo (5 cm). Las muestras se mantuvieron en un invernadero y se distribuyeron aleatoriamente en bandejas de poliestireno bajo tres condiciones de luz: Sombra (invernadero + 70% red de sombra); Sombra Media (invernadero + 30% red de sombra) y Pleno Sol, con cinco repeticiones cada una. Después de 120 días, el banco de semillas presentó 414 plántulas de 61 especies, 48 géneros y 34 familias. De este total, 27,78% de los individuos germinaron en los tres ambientes analizados. El ambiente con mayor germinación de individuos fue Sombra Media (F = 140,25; p = 0,0001; CV = 3,60%), que también incluyó 48,15% de las especies germinadas. El banco de semillas mostró una alta diversidad florística con predominio de especies arbóreas, pioneras y zoocóricas. De esta manera, las condiciones ambientales determinan la germinación del banco de semillas, con énfasis en el ambiente de Sombra Media y las familias Fabaceae, Rubiaceae y Urticaceae.Bancos de sementes do solo trazem informações sobre a flora atual e permitem cenários futuros sobre as comunidades vegetais. O objetivo deste trabalho foi determinar o percentual de germinação ex situ de um banco de sementes em diferentes níveis de luminosidade. A amostragem ocorreu em floresta primária explorada sob pousio no município de Moju, estado do Pará, Brasil. Foram coletadas 10 amostras compostas por quatro amostras simples em 10 parcelas da camada superficial do solo (5 cm). As amostras foram mantidas em casa de vegetação e distribuídas aleatoriamente em bandejas de isopor sob três condições de luminosidade: Sombra (casa de vegetação + 70% de sombrite); Sombra Média (casa de vegetação + 30% de sobrite) e Pleno Sol, com cinco repetições cada. Após 120 dias, o banco de sementes apresentou 414 plântulas de 61 espécies, 48 gêneros e 34 famílias. Deste total, 27,78% dos indivíduos germinaram nos três ambientes analisados. O ambiente com maior germinação de indivíduos foi Sombra Média (F = 140,25; p = 0,0001; CV = 3,60%), o qual também incluiu 48,15% das espécies germinadas. O banco de sementes apresentou alta diversidade florística com predominância de espécies arbóreas, pioneiras e zoocóricas. Desta forma, condições ambientais determinam a germinação do banco de sementes, com destaque ao ambiente Sombra Média e às famílias Fabaceae, Rubiaceae e Urticaceae.Research, Society and Development2021-01-09info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://rsdjournal.org/index.php/rsd/article/view/1152310.33448/rsd-v10i1.11523Research, Society and Development; Vol. 10 No. 1; e22710111523Research, Society and Development; Vol. 10 Núm. 1; e22710111523Research, Society and Development; v. 10 n. 1; e227101115232525-3409reponame:Research, Society and Developmentinstname:Universidade Federal de Itajubá (UNIFEI)instacron:UNIFEIporhttps://rsdjournal.org/index.php/rsd/article/view/11523/10442Copyright (c) 2021 Iracema Maria Cordeiro; Osmar Alves Lameira; Raphael Prado Neves; Gustavo Schwartzhttps://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccessCordeiro, Iracema Maria Lameira, Osmar AlvesNeves, Raphael Prado Schwartz, Gustavo2021-02-20T21:19:23Zoai:ojs.pkp.sfu.ca:article/11523Revistahttps://rsdjournal.org/index.php/rsd/indexPUBhttps://rsdjournal.org/index.php/rsd/oairsd.articles@gmail.com2525-34092525-3409opendoar:2024-01-17T09:33:19.417436Research, Society and Development - Universidade Federal de Itajubá (UNIFEI)false |
