Resumo: | The control of soil seed bank (SSB) dynamics is crucial to the ecologies of plant populations of many species, but has been little studied in tropical environments. The objectives of this work were to characterize the SSB of Acrocomia aculeata, an important neotropical oleaginous palm, and to define the influence of edaphic and climatic factors on its dynamics. Exposed and buried diaspores were collected in five areas of the Cerrado biome in central Brazil. Evaluations of the diaspores, young plants, and in vitro embryo cultures defined 26 indicators of SSB dynamics that were correlated with 19 physical-chemical attributes of the soil. Seedlings emergence was studied under greenhouse conditions during five years and the thermal control of germination was evaluated experimentally. A. aculeata forms persistent SSBs, with P being the main edaphic factor associated with seed input. High levels of Al and clay (associated with insect predation), organic matter (fungal contamination), and sand (bacterial contamination) contributed to negative outputs (embryo death). The maintenance of intact SSB embryos, however, is independent of edaphic factors. Wide thermal amplitudes in the winter associated with high temperatures in the spring promote overcoming dormancy and favor positive SSB outputs as well as the synchronization of seedling emergence at the beginning of rainy season. The high productivity of A. aculeata and its ability to maintain viable but dormant embryos in the soil contribute to controlling SSB dynamics, reproductive success, and its wide distribution. |

Os objetivos deste trabalho foram caracterizar o SSB de Acrocomia aculeata, importante palmeira oleaginosa neotropical, e definir a influência de fatores edáficos e climáticos em sua dinâmica. Diásporos expostos e enterrados foram coletados em cinco áreas do bioma Cerrado no Brasil central. As avaliações dos diásporos, plantas jovens e culturas de embriões in vitro definiram 26 indicadores da dinâmica do SSB que foram correlacionados com 19 atributos físico-químicos do solo. A emergência de plântulas foi estudada em casa de vegetação durante cinco anos e o controle térmico da germinação foi avaliado experimentalmente. A. aculeata forma SSBs persistentes, sendo o P o principal fator edáfico associado à entrada de sementes. Altos níveis de Al e argila (associados à predação de insetos), matéria orgânica (contaminação fúngica) e areia (contaminação bacteriana) contribuíram para resultados negativos (morte de embriões). A manutenção de embriões SSB intactos, no entanto, é independente de fatores edáficos. Amplas amplitudes térmicas no inverno associadas a altas temperaturas na primavera promovem a superação da dormência e favorecem saídas positivas de SSB, bem como a sincronização da emergência das plântulas no início da estação chuvosa. A alta produtividade de A. aculeata e sua capacidade de manter no solo embriões viáveis, porém dormentes, contribuem para o controle da dinâmica do SSB, sucesso reprodutivo e sua ampla distribuição.CNPq - Conselho Nacional de Desenvolvimento Científico e TecnológicoFAPEMIG - Fundação de Amparo à Pesquisa do Estado de Minas GeraisengUniversidade Federal de Minas GeraisUFMGBrasilICA - INSTITUTO DE CIÊNCIAS AGRÁRIASIndustrial Crops and ProductsSementes - DormênciaBancos de sementesSolos - ComposiçãoGerminaçãoÓleo de palmeiraEdaphic and climatic control of macaúba palm seed bank dynamicsControle edáfico e climático da dinâmica do banco de sementes de macaúbainfo:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/articlehttps://www.sciencedirect.com/science/article/pii/S092666901930812X?msclkid=4c771f7eab7511ecad46377e76f5c029Joyce Nascimento e SouzaCleidiana de Oliveira AgostinhoLeonardo Monteiro RibeiroAlcinei Místico AzevedoPaulo Sérgio Nascimento Lopesinfo:eu-repo/semantics/openAccessreponame:Repositório Institucional da UFMGinstname:Universidade Federal de Minas Gerais (UFMG)instacron:UFMGLICENSELicense.txtLicense.txttext/plain; charset=utf-82042https://repositorio.ufmg.br/bitstream/1843/40413/1/License.txtfa505098d172de0bc8864fc1287ffe22MD51ORIGINALEdaphic and climatic control of macaúba palm seed bank dynamics.pdfEdaphic and climatic control of macaúba palm seed bank dynamics.pdfapplication/pdf4391889https://repositorio.ufmg.br/bitstream/1843/40413/2/Edaphic%20and%20climatic%20control%20of%20maca%c3%baba%20palm%20seed%20bank%20dynamics.pdf3b14aa094ac8838e25f2a3b8f4513c6bMD521843/404132022-03-24 11:17:09.78oai:repositorio.ufmg.br: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Repositório de PublicaçõesPUBhttps://repositorio.ufmg.br/oaiopendoar:2022-03-24T14:17:09Repositório Institucional da UFMG - Universidade Federal de Minas Gerais (UFMG)false |

The control of soil seed bank (SSB) dynamics is crucial to the ecologies of plant populations of many species, but has been little studied in tropical environments. The objectives of this work were to characterize the SSB of Acrocomia aculeata, an important neotropical oleaginous palm, and to define the influence of edaphic and climatic factors on its dynamics. Exposed and buried diaspores were collected in five areas of the Cerrado biome in central Brazil. Evaluations of the diaspores, young plants, and in vitro embryo cultures defined 26 indicators of SSB dynamics that were correlated with 19 physical-chemical attributes of the soil. Seedlings emergence was studied under greenhouse conditions during five years and the thermal control of germination was evaluated experimentally. A. aculeata forms persistent SSBs, with P being the main edaphic factor associated with seed input. High levels of Al and clay (associated with insect predation), organic matter (fungal contamination), and sand (bacterial contamination) contributed to negative outputs (embryo death). The maintenance of intact SSB embryos, however, is independent of edaphic factors.
