Resumo: | The objective of this research was to evaluate the seed viability of mutamba (G. ulmifolia) at different times of burying and depth in the soil in an induced soil seed bank. A randomized block design was used in a 3 x 3 factorial scheme with four plots. The treatments used were three soils depths (0, 2 and 4cm) and three times (3, 4 and 5 months after burying). Each plot had 500 seeds in a bag (10x10cm) buried in nursery soil. The evaluations were seed viability with intact seed, using germination tests, obtaining the number of root emergences, normal seedlings and hard seeds. Further, the number of losses in the soil seed bank were evaluated. The results obtained showed that the mutamba seeds (G. ulmifolia) could stay viable in the soil seed bank after 5 months (25% of total seed buriying showing 72% viability). Seeds on the soil surface and 2cm deep had better average of root emergence and normal seedling percentage than that 4cm deep. The percentage of losses in soil seed bank is 61%, regardless of depth or time. |

O delineamento utilizado foi blocos casualizados, em esquema fatorial 3x3, com quatro repetições. Os tratamentos empregados foram três profundidades de semeadura (0, 2 e 4cm) e três épocas de avaliação (3, 4 e 5 meses). Cada repetição consiste em 500 sementes, colocadas em sacos tipo filó (10x10cm) e enterradas em sementeira. Em cada época, foi avaliada a viabilidade das sementes por meio de teste de germinação, obtendo-se o percentual de emissão de raiz; plântulas normais e sementes firmes/duras. Foi avaliado, ainda, o percentual de saída do banco (contado através das perdas). As sementes de mutamba (G. ulmifolia) mantiveram-se viáveis no solo (25% do total das sementes enterradas apresentando 72% de viabilidade), mesmo após cinco meses enterradas. As sementes colocadas na superfície do solo e enterradas a 2cm de profundidade apresentam maior taxa de emergência de plântulas no campo do que as sementes enterradas a 4cm. O percentual médio de perdas é de, aproximadamente, 61%, independente da profundidade de semeadura e do tempo de permanência no solo.São Cristóvão, SEporAssociação Brasileira de Tecnologia de SementesRevista Brasileira de SementesViabilidadeBanco de sementes introduzidoEspécie florestalSementesMutambaGuazuma ulmifoliaSeed viabilitySoil seed bankForest speciesLongevidade de sementes de mutamba (Guazuma ulmifolia Lam. – Sterculiaceae) no solo em condições naturaisSeed ongevity of mutamba (Guazuma ulmifolia Lam. – Sterculiaceae) in the soil under natural conditionsinfo:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/articlereponame:Repositório Institucional da UFSinstname:Universidade Federal de Sergipe (UFS)instacron:UFSinfo:eu-repo/semantics/openAccessTEXTLongevidadeSementesMutamba.pdf.txtLongevidadeSementesMutamba.pdf.txtExtracted texttext/plain35377https://ri.ufs.br/jspui/bitstream/riufs/11929/3/LongevidadeSementesMutamba.pdf.txtd22b180f88c7e9ddb03d5160ce45e6e9MD53THUMBNAILLongevidadeSementesMutamba.pdf.jpgLongevidadeSementesMutamba.pdf.jpgGenerated Thumbnailimage/jpeg1501https://ri.ufs.br/jspui/bitstream/riufs/11929/4/LongevidadeSementesMutamba.pdf.jpg68ed79fbad0ce676f65af900f438c321MD54LICENSElicense.txtlicense.txttext/plain; charset=utf-81475https://ri.ufs.br/jspui/bitstream/riufs/11929/1/license.txt098cbbf65c2c15e1fb2e49c5d306a44cMD51ORIGINALLongevidadeSementesMutamba.pdfLongevidadeSementesMutamba.pdfapplication/pdf180651https://ri.ufs.br/jspui/bitstream/riufs/11929/2/LongevidadeSementesMutamba.pdfb98ad7ee93f5a834a6922628c2d0e78fMD52riufs/119292019-09-17 09:06:45.223oai:ufs.br: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Repositório InstitucionalPUBhttps://ri.ufs.br/oai/requestrepositorio@academico.ufs.bropendoar:2019-09-17T12:06:45Repositório Institucional da UFS - Universidade Federal de Sergipe (UFS)false |
