Resumo: | http://dx.doi.org/10.5902/1980509820592Seed size and dormancy level were studied in 20 trees from two populations of Schizolobium parahybatoevaluate how these characteristics occurbetween and within populations, and whether seed germinationwas affected by its morphometry. These two populations are located in the coastal (Paraty) or mountain(Miguel Pereira) regions in the state of Rio de Janeiro, Brazil. The seed morphometrictraits (length,width, thickness and weight) were measured. Germination with or without seedcoatdormancy treatment(mechanical scarification) wasassessedbya randomized emergence test in nursey. All morphometric traitsdiffered significantly among individuals and between populations. The trees from the mountain regionshowed a larger seed size and a lower dormancy level than that of trees from the coastal region. Seed sizehad no effect on seed germination or seedling development. Climate influence on the determination of germination behavior is discussed based on the results. |

As populações são procedentes da região litorânea (Paraty) e montanhosa (Miguel Pereira) no Estado do Rio de Janeiro. As características morfométricas (comprimento, largura, espessura e massa) foram medidas e a germinação com e sem tratamento de quebra de dormência (escarificação mecânica) foi avaliada em um teste de emergência com delineamento inteiramente casualizado. Todas as variáveis morfométricas diferiram significativamente entre indivíduos e entre populações. As matrizes da região montanhosa apresentaram maior tamanho da semente e um menor nível de dormência do que aquelas localizadas na região litorânea. O tamanho da semente não influenciou a germinação das sementes e o desenvolvimento das plântulas. A influência do clima na seleção do comportamento germinativo da espécie foi discutido com base nos resultados obtidos.Universidade Federal de Santa Maria2015-12-30info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.ufsm.br/cienciaflorestal/article/view/2059210.5902/1980509820592Ciência Florestal; Vol. 25 No. 4 (2015); 897-907Ciência Florestal; v. 25 n. 4 (2015); 897-9071980-50980103-9954reponame:Ciência Florestal (Online)instname:Universidade Federal de Santa Maria (UFSM)instacron:UFSMporhttps://periodicos.ufsm.br/cienciaflorestal/article/view/20592/pdfFreire, Juliana MüllerPiña-Rodrigues, Fátima Conceição M.Santos, André Luís Fonseca dosPereira, Maurício Ballesteiroinfo:eu-repo/semantics/openAccess2017-04-10T12:51:43Zoai:ojs.pkp.sfu.ca:article/20592Revistahttp://www.ufsm.br/cienciaflorestal/ONGhttps://old.scielo.br/oai/scielo-oai.php||cienciaflorestal@ufsm.br|| cienciaflorestal@gmail.com|| cf@smail.ufsm.br1980-50980103-9954opendoar:2017-04-10T12:51:43Ciência Florestal (Online) - Universidade Federal de Santa Maria (UFSM)false |
