Resumo: The flamboyant tree (Delonix regia) is known for its exuberant flowering. It shows great variation in seeds viability, depending on the cutaneous water proofing, requiring processes to break dormancy. The objective of this study was to evaluate methods of breaking the physical barrier of seeds. In the greenhouse, seeds were subjected to different treatments to overcome the cutaneous restriction: mechanical scarification on the ventral part; thermal shock with soaking seeds in water at 80 °C for 10 min; soaking the seeds in sulfuric acid, and control, without intervention. It was observed that the mechanical scarification provided the best results for dormancy breaking of the seeds.

Apresenta sementes com grande variação na viabilidade, em função da impermeabilidade tegumentar, necessitando de processos para superação da dormência. Neste sentido, objetivou-se com este trabalho, avaliar métodos para quebra da dormência das sementes em casa de vegetação. As sementes foram submetidas a diferentes tratamentos para superar a restrição tegumentar: escarificação mecânica na parte ventral; choque térmico com imersão das sementes em água a 80 ºC por 10 min e imersão das sementes em ácido sulfúrico, tendo como controle a semeadura sem intervenção. Observou-se que a escarificação mecânica proporcionou os melhores resultados para quebra de dormência das sementes.Embrapa Florestas2013-12-31info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://pfb.cnpf.embrapa.br/pfb/index.php/pfb/article/view/56810.4336/2013.pfb.33.76.568Pesquisa Florestal Brasileira; v. 33 n. 76 (2013): out./dez.; 463-467Pesquisa Florestal Brasileira; Vol. 33 No. 76 (2013): out./dez.; 463-4671983-26051809-3647reponame:Pesquisa Florestal Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://pfb.cnpf.embrapa.br/pfb/index.php/pfb/article/view/568/346Zwirtes, Anderson LuizBaronio, Cléber AntonioCantarelli, Edison BisogninRigon, João Paulo GonsiorkiewiczCapuani, Silviainfo:eu-repo/semantics/openAccess2017-04-28T12:50:05Zoai:pfb.cnpf.embrapa.br/pfb:article/568Revistahttps://pfb.cnpf.embrapa.br/pfb/index.php/pfb/PUBhttps://pfb.cnpf.embrapa.br/pfb/index.php/pfb/oaipfb@embrapa.br || revista.pfb@gmail.com || patricia.mattos@embrapa.br1983-26051809-3647opendoar:2017-04-28T12:50:05Pesquisa Florestal Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false
