Resumo: The objective of this research was to compare the efficiency of methods to suppress tegument impermeability on Leucaena diversifolia seeds. Seeds were collected in Botucatu, São Paulo State, Brazil, in May 2003, and allowed to dry in the shadow at room temperature. Samples taken from pure seed fraction were submitted to the following treatments: immersion in boiling water for one and two minutes; immersion in concentrated sulfuric acid (H2SO4) for one, three, and five minutes; immersion in H2SO4 diluted to 60% for five and ten minutes; and control (intact seeds). Germination tests indicated the concentrated H2SO4 for five inutes as the most efficient treatment. KEY-WORDS: Dormancy; Leucaena; germination.

O objetivo da pesquisa foi comparar a eficiência de métodos para superação da impermeabilidade do tegumento em sementes de Leucaena diversifolia L. Sementes colhidas em Botucatu, Estado de São Paulo, em maio de 2003, foram secadas à sombra em ambiente não controlado e, da fração de sementes puras, foram retiradas amostras, submetidas aos seguintes tratamentos: imersão em água em ebulição por um e dois minutos; imersão em ácido sulfúrico (H2SO4) concentrado por um, três e cinco minutos; imersão em H2SO4 diluído a 60% por cinco e dez minutos; e testemunha (sementes intactas). As sementes foram então submetidas ao teste de germinação, concluindo-se que o tratamento mais eficiente foi H2SO4 concentrado por cinco minutos.Escola de Agronomia - Universidade Federal de Goiás2007-10-15info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionAvaliado por paresPesquisa experimentalapplication/pdfhttps://revistas.ufg.br/pat/article/view/1853Pesquisa Agropecuária Tropical [Agricultural Research in the Tropics]; v. 37, n. 3, Jul./Sep. 2007; 142-146Pesquisa Agropecuária Tropical (Agricultural Research in the Tropics); v. 37, n. 3, jul./set. 2007; 142-146Pesquisa Agropecuária Tropical; v. 37, n. 3, jul./set. 2007; 142-1461983-4063reponame:Pesquisa Agropecuária Tropical (Online)instname:Universidade Federal de Goiás (UFG)instacron:UFGporhttps://revistas.ufg.br/pat/article/view/1853/1759Souza, Eli Regina Barboza deZago, RuthGarcia, JoséFarias, João GasparCarvalho, Edite Mesquita dos SantosRodrigues, Michelle Barrosoinfo:eu-repo/semantics/openAccess2020-02-27T00:01:36Zoai:ojs.revistas.ufg.br:article/1853Revistahttps://revistas.ufg.br/patPUBhttps://revistas.ufg.br/pat/oaiaseleguini.pat@gmail.com||mgoes@agro.ufg.br1983-40631517-6398opendoar:2024-05-21T19:54:53.142214Pesquisa Agropecuária Tropical (Online) - Universidade Federal de Goiás (UFG)true
