Resumo: Vegetative propagation of imbuya (Ocotea porosa) and the germination process of its seeds is slow, justifying tetrazolium test, that is faster for verifying viability of seeds. Seeds of Colombo (PR)  native trees were collected and treated with 0.1 %, 0.3 % and 0.5 % tetrazolium solutions for one and two hours, presenting percentual  variation associated with the different treatments. No statistical significant differences were observed among different treatments. Viable seeds varied among 50 % and 85 %. Tetrazolium 0.5 % for one hour was suggested as the minimum for verifying viability of imbuya seeds.

Não constatou-se diferenças estatisticamente significativas entre tratamentos. O percentual desementes viáveis variou de 50 % a 85 %. Diante dos resultados obtidos, sugere-se a concentração de 0,5 % poruma hora como o tratamento mínimo para verificação da viabilidade das sementes de imbuia.Embrapa Florestas2010-03-15info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://pfb.cnpf.embrapa.br/pfb/index.php/pfb/article/view/55Pesquisa Florestal Brasileira; n. 57 (2008): jul./dez.; 69Pesquisa Florestal Brasileira; No. 57 (2008): jul./dez.; 691983-26051809-3647reponame:Pesquisa Florestal Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://pfb.cnpf.embrapa.br/pfb/index.php/pfb/article/view/55/55Kalil Filho, Antonio NascimLopes, Alexandre JacobusRêgo, Gizelda MaiaTomachitz, Adilsoninfo:eu-repo/semantics/openAccess2017-04-28T14:07:37Zoai:pfb.cnpf.embrapa.br/pfb:article/55Revistahttps://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:2017-04-28T14:07:37Pesquisa Florestal Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false
