Resumo: | The aim of this work was to evaluate the effects of growth regulators TDZ [1-phenil-3-(1,2,3-thiadiazol-5-yl)urea], BAP (6-benzilaminopurine) e NAA (Naphthalene acetic acid) on the in vitro propagation by organogenesis from foliar explants of Eucalyptus grandis x E. urophylla. Depending on the clone used, there were singular responses to growth regulators treatment regarding callusing intensity, texture and color. The best results of the three genotypes used were observed with the TDZ (0.5 mg L-1) and NAA (0.1 mg L-1) treatment, where 100% of the foliar explants presented callus. The worst results were observed with the BAP (0.1 mg L-1) and NAA (0.1 mg L-1) treatment. Subsequently, considering the regeneration process, the best response was achieved with 1.0 mg L-1 BAP, in which 8% of the calli regenerated buds, with an average of 4.2 buds per explant. |

Houve resposta diferenciada dos clones quanto a intensidade, textura e coloração dos calos, em razão dos tratamentos com os reguladores de crescimento. Os melhores resultados de calejamento dos três genótipos foram observados nos tratamentos com a combinação dos reguladores de crescimento TDZ (0,5 mg L-1) e ANA (0,1 mg L-1), obtendo-se 100% de calejamento no explante foliar. Os piores resultados de calejamento foram observados nos tratamentos com a combinação dos reguladores de crescimento BAP (0,1 mg L-1) e ANA (0,1 mg L-1). Em relação à regeneração, a melhor resposta foi obtida com 1,0 mg L-1 BAP em que 8% dos calos formados a partir de explantes foliares regeneraram gemas, com número médio destas formadas por calo igual a 4,2.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraAlves, Elisa Cristina Soares de CarvalhoXavier, AloísioOtoni, Wagner Campos2010-10-06info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/9549Pesquisa Agropecuaria Brasileira; v.39, n.5, maio 2004; 421-430Pesquisa Agropecuária Brasileira; v.39, n.5, maio 2004; 421-4301678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/9549/5380info:eu-repo/semantics/openAccess2014-07-17T19:23:44Zoai:ojs.seer.sct.embrapa.br:article/9549Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2014-07-17T19:23:44Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false |
