Resumo: | The objective of this study was to evaluate the mini cutting technique as a method of vegetative propagation of Eucalyptus dunnii, as related to the production and survival of the mini stumps in the successive collections, and to the survival, rooting, height growth and collar diameter of the mini cuttings. After four successive collections the mini stumps was observed an average survival of 100% and average production between 1.7 to 2.6 mini cuttings per mini stump. The survival of the mini cuttings when they left the greenhouse was 100% and the average rooting at the end of acclimatization period in shade house with 50% solar light was 93%, and the survival to 90 days of age from 90%, without positive influence of the different treatments of AIB (0, 1500, 3000 e 6000 mg L-1.) At specific conditions on wich the experiment was realized with mini cuttings of Eucalyptus dunnii, from material of seminal origin, is technically viable, and this technique can be an alternative for production seedlings of this species in wide scale and mainly in situations where seed is a limiting factor. |

Após quatro coletas sucessivas, as minicepas apresentaram 100% de sobrevivência e produção média entre 1,7 e 2,6 miniestacas por minicepa. A sobrevivência das miniestacas na saída da casa de vegetação foi de 100% e, em média, o enraizamento na saída da casa de sombra com 50% de filtração solar foi de 93% e a sobrevivência aos 90 dias de idade de 90%, sem influência positiva dos diferentes tratamentos de AIB (0, 1500, 3000 e 6000 mg L-1). Assim, nas condições em que foi realizado o experimento, a miniestaquia de Eucalyptus dunnii, a partir de material de origem seminal, é tecnicamente viável, tornando-se uma possível alternativa para a produção de mudas desta espécie em larga escala e, principalmente, nas situações onde a semente é um fator limitante.Embrapa Florestas2003-06-30info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://pfb.cnpf.embrapa.br/pfb/index.php/pfb/article/view/1615Pesquisa Florestal Brasileira; n. 46 (2003): jan./jun.; 21-30Pesquisa Florestal Brasileira; No. 46 (2003): jan./jun.; 21-301983-26051809-3647reponame:Pesquisa Florestal Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://pfb.cnpf.embrapa.br/pfb/index.php/pfb/article/view/1615/623Souza Junior, LeviWendling, Ivarinfo:eu-repo/semantics/openAccess2018-03-22T17:49:20Zoai:pfb.cnpf.embrapa.br/pfb:article/1615Revistahttps://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:2018-03-22T17:49:20Pesquisa Florestal Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false |
