Resumo: The aim of this study was to evaluate the induction of adventitious rooting in Eucalyptus benthamii mini-cuttings regarding to genotype, Zn and B concentrations, shoot collections and IBA application. Shoots for the mini-cuttings confection were collected from mini-stumps fertigated with nutrient solutions containing different concentrations of Zn and B (S1 – free of Zn and B, S2 – 0.5 mg L-1 Zn, S3 – 0.5 mg L-1 B, S4 – 0.5 mg L-1 Zn and B, S5 – 1.0 mg L-1 Zn and B, S6 – 2.0 mg L-1 Zn and B). The basal portion of the mini-cuttings was immersed for 10 s in a solution containing 2,000 mg L-1 IBA. A free IBA solution was used as control. The mini-cuttings survival in greenhouse, shade-house and in full sun area were evaluated. In full sun area, only the rooted mini-cuttings were evaluated, and of these, the total length of the root system was measured. The adventitious rooting of Eucalyptus benthamii mini-cuttings depended of the genotype, Zn and B concentrations, shoots collections and IBA application. In general, the adventitious rooting percentage was low, and the genotypes were considered difficult to propagation by mini-cuttings technique. The mini-cuttings collected of mini-stumps fertigated with nutrient solutions S5 (1.0 mg L-1 Zn and B) and S6 (2.0 mg L-1 Zn and B) associated with the presence of IBA in the concentration of 2,000 mg L-1 presented the greater adventitious rooting percentage.

As brotações foram oriundas de minicepas fertirrigadas com soluções nutritivas variando nas concentrações de Zn e B (S1 – isento de Zn e B, S2 – 0,5 mg L-1 de Zn, S3 – 0,5 mg L-1 de B, S4 – 0,5 mg L-1 de Zn e B, S5 – 1,0 mg L-1 de Zn e B, S6 – 2,0 mg L-1 de Zn e B). A região basal da miniestaca foi imersa durante 10 s em solução contendo 2.000 mg L-1 de AIB, sendo uma solução isenta de AIB utilizada como controle. Avaliaram-se a sobrevivência das miniestacas na saída da casa de vegetação, na saída da casa de sombra e em área de pleno sol. Em área de pleno sol foram avaliadas apenas as miniestacas enraizadas, e destas, o comprimento total do sistema radicial. O enraizamento adventício em miniestacas de Eucalyptus benthamii dependeu do material genético, da coleta de brotações, da aplicação de AIB e das concentrações de Zn e B. A porcentagem de enraizamento foi baixa, sendo que os materiais genéticos foram considerados de difícil propagação pela miniestaquia. Em termos gerais, as miniestacas obtidas de minicepas fertirrigadas com as soluções nutritivas S5 (1,0 mg L-1 de Zn e B) e S6 (2,0 mg L-1 de Zn e B) associadas a presença de AIB na concentração de 2.000 mg L-1 apresentaram os maiores índices de enraizamento.CERNE2016-04-062017-08-01T20:15:25Z2017-08-01T20:15:25Z2017-08-01info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfapplication/pdfhttp://www.cerne.ufla.br/site/index.php/CERNE/article/view/971BRONDANI, G.
