QUALIDADE DA SECAGEM CONVENCIONAL CONJUNTA DA MADEIRA DE CLONES DE TRÊS ESPÉCIES DE Eucalyptus sp.

open access: yesCiência Florestal, 2015
The Brazilian industry commonly dries different species of eucalypt in a same load because of the difficulty of identifying the species, hybrids and clones, and also by optimizing the use of the kiln.

Micropropagation of an Eucalyptus hybrid (Eucalyptus benthamii x Eucalyptus dunnii) - doi: 10.4025/actasciagron.v33i4.8317

open access: yes, 2011
This study was designed to micropropagate E. benthamii x E. dunnii, by testing chlorine concentrations for explant asepsis, the optimal concentrations of benzylaminopurine (BAP) and naphthaleneacetic acid (NAA) for bud proliferation, and the ratio between BAP and gibberellic acid (GA3) in two nutrient media for shoot elongation. Nodal segments from H12,

EFFECT OF THE SAWING MODEL IN THE SAWNWOOD QUALITY OF Eucalyptus grandis AND Eucalyptus dunnii

open access: yes, 2015
This paper presents the results of a research carried out to evaluate the defects caused by growth stresses on boards produced from Eucalyptus grandis and Eucalyptus dunnii, using two different sawing models. Logs tested came from fast growing plantations belonging to two diametric classes.

Dynamics of adventitious rooting in mini-cuttings of Eucalyptus benthamii x Eucalyptus dunnii=Dinamica de enraizamento adventício em miniestacas de Eucalyptus benthamii x Eucalyptus dunnii

open access: yesActa Scientiarum: Agronomy, 2012
It is possible to determine the optimum time for permanence of vegetative propagules (mini-cuttings) inside a greenhouse for rooting, and this value can be used to optimize the structure of the nursery. The aim of this study was to determine the dynamics of adventitious rooting in mini-cuttings of three clones of Eucalyptus benthamii x Eucalyptus ...

Polyploid induction of Eucalyptus dunnii Maiden to generate waviability in breeding programs. [Polyploid induction of Eucalyptus dunnii Maiden to generate variability in breeding programs].

open access: yes, 2022
Eucalyptus dunnii Maiden produces good quality cellulose pulp, showing good frost tolerance. However, in Uru-guay, it needs more than six years to reach the reproductive stage. Genome duplication was proposed as a strategy to obtain useful variability. The application of mitosis inhibitors for chromosomal duplication, in explants growing in vitro, was ...

Avaliação das propriedades mecânicas de painéis compensados de Eucalyptus dunnii e Eucalyptus dunnii/Pinus taeda

open access: yes, 2015
A utilização do eucalipto vem crescendo no Brasil em vários setores de processamento de madeira. A apreensão em relação à falta de matéria-prima, no sul do Brasil, faz com que o eucalipto seja uma alternativa para substituição ou utilização conjunta com pinus, para a fabricação de painéis compensados.

QUALITY OF SAWN TIMBER DRYING OF Eucalyptus dunnii

open access: yesCiência Florestal, 2009
In the present study, the behaviour of Eucalyptus dunnii wood drying in a conventional pilot kiln was evaluated, using three drying schedules. Each drying schedule had an initial vaporization (presteaming) of 3 hours after one hour of initial warming and an intermediate vaporization of 5 hours for the collapse recovery when the wood was at 17% of ...
