Combining ability of elite clones of Eucalyptus grandis and Eucalyptus urophylla with Eucalyptus globulus

Genetics and Molecular Biology, 2007
In Brazil, eucalyptus breeding programs for cellulose production has used two species, Eucalyptus grandis and Eucalyptus urophylla. Nevertheless, it would be useful to introgress alleles from other species to improve wood quality and volume.

Genetic control of Eucalyptus urophylla and E. grandis resistance to canker caused by Chrysoporthe cubensis

Genetics and Molecular Biology, 2010
Chrysophorte cubensis induced canker occurs in nearly all tropical and subtropical regions where eucalypts are planted, causing losses in both wood quality and volume productivity, especially so in the warmer and more humid regions of Brazil.

CHEMICAL AND ENERGETIC CHARACTERIZATION OF Eucalyptus grandis × Eucalyptus urophylla CLONES SUBJECT TO WIND DAMAGE

Revista Árvore, 2019
Wind damages are common in forest plantations and the use of this wood can minimize losses. The objective was to evaluate the chemical composition and the energetic potential of wood and charcoal from trees subject to wind damage.

Comparison Between Open Pollinated Progenies and Hybrids Performance in Eucalyptus grandis and Eucalyptus urophylla

, 2006
Summary The cellulose industry in Brazil uses, mainly, hybrids between Eucalyptus grandis × E. urophylla. Not only the volume but also the wood density has great influence in the cellulose productivity, therefore a selection for both characteristics ...

Retenção e penetração de cca em madeira de primeira e segunda rotação de Eucalyptus urophylla S.T. Blake

Ciência Florestal, 2013
This study aimed to evaluate the retention and penetration of copper chrome arsenate (CCA type C) as well as some wood properties of two rotations of two natural hybrid of Eucalyptus urophylla S. T. Blake, aiming their use as treated wood. The study was conducted with material from commercial plantations, with 63 months of age.
