Organogenesis and transient genetic transformation of the hybrid Eucalyptus grandis × Eucalyptus urophylla Organogênese e transformação genética transiente do híbrido Eucalyptus grandis × Eucalyptus urophylla

open access: yesScientia Agricola, 2011
The hybrid Eucalyptus grandis x Eucalyptus urophylla presents high levels of productivity and potential for use in paper, cellulose and fiber industries. The bud organogenesis from leaf explants of two clones of E. grandis × E. urophylla was studied in order to verify the effect of several factors: subculture duration on multiplication medium, type of ...

Productivity and carbon allocation in monospecific and mixed-species plantations of Eucalyptus grandis and Acacia mangium in Brazil [PDF]

open access: yes, 2010
Nitrogen fertilizer inputs are required in fast growing eucalypt plantations to meet tree requirements, and to compensate for the large nitrogen outputs associated with wood exportation at the end of the short rotations. Due to the economic and potential

CARACTERIZAÇÃO DA FAUNA EDÁFICA EM PLANTIOS DE Eucalyptus spp.

open access: yesCiência Florestal, 2013
Forest soils provide good conditions for the development and the establishment of soil fauna, manly by the deposition of litter. However, monoculture systems conducted in a single food providing substrate, can promote the development of certain fauna ...

Competition for light and light use efficiency for Acacia mangium and Eucalyptus grandis trees in mono-specific and mixed-species plantations in Brazil [PDF]

open access: yes, 2010
Mixed plantations with N-fixing species might be an attractive option for limiting the use of fertilizer in highly productive Eucalyptus plantations. A randomized block design was set up in southern Brazil, including a replacement series and an additive ...

Air-drying of seven clones of Eucalyptus grandis × Eucalyptus urophylla wood

open access: yesBioResources, 2019
Selecting clones with the best genetic material is one goal of eucalyptus breeding programs. Understanding the variations between the wood from different hybrid clones during drying is necessary to process improvement. This study aimed to select eucalyptus clones for lumber production based on their drying defects. From a plantation in Brazil, 42 trees
