Drying Characteristics of Eucalyptus urophylla × E. grandis with Supercritical CO₂. [PDF]

Materials (Basel), 2020
Supercritical CO2 (ScCO2) is a drying medium with excellent solubility and mass transfer efficiency. Supercritical CO2 drying (SCD) can remove the water of wood rapidly and prevent a change of microstructure caused by capillary tension in the drying process. In this study, Eucalyptus urophylla × E.

The Abundance and Population Dynamics of Leptocybe invasa (Hymenoptera: Eulophidae) Galls on Eucalyptus spp. in China

Journal of Integrative Agriculture, 2012
The blue gum chalcid, Leptocybe invasa Fisher & La Salle, invaded China in 2007 and has subsequently caused substantial damage to eucalyptus trees. In the current paper, we investigated the susceptibility of 10 Eucalyptus spp. and Eucahetus dunnii to

PHYSICAL-MECHANICAL CHARACTERIZATION OF Eucalyptus urophylla WOOD [PDF]

Engenharia Agrícola, 2017
ABSTRACT: Eucalyptus urophylla consists in a wood-producing species, which offers a natural multiple raw material of good quality for applications in rural and civil constructions. However, Eucalyptus urophylla still has a small utilization as building parts and elements, resulting from the possible ignorance and low diffusion of its structural ...

Improved Estimates of Biomass Expansion Factors and Root-To-Shoot Ratios: An Approach for Different Forest Types Across a Climatic Gradient in Brazil. [PDF]

Glob Chang Biol
This paper addresses the global greenhouse gas inventory challenge by reducing uncertainty and enabling more reliable carbon accounting to support strategic and policy decision‐making under climate variability. ABSTRACT Advancements in the current state of the art of the key drivers of biomass expansion factor (BEF) and the root‐to‐shoot ratio (R) are ...

Microsporogenesis and flower development in Eucalyptus urophylla × E. tereticornis. [PDF]

Breed Sci, 2015
We compared microsporogenesis and flower development in Eucalyptus urophylla × E. tereticornis. In this study, although microsporogenesis and cytokinesis occurred simultaneously during meiosis of pollen mother cells, we observed a strong asynchronism in different anthers from a flower bud.

Organellar carbon metabolism is co-ordinated with distinct developmental phases of secondary xylem [PDF]

, 2019
Subcellular compartmentation of plant biosynthetic pathways in the mitochondria and plastids requires coordinated regulation of nuclear encoded genes, and the role of these genes has been largely ignored by wood researchers. In this study, we constructed
