Genomic of Eucalyptus globulus for pulp and biofuels
Eucalyptus is a species of great interest for the pulp and paper industry. Worldwide there are 20 million hectares planted and within Chile a total of 700.000 ha, being the main species grown for short-fibre pulp Eucalyptus globulus, which is extensively used for pulping due to its fast growth, high pulp yield, and good fiber properties. Genetic programs of this specie have been oriented in imp...
متن کاملEucalyptus Globulus
"The authentic facts, relating to the remarkable power of the Eucalyptus Globulus in drjing marsh lands and rendering them healthy, are such as to deserve serious and general attention. It appears to be certain that where the Eucalyptus prospers intermittent fever disappears. This tree grows with incredible rapidity, absorbs ten times its own weight of water in twentyfour hours, and spreads thr...
متن کاملPredicting extractives, lignin, and cellulose contents using near infrared spectroscopy on solid wood in Eucalyptus globulus
Near infrared reflectance (NIR) spectroscopy can be used to reliably predict both the physical and chemical wood properties of Eucalyptus. However, studies have been based on ground wood, which is costly and time-consuming to obtain. Predicting wood traits from NIR spectral data taken from solid wood would greatly increase the speed and cost-effectiveness of this procedure. Existing ground wood...
متن کاملLow temperature stress and changes in the lignin content and composition in Eucalyptus globulus
It is known that many abiotic stresses, such as mineral deficiency, drought, UV-B radiation, wind and low temperatures, alter the quantity and composition of lignin in several species [1]. The aim of this work was to verify if the cold stress may cause changes in the quantity and composition of lignin in E. globulus. Additionally, we analyzed whether these changes can also be beneficial from th...
متن کاملVariation of Wood Pulping and Bleached Pulp Properties Along the Stem in Mature Eucalyptus globulus Trees
The wood of a mature (40-year-old) Eucalyptus globulus Labill tree was characterized at different stem height levels (0%, 10%, 35%, and 50% of total height) regarding pulping, bleaching, and paper properties. Pulp yields increased upwards from 46% to 50%, and Kappa number decreased from 17.5 to 12.3 at 0 and 50% height, respectively. The estimated specific wood consumption ranged from 3.2 m odt...
