Background The genus Eucalyptus is the most important planted tree to the Brazilian economy. Besides being a source of timber, its wood pulp is mostly used for papermaking. There is a considerable interest in its genetic improvement due to the economic importance of the gender to forestry companies. The time required to obtain ideal populations, after selective breeding, is a limiting factor of...

Enzyme-inducing and cytotoxic effects of South African bedding materials were investigated using a mouse hepatoma cell line, Hepa-1, cell culture system. This cell culture system is a convenient and sensitive method for the screening of bedding materials for the presence of compounds that could be potentially harmful to animals and thus the experimental outcome. Cells were exposed to acetone ex...

Background Eucalypt canker disease (Chrysoporthe cubensis) was the main driver of the concept of eucalypt clonal forestry in Brazil. Initially clonal forestry was based on outstanding spontaneous hybrids resistant to canker disease. Since the recognition that cloning superior inter-specific hybrids could be an important general strategy, several crosses were made for many different purposes, es...

Common metrics for evaluating the efficiency of oxygen delignification include the kappa number and Klason lignin content. As a change in xylan content often leads to a change in HexA content, the kappa number must be corrected for the HexA contribution before evaluating the degree of oxygen delignification when trying to understand the process in detail. Questions could also be raised about th...

Eucalyptus is an exotic plant in Brazil, being originally from Australia. There are about 700 Eucalyptus species described and over 3,000 hybrids. It is one of the most planted tree genus in the world. The great economic interest on Eucalyptus trees is due to their fast growth, high productivity, great adaptability to different types of soils and climates, and also to the high versatility of th...
