Eucalyptus benthamii is an important species used in monoclonal and hybrid forest plantations around the world. Few natural populations of remain, as such it has been placed on list endangered species. We sampled 111 seeds from nine progenies across two provenances (Candói - progenies; Vale do Corisco seven progenies). Samples were genotyped using 19 microsatellite loci. A high number alleles (...

The capacity for nitrate reduction, as measured by nitrate reductase activity (NRA), was generally low for a range of plant communities in Australia (coastal heathland, rainforest, savanna woodland, monsoon forest, mangrove, open Eucalyptus forest, coral cay open forest) and only a loose relationship existed between NRA and leaf nitrogen concentration. This suggests that nitrate ions are not th...

Eucalyptus species are the most widely hardwood planted in the world. It is one of the successful examples of commercial forestry plantation in Brazil and other tropical and subtropical countries. The tree is valued for its rapid growth, adaptability and wood quality. Wood formation is the result of cumulative annual activity of the vascular cambium. This cambial activity is generally related t...

ABSTRACT This study aimed to evaluate the influence of commercial thermal treatment on Eucalyptus grandis considering its physical, chemical, and mechanical properties. The wood samples were heat-treated in an autoclave with saturated steam pressure application at four different temperatures: 155, 165, 175, 185 ºC. properties altered due heat treatment. extractives content varied between 6.06% ...
