Background The genus Eucalyptus has many species that are well adapted to a wide range of environmental conditions in Brazil. However, in some areas diseases are a limiting factor, among which the Eucalyptus rust caused by Puccinia psidii Winter stands out as a destructive pathogen of the Myrtacea. The growth of plants with high levels of infection is severely compromised and these plants end u...

Eucalyptus globulus Labill is one of the most important economic forest species in Portugal, occupying an area of 875.10ha in a total forest area of 3346.10ha (Tomé et al., 2007). The main goal of this study is to develop a dominant height growth model for Eucalyptus, applicable throughout the country, representing an improve of the curves that are part of the whole stand model existing in Port...

The physicochemical characteristics of Libyan Eucalyptus honey were measured including: moisture with 18.00%, sugars (fructose; 40.00, glucose; 32.00%, sucrose; 1.50% & maltose; 4.70%), total proteins; 0.08%, total amino acids; 0.11%, total acidity; 25.00meq./gk, HMF; 4.60mg/kg, color; light amber, ash; 0.17%, total soluble solids; 82.00% and insoluble solids; 0.07%, and electrical conductivity...

The relationship between biodiversity and ecosystem function has received a great deal of attention in ecological research and recent results, from re-analyses, suggest that ecosystem function improves with increases in phylogenetic diversity. However, many of these results have been generalized across a range of different species and clades, and plants with different evolutionary histories cou...

OBJECTIVE To evaluate the in vitro antimicrobial activity of the Eucalyptus globulus essential oil, and of the xylitol and papain substances against the following microorganisms: Pseudomonas aeruginosa; Samonella sp.; Staphylococus aureus; Proteus vulgaris; Escherichia coli and Candida albicans. METHOD The in vitro antimicrobial evaluation was used by means of the agar diffusion test and eval...

Background The wide adaptability, fast growth rate, good form, excellent wood and fiber properties make Eucalyptus the most widely planted genus of plantation forest trees. With the availability of Eucalyptus genome sequence information, assignment of function to genes contributing to desired traits require functional validation via overexpression or silencing in the context of the plant enviro...

Natural dyes are gaining interest due their expected low risk to human health and to the environment. In this study, the wash fastness of a natural coloring matter from the liquid waste produced in the steam treatment of eucalyptus wood in textile fabrics was investigated. Specifically, eucalyptus wood extract was used to dye cotton, nylon and wool in an exhaust dyeing process without the addit...

Peroxidase and chitinase activities were measured in rnotsi of Eucalyptus ghhulus spp. bicustata {Wdid. et aL) Kirkp, during colonization by Pisolithus sp. isolated from under Eucalyptus. Ten fungal isolates, ranging from poor to good root colonizers, were selected to represent a range of ectomycorrhizal aggrfssi\'ity. The induction of chitinases and peroxidases was strongly related to the aggr...

Eucalyptus urograndis is a hybrid eucalyptus of major economic importance to the Brazilian pulp and paper industry. Although widely used in forest nurseries around the country, little is known about the biochemical changes imposed by environmental stress in this species. In this study, we evaluated the changes in the stem proteome after short-term stimulation by exposure to low temperature. Usi...
