Patterns of carbon (C) allocation across different stages of stand development in Eucalyptus urophylla × E. grandis plantations are not well understood. In this study, we examined biomass and mineral soil C content in five development stages (1, 2, 3, 4–5, and 6–8 years old) of a Eucalyptus stand in southern China. The tree biomass C pool increased with stand age and showed a high annual rate o...

Eucalyptus oil possesses a wide spectrum of biological activity, including anti-microbial, fungicidal, herbicidal, acaricidal and nematicidal properties. We studied anti-fungal activities of the leaf oil extracted from Eucalyptus. grandis × E. urophylla. Eleven plant pathogenic fungi were tested based on the mycelium growth rates with negative control. The results showed that Eucalyptus oil has...

Background Agrobacterium mediated gene transfer technology offers the potential to introduce novel, high-value traits into selected, elite tree genotypes. Significant progress has been made in the regeneration and genetic transformation of Eucalyptus trees, but transformation efficiency has generally been low for eucalypts [1], especially for elite clonal genotypes. As a preliminary step toward...

The toxicity of aqueous extracts of two plants, Nicotiana tobacum and Eucalyptus globulus were investigated against second instar larvae of Lycoriella auripila, one of the most important pests of button mushroom, using agar dilution technique. Seven concentrations of aqueous extracts of both plants were applied on second instar larvae and their mortality were evaluated after 24, 48 and 72 h. Th...

In this work, a xylanase-producing strain, Streptomyces griseorubens LH-3, was cultured, and the crude xylanase was prepared. Analysis of its enzymatic properties revealed that the crude xylanase possessed good thermal stability at temperatures below 60 o C, exhibited a wide pH range from 4.0 to 9.0, and was cellulase-free. This crude enzyme was used to treat eucalyptus kraft pulp, and the rele...

Decomposition of three leaf species (Alnus glutinosa, Eucalyptus globulus and Quercus robur) were examined in a headstream. During two months decomposing leaves were periodically analysed for nutrient content, soluble sugars, phenols, protein precipitation capacity, total fiber, weight loss, microbial and macroinvertebrate colonisation. The leaves of the three species showed similar patterns in...

In a greenhouse trials, the effects of arbuscular mycorrhizae fungi (AMF) on growth and uptake of N, P, K and Pb by Eucalyptus rostrata L., grown with or without Phaseolus vulgaris, in lead (Pb) contaminated soil were investigated. Inoculation of the host plants with AMF, Glomus deserticola spores, significantly increased the dry weight, shoot length, total N, P and K as well as chlorophyll con...

Cloud Computing is a paradigm that dynamically provides resources as services through the Internet. The constant concern about the trust placed in cloud computing systems inspires dependability studies. A possible way of performing dependability studies, especially regarding reliability and availability, is through fault injection tools, which enable to observe the system’s behavior during the ...

The moss flora of Akdağ Mountain (Amasya, Turkey) was investigated. At the result of identifications of 1500 moss specimens, collected from the research area, 178 taxa belonging to 69 genera and 26 families were determined. Among them, 94 taxa are new for A3 grid square according to the Turkey grid system which was adopted by Henderson. The location data of Grimmia crinitoleucophaea Cardot and ...

A new type of wood plastic composite, Eucalyptus/PES(Polyethersulfone) blend, was developed. It was designed to be used in LS (Laser Sintering) with reduced energy usage with cost savings. The preparation of Eucalyptus/PES blend and part sintering were under fixed processing conditions and parameters. Through mechanical testing, it was discovered that the strength of prototypes is low due to th...
