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...

نمونه های دو گونه اوکالیپتوس Eucalyptus stricklandii Maiden  و Eucalyptus erythrocorys F. Muell. که در منطقه شمال خوزستان کشت گردیده در اواسط اسفند 1382  جمع آوری و به روش تقطیر با آب (طرح کلونجر) اسانس گیری و سپس نمونه توسط دستگاههای کروماتوگرافی گازی (GC)  و کروماتوگرافی گازی متصل به طیف سنج جرمی (GC/MS) مورد تجزیه قرار گرفتند.   ترکیبهای عمده در گونه E. stricklandii Maiden  عبارتند از : 1,8-...

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...

Social wasp colonies can be transferred to agroecosystems in order to control pest populations. Some failures of such transfers are common because wasps may abandon the nest immediately after the colony’s transfer. Knowing the nesting habits of wasps in agroecosystems could improve the success of colony transfer during wasp management. Thus, we recorded social wasp nests in a eucalyptus plantat...

The ability of Trametes villosa laccase, in conjuction with 1-hydroxybenzotriazole (HBT) as mediator and alkaline extraction, to remove lignin was demonstrated during treatment of wood (Eucalyptus globulus) and non-wood (Pennisetum purpureum) feedstocks. At 50 Ug(-1) laccase and 2.5% HBT concentration, 48% and 32% of the Eucalyptus and Pennisetum lignin were removed, respectively. Two-dimension...

We examined the effects of polyphenols on the analysis of lignin by histochemical methods, namely, the Mäule color reaction coupled with microspectrophotometry and ultraviolet microspectrophotometry, in wood of Eucalyptus camaldulensis and E. globulus. Thin sections and wood meals were extracted with solutions of alkali at different concentrations. The amounts of alkali-soluble extractives incr...

In the worldwide search for new strategies in sustainable weed management, the use of plant species able to produce and release phytotoxic compounds into the environment could be an effective alternative to synthetic herbicides. Eucalyptus globulus Labill. is known to be a source of biologically active compounds responsible for its phytotoxic and allelopathic properties. Our previous results de...

Ceratocystis wilt, caused by Ceratocystis fimbriata, has become the most important disease in eucalyptus (Eucalyptus spp. and hybrids) plantations in Brazil. To further our understanding of the epidemiology of this disease, we surveyed eucalyptus plantations in the states of Minas Gerais and Bahia that were known to have Ceratocystis wilt or were thought to have been planted with infected roote...
