oil from the eucalyptus tree ( eucalyptus camaldulensis l.) is used today in many over the counter cough and cold products, to relieve congestion. eucalyptus oil is also used in creams and ointments to relieve muscle and joint pain, and in some mouthwashes. in this study eucalyptus camaldulensis leaves extracted with water and ethanol 96°and the antimicrobial effects of extracts were evaluated ...

Tree growth, biomass productivity, litterfall mass and nutrient content, changes in soil chemical properties and understory forest succession were evaluated over a 8.5-year period in singleand mixed-species (50 : 50) plantations of two N2-®xing species, Casuarina equisetifolia and Leucaena leucocephala, and a non-®xing species, Eucalyptus robusta. At the optimal harvest age for maximum biomass ...

starch is found in abundance in nature and it is one of the raw materials used for food packaging because of the low price, biodegradability, good mechanical and barrier properties. the recycling ability of coating materials was significantly increased by using edible films and coating in comparison to traditional packaging and it could be an alternative for synthetic films. in this research, t...

Two spotted spider mite (TSSM), Tetranychus urticae Koch, is an important pests on bean in Markazi Province (center of Iran). To evaluate the bioacaricidal activity of extracts of three essential oils of thyme (Thymus vulgaris), lavender (Lavandula officinalis)  and eucalyptus (Eucalyptus camaldulensis) against T. urticae on cherry bean (Vigna unguiculta subsp. sinensis), five different concent...

Within a single site in the Kohala Forest Reserve, Hawai‘i, we examined composition and diversity of soil microbial communities under four introduced (Cryptomeria japonica, Casuarina equisetifolia, Araucaria columnaris, and Eucalyptus sp.) and one native (Metrosideros polymorpha) canopy tree species, as well as pasture. Terminal restriction fragment length polymorphism (T-RFLP) analysis of soil...

Rust is a major Eucalyptus spp. disease, which is especially damaging for early-stage plants. The aim of this study was to verify the pre-infection process of Austropuccinia psidii (A. psidii) in the leaves of three phenological stages of Eucalyptus clones with different resistance levels. Plants from the hybrids of Eucalyptus urophylla × Eucalyptus grandis (E. grandis) with variable levels of ...

Because of its resistance to antibiotics, Staphylococcus aureus causes many of problems in hospital and society. As one of the main reasons of clinical infections it can cause to serious surgical and cutaneous infections and pneumonia. The inhibitory effect of the essential oils include; Eucalyptus largiflorence, E. camaldulensis, E. malliodora and E. polycarpa as a natural and herbal antimicro...

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...
