بیماری زوال و خشکیدگی سرشاخه، مهمترین بیماری درختان اکالیپتوس در استان خوزستان است. برای بررسی مقاومت گونههای مهم اکالیپتوس، از میان گونههای موجود، چهار گونه و یک پروونانس شامل Eucalyptus camaldulensis, E. camaldulensis 9616, E. sargentii, E. microtheca, E. gillii که دارای صفات مطلوبتری بودند، به دو روش شاخههای بریده شده در آزمایشگاه و آلوده کردن نهالها در گلخانه مورد ارزیابی قرار گرفتند. ...
This study assessed the moulding, drilling, turning, sanding, and routing properties of seven plantation-grown hardwood species from southeast Australia to evaluate their potential as a resource for the manufacture of high quality furniture and furnishings. Eucalyptus grandis, Eucalyptus saligna, Corymbia maculata, Eucalyptus camaldulensis, Eucalyptus sideroxylon, Eucalyptus cladocalyx, and Euc...
Many species of the genus Eucalyptus from the Myrtaceae family are used in Brazilian folk medicine for the treatment of various medical conditions such as cold, flue, fever, and bronchial infections. In the current investigation, we evaluated the analgesic and anti-inflammatory effects of essential oil extracts from three species of Eucalyptus employing various standard experimental test models...
Seedling regeneration after a high intensity wildfire was assessed in a mixed forest dominated by Eucalyptus species andCallitris endlicheri (Parl.) F.M.Bailey. Patternswere compared against the ‘slow seedling’or ‘tortoise-and-hare’ theory of competitive interactions betweengymnosperms andangiosperms.Browsing effectswere documentedusing fenced plots, and seedling density, mortality and height w...
Eucalyptus is the second most planted tree on earth. Despite this ranking, its mature breeding programs, clonal propagation and deployment and short rotation time make it a leading target for biotechnology improvement. The recently completed eucalyptus genome project provides an enormous opportunity for understanding and developing new traits for eucalyptus forestry. The main obstacle for wides...
Eucalyptus plantations are frequently used for the establishment of bee yards. This study was carried on at Fazenda Brejão, northwestern region of the State of Minas Gerais, Brazil. This farm is covered both with native Cerrado vegetation (Brazilian savanna) and eucalyptus plantations. This paper reports on the botanic origin of pollen pellets and honey collected from honeybee (Apis mellifera) ...
در این تحقیق برگهای پنج گونه اکالیپتوس به نامهای eucalyptus microtheca f. muell، e. gongylocarpa blakely، maiden e. gillii، maiden e. woodwardi وe. salubris f. muell در فصل بهار، از دو نقطه در استان خوزستان (شوشتر و دزفول) جمع آوری شد و پس از خشک شدن در محیط آزمایشگاه، به روش تقطیر با آب، مورد اسانس گیری قرار گرفت. سپس ترکیب های تشکیل دهنده اسانس ها با استفاده از کروماتوگرافی گازی تجزیه ای (ana...
Dear Sir, We read the excellent short review article of Higgins et al. (1) on contact allergy to and the safety of eucalyptus oil with great interest. Having recently finished writing a full literature review of contact allergy to and the chemical composition of essential oils (2), we would like to give some additional information on eucalyptus oil. Also, we will address the question raised by ...
The replacement of diverse deciduous forests by eucalyptus plantations changes the timing, quality and quantity of litter inputs to streams, which has the potential to affect the activity of decomposers and thus ecosystem functioning. Here, we compared (a) the decomposition rate of alder and oak leaves incubated in deciduous and eucalyptus streams in Spain and Portugal, (b) the activity (fungal...
