یکی از روشهای تکثیر گیاه اکالیپتوس(eucalyptus camaldulensis dehnh) از طریق قلمه است. با این وجود قلمه های این گیاه به راحتی ریشه دار نشده و معمولاً نیاز به تیمارهای هورمونی ویژه دارند. در یک پژوهش گلخانهای بهمنظور بررسی برهم کنش هورمون اکسین و روش تغذیه کودی در فرایند ریشهزایی، تأثیر غلظت های مختلف iba و دو نوع کود زیستی (بارور و نیتروکسین) به همراه کود محلول معدنی (شیمیایی) بر ریشه زایی قل...
PURPOSE This study was conducted to assess the effect of skin pre-treatment with Transcutol(®) and eucalyptus oil on systemic absorption of topical trolamine salicylate in rat. METHODS Pharmacokinetic parameters of salicylic acid following administration of trolamine salicylate on rat skin pre-treated with either Transcutol(®) or eucalyptus oil were determined using both non-compartmental and...
In Egypt, the River Red Gum (Eucalyptus camaldulensis) is a well-known tree and is highly appreciated by the rural and urban dwellers. The role of Eucalyptus trees in the ecology of Cryptococcus neoformans is documented worldwide. The aim of this survey was to show the prevalence of C. neoformans during the flowering season of E. camaldulensis at the Delta region in Egypt. Three hundred and ele...
Novel species of fungi described in this study include those from various countries as follows: Antarctica: Cadophora antarctica from soil. Australia: Alfaria dandenongensis on Cyperaceae, Amphosoma persooniae on Persoonia sp., Anungitea nullicana on Eucalyptus sp., Bagadiella eucalypti on Eucalyptus globulus, Castanediella eucalyptigena on Eucalyptus sp., Cercospora dianellicola on Dianella sp...
The application of Cd inhibited the development of mycelia of the saprobe fungi Fusarium concolor and Trichoderma koningii and the hyphal length of the arbuscular mycorrhizal fungi Glomus mosseae and G. deserticola in vitro. The application to soil of 25 and 50 mg l–1 of Cd decreased the shoot dry weight, the percentage of AM root length colonization and the succinate dehydrogenase activity of ...
Background Eucalyptus is grown in around 3.9 Mha in India. Leptocybe invasa Fisher & La Salle (Hymenoptera: Eulophidae) has emerged as a serious pest in Eucalyptus causing considerable loss of quality planting materials besides loss in productivity and quality of timber. Current strategies for its control include selected deployment of Eucalyptus clones tolerant to the pest resulting in several...
A small but intense eucalyptus research effort began in Florida in 1961 with the private, nonprofit Florida Forests Foundation dedicated to investigating the commercial forestry potential of exotic hardwoods in south Florida. By 1965 we had established numerous eucalyptus experiments, including 14 screening trials testing a total of 156 seed sources representing 67 eucalyptus spe cies. The Fou...
Eucalyptus is a diverse genus of flowering trees and shrubs in the myrtle family, Myrtaceae. Different chemical constituents such as Sideroxylonal C, (+)-oleuropeic acid, cypellocarpins A, B and C, cypellogins A, B and C, Leptospermone, Isoleptospermone, grandinol, various essential oils and many others have been isolated from plants of eucalyptus genus. Various eucalyptus species have been rep...
The leaves of four cultivated Eucalyptus species, Eucalyptus microtheca var. Microtheca F. Muell., Eucalyptus spathulata, Eucalyptus largiflorens and Eucalyptus torquata were collected in spring from Kashan and Isfahan provinces (central region of Iran). After drying the plant materials in shade, their essential oils were obtained by hydro-distillation. The oils were analyzed by capillary gas c...
جنگلهای طبیعی پده که در حاشیه رودخانه‌های استان خوزستان عرصه وسیعی را پوشانده‌اند، با تخریب فراوان مواجه می‌باشند. بدین‌ترتیب جنگل‌کاری ممکن است راه‌حل مناسبی برای احیای این بیشه‌زارهای تخریب یافته باشد. کاشت گونه‌های Eucalyptus camaldulensis، Acacia salicina و Dalbergia sissoo در قالب طرح بلوک‌های کامل تصادفی با سه بلوک در سال 1372 در حاشیه رودخانه دز صورت گرفت. برای ارزیابی ماکروفون خاک در ا...
