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...
اکالیپتوس یکی از جنس‌های درختی و درختچه‌ای خانواده مورد (Myrtaceae) محسوب می‌شود که بومی استرالیا بوده و گونه‌های مختلف آن در سایر نواحی گرمسیری جهان یافت می‌شود. هدفاز این تحقیق، استخراج و شناسائی ترکیبهای شیمیائی اسانس گل‌های سه گونه از جنس اکالیپتوس کاشته‌شده در منطقه کاشان (E. largiflorens، E. torquataو E. loxophleba) می‌باشد. اسانس‌گیری به روش تقطیر با آب و با د...
Mycosphaerella ambiphylla sp. nov. (anamorph: Phaeophleospora) and Mycosphaerella aurantia sp. nov., are described from diseased Eucalyptus globulus leaves. In addition, a new fungal record in Australia, M. mexicana, and two new records for Western Australia, M. gregaria and M. parva, are discussed. A key is provided to Mycosphaerella species on E. globulus in Western Australia.
Novel species of fungi described in this study include those from various countries as follows: Australia: Apiognomonia lasiopetali on Lasiopetalum sp., Blastacervulus eucalyptorum on Eucalyptus adesmophloia, Bullanockia australis (incl. Bullanockia gen. nov.) on Kingia australis, Caliciopsis eucalypti on Eucalyptus marginata, Celerioriella petrophiles on Petrophile teretifolia, Coleophoma xant...
In this study, the application of eucalyptus essential oil/vapour as beverages preservative is reported. The chemical composition of eucalyptus oil was determined by gas chromatography-mass spectrometry (GC-MS) and solid phase microextraction GC-MS (SPME/GC-MS) analyses. GC-MS revealed that the major constituents were 1,8-cineole (80.5%), limonene (6.5%), α-pinene (5%), and γ-terpinene (2.9%) w...
Endogenous viral elements (EVEs) are the result of heritable horizontal gene transfer from viruses to hosts. In the last years, several EVE integration events were reported in plants by the exponential availability of sequenced genomes. Eucalyptus grandis is a forest tree species with a sequenced genome that is poorly studied in terms of evolution and mobile genetic elements composition. Here w...
