Intense studies on Genus Eucalyptus essential oil composition have been published already (Nair et al, 2008; Gamal and Sabrin, 2007; Batista-Pereira et al, 2006; Sartorelli et al, 2006; Hedges and Wilkins, 1991; Bignell et al, 1998).
Volatile Leaf Oils of some Queensland and Northern Australian Species of the Genus Eucalyptus. (Series II).
Volatile leaf oils of some south-western and southern Australian species of the genus Eucalyptus. Part I.
urophylla as well as in the hybrid urograndis are similar, and agree with the description of the genus Eucalyptus
(Metcalfe and Chalk, 1979; Metcalfe, 1987).
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.
Abstract: In 1998 the eucalyptus weevil, Gonipterus scutellatus (Coleoptera: Curculionidae), a major defoliator of the genus Eucalyptus
, which causes growth and economic losses, was detected in Chile.
Two articles deal with allelopathy in Australian plants: one considers the important genus Eucalyptus
, long considered to be involved in allelopathic interactions.
Consequently, 8 of 10 species with lower SLA had more leaf nitrogen per unit area, the exceptions being in the genus Eucalyptus
(in which the divergence in SLA was only slight) and in the genus Olearia, which was the only rainfall PIC that also went against the general trend to lower SLA at low rainfall.
Instead, the pattern in total gall species richness can largely be explained by the fact that myrtaceous tree species (of the genus Eucalyptus and the closely related genus Syncarpia) supported more gall species than other plant species (Fig.
As galling was concentrated in myrtaceous tree species (especially the genus Eucalyptus), the explanation of the results must lie in the reasons why there are more myrtaceous tree species at low-fertility sites, and why Myrtaceae such as eucalypts have so many associated gall species.
One of these medicinal plants, many species of the genus Eucalyptus from the Myrtaceae family are used in many parts of the world for the treatment of a wide variety of diseases including microbial infections (Ben Arfa et al, 2007).
The essential oil constituents of the genus Eucalyptus (Myrtaceae) have been well characterized (Batista-Pereira et al, 2006) Eucalyptus species produce numerous volatile compounds in large amounts, especially isoprenoids (here referred to as terpenes), which are accumulated in glands abundantly distributed throughout the leaf parenchyma and bark.
