“…26 Similarly, in a bioassay study with the generalist Spodoptera exigua. β-caryophyllene had a highly significant effect on mortality, 27 correlates with reduction in the level of lepidopteran herbivory in several populations of the tropical leguminous tree Hymenaea stigonocarpa 28 and attracts adult predatory green lacewings, Chrysopa carnea, 29 while Bernhad Weissbecker et al 30 demonstrated that the two-spotted predaceous stinkbug, Perillus bioculatus, was attracted towards the sesquiterpenes β-caryophyllene, germacrene D, bicyclogermacrene and α-humulene in volatiles released from damaged potato plant by Colorado potato beetle. By separating apolar terpenoid hydrocarbons from more polar compounds using column chromatography on silica, Wegener et al 31 showed that a volatile blend containing α-elemene, δ-cadinene, α-humulene, germacrene D and (E,E)-α-farnesene, emitted in jasmonate-induced elm leaves, was exploited by the specialist parasitoid Oomyzus gallerucae in locating its host, the elm leaf beetle Xanthogaleruca luteola.…”

Steam-distilled volatile oils from the leaves and flowers of Lantana camara L. were analysed by GC and GC-MS. The oils are characterized by a high percentage of sesquiterpenes. The main components detected are germacrene D (15.85%), β-caryophyllene (12.35%), α-humulene (9.31%) and germacrene-B (6.19%). 1,8-Cineole (4.61%), an oxygenated monoterpene is also reported. Experimental Plant Material and Extraction of VolatilesAerial parts of L. camara were collected from the campus of South China Agricultural University, Guangzhou, People's Republic of China, in August-September. Fresh leaves, flowers and thin branches were cut into 1-2 cm pieces, air-dried for 7 days at room temperature and steam-distilled for 5 h furnishing 0.13-0.2% (v/w) oils. The oils were dried over anhydrous Na 2 SO 4 and kept refrigerated until used. Analysis of the Essential OilsComponents of the volatile oil were separated on a Finnigan TRACE 2000 GC-MS instrument (FinniganSpectronex, USA), equipped with two fused-silica column (30 mm × 0.25 mm i.d.), coated with DB-1 (df = 0.25 µm); temperature programme, from 60°C (for 2 min) to 80°C at 3°C/min; 80-120°C at 6°C/min (held 0 min); 120-140°C at 3°C/min (held 0 min); then to 230°C at 10°C/min (held 0 min) and later, 240°C (held 1 min); injector temperature, 220°C; ion source temperature, 200°C; EI, 70 eV; carrier gas, He, 1 ml/min; injection volume, l µl; split, 1:20; mass range, 35-450 amu.

Decomposing litter provides critical nutrients for plants, particularly in nutrient-poor ecosystems such as tropical forests. We hypothesised that decomposing litter improves the performance of a variety of tropical tree seedlings, and that this litter effect varies depending on the species of litter present in litter mixtures. We addressed these hypotheses with a large pot experiment manipulating a range of different litter mixtures of contrasting quality and using seedlings of four tree species from the Amazonian forest of French Guiana. In contrast to our initial hypothesis, decomposing litter had either neutral or negative impacts on seedling growth, despite strongly different growth rates, biomass allocation patterns and leaf and root traits among tree species. Tree species varied in their responses to litter additions, which were further modified by species identity of the added litter. Our data show litter species-specific effects on growth, biomass allocation and leaf and root traits of tropical tree seedlings. These results suggest that a net nutrient release from decomposing litter does not necessarily improve tree seedling growth, even under nutrient-limiting conditions. In conclusion, litter layer composition may affect seedling establishment and recruitment success beyond litter-derived plant nutrient availability, which may contribute to tree species composition and dynamics in the studied tropical forest.

“…If the primary role of the volatile oil is in defense against fungal pathogens it is not clear why M. gale invests in such a complex mixture of Other factors may account, to some extent, for the composition of the oil. The success of insect herbivores is known to be adversely affected by monoterpenes (Annila & Hiltunen 1977;Cates & Redak 1986;Cates et al 1987;Mihaliak et al 1987) and sesquiterpenes (Langenheim et al 1980;Stipanovic 1986). However, verte-brate herbivores avoid M. gale foliage (Jackson 1977;Linklof et al 1974; R. R. Carlton pers.…”

The antifungal activity of the leaf gland volatile oil of sweet gale (Myrica gale) (Myricaceae)

et al. 1992

The antifungal activity of volatile oil obtained from the leaves of sweet gale (Myrica gale) has been investigated. Fungi, isolated from the leaves of M. gale, were grown in liquid medium containing the oil and its effect on biomass production was gauged. The oil inhibited growth of all species of fungi to greater or lesser extent. Sesquiterpenes were more active than monoterpenes, and among the sesqui-terpenes germacrone was marginally more active than 13-elemenone. These results support the proposition that the volatile oil of M. gale has a role in resistance to fungal pathogens.
