Abstract in another language

The floral scent composition of 32 European and two Asian Salix L. species(Salicaceae) was analyzed. Intra- and interspecific variation was compared for a subset of8 species. All Salix species are dioecious and floral scent was collected from both male andfemale individuals by using a dynamic headspaceMicroSPEmethod, and analyzed by GC-MS.A total of 48 compounds were detected, most of them being isoprenoids and benzenoids.Commonly occurring compounds included trans-β-ocimene, cis-β-ocimene, benzaldehyde,D-limonene, α-pinene, cis-3-hexenyl aceatate, linalool, 1,4-dimethoxybenzene, and β-pinene.Two compounds, 1,4-dimethoxybenzene and trans-β-ocimene, were responsible for most ofthe interspecific variation. In a subset of eight extensively sampled species, six had acharacteristic floral scent composition; half of the pairwise species comparisons confirmedsignificant differences. In three of these eight species, intraspecific variability could beexplained by sex differences. Variation in Salix floral scent may provide specific signals thatguide pollinators and thus contribute to the reproductive isolation of compatible andcooccurring species.
