چکیده انگلیسی
Floral scents are important olfactory signals for communication between plants and pollinators. Several studies have focused on inter-specific variation of floral scents, but little is known about the intra-specific variation, especially in some polychromic species. In this study, we investigated the floral scent compositions of Buddleja fallowiana and Buddleja officinalis in situ by dynamic headspace collection and coupled GC-MS. Variations of scent compositions within and between populations as well as among species were compared. In spite of substantial intra- and inter-population variability, B. fallowiana and B. officinalis were clearly differentiated in their scent profiles. In B. fallowiana, obvious differentiation was found between studied populations, while all investigated populations in B. officinalis are part of a metapopulation. These high intra-specific variations are discussed in relation to the introgression through hybridization and founder effects from different populations.
