Abstract [en]

Differences in floral color and scent can affect pollinator behavior, creating assortative mating

between flowers. For plants where genome duplication leads to different cytotypes

(polyploids), floral traits could promote coexistence and speciation. I used GCMS analysis

and optical spectrometry to test for differences in floral scent and color of greenhouse grown

North American diploid and tetraploid fireweed Chamerion angustifolium. 25 volatile

compounds were identified in the scent analysis, of which 10 differed significantly between

diploids and tetraploids. Floral color differed with ploidy as well, with tetraploids having a

higher brightness than diploids. However, a Bombus terrestris visual sensory model indicated

that this species could not discriminate between the cytotypes based on color differences.

Based on these data, it seems likely that differences in floral scent traits could contribute to

pollinator discrimination between the cytotypes, which could help explain the pollinator

mediated assortative mating observed in previous studies.
