Floral scent of artificial hybrids between two Schiedea species that share a moth pollinator.

ABSTRACT:

Premise

In flowering plants, pollinators' ability to recognize chemical displays of hybrids may erode reproductive barriers. Hybrids may produce novel or altered floral scent blends that are unattractive, or scents similar to either parent that remain attractive and promote backcrossing. We characterized the floral scent of hybrids of sympatric species with a shared pollinator and tested whether scent is sufficient for pollinator attraction.

Methods

Floral volatiles of artificial F₁ hybrids between Hawaiian Schiedea kaalae and S. hookeri (Caryophyllaceae) were characterized by dynamic headspace sampling and GC-MS. Behavioral choice tests with the native moth Pseudoschrankia brevipalpis measured the effect of adding S. kaalae scent (with flowers bagged to remove vi
