This is an interesting study - I have not read the whole report but some of
you might tackle it:

Abstract
Can plants sense natural airborne sounds and respond to them rapidly? We
show that *Oenothera drummondii* flowers, exposed to playback sound of a
flying bee or to synthetic sound signals at similar frequencies, produce
sweeter nectar within 3 min, potentially increasing the chances of cross
pollination. We found that the flowers vibrated mechanically in response to
these sounds, suggesting a plausible mechanism where the flower serves as
an auditory sensory organ. Both the vibration and the nectar response were
frequency=E2=80=90specific: the flowers responded and vibrated to pollinato=
r
sounds, but not to higher frequency sound. Our results document for the
first time that plants can rapidly respond to pollinator sounds in an
ecologically relevant way. Potential implications include plant resource
allocation, the evolution of flower shape and the evolution of pollinators
sound. Finally, our results suggest that plants may be affected by other
sounds as well, including anthropogenic ones.
