Can plants hear?

I remember an episode of Mythbusters where the team set up a few different greenhouses with different sound or lack of sound and found that the plants growing in the greenhouses with more sound generally grew better. A new study has just been released which shows that some flowers respond to pollinator sound within minutes by increasing nectar sugar concentration. You can read the full paper at:
