Plants Respond to Leaf Vibrations Caused by Insects’ Chewing, MU Study Finds from MU News Bureau on Vimeo.
Previous studies have suggested that plant growth can be influenced by sound and that plants respond to wind and touch. Now, researchers at the University of Missouri, in a collaboration that brings together audio and chemical analysis, have determined that plants respond to the sounds that caterpillars make when eating plants and that the plants respond with more defenses.
