Plants React to Vibration Sound, says Study
A new research done by Heidi Appel who is a senior research scientist in the Division of Plant Sciences at Missouri University stated that the plants are able to distinguish between feeding vibrations from other common sources of environmental vibration. Further he and his team discovered as to why certain plants react to sound.
There is a debate over the fact that music helps or harms plant life. Earlier researchers have proved that plants react to sounds for sure. What remained a mystery was the fact that plants have been around on earth from a time much earlier than the discovery of music, rock or classical so, how exactly do plants determine this music.
For the study Appel placed caterpillars on Arabidopsis, a small flowering plant and by using laser along with a small piece of reflective material researchers were able to measure the movement of the leaf in response to the caterpillar. They then played back recordings of caterpillar feeding vibrations to a first set of plans and played nothing to the second set.
To the surprise it was found out that the first set of plants that were aware that the caterpillars were coming produced an increased level of mustard oils in order to repel the caterpillars.
This particular experiment was published in the journal Oecologia and concluded that the vibrations produced by feeding insects are probably the quickest method plants have to detect insect attack. This research was funded in parts by the National Science Foundation.
