That Clicking Sound You Hear? It’s Your Plants Talking To Each Other.
Okay, now is the time to start getting really worried. It’s bad enough that not only are we looking toward the end of mankind thanks to some silly Mayan calendar and that we could be on the verge of a zombie apocalypse but it seems that our plants are actually talking to each other.
Just think, every time you go and pick that rose for your sweetheart or prune back that wild ivy they are letting the whole plant world know the cruelty that is being done to them.
Think I’m going off the deep end eh?
Well check this out, it seems that a scientist by the name of Monica Gagliano at the Exeter University has discovered that all those previously thought to be silent plants actually are communicating with each other using clicking sounds.
Along with fellow scientists Stefano Mancuso and Daniel Robert she used some very powerful acoustic equipment they could hear clicking sounds coming from the roots of corn saplings.
Gagliano and her team concluded that plants are indeed communicating with each other by making clicking sounds that travel easily through soil. It’s thought that, like the methyl jasmonate, these signals are warning of incoming threats.
The discovery shows that the role of sound in plants, a field of study referred to as bioacoustics, has yet to be fully explored and understood. It’s quite possible, notes Gagliano, that some form of sensitivity to sound and vibrations may also play an important role in the life of plants.
