Plants can communicate each other through sounds; Research

Corn plants

Plants can talk with each other not only through signals but also by making “clicking” sounds.

This research has been published online in the March 22 issue of the journal Trends in Plant Science.

This research also shows that the plants not only respond to sounds but also produce sounds to communicate with each other.

Previously, it was known that plants like cabbage can spread volatile gases, such as methyl jasmonate, to warn the surrounding cabbage plants about some types of herbivores or annoying things like caterpillars.

“Everyone knows that plants react to light, and scientists also know that plants use volatile chemicals to communicate with each other, for instance, when danger – such as a herbivore – approaches,” Dr. Monica Gagliano said in a university news release.

So, the researchers from The University of Western Australia used powerful loudspeakers and listened sounds from the roots of the corn saplings. On the further note, researchers from The Bristol University found that the plants started to grow towards the source of sound, when they suspended the roots in water and played a continuous voice at 220Hz, which is the same as the plants produce.

“It is very likely that some form of sensitivity to sound and vibrations also plays an important role in the life of plants,” she added.
