Australian scientists have discovered plants have a hearing.
Scientists from the University of Western Australia found that plants are capable of using roots to respond to sounds to locate water, and also try to avoid certain noises.
This was reported on the website of the University.
Experiments have shown that plants can sense sound vibrations from the flow of water moving through the pipes or in the soil, so the roots stretch in the direction of the source of water. It was found that the plants do not like certain noises and move away from certain sounds.
As experimental model, we used pea (Pisum sativum), which was placed in a container with two tubes at the base. Thus the plant was a choice of two directions of root growth. Then scientists began to study its response to several sounds, including white noise, running water and recording the noise of running water.
It was found that plants accurately determine the water source based on feeling only the sound of running water, and their roots move in the direction of this source. When the soil was sufficiently moist, the plant on the sound of water did not react.
“This indicates that the invasion of tree roots into the sewer can be based on the fact that the plant “hears” the water, but it also shows that their perception of the environment a lot more and much more complicated than we thought earlier,” said Dr. Monica Gagliano from the Centre for evolutionary biology.
Because so far, it was decided to explore the negative acoustic impact on the population of animals in connection with the new discovery, scientists consider it necessary to expand this program to the plants.
