Plants Talk and Listen To Each Other, Communication Crucial for Survival

June 16, 2012

As a follow up to a few articles I’ve posted previously, here’s more on recent scientific findings related to plant communication…

When a South African botanist Lyall Watson claimed in 1973 that plants had emotions that could be recorded on a lie detector test, he was dismissed by many in the scientific community.

However, new research, published in the  journal Trends in Plant Science, has revealed that plants not only respond to sound, but they also communicate to each other by making “clicking” sounds.

Using powerful loudspeakers, researchers at The University of Western Australia were able to hear clicking sounds coming from the roots of corn saplings.

Researchers at Bristol University also found that when they suspended the young roots in water and played a continuous noise at 220Hz, a similar frequency to the plant clicks, they found that the plants grew towards the source of the sound.

“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. Gagliano said in a university news release.

    Great to see Western Australia (my home state) doing something to further horticultural knowledge…now if they can only start to put some effort in to dealing with the rising water tables that are threatening to take over most of the South West of the state with salinity problems there might still be some land left to plant out our newfound besties “The Corn” 😉
