Plant Intelligence

From the Web

From an article by Sarah Griffiths in the Daily Mail published on January 17, 2014.

Researchers at the University of Western Australia examined the fern-like Mimosa pudica’s short and long-term memories under both high and low light environments by repeatedly dropping water on the plant using a custom-designed apparatus to look at the response. The plant, when touched, folds inwards to protect from predators.

The study, which also involved Professor Stefano Mancuso at the University of Florence in Italy, found the action is not simply a reflex.

The plant stopped curling up once it learned that the water was not a threat to its survival and no damage was done.

Mimosa pudica is also called the sensitive plant, sleepy plant and the touch-me-not, and is native to South America and Central America.

The plants were able to acquire the learnt behaviour in a matter of seconds and as in animals, learning was faster in low light. The study shows that Mimosa pudica plants can learn and remember just as well as it would be expected of animals, but they do it all without a brain.

“Most remarkably, these plants were able to remember what had been learned for several weeks, even after environmental conditions had changed,” the researchers said.
