 As unlikely as it may sound, plants appear to be capable of learning and decision-making. Yes, plants. For centuries, scientists have assumed such abilities were restricted to the animal kingdom. After all, plants don't have brains. But recent research is changing this view. Working with pea plants, an international team of scientists set out to test the hypothesis that plants have the capacity to learn by association. To do this, they constructed a simple Y-shaped maze. During a training period, as seedlings grew into the maze, they were exposed first to wind, a neutral, conditioning cue, followed by light, used as the type of reward. This was repeated on different arms of the maze for three consecutive days. This setup allowed the research team to ask the question, can plants learn to predict the position of the light based on the direction of the wind? In the first experimental group, wind and light were presented on the same side of the maze. When the seedlings had reached the split, the fan alone was turned on. In 62% of these cases, the plants grew toward the fan, despite the absence of light. Had they learned that growing toward wind would give them a better chance of finding light? Had they made a choice, in hope of a sunny reward? To find out, the team conducted a second experiment. This time, the fan and the light were placed on opposite arms of the maze. After this training session, when the fan was turned on, 69% of the seedlings grew away from the wind, suggesting that the plants had indeed formed an association between the position of the fan and the direction of the light. These experiments indicate that plants not only have the capacity to learn, but also to make choices based on a predicted outcome, all without a central nervous system. These findings are sure to further the debate over plant cognition and open the door for future research in this fascinating field.
