Plants may not have eyes and ears, but they can recognize their siblings.
“Canadian researchers published in 2007 that sea rocket, a common seashore plant, can recognize its siblings — plants grown from seeds from the same mother.
Susan Dudley, an evolutionary plant ecologist at McMaster University in Hamilton, Ontario, and her colleagues observed that when siblings are grown next to each other in the soil, they “play nice” and don’t send out more roots to compete with one another.
However, the moment one of the plants is thrown in with strangers, it begins competing with them by rapidly growing more roots to take up the water and mineral nutrients in the soil.
Strangers planted next to each other are often shorter, Bais notes, because so much of their energy is directed at root growth.
Because siblings aren’t competing against each other, their roots are often much shallower.
Bais says he and his colleagues also have noticed that as sibling plants grow next to each other, their leaves often will touch and intertwine compared to strangers that grow rigidly upright and avoid touching.”
What say you about this? The fact that plants might have an idea of what’s happening around them is a little freaky and sad…
