Researchers at McMaster University have found that plants become competitive when forced to share a pot with strangers of the same species, but they are more friendly when potted with their siblings. Because differences between groups of strangers and groups of siblings only occurred when they shared a pot, the root interactions may provide a cue for kin recognition. Though they lack cognition and memory, Dr. Susan Dudley, associate professor of biology, says the study shows plants are capable of complex social behaviors such as altruism towards relatives. Gdeners might want to use this discovery to change their plant arrangements, placing siblings close to one another.But, how the plants learn which neighbor is a relative is still a mystery. 全文及图片详见 ENS -- My left brain has nothing right.
