“Don´t! That hurts the plant.”
How many times haven´t you said this to a little one, yanking on the leaves of a plant?
Known as Plant perception or biocommunication it is the response of plants to sense and react to the environment to adjust their morphology, physiology, and phenotype accordingly.
The first record of this idea was back in 1848, by the German experimental psychologist Gustav Fechner, he suggested plants are capable of emotions and that one can promote a healthy growth by talking to them, providing them attention, a good attitude and affection.
Even when plants lack a nervous system, organs within the plant are sensitive and respond to stimuli.
There is controversial literature out there, of people that state plants just grow not caring about anything just doing what they are supposed to do.
I believe in plant intelligence just as I belive that we are all connected as the tree in Avatar, Eywa, Gaia, Great Spirit, God, the Spider Web of Life , how ever you like to call it.
Personally, my plants are my thermometer, I have observed them react to my emotional state.
