In botany, Repulsion theory is a theory that is used to explain how plants regulate the distance between new budding leaves on a stem. The theory states that each leaf on a stem secretes a substance that inhibits growth of a new leaf. A new leaf will only grow a certain distance away from the previous leaf where the concentration of the substance reaches a lower level.[1] Although no inhibitors have yet been discovered, the theory is supported by several surgical and modeling experiments.[2]
