The major plant growth regulator are auxins, cytokinins, indoles and hormones. These PGRs present in seaweed are in very small quantities, generally measured in parts per million. It only takes a small amount of these to do the job. The cytokinins in seaweed extracts are a major factor when applied to apple and peach trees in promoting the growth of fruiting spurs and reduce premature dropping of fruit. They move to areas of cell elongation where they allow the walls of cells to stretch.
Auxins actually give fruits and vegetables a naturally longer shelf life.
