TermDefinition
auxin (IAA)stimulates stem elongation, root growth, cell differentiation, and branching; regulates development of fruit; enhances apical dominance; functions in phototropism and gravitropism; promotes xylem differentiation; retards leaf abscission
cytokininsaffect root growth and differentiation; stimulate cell division and growth; stimulate germination; delay senescence
gibberellinspromote seed and bud germination, stem elongation, and leaf growth; stimulate flowering and development of fruit; affect root growth and differentiation
brassinosteroidsinhibit root growth; retard leaf absciccion, promote xylem differentiation
abscicic acidinhibits growth; closes stomata during water stress; promotes seed dormancy
ethylenepromotes fruit ripening, opposes some auxin effects; promotes or inhibits growth and development of roots, leaves, and flowers, depending on species
