• Stimulates differentiation of phloem and xylem 

• Stimulates root initiation on stem cuttings and lateral root development in tissue culture 

• Mediates the tropistic response of bending in response to gravity and light 

• The auxin supply from the apical bud suppresses growth of lateral buds 

• Delays leaf senescence 

• Can inhibit or promote (via ethylene stimulation) leaf and fruit abscission
