Auxins – Plant Growth Regulators

The following are some of the responses that auxin is known to cause:

  • Stimulates cell elongation
  • Stimulates cell division in the cambium and, in combination with cytokinins in tissue culture
  • 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
  • Can induce fruit setting and growth in some plants
  • Involved in assimilate movement toward auxin possibly by an effect on phloem transport
  • Delays fruit ripening
  • Promotes flowering in Bromeliads
  • Stimulates growth of flower parts
  • Promotes (via ethylene production) femaleness in dioecious flowers
  • Stimulates the production of ethylene at high concentrations
