Plants hormones

Auxins:

  • growth/behavioral processes
    • plant life cycle and development
  • elongation during root and stem growth
  • required for fruit growth and delays  fruit senescence
  • important in phototropism
Abscisic Acid:
  • reacts to stress like temperature
  • abscission of fruits
  • inhibits plant growth to make sure it can survive stress
  • induces seeds to synthesize storage proteins
Ethylene:
  • stimulates release of dormancy
  • stimulates root and shoot growth
  • leaf and root abscission
  • stimulates fruit ripening and flower opening
