  • plant cells are totipotent (ie. each cell is capable of producing an entire plant)
  • auxin - rooting compound
  • cytokinins - shooting/leaves
  • gibberellins - elongation of cells
  • hormones / growth regulators
Hormone Function Location
Auxins (IAA)* stem elongation
root formation
apical dominanace
produced in shoot
apical meristem
Cytokinins cell division
differentiation
produced in roots
Gibberellins (GA)* stem & internode elongation
seed germination
produced in apical portion of root & shoot
Ethylene* abscission fruit ripening produced in leaves, stems & young fruits
Abscisic Acid supression of bud growth
stomatal opening
leaf senescence
mature leaves, fruits & root caps

* horticultural/agricultural applications
