5.3 Application of Phytohormones in Agriculture
 
Phytohormone Application in agriculture
Auxin
  • Application of auxin to flowers without fertilisation stimulates formation of seedless fruits,a phenomenon known as parthenocarpy
  • Application of auxin as rooting powder to stimulate growth of adventitious roots
  • Synthetic auxin. 2,4-D is used as weed killer to kill eudicot weeds
  • Natural and synthetic auxin is also used to delay fruit drops
Gibberellin
  • Stimulates stem elongation of dwarf plants
  • Speeds up seed germination
  • Stimulates increase in fruit size of grapes
Cytokinin
  • Stimulates production of root and shoot in tissue culture in the presence of auxin
  • Stimulates growth of root and stem
  • Prolong storage period of green leafy vegetables 
Abscisic acid
  • Prevent seed germination in an appropriate season
Ethylene
  • Stimulates fruit ripening after import for marketing
  • Speeds up maturation in pineapple and watermelons
