Hormonal Growth Control

Plant Growth:

•Auxins - help vegetative propagation - stimulates root growth

•Gibberlins - shoot growth - used on cereals to produce shorter stems
 - stimulate seed germnination
 - root growth
 - increase fruit size

•Ethane or Ethylene - stimulates the ripening of fruit


Animal growth:

•BST - increases milk yield in dairy cattle
 - banned in many countries due to risks to human health

•Anabolic Steroid Hormones
 - based on steroid sex hormones
 - increases growth rate and gross growth efficiency
 - if residues of the steroid remain in meat eaten by humans it could affect human growth
