It works antagonistically to auxin to balance the growth with development in the shoot and root apex.Gibberellins promote internodal growth (bolting), especially in dwarf and rosette plants, like cabbage, when kept under short days.Ethylene is the gaseous hormone that stimulates growth and development of floral organs and promotes fruit ripening.
