Gibberellins in plant growth 
  1. Gibberellins were first isolated from the culture of a fungus Gibberella fujikuori.
  2. Gibberellins has a significant effect on stem elongation.
  3. It also increases the leaf blade area. This is due to stimulation of cell division and cell elongation in both leaves and stem.
  4. When applied as a spray on plants, it increases the size of the fruits like grapes.
  5. Dwarf and rosette plants like cabbage and dwarf pea plants grow taller after treatment with gibberellins.
  6. Gibberellins along with auxins promote cell elongation and leaf expansion.
  7. These substances are also known to induce enzymes like amylase, protease, lipase etc., at the on set of seed germination and break the seed dormancy.
  8. These substances are used for fruit setting and also for growing seedless fruits.
  9. Parthenocarpy (seedless fruits) is induced in fruits like apple and pear with spray of gibberellins.
  10. In brewing industry, gibberellin is used to stimulate amylase activity in barley seeds. This is known to enhance malting of barley grains.
