how does it work?
- Abscisic Acid
cytokinins promote cell division (cytokinesis).It is wherever there is actively growing tissue.they help delay aging in plants by increasing the amount of new protein that is made.
Gibberellins are most important in stems, fruits and seeds. Gibberellins also work with auxin when fruit is developing.
Abscisic Acid also called ABA slows growth, and is the main player in seed dormancy. for example seeds do not grow until the condition is right, this is due to ABA keeping it dormant. ABA is also responsible for drought tolerance and preventing more water loss.
Ethylene helps fruits ripen by making them softer, through the breakdown of the cell walls. Ethylene is actually a gas and is distributed through the air, not through the plant.
