What do these plant hormones do?

What are some plant hormones that are easily available?

• Can you please mention some plant hormones (and their purpose) that are easy to get OTC in places such as flower stores or a generic shop? Thank you :)

• Answer:

  auxin (Indolacetic acid or IAA) : Stimulates elongation of stems and causes tropic responses to light and gravity, stimulates root development on tissue cuttings. Should be available from garden centers gibberellins: stimulates enlargement of fruits. Should be available from garden centers or catalogs ethylene gas: stimulates flower production and ripening of fruits (comes from ripe fruits such as a ripe banana or apples. Enclose the target plant in a plastic bag with the ripe fruit)
