Investigating the hormone auxin (IAA), a plant growth regulator

This protocol allows students to investigate the effects of the hormone auxin (Indole Acetic Acid or IAA) as a plant growth regulator. The investigations give opportunities to look at auxiliary bud development, root development, and leaf abscission in Coleus. The method is suitable for independent investigations by students. Two potential investigations are suggested.
