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

This protocol allows students to investigate the effects of the hormone auxin (Indole Acetic Acid or IAA) as a plant growth regulator, giving 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.
Clearly explained lab practical presented as free-to-download PDFs.

The resource from SAPS is suitable for post-16 (age) students.
