Students will be able to
- outline the role of auxins in cell elongation and apical dominance, using IAA as an example,
- outline the role of gibberellins in germination and stem elongation,
- outline the role of ABA in stomatal closure,
- describe simple practical investigations into the effect of hormones on plant growth,
- analyze the experiments performed by Boysen-Jensen and Went to demonstrate the effect of auxins (IAA) on phototropism in shoots.
