Gibberellin-induced growth.
- Stem growth.
The Arabidopsis plant starts growth as a small rosette with short internodes.
Later in the growing season, a surge of gibberellin results in bolting:
elongating internodes and elevating the flower buds.
- Fruit growth.
Spraying a grape vine with gibberellin results in development of larger fruit,
as shown in the bunch on the right.
