A farmer sprayed an apple tree with gibberellin. Suggest two reasons why the farmer sprayed the apple tree with gibberellin.

Gibberellins are another group of plant hormones used in agriculture to control plant growth and development. For an apple farmer, they are useful for several reasons: - **Increase Fruit Size:** Gibberellins can stimulate cell division and cell elongation in the fruit, leading to larger apples, which can be more commercially valuable. This is a common use for gibberellins in growing grapes. - **Promote Flowering:** They can be used to induce flowering, sometimes causing plants to flower earlier or in different seasons than they would naturally. - **End Dormancy:** Gibberellins are involved in breaking seed dormancy and promoting germination, though this is less relevant for an established apple tree.
