Question

Which hormone controls apical dominance? List any two functions of the hormones.

Answer 1

Auxin:

1. Auxin is a plant hormone that promotes the growth of plant shoots.
2. The phenomenon where the central stem is dominant and the lateral stems and bugs suppress is called apical dominance.
3. Apical dominance arises due to auxin production at the tip of the plant shoot.
4. Auxin is also used to promote parthenocarpy to produce seedless fruits.
5. This plant hormone also induces root formation in stem cuttings and is extensively used in horticulture.
