1) Flowering: Hormones play a crucial role in regulating the process of flowering in plants. For example, a hormone called gibberellin promotes flowering by stimulating stem elongation and causing the opening of flower buds. On the other hand, another hormone called abscisic acid inhibits flowering by preventing the growth of flower buds.
2) Seed germination: Hormones are involved in regulating the germination of seeds in plants. Abscisic acid is one such hormone that inhibits seed germination, keeping the seeds in a dormant state until favorable conditions for germination are present. On the contrary, gibberellins promote germination by stimulating the breakdown of seed dormancy and promoting cell division.
3) Root growth and development: Hormones also regulate root growth and development in plants. Auxins, one of the major plant hormones, control root elongation and branching. They promote the growth of roots, especially in response to gravity, and influence root initiation during vegetative propagation. Additionally, cytokinins, another group of plant hormones, stimulate the growth and development of lateral roots, which help plants absorb water and nutrients efficiently.
