Phytohormones in Plants
- Phytohormones are plant hormones that regulate their growth, development, reproductive processes, longevity, and even death
- There are many chemicals which act as phyohormones in plants, some examples include:
- Auxins which result in cell elongation
- Abscisic acid which suppresses the growth of plants
- Cytokinins which increase the rate of cell division
- Ethylene which promotes fruit ripening
- Gibberellin which control cell elongation, seed germination, flowering and dormancy
- Brassinosteroids which regulate growth, development, and responses to stresses
- Plant hormones are sometimes referred to as plant growth regulators
