What is Abscisic Acid and its Uses
Abscisic acid is a plant hormone or phytohormone that regulates numerous aspects of plant growth, development, and stress response. Abscisic acid-deficient mutants in various plant species exhibit reduced seed dormancy and wilted phenotypes, highlighting that these important abscisic acid functions are conserved in the plant kingdom. Its chemical Formula is C15H20O4.
Chemical Structure of Abscisic Acid:
Functions of Abscisic Acid:
- Inhibits the stomatal opening.
- Act as a signal to reduce shoot growth (under water stress conditions).
- Promote leaf senescence.
- Inhibits seed germination and metabolism of the plant.
- For dropping fruits from trees, used as a spraying agent.
Uses of Abscisic Acid
Abscisic Acid has an essential role in multiple physiological processes of plants, such as stomatal closure, cuticular wax accumulation, leaf senescence, bud dormancy, seed germination, osmotic regulation, and growth inhibition among many others.
