 Use of Abscisic acid


Abscisic acid ((S)​-​(+)​-​Abscisic acid) is a plant hormone which is as a growth inhibitor. Abscisic acid has been shown to regulate many aspects of plant growth and development including embryo maturation, seed dormancy, germination, cell division and elongation, floral induction, and responses to environmental stresses such as drought, salinity, cold, pathogen attack and UV radiation[1].
