Applications of Abscisic Acid (CAS# 21293-29-8)
As a key plant hormone, abscisic acid plays a vital role in regulating physiological processes across various plant developmental stages. Its functions include promoting leaf abscission, inhibiting excessive growth, and inducing dormancy. Additionally, it facilitates stomatal closure, aids in seed embryo development, and improves plant resilience against environmental stressors such as drought, cold, and soil salinization. Due to these properties, abscisic acid is extensively utilized in agricultural practices and ecological vegetation restoration projects.
