Abscisic Acid CAS #21293-29-8
S-Abscisic Acid (ABA) is a plant hormone, also known as Abscisic acid, named after it was originally thought to promote plant leaf abscission. It plays a role in multiple developmental stages of plants. , in addition to promoting leaf shedding, there are other effects, such as inhibiting growth, promoting dormancy, promoting the formation of potato tubers and plant stress resistance.
In fact, abscisic acid is only found in a small number of plants in promoting leaf abscission. abscisic acid can also be synthesized in some phytopathogenic fungi, but it is different from the synthesis pathway in plants. At present, the production of high-purity abscisic acid has been successfully produced by fermentation of Botrytis cinerea on a large scale. Products, and are widely used in agricultural production, disaster prevention and mitigation, ecological vegetation construction, afforestation, urban landscaping and other fields.
