In this article we will discuss about:- 1. History of Abscisic Acid 2. Functions of Abscisic Acid 3. Uses. History of Abscisic Acid: It is also called stress hormone because the production of hormone is stimulated by drought, water logging and other adverse environmental conditions. Abscisic acid is known as dormin as it induces dormancy in buds, underground stems and [...]
In this article we will discuss about Indole-3-Acetic Acid (IAA) and Auxin in Plants. Natural and Synthetic Auxin: The main auxin in plants is indole-3-acetic acid (IAA Fig. 20-2). Additionally, several other naturraly occurring indole derivatives are reported to express auxin activity, including indole-3- ethanol, indole-3-acetaldehyde, and indole-3-acetonitrile. It may be noted that all these compounds are precursors of IAA [...]
