What Does IAA Stand For?
IAA stands for Indole 3 Acetic Acid
Indole 3 Acetic Acid (IAA) is a naturally occurring plant hormone belonging to the class of auxins. It plays a crucial role in coordinating various growth and developmental processes in plants, such as cell elongation, root initiation, and fruit development. IAA is synthesized primarily in the shoot apical meristem, and its concentration can influence plant responses to environmental stimuli, thereby contributing to processes like phototropism and gravitropism.
