What is gibberellic acid?

GA3 is the abbreviation of Gibberellic Acid. It is a plant auxin, one of the naturally occurring hormones in plants, and plays an important role in the growth and development of plants. Gibberellic acid can affect plant elongation and growth, promote seed germination, control plant flowering and fruit growth and other processes. In agriculture and horticulture, gibberellic acid is often used as a plant growth regulator to help plants achieve better growth performance at specific growth stages.
