Mode of Action
Paclobutrazol is an effective plant growth regulator that works by inhibiting the biosynthesis of gibberellins, which are plant hormones responsible for cell elongation and stem growth. Paclobutrazol is absorbed by plant tissues, primarily through the roots, and transported to the actively growing parts of the plant, such as the shoots, buds, and meristematic tissues. Once inside the plant, Paclobutrazol targets an enzyme known as ent-kaurene oxidase, which is involved in the biosynthesis of gibberellins. By inhibiting this enzyme, Paclobutrazol effectively reduces the production of gibberellins in the plant. Gibberellins are responsible for promoting cell elongation and stem growth. By inhibiting their biosynthesis, Paclobutrazol reduces the elongation of internodes (the spaces between leaves or branches), resulting in shorter and more compact plant growth. This controlled growth helps prevent plants from becoming excessively tall and reduces the risk of lodging (falling or bending due to weak stems) and breakage.
