Application
Paclobutrazol: An Inhibitor of Gibberellin Biosynthesis
Paclobutrazol, a triazole derivative, is an inhibitor of gibberellin biosynthesis. Gibberellins, including gibberellin A3 [G0029], are plant hormones that regulate growth and influence various developmental processes. Therefore, paclobutrazol is applied to suppress the growth of the shoot. (The product is for research purpose only.)
