Paclobutrazol

Paclobutrazol ((R, R) -paclobutrazol) is a triazole-containing plant growth retardant that is known to inhibit the biosynthesis of gibberellins.1,2It also has antifungal activities.3PBZ, which is transported acropetally in plants, can also suppress the synthesis of abscisic acid and induce chilling tolerance in plants.1,4,5PBZ is typically used to support research on the role of gibberellins in plant biology.
