What is Paclobutrazol?

Description

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

The Uses of Paclobutrazol

Paclobutrazol is a triazole fungicide used as an plant growth retardant in inhibiting gibberellin biosynthesis.
