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