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.
The Uses of Paclobutrazol
Plant growth regulator.
What are the applications of Application
Paclobutrazol is a triazole antifungal
Definition
ChEBI: (R,R)-paclobutrazol is a 1-(4-chlorophenyl)-4,4-dimethyl-2-(1H-1,2,4-triazol-1-yl)pentan-3-ol in which both stereocentres have R configuration. It is an enantiomer of a (S,S)-paclobutrazol.
Agricultural Uses
Plant growth regulator: Used by arborists to maintain deciduous and broadleaf trees near buildings, reduce the growth of trees near power lines, and extend the longevity of trees on sites with limited natural resource.
