Abstract
Paclobutrazol (PB) soil drenches applied at 0, 10, 20, 30, 40, or 50 mg·liter -1 to potted Vitis vinifera L. `Pinot noir' vines inhibited extension growth of shoots on untopped vines and growth of lateral shoots on topped vines. Internode length, leaf area, and cane maturity were also reduced by the PB soil drenches. Foliar application of gibberellic acid (GA 3 ) appeared to remove the effects of PB on the length of some internodes. Chemical name used: β[(4-chlorophenyl)methyl]-α-(1,1-dimethylethyl)-1 H -1,2,4-triazole-1-ethanol (paclobutrazol).
