Abstract
Gibberellin sprays applied during the bloom period to Thompson Seedless vines used for table grapes resulted in a decrease in berry set, an increase in berry size, and higher soluble solids. The berries were also elongated by the gibberellin treatments.
Gibberellin concentrations of 10 and 20 ppm produced loose, attractive clusters. Concentrations of 25, 50, and 100 ppm induced the development of undesirable shot berries.
There were no significant differences in berry set between the 10- and 20-ppm treatments or between spraying at 10 and 70% bloom.
The berry thinning effect from the gibberellin was relatively uniform throughout the cluster. This is important in market acceptance of table grapes.
