The influence of gibberellic acid (GA) and Gibrel on the parthenocarpic development of cranberries ( Vaccinium macrocarpon cv. Early Black) was investigated. Application of GA or Gibrel at 25 % bloom, 50 % bloom, 100 % bloom and after bloom resulted in a much higher than normal percentage fruit set and large increases in yield. However, treatment of cranberry vines with these compounds also resulted in an abundance of small, commercially undesirable berries. In addition, application of GA caused abnormal elongation of the vines and inthibited terminal bud development. Gibrel caused only slight vine elongation and did not retard terminal bud development. The possible use of Gibrel in the commercial production of cranberries is discussed.
