Abstract:

Storage experiments were conduced with fruit of two grape varieties, Muscat of Hambourg and Dabouki.

  1. The drop of Muscat of Hambourg is a "dry drop" while the Dabouki has no definite drop. Shed berries in this latter variety were due mostly to mechanical injury.
  2. The dry drop due to an abscission layer was found to be a "physiological drop".
    This drop could be:
    • Prevented by subjecting the fruit to cold store immediately after picking.
    • Reduced by spraying the fruit 4 days before picking with 10-20 ppm of NAA or PCPA if storage has to be postponed for more than 36 hours.
  3. Growth regulators as well as delayed cold storage had no effect on the drop of Dabouki berries during storage.
  4. A mechanism for the shedding in varieties with a physiological drop was suggested.
