cv.

Halawani clusters were either sprayed (before two weeks of picking time) or dipped for 10 minutes with either CaCl2 or Ca(N03)2 solution at concentrations of (0 , 0.5 , 1%) .

Clusters were fumigated with SOz (1%) then stored in a perforated polyethylene bags (2 kg) in a cold storage on 0 + 1 C and 85-90% R.H.

Results indicated that dipping method significantly reduced berries weight loss to 1.03 and 2.80% at the end of the storage period (90 days) for both seasons , respectively.

This method also , significantly reduced berries drop to 1.89%, decay to 4.69%, but it increased the Ca content of berries to 0.075% at the end of the second season.

Increased Ca concentration to 1% significantly dec reased weight loss to 1.14 and 1.98% for both seasons, but it decreased berries drop to 1.75% and decay to 8.59% for the second season.
