Moisture loss characteristics of grapes packed in different packaging liner films during cold storages (1.21 +/- 0.25 degrees C) were studied. The moisture loss rate from grapes packed in non-perforated liner films was significantly (P < 0.05) lower compared to the moisture loss rate from grapes packed in perforated liner films (120 x 2 mm and 36 x 4 mm perforated liner films). After 72 d of cold storage, the maximum moisture loss of grapes stems was significantly (P < 0.05) higher (range from 49.24 4.66% for non-perforated liner films to 88.55 +/- 0.61 for no packaging treatment) than moisture loss of grapes berries which was less than 10%. Transpiration coefficients of the different stem parts and grape berries stored in a no packaging treatment decreased significantly (P < 0.05) with storage period. The 36 x 4 mm perforated liner film resulted in a significant (P < 0.05) decrease of transpiration coefficients of the intermediate stem; large stem parts and berries. There were no significant differences between the transpiration coefficients of the bunch parts stored in the 120 x 2 mm and non-perforated liner films. The transpiration rates of stem parts were lowest in the non-perforated liner film compared to other packaging treatment, while the transpiration rates of grape berries showed no differences between the different packaging treatments (0.79 +/- 0.51 g kg(-1) d(-1), for the non-perforated liner film and 1.57 +/- 0.58; 1.59 +/- 0.75; 1.37 +/- 1.00 g kg(-1) d(-1), for the no packaging; 120 x 2 mm and 36 x 4 mm perforated liner films respectively).
