Freeze-damaged 'Valencia' oranges [Citrus sinensis (L.) Osbeck] were tightly covered with polyethylene bags while still on the tree, and their dehydration rates were compared to those of nonbagged fruit. The bags significantly reduced water loss from fruit over 11 wk after the freeze. After fruit were harvested and removed from the bags, previously bagged fruit had higher water loss rates than nonbagged fruit. A significant amount of water in the fruit was lost through the peel after freeze damage occurred. The dryness cut method did not quantitatively determine dehydration of freeze-damaged oranges.
