Popis: Eighteen lines of Euvitis grapes in 1980, and 30 in 1981, were stored for 9 weeks at 0°C in 5.7-liter telescoping, corrugated cardboard shipping containers with polyethylene liners, with and without commercially available sulfur dioxide (SO2) generators (1 in 1980; 2 in 1981). Decay during storage without SO2 varied greatly among lines (2% to 81% in 1980 and 0% to 62% in 1981). The generator producing SO2 for the entire 9 weeks in 1981 eliminated decay of most grape lots. By comparison, the generators producing SO2 for only 2 weeks permitted 4 times as much decay. Two weeks of SO2, however, permitted only one-fifth as much decay as that associated with no SO2 during storage. Both generators reduced degradation of appearance and flavor of the grapes. The long-term generator was associated with more SO2 damage to the fruit than was the short-term generator. The lines varied widely in tolerance to SO2. SO2 damaged the fruit by entering openings in their surfaces caused by stem tears and cracks.
