Tomato and cucumber fruits were exposed to various oxygen levels (5-100 %) at 20°C. In tomato, the higher the external oxygen level (O2 > 21%) showed higher respiration rate. In contrast, in cucumber fruit the respiration rate had a maximum at about 80% oxygen and was again lower at 100% oxygen. The internal O2 concentration in tomato and cucumber fruits increased with the increasing oxygen levels in the storage atmosphere. Moreover, the internal carbon dioxide concentrations in both tomato and cucumber fruits showed a similar pattern as the internal oxygen concentrations. The exception was the internal carbon dioxide concentration in cucumber fruit stored at 100% oxygen: here the internal carbon dioxide concentration was lower than that in 80% oxygen.
