Tomato fruits (cv. Sonatine) were stored in 6% CO2, 6% O2 and 88% N2 for 14 weeks at 12 degrees C. The specific activities of citrate synthase and malate dehydrogenase fell during the first 2 weeks of storage, when changes in organic acid concentration also occurred. During this period, lycopene, polygalacturonase and ethylene were undetectable.
