In experiments during 5 years, commercially ripe fruits of 4 apricot cultivars were harvested and placed in anaerobic conditions for up to 14 days. During anaerobiosis pH increased and titratable acidity decreased, while sugars, especially sucrose, and malate decreased. Ethanol production increased, with a greater increase at 25 deg C than at 20 deg . Activities of various metabolic enzymes showed that activity, especially that of alcohol dehydrogenase, was lower in the early maturing cultivars Tirynthe and Rouge de Rousillon than in the later maturing cultivars Polonais and Bergeron; these later maturing cultivars also produced the highest levels of ethanol. Anaerobiosis had little effect on the volatiles of the late maturing cultivars but improved those in the early maturing cultivars by decreasing the levels of C6 compounds and increasing the levels of other compounds.
