Summary
The activities of lipolytic acyl-hydrolases (LAH) and lipoxygenases (LOX) were compared in stored tubers of potato cultivars resistant (Acresta, Eba, Pentland Envoy) and susceptible (Kastor, Pana, Tasso) to post-wounding autolysis. In most cultivars, LAH activities had reached a maximum by the end of December but in cv. Kastor activity continued to increase throughout the storage period. LOX activities increased during most of the storage period except in cv. Tasso. The level of the fatty acid hydroperoxides, assumed from determinations of the malonaldehyde level, also increased during storage.
