Lipid composition and post-wounding degradation in potato slices from cultivars differing in susceptibility to autolysis

Summary The effect of cutting on lipid content and degradation were compared in tubers of potato cultivars resistant (Acresta, Aminca, Eba) or susceptible (Kastor, Pana, Tasso) to autolysis. Susceptible cultivars showed greater degradation of lipids and phospholipids as well as higher activity of lipid acyl-hydrolase. No significant differences were detected in the activity of lipoxygenase in the tissues of the studied cultivars.
