The fatty acid composition of callus cultures of salad vegetables differing in chilling sensitivity was analysed. A growth temperature of 12°C (8 h)/4°C (16 h) increases the content of unsaturated linolenic acid and therefore the degree of lipid desaturation in Cichorium endivia L. var. "Prima Rossa". This increased desaturation can be demonstrated in the total lipid extract, in triglycerides, in phospholipids and in mitochondrial lipids. The low temperature induced changes are reversible. Callus tissue returned to 25 °C after a period of low temperature treatment shows a fatty acid composition similar to the original. The chilling-resistant Lactuca sativa L. var. "Arctic King" has a high content of polyunsaturated fatty acids even at 25°C which is unchanged at low growth temperature.
