The contents of unsaturated fatty acids of thylakoid membrane lipids decreased and the saturated fatty acids increased with stressing time, resulting in a reduction in the index of unsaturation of fatty acid ( IUFA). 类囊体膜脂不饱和脂肪酸含量降低,饱和脂肪酸含量增加,导致膜脂不饱和指数(IUFA)逐渐降低;
The index of unsaturation fatty acid and palmitoleic acid/ linoleic acid in mitochondrial membrane lipids can be used as biochemical index of chilling-resistance in some plants. 线粒体膜脂脂肪酸不饱和指数和亚油酸/棕榈酸也可作为玉米芽期抗冷性指标。
