| 摘 要： | 干旱条件下山楂线粒体膜脂中棕榈酸和油酸含量减少，亚麻酸含量增多，从总脂肪酸看，饱和脂肪酸含量减少，不饱和脂肪酸含量增多。脂肪酸不饱和系数增大。叶绿体膜脂肪酸中，棕榈酸在干旱时的变化规律与线粒体膜棕榈酸的变化相同，随干旱而减少，油酸含量在轻度干旱时减少，严重干旱时增多，亚麻酸含量变化不大，干旱时叶绿体膜脂肪酸不饱和系数增大。

| Abstract: | The composition of fatty acids in Mitochondria and chloroplast membranesdid not change but the contents of fatty acids changed when hawthorns were subjectedto drought,the contents of palmitic acid and stearic acid decreased,but linolenic acidincreased in mitochondria membrane lipid on drought.The content of palmitic aciddecreased in chloroplast membrane,oleic acid increased when hawthorus were on severedrought,linolenic acid changed a little.The total satured fatty acid decreased,unsatured fatty acid increased both in mitochondria membrane lipid and chloroplastmembrane lipid, the index of unsatured fatty acid(IUFA)got higher when hawthornswere on drought. |
