摘要：

One-month-old plants of rape (Brassica napus cv. Drakkar) were subjected to water-deficit stress by withholding irrigation. Leaf lipid composition from control plants (well-hydrated) and water-stressed plants was analysed. Drought-stress induced a sharp decrease in galactolipid and phospholipid contents, whereas the content of neutral lipids increased. The fatty acid composition of leaf lipids was also affected under water-deficit stress. The percentage of linolenic acid (18:3) decreased mainly in monogalactosyldiacylglycerol and that of linoleic acid (18:2) in phospholipids.
