The glyco- and phospholipid levels in green, green-yellow and yellow leaves of Impatients balsamina L., Daucus carota L. and Cucurbita pepo L. were determined on a leaf area basis. In Fagus silvatica L. leaves the kinetics of lipid breakdown during autumnal senescence was analysed. It was shown that yellow tissues still contain 40% to 50% of galactolipids and 50% to 60% of phospholipids present in green tissues. In the early stages of senescence of autumnal Fagus leaves we found a more rapid decline in the levels of the galactolipids and of the phospholipids phosphatidylglycerol and phosphatidylcholine, whereas in the later stages the breakdown of these lipids is slower than that of chlorophyll. The last yellow stage still contains 30% of the galactolipids and about 23% of the phospholipids present in fully greened leaves. Phosphatidylinositol shows a different behavior during senescence.
以叶面积为基础，测定了凤仙花、胡萝卜和西葫芦绿色、绿黄色及黄色叶片中的糖脂和磷脂水平。分析了欧洲山毛榉叶片秋季衰老过程中脂质分解的动力学。结果表明，黄色组织中仍含有绿色组织中40%至50%的半乳糖脂和50%至60%的磷脂。在秋季欧洲山毛榉叶片衰老的早期阶段，我们发现半乳糖脂以及磷脂酰甘油和磷脂酰胆碱的水平下降得更快，而在后期，这些脂质的分解比叶绿素的分解要慢。最后一个黄色阶段仍含有完全绿叶中30%的半乳糖脂和约23%的磷脂。磷脂酰肌醇在衰老过程中表现出不同的行为。
