摘要

Gassing during 14 days of Aleurites plants with 0.3 ppm SO2 leads to quantitative modifications of the lipid composition of leaves, The ratio of phospholipids to glycolipids is shifted from 1:3 in control plants to 1:1.8 in SO2-plants. Glycolipids decrease from 62% of total lipids in control plants to 50% in SO2-plants. On the other hand phospholipids increase from 20% in control plants to 28% of total lipids in SO2-plants. This implies that not only the thylakoid membrane but also the mitochondrial membranes and cell membranes of tonoplasts and of the plasmalemma suffer modifications under the influence of SO2. With respect to the fatty acid composition, despite the drastic change in the lipid composition no alteration in comparison to control plants is seen. Chlorophylls increase in SO2-plants by 24%. Also the content of beta-carotene, and of the xanthophylls lutein, violaxanthin and neoxanthin is increased. Only zeaxanthin exhibits a decrease. From the changes in the chlorophyll and carotenoid content it can be concluded that in SO2-plants the light-harvesting-complex (LHCP) is stronger developed. [References: 11]
