Abstract
- Of three systems, bulb tissue, plant leaf tissue and intact green algal (Chlorella vulgaris) cells, only the former shows an increase in rate of formation of unsaturated fatty acids with decrease in temperature. 2. In bulb tissue the oxygen concentration is rate-limiting for synthesis of unsaturated fatty acids at temperatures down to 10 degrees . 3. At elevated oxygen concentrations the formation of unsaturated fatty acids in bulb tissue increases with temperature. 4. The failure of photosynthetic tissues to respond to either lower temperatures or increased oxygen concentrations in the presence of light is attributed to photosynthetic production of excess of oxygen. This is supported by the fact that in the dark a potentiating oxygen effect on the formation of unsaturated fatty acids can be demonstrated. 5. The HCO(3) (-) ion concentration has a small effect on the formation of unsaturated fatty acids. 6. Elevated content of unsaturated acids at lower temperatures in plants is attributed to increases in oxygen concentration in solution.
摘要
- 在球茎组织、植物叶片组织和完整的绿藻（普通小球藻）细胞这三种体系中，只有前者显示出随着温度降低不饱和脂肪酸形成速率增加。2. 在球茎组织中，温度低至10摄氏度时，氧气浓度是不饱和脂肪酸合成的限速因素。3. 在氧气浓度升高时，球茎组织中不饱和脂肪酸的形成随温度增加。4. 在有光照的情况下，光合组织对较低温度或增加的氧气浓度均无反应，这归因于光合作用产生过量氧气。这一观点得到如下事实的支持：在黑暗中，可以证明氧气对不饱和脂肪酸的形成有增强作用。5. HCO(3) (-)离子浓度对不饱和脂肪酸的形成影响较小。6. 植物在较低温度下不饱和酸含量升高归因于溶液中氧气浓度的增加。
