| 摘 要： | 实验测定了雨生红球藻不同生长阶段的色素组成,吸收光谱,荧光光谱,并对其进行了分析。结果表明,用490nm波长激发时,雨生红球藻在绿色细胞阶段存在710nm和730nm附近的长波长荧光发射峰,而在红色细胞阶段仅存在730nm的长波长荧光发射峰,预示着雨生红球藻不同生长阶段在PSⅠ结构,组成,及其色素蛋白的排布等方面有很大差异。 |

| Abstract: | The pigment composition, the absorption and fluorescence spectra of Haematococcus in different growth phases was measured in this study. The result showed that the wavelength is excitated at 490nm, two fluorescence emission at 710nm and 730nm in the stage of green cells were observed, while in the stage of red cells, a fluorescence emission only at 730nm was observed. The results suggested there are significant differences in PSI structure, constitute and distribution of chromoprotein in different stage of Haematococcus. |
| Keywords: | Haematococcus pluvialis spectrum characteristic green cell red sporule |
