The spectral characteristics of the leaves and chloroplasts from Xiuyou

本文研究了秀优杂交稻和富士光两个水稻品种的光谱特性。实验结果表明,这两个不同产量水平的水稻品种,其光谱特性具有明显差别。在含等量叶绿素的情况下,高产的秀优杂交稻比低产的富士光对光的吸收能力更大,前者的叶片具有更高的潜在光合作用量子转化效率;叶绿体的PSⅡ潜在活性和PSⅡ原初光能转化效率也高。与富士光相比,Mg~(2+)不仅能较大幅度地提高秀优杂交稻叶绿体上述两个光合作用参数,而且对它两个光系统之间的激发能分配也有较大的调节能力。

In addition, the ratio of relative fluorescence intensities of PSⅡ to PSⅠin the presence of Mg~(2+) and the ratio of relative fluorescence of intensities of PSⅠto PSⅡ in the case of thylakoid membrane protein phosphorylation were also enhanced by pretreatment with 2,3-COPA,respectively.These results illustrated that the capacity of excitation energy distribution regulated by Mg~(2+) or the phosphorylation of thylakoid membrane between PSⅡ and PSⅠwas strengthened by 2, 3-COPA. The results further showed that effects of 2,3-COPA on photosynthetic processes may be many-sided and 2, 3-COPA will have some prospects for practical application to rice production.
