摘 要 ：用SDS — 聚丙烯酰胺凝胶电泳的方法，对比分析了老、嫩黄瓜叶片叶绿素蛋白质复合物之间的差异，发现嫩黄瓜叶片中缺少1条属光系统I的CPIb带。从低温荧光发射光谱观察到，嫩黄瓜的光系统I相对高于光系统Ⅱ，而老黄瓜则相反。指出在叶绿体发育过程中首先形成光系统I，以后是光系统Ⅱ。我们还注意到，叶片中的F685/F735比值与叶绿素蛋白质复合物中的单体／寡聚体比值之间呈正相关关系。

Abstract:The differences between the Chl-protein complexes from the old and the young leaves of cucumber were analysed comparatively by using SDS-PAGE method. The experimental results showed that there was no CPIb band-a band which belongs to PSI-in the young leaves. The 77K fluorescence emission spectra indicated that, in the young leaves, the PSI component was comparatively higher than that of the PSII, and just inverse with the old leaves. This implicated that, in the development of chloroplast, PSI forms primarily and then PSII appears. It is interesting to notice that there is a direct proportion between the F685/F735 ratio and the monomeric form /oligomeric form ratio of Chl-protein complexes.
