Low temperature fluorescence spectra and second derivatives of chlorophyll absorption spectra in leaves, chloroplasts of mesophyll and parenchyme bundle sheath cells (BSC) were studied. It has been shown that in ontogenesis of BSC chloroplasts of Zea mays leaves along with a decrease of the activity of the PS-2 and a reduction of granal regions the fluorescence maximum of chlorophyll decreases at 695 nm. The change of this fluorescence band is concerned with the disturbance of the form of chlorophyll "a" absorbing at 684 nm and performing the function of an antenna of the pigment-protein complex of PS-2. Similarities in the distribution of chlorophyll forms between three pigment-protein complexes of chloroplast membranes in green algae and higher plants are discussed.
研究了叶片、叶肉叶绿体和薄壁维管束鞘细胞（BSC）中叶绿素吸收光谱的低温荧光光谱和二阶导数。结果表明，在玉米叶片BSC叶绿体的个体发育过程中，随着PS-2活性的降低和基粒区域的减少，叶绿素的荧光最大值在695nm处降低。该荧光带的变化与吸收684nm光并执行PS-2色素-蛋白复合体天线功能的叶绿素“a”形式的紊乱有关。讨论了绿藻和高等植物叶绿体膜的三种色素-蛋白复合体之间叶绿素形式分布的相似性。
