The size and population density of large and small particles from freeze-fractured chloroplasts of three wild-type algae and of normal spinach were determined. Computer analyses of low-temperature absorption spectra of chloroplast preparations from these species were performed, and a possible correlation between the occurrence of seven chlorophyll complexes and the aforementioned properties of the intramembranous particles was studies. It was found that only single-sized particles occur in a species containing neither chlorophyll b nor chlorophyll a-685 complexes. The three remaining species carry particles of two sizes, termed large and small particles. However, from quantitative considerations it is concluded that the chlorophyll content of none of the various pigment complexes is related to the size and the population density of the studied particles. If such a relationship exists, it seems likely to be due to the carrier moiety of the chorophyll b-chlorophyll a-685 complex.
测定了三种野生型藻类和正常菠菜冷冻断裂叶绿体中大小颗粒的尺寸和种群密度。对这些物种叶绿体制剂的低温吸收光谱进行了计算机分析，并研究了七种叶绿素复合物的出现与上述膜内颗粒特性之间的可能相关性。发现仅在既不含叶绿素b也不含叶绿素a - 685复合物的物种中出现单一尺寸的颗粒。其余三个物种携带两种尺寸的颗粒，称为大颗粒和小颗粒。然而，从定量考虑得出的结论是，各种色素复合物的叶绿素含量均与所研究颗粒的尺寸和种群密度无关。如果存在这样的关系，似乎很可能是由于叶绿素b - 叶绿素a - 685复合物的载体部分。
