Article

Summary

The content of manganese of the egg ofOryzias latipes was determined by atomic absorption spectrophotometry and activation analysis. The amount of manganese in the unfertilized egg was 0.51 mμg and increased remarkably in one hour after fertilization. Although the increasing rate became gradually lower in further stages, the content of manganese amounted to 2.61 mμg in the embryo after gastrulation. Tracer-experiments showed that the egg accumulated manganese positively from the surrounding medium during the short time after fertilization.
