On the magnesium content of the egg of the Medaka,Oryzias latipes, and its changes accompanying fertilization

Article

Summary

The content of total and bound magnesium of the egg of the Medaka,Oryzias latipes was determined by atomic absorption spectrophotometry. The amount of total magnesium remained unchanged before and after fertilization. When the egg was fertilized, the concentration of bound magnesium decreased in ten minutes after fertilization and then amounted to upwards of the original value by the blastula. The role of magnesium in the fertilization process was discussed with the presence of the experimental results.
