Abstract

The early divisions of sea urchin eggs was used as a model to study the effects of static and of 60 Hz sinusoidal magnetic fields. Two species were used (Sphaerechinus granularis and Paracentrotus lividus). Eggs were fertilized and exposed in two separate coils to the fields (up to 8 mT). Great care was taken to control the temperature of each sample. No difference was found in the time of the first division that could not be attributed to a temperature difference between samples. Comparison is made with other published data on various species.

摘要

海胆卵的早期分裂被用作模型来研究静态磁场和60赫兹正弦磁场的影响。使用了两个物种（颗粒海胆和紫球海胆）。卵受精后，置于两个单独的线圈中暴露于磁场（高达8毫特斯拉）。非常小心地控制每个样本的温度。未发现首次分裂时间存在无法归因于样本间温度差异的差异。与其他已发表的关于各种物种的数据进行了比较。
