The effects of incubation in the absence of a geomagnetic field were studied in embryos of White Leghorns in a series of experiments comprising about 500 treated specimens and approximately the same number of control specimens. No adverse effects were detected after the 2- or 9-days of incubation in a zero magnetic field produced by a compensation method in a special computer-controlled space. The prevalence of malformed and dead embryos, malformation spectra as well as stage distribution and mean weight of normal foetuses were similar in the control and the experimental groups. We conclude that magnetic field deprivation exerts no influence upon the morphological development of the chick embryo.


Key words: hypomagnetic field, embryogenesis, chick embryo.
