[Influence of various physical factors on the developmental capacities of the ovum of Artemia salina].

Artemia salina dry eggs exhibit a great resistance to different physical factors: acceleration and vibration, low temperature, high vacuum and magnetic fields. Vibration test, alone or combined with acceleration test decreases the Artemia salina egg developmental capacity. Nevertheless, the differences are small and much lower than those observed in previous space experiments. The viability of Artemia eggs is not impaired by low temperature, high vacuum exposure and by high magnetic fields (15, 25 and 150 Koersted) or by earth magnetic field shielding.
