Summary
Blastula of trout (Salmo irideus) and pike (Esox lucius), deprived of their yolk, are cultivated in the Holtfreter solution. The differenciation of the germ of the trout stops; that of the pike germ is carried on almost normally. That difference might be due to the influence of nucleic acids contained in it.
