Regeneration of Blepharisma undulans variety japonicus from which the hypostome has been removed is retarded by dosages of 3000 to 4600 ergs/mm.(2) at wavelength 2654A most strongly when the fragment is exposed soon after cutting. Dosages greater than 4600 ergs/mm.(2) prevent regeneration. Regeneration is also retarded strongly when the Blepharisma are cut soon after irradiation. Starvation ret...
