“…The macroscopic appearance of those plants which had been subjected as seeds to 24 hours' irradiation showed, in comparison with the controls, greater thickness of the sprouts and a constantly greater degree of turgescence. Phenomena such as have been called radiomorphoses (Caspari, 1926;Stein, 1927;Johnson, 1931) were not frequent in the present experiments; only slight changes in the distribution of the coloured constituents were noticed. Pale streaks and circular spots appeared on the leaves in Exps.…”

IV. SummaryStimulatory effects upon germination and growth were observed in a very wide range of dosages, upon exposing seeds and seedlings to the radiation from a radioactive mud of Hungarian origin. Emanation was not excluded, but interposed lead sheet practically abolished the significant differences. Stimulation was observed whether the seeds were placed directly in contact with, or at a little distance from, all but the largest amounts of mud. Treatment of seeds, before sowing, with the radiation from large amounts of mud for periods exceeding about 48 hours was harmful to germination and to growth; this harmful effect was more marked when the seeds were moistened.The degree and the kind of stimulation varied with the kind of seed and its history. Wheat seeds treated with vital stains showed responses to irradiation which appeared to depend upon the stain.
