Abstract
THE action of radium compounds on plants is discussed by Prof. H. Molisch in a short article published in the Sitzungsberichte der kaiserlichen Akademie der Wissen-schaften, Vienna (vol. cxx., part v.). Experiments showed that sufficient light is emitted by strong preparations to produce heliotropic curvature in the case of very susceptible plants such as the oat and the common vetch. With regard to the action of the α, β, and γ rays, it was found that longitudinal growth is diminished and that the periods of spontaneous nutation are shortened, but they induce no form of tropism.
