Phototropism of Phycomyces Sporangiophores

Article metrics

Abstract

THE primary purpose of my previous communication1 was to show that the reversal of phototropism at about 300 mµ reported by Curry and Gruen2 is explicable in optical terms, and that it was not necessary to postulate a novel photochemical reaction occurring in the far ultra-violet. I also felt that it was useful to point out that Curry and Graen's results on the relative effectiveness of different wave-lengths when plotted as an action spectrum give a curve similar to the absorption spectrum of riboflavin. I agree with Banbury as to the dangers inherent in this procedure, and realize that observations on the effectiveness of a range of wave-lengths in promoting the light-growth response would, if available, provide a better guide as to the nature of the photoreceptor substance.
