Formation of Aggregations of Glaucoma pyriformis Kahl by Means of Phenanthraquinone and Other Substances

Abstract

PHENANTHRAQUINONE has been shown by Powell1 to be an inhibitor of the growth of Twort carcinoma and by Jones2 as a potent inhibitor of root growth. In the course of similar work on the growth of cultures of Glaucoma pyriformis, it was observed that if a few drops of phenanthraquinone solution were added to a culture in a watch-glass, the individuals collected into aggregations which are clearly discernible, against a dark background, as circumscribed, whitish areas.
