Axenic Culture of Utricularia

Abstract

Pringsheim, Ernest G., and Olga Pringsheim. (Pflanzenphysiologisches Inst., Göttingen, Bundesrepublik Deutschland.) Axenic culture of Utricularia. Amer. Jour. Bot. 49(8): 898–901. Illus. 1962.—Utricularia exoleta, a small tropical floating carnivorous plant, was freed of other organisms by hypochlorite treatment. An inorganic nutrient solution was composed which produced good vegetative growth but flowering only if organic compounds, as contained in beef-extract, were added aseptically.
