Influence of Nutrition on Growth and Configuration.—If ordinary green plants are grown in mineral nutrient solutions, the nature and concentration of the solution determine not only the rate of growth, but also the configuration and the internal anatomy of the plant. This relation of developmental phe- nomena to the conditions of nutrition is still more clearly evident in the case of lower plant forms that are nourished by organic substances. Mucor race- mosus, for example, produces thick hyphae with blunt branches, in sugar solu- ' BSssler, Fiiedrich, Ueber den Einfluss des Dekapitierens au£ die Richtung der Blatter an orthotropen Sprossen.
