Abstract
Excepting in the case of the timothy, the data presented here do not support the theory that fructose is superior to glucose as a tissue former. Fructose under the conditions of these experiments has a tendency to be toxic to the roots of pea, alfalfa, and Bryophyllum. In some cases this toxicity is temporary. When the two sugars are in the same solution there is no injurious effect to the pea. The pea, alfalfa, radish, and timothy can greatly increase their dry weights when grown in the dark on nutrient solutions containing these sugars. In one or two instances there was an increase of nearly ten times the weight of the seeds sown.
