Abstract

THIMANN1, using the standard Avena technique, showed that a growth-substance is produced in considerable amount in root nodules. He further-more claimed that the growth-substance produced is not derived from the meristematic tip of the nodule, but comes directly from the bacterial tissue. He found that the symptoms induced by 3-indole-acetic acid upon roots closely resembled those produced, in Molliard's work, by the action of sterile filtrate of nodule bacteria upon pea roots, and he consequently believed that the bacteria cultivated in laboratory media produce growth-substance in considerable amount.
