• The nature of macromolecular "auxin protector substances" causing lag periods rather than inhibition in the rate of IAA oxidation was reinvestigated. Three different peaks were separated by Sephadex gel filtration; each was then examined by means of enzymatic (IAA oxidase, peroxidase) and electrophoretic techniques and correlated with the activities of both enzymes and with zymogram patters. The auxin protector activity of the high molecular weight fractions increased after high temperature treatment. On the basis of experiments involving dialysis and chromatography before and after heating, auxin protectors appear to be complexes of macromolecules with small molecules.
