Occurrence of Indole-3-Acetic Acid in Laminæ of Hevea brasiliensis

Abstract

IT became necessary during the examination of the effect of various mineral nutrients on rubber production in Hevea to investigate the occurrence of indole-3-acetic acid in the laminæ. Although it is assumed that this auxin is present in most plants, this assumption has never been verified for Hevea. Chapman1 showed by means of the Avena curvature test that in some instances the yield of rubber was related to the concentration of ‘hormones’ in the latex serum but did not indicate specifically that indole-3-acetic acid was present.
