Application of paper chromatography to the separation and identification of auxins and growth-inhibitors.

Abstract

ADVANCES in auxin physiology within recent years have been limited by continued uncertainty as to the identity of the auxins present in various plant tissues, and by the absence of reliable methods of separating the growth-promoting and the growth-inhibiting substances present in plant extracts. The technique of paper chromatography, used in conjunction with biological tests, would seem to offer a ready solution to both these problems.
