Abstract
THE Avena method of estimating auxin in plants requires such technical perfection and specialized apparatus that it is rendered useless to workers who have no access to elaborate equipment. The method described below has been worked out under ordinary greenhouse conditions and, while it is fully recognized that it cannot yield such exact quantitative results as the Avena test method, it has proved of use in comparative work and with more fully controlled conditions suggests possibilities for finer quantitative estimations.
