Abstract
IN 1960 some interesting effects of fluorene-9-carboxylic acids on plants were observed at the biological research laboratories of E. Merck AG, Darmstadt, Germany. An intensified research programme on these compounds and on a great many derivatives was initiated by this company, which, during the following years, led to the discovery of a large-numbered group of compounds of substantial interest, some of which show an extremely strong action on the growth and development of plants1. This particular action has novel and somewhat unique features, and was reported first in 1964 by Schneider2.
