Abstract
ON November 6, 1937, by invitation of the Director, a meeting to discuss the use of chemicals for stimulating the formation of roots on cuttings was held at the Royal Botanic Gardens, Kew. It is well known to botanists that, following the investigations on the Continent which led to the discovery, isolation and chemical identification of hormone-like substances controlling the growth of seedlings, these were found also to be capable of inducing the formation of adventitious roots. Since then, use has been made of β-indole-acetic acid and other synthetically produced substances in the hope that their application in aqueous solutions either directly in jars or by watering the compost would induce the formation of roots on cuttings. It would be of great value to horticulturists if cuttings of plants which do not 'strike' easily could be stimulated to do so in this way, or if the rooting of moderately easy subjects which are cultivated on a very large scale could be accelerated.
