Many discoveries of considerable importance to agriculture have been made accidentally while scientists have been working on other problems. The presence of a hormone, or growth-regulating substance, in plants has been known for many years, and in 1934 chemists were able to define the composition of this substance. With this information it was possible to prepare synthetically many related chemicals which were applied experimentally to plants, mainly for the purpose of stimulating growth, particularly with a view to promoting root development of cuttings.
