The Effect of Growth Substances on the Stimulation of Root Growth in Cuttings of Coffea Arab

Abstract

Previous attempts to root cuttings of Coffea arabica at the Scott Agricultural Laboratories, although not completely negative, have given a poor percentage of success. The first trial carried out in which cuttings were treated with Hortomone" A"(1 part in 320 parts of water) for a period of eighteen hours prior to planting in the propagator gave results sufficiently conclusive to prove that a definite initiation of root growth had been obtained. These results led to the laying down of an experiment which is described below.
