Recent advances in vegetative propagation techniques of Theobroma cacao L. under Malaysian conditions

Throughout the world, the cocoa plant had been vegetatively propagated mainly by means of rooted cuttings, bud-grafting and, to a limited extent, by marcots and grafts. Rooted cuttings and buddings were associated with major drawbacks. The production of rooted cuttings involved investment in basic f...
