Vegetative propagation of Ricinodendron heudelotii, a West African fruit tree

Leafy stem cuttings of Ricinodendron heudelotii (Baill) Pierre ex Pax, a West African fruit tree, were taken from seedlings or coppice shoots and inserted in a low-technology non-mist propagation system in Cameroon. Three separate experiments were tested: (i) six propagation media, namely sawdust (S...
