CONSERVATION AND VEGETATIVE PROPAGATION OF THE GENETIC RESOURCES OF SOME ENDANGERED MEDICINAL WOODY PLANTS OF NIGERIA |

| Abstract:
Vegetative propagation of 4 endangered medicinal plants: Zanthoxylum zanthoxyloides; Alstonia congensis; Rauvolfia vomitoria and Morinda lucida were carried out to mass propagation to aid in their conservation and plantation establishment in Nigeria. Single node leafy stem cuttings and root cuttings of the species were treated with different combinations of Naphthalene acetic acid (NAA); Indole-butyric acid (IBA) and Gibberelic acid (GA) at 4 levels (Oppm; 50ppm; 100ppm; 150ppm). The 4 species responded differently to hormone treatments. Cuttings from juvenile materials gave better rooting and survival percentages in all the species. All the four species tested are amendable to vegetative propagation. The implications of these findings for conservation and plantation establishment are further discussed. | |
