| Popis: | Siphonochilus aethiopicus (wild ginger) is one of only several thousand plant species used in traditional medicinal preparations in South Africa. The plant is threatened with extinction and is already extinct in the wild in the KwaZulu-Natal Province and is increasingly threatened in the Mpumalanga Province where small populations are reported to exist. The cone-shaped rhizomes and fleshy roots are extremely popular and are widely used in traditional medicines which include treatments for asthma, hysteria, colds, coughs and flu, as well as malaria, amongst others. Due to the unsustainable wild harvesting of this species, efficient in vitro micropropagation and acclimatization protocols were developed in efforts to conserve the species. Furthermore, using the aforementioned protocols, induced polyploid selections were developed in vitro and verified using flow cytometry. The effect of polyploidy on wild ginger with respect to selected horticultural characteristics was evaluated. |
