ABSTRACT
Natural obligation for cross-pollination coupled with low seed production is unsuitable for propagation of Ceropegia species through seeds. Though the tuber is perennial, in one growth season it produces only a single plant. The natural populations are rapidly decreasing due to consumption of tubers by humans and animals. Vegetative propagation by root tubers is tedious and is too low to meet the commercial needs (Beena and Martin, 2003). Therefore, there is an urgent need for conservation measures like in vitro propagation of these species.
