Review on Breeding Property of Ranalisma rostratum and Researches of Propagation Techniques

Reviews were made on biological and breeding properties of Ranalisma rostratum, an endangered plant species. Discussions were carried out on influences of interspecific competition, adaptive capacity to environment and the ability ofreproduction. Besides, development of artificial propagation was summarized. Recommendation was put forwardedsuch as establishing a bioengineering breeding base to meet the needsof basic and applied researches as well as protection.
