The Biosafety Assessment of Introduced Pennisetumsp.in Fujian Province,China

Based on analyzing the introduced ways, biological characteristics, and potential hazards of Pennisetum sp, as well as the ecological environment and management status, an index system for risk assessment of Pennisetum sp.was established, consisting of 3different layers, ie.objective, criteria, and index layers, which include 20 index parameters, by following the principle of essentiality, systematicness, practicality and portability, and used to evaluate the risk rank of Pennisetum sp.in Fujian Province.The results showed that there was no risk to plant Pennisetumsp.in Fujian Province, which can be introduced or need not to take any preventive measures.Our work provides a theoretical basis for the safety of introduction, and large-scale cultivation and production of Pennisetum sp.in Fujian Province, beside that it will be of great importance in improving the economic benefit and protecting the biodiversity in our country.
