Investigation of Wild and Cultivated Resources of Fallopia multiflora in Guangdong
Abstract:Objective:The research is aimed to investigate the wild and cultivated resources of Fallopia multiflora (Thunb.) Harald in Guangdong,and lay a foundation for the protection of the germplasm resources and production of F.multiflora.Methods:The distributions,deposits and utilizations of F.multiflora in Guangdong were analyzed based on the literature studies,interview survey and field investigation on the wild and cultivated resources of F.multiflora in Guangdong province.Results:The wild resources of F.multiflora are mainly distributed in the north and west parts of Guangdong,and too few to be collected for utilization.The cultivated resources of F.multiflora are distributed in Zhaoqing,Maoming,Yunfu and Shaoguan.The root tubers of F.multiflora cultivated for 2~3 years in Zhaoqing,with 1.7×106 kg of deposits,are used as medicine,while those cultivated for one year in Maoming and southern Yunfu (Xinxing and Luoding) ,with 3.5×106 kg of deposits,are used as health food or shampoo ingredients.The root tubers of F.multiflora,cultivated in Shaoguan and northern Yunfu (Yuncheng ang Yunan) will be collected after 2~3 years of cultivation,and the quality needs to be detected.The stems and leaves of F.multiflora,which can be used as medicines,have been discarded as waste in Guangdong.Conclusion:It’s severely urgent to improve the protection and utilization situation of F.multiflora in Guangdong.The governments,scientists,companies and farmers should cooperate with each other in promoting the healthy development of F.multiflora industry by wild resources protection,variety breeding,standardization of the whole production chain of crude drugs,new drugs research and development,brand promotion of F.multiflora.
