药用葛优良种质资源筛选研究

Study on the Selection of Germplasm Resource Medicinal Pueraria lobata

采用野外搜集和引种方式搜集了葛种质资源36份,进行了种植试验和生物学性状调查、产量测定及药用成分(葛根素、总黄酮含量)和淀粉含量测定;并对2 a生葛资源从药用价值、经济效益两方面进行了评价。结果表明:3号横峰药葛和35号周至葛根2个品种(资源)在产量与葛根素及总黄酮含量方面都较高,其产量均在4 000 kg/667m2以上,葛根素含量都达2.5%以上,总黄酮含量也都在5.5%以上,而淀粉含量虽然不太高但也达10%以上,基本达到了野生药用野葛的葛根素含量水平,是值得进一步选育研究、规范其栽培技术和大力推广利用的2个优良药用葛根品种。

By field collection and introduction used to collect the 36 germplasm resources of Pueraria lobata,through planting test and biological properties investigation,the yield,pharmaceutical ingredients（puerarin,total flavonoid content） and starch content were mensurated,to medicinal resources Pueraria lobata of 2 years old from the medicinal value and economic efficiency was evaluated.The results showed that the yield and puerarin,total flavonoid content of Hengfeng No.3 medicinal Pueraria lobata and Zhouzhi No.35 Pueraria lobata were higher,its yield were over 4 000 kg/667m2,puerarin content were over 2.5%,the total flavonoids were all above 5.5%,starch content more than 10%,reaches the wild medicinal content of puerarin in Pueraria lobata level,is worthy of further breeding research,standardize cultivation techniques and promotes the use of two excellent varieties of medicinal Pueraria lobata.
