Chungbuk native Polygnatum stenophyllum Max. for used in this experiment were regional groups that collected at Cheongju and Jecheon, and then classified by seed tuber weights as 15, 30, 45, 60g. Shoot emergency time was faster about $4\sim7$days in Chengju regional group than that of Jecheon. In different seed tuber weights, shoot emergency time was the faster, seed tuber weight was the heavier. All of growth factors such as plant height, stem length and leaf length were worse Cheongju regional group in compared with that of Jecheon but leaf width was not different. Yields per 10a in both of Cheongju and Jechon were 1,600kg. After due consideration to seed tuver cost, approximately 40g is regarded as the most suitable weight for cultivation of Polygnatum stenophyllum Max.
