The chemical and morphological characteristics of 54 varieties of Paeonia lactflora were studied by growing them in Hokkaido Experiment Station for Medicinal Plants from 1980 to 1993 to give the following results. 1)The characters of aerial parts such as stem,petiole,petal, follicle and seeds were largely different from each other among the 3 and 5 year old plants of tested varieties. 2)They were classified into two types by the characters of root, the multi-root type having a large number of long roots mostly of medium and narrow diameters and the thick root type having a smaller number of roots with larger diameters. 3)Sprouting and flowering time also varied among the varieties, and the late sprouting varieties were late flowering. 4)The root weight per plant and the yield per unit area were 240-580g and 98-180kg/a, respectively,for 3 year old plants (planting distance ;60×50cm), and 470-1160g and 109-255kg/a, respectively,for 5 year old plants (planting distance;80×50cm). The percentage dry matter of roots was around 50%. 5)The paeoniflorin contents of dried roots of 5 year old plants were in the range of 1.32-4.47%(average 2.39%). The paeoniflorin content of 66% of the tested varieties exceeded 2.0%, the amount stipulated by JPX III.
