    Abstract


    “Bach Chi” is a medicinal plant and an essential constituent in traditional medicine. The plant has abundant flowers and fruits distributed on the different umbels. Time of flowering, number of umbels, umbel size, seed size and seed yields are different on each umbel position. Seed yield is highest on the secondary umbels (149.5 gr), but lowest on the central umbels. The aims of this paper are to determine whether the seed quality varies with umbel position and any effect of umbel position on growth, development and yield of Angelica dahurica Benth. Et Hook. F (Apiaceae) exists. Seeds were collected at five umbel types (center, primary, secondary, teriary and posterior umbels uppermost). Characteristics of individual umbels (duration of flowering, size) and plants (reproductivity, age, height, basal diameter) were recorded. The results showed that plants obtained from fruits on primary and secondary umbels grew much better (i.e. plant height, root diameter and yield) than those in collected from other umbels. The highest of root yield (3.16 ton/ha) and grade I percentage of roots (94.32%) were obtained from plants derived from seeds harvested on secondary umbels. The fruits on the primary, secondary and tertiary umbels are recommended for high quality of seeds to produce high quality of Bach Chi roots.
