Background: Angelica gigas Nakai, that belong to the Umbelliferae family, is one of the traditional medicinal plants in Korea. Its roots have been used to treat gynecological diseases. In this study, growth characteristics and index components were compared with the forest microclimate at several forest sites.
Methods and Results: A. gigas was planted in three climatic zones according to the temperature (southern temperature zone - Hamyang, central temperature zone - Bonghwa, and northern temperature zone - Jeongseon) and growth characteristics were investigated in comparison with the forest microclimate. Our results indicated that the root diameter and length, and fresh and dry weight were the highest in Jeongseon. The total content of decursin was the highest in Jeongseon (9.52%), followed by those in Hamyang (8.07%) and Bonghwa (7.48%), respectively. Additionally, the yield of decursin (1.39 g) was the highest in Jeongseon.
Conclusions: The yield and index components were influenced by the microclimate in the forests, and it was assumed that high altitude and low temperature affected the increase in growth and index components. These results will be useful as basic data to study the correlation among environmental conditions, growth, and index components.
