Background : The roots of Codonopsis pilosula (Franch.) Nannf are used as medicines such as expectorants, and they are edible. Codonopsis pilosula (Franch.) Nannf currently has a very small cultivation area, and there are no breeding cultivars, most of the native species are cultivated in the farm house. Therefore, it is important that identification of collecting species characteristic in order to breeding strategy. In this study, morphological features of the leaves and stems of the collecting species in the area were observed. Methods and Results : The morphological characteristics of mansam collected from three areas including Cheolwon (41 accession), Jeongseon (19 accession), and Pyeongchang (15 accession) were investigated at the flowering stage on leaf and stem. As a result of investigation of leaf characteristics, The leaf shape was the most frequent with 78.9% in the kidney type, 8.5% in the cardiac type, 7.0% in the wide-elliptical type, and 2.8% in the egg and egg-oval type. The leaf length was the most frequent with 67.1% in case of short, 28.6% in case of middle, and 4.3% in case of long. The leaf width was 67.1% in case of middle, 30.0% in case of broad, and 2.9% in case of narrow. Leaf hair was 47.1% in case of plenty, 27.1% in case of middle, and 25.7% in case of small number. The degree of greenness of the leaves was 60.0% in case of middle, 31.4% in case of darkness, and 8.6% in case of lightness. The degree of pigmentation of anthocyanin in petiole was 41.4% in case of lightness, 31.4% in case of darkness, and 27.1% in case of middle. As a result of investigating the characteristics of stem, The presence and absence of hair on the stem was 95.7% in case of little, 2.9% in the middle, and 1.4% in case of plenty. The degree of staining of anthocyanin in the stem was 42.9% in case of middle, 30.0% in case of darkness, and 27.1% in case of lightness. Conclusion : We intend to use this data as a basic data for cultivating varieties by supplementing investigation of traits such as expansion of collection area and investigation object and flower shape in the future.

Background : This study was carried out to introduce Atractylodes macrocephala as a new income element in Gangwon area and to develop the technology necessary for stable quality seedling production. Methods and Results : For the production of high quality seedlings of Atractylodes macrocephala, seedling growth characteristics were investigated according to the types of plug cell size and seedling raising period. Atractylodes macrocephala seeds were sown on February 14, 2018 in 72, 105, 128, 162, and 200 plug trays. The emergence period after sowing was March 2, and the final occurrence rate was 76.6 - 79.5%. The number of days of emergence took 18 to 20 days from sowing date. Growth of seedlings tended to be better with less number of plug trays, such as seedling height, seedling width, leaf length, leaf width and leaf number. On the other hand, roots (net formation) increased rapidly as the number of plug trays increased. After 60 days, the matured seedling rate was good at 75.5 ± 8.4% for the 200 plug tray and 72.5 ± 4.1% for the 162 plug tray. The net formation ratio of matured seedling was the best in 60 days of seeding in 162 plug trays. The rooting rate was 98.0 ± 2.1 - 99.3 ± 1.2% when seeded for 60 days or more regardless of the type of plug tray. Conclusion : In order to produce efficient and stable seedlings in the cultivation of Atractylodes macrocephala in Gangwon area, it was considered to be advantageous for 60 days of seedling settling in the plug trays of more than 162 and less than 200.

Background : Atractylodes macrocephala is a perennial herbaceous plant belonging to the family Asteraceae and should be cultivated in field soils with good water dripping due to plant characteristics. However, cultivating farmers mainly have recently been cultivated in paddy soil due to their regional characteristics, which causes the decrease in yield due to poor drainage. Therefore, this study was carried out to investigate the cultivation in high ridge and subsoil breaking effect for stable paddy soils cultivation technology of A. macrocephala. Methods and Results : Soil was paddy soils in the fall of 2017, and the pH (1 : 5) was 6.61 ± 0.15 as a result of chemical and physical properties. EC was 0.49 ± 0.05 dS/m, and organic matter content was 28.69 ± 69 g/㎏ and effective phosphoric acid was 306 ± 17.8 ㎎/㎏. As a result of the soil layering survey, the surface layer was 0 - 26 ㎝ deep as paddy soil mounded with sandy loam in the past. In the surface layer, there was a light layer after 17 ㎝ depth, and volume density was 1.71 ± 1.3 g/㎤. The porosity of the plow pan was 33.41 ± 2.34%. The cultivation methods were cultivation in high ridge (30 ㎝ or more) and level row (10 ㎝ or less) at 2 levels and 3 repetitions. In subsoil breaking, the depth of the plow pan was increased from 17.1 ± 0.5 ㎝ before treatment to 31.1 ± 3.6 ㎝ after treatment and the hardness was 24.8 ± 1.5 ㎜. In the case of rotary plowing, the depth of the plow pan was 17.1 ± 1.9 ㎝ before treatment and 26 ± 2.4 ㎝ after treatment and the hardness was 25.8 ± 2.9 ㎜. The medium growth characteristics of A. macrocephala per treatment showed the tendency of increase in plant length, culm length, number of nodes, number of leaves, and fresh weight in level row cultivation after subsoil breaking. Root growth of cultivation in high ridge after subsoil breaking tended to be good with rhizome weight of 11.6 g per hill. The survival percentages were 98.8 - 100% and the bolting rate was 93.4 - 96.2% Conclusion : In cultivation in high ridge after subsoil breaking in the paddy field of Gangwon area, the decrease of yield of A. macrocephala due to drainage was expected to be alleviated, but final conclusion should be drawn after analyzing soil temperature and soil moisture data.
