초록

Background : Panax ginseng C.A. Meyer belong to Panax species Araliaceae and a perennial plants. It grows in Far East Asia such as the Maritime province in Russia, the Manchuria reg ion of China, and the Korean peninsula. Panax ginseng C.A. Meyer is cultivated by seed sow ing or transplanting-culture, but seedling standing rate is as low as 50%. Therefore, it is impo rtant to increase seedling standing rate. This study was performed to research of plug-seedling cultivation techniques of Panax ginseng C.A. Meyer for increase of seedling standing rate.
Methods and Results : Testing material, Panax ginseng C.A. Meyer seed, was sown on 5 kin ds of seedling trays (72, 105, 128, 162, 200 cells) in the middle of February 2016. It was gr own in the seedling green house in medicinal plant resources research department of Gyeongs angnam-do Agricultural Research and Extension Services. Four months after sowing, the seedli ng growth characteristics such as seedling standing rate and seedling withering rate were inves tigated. After transplanting in the mountain area of Hamyang-gun, growth characteristics of the root length, root weight, and other factors were investigated at the beginning of November. A s a result, seedling standing rates were 50.1% to 56.2% and seedling withering rates were 25. 2% to 35.9%. Among the five ports, the seedling standing rate of 105 cells and 72 cells was 56.2% and 55.7%, which were higher than others. In the case of 105 cells, however, seedling withering rate was 35.1% higher than that of 72 cells. Seedling leaf length and width were lo nger at 72, 105, 128 cells than at 162, 200 cells and seedling root length, root fresh weight and shoot fresh weight were the highest at 72 cells. Roughly, the more tray cells, the less se edling growth. After harvesting, among the five ports, root fresh weight and root dry weight per 1 hill of 128 cells were 0.36 g and 0.11 g, respectively, which were higher than those of other cells.
Conclusion : The growth characteristics of Panax ginseng C.A. Meyer considering the seedling standing rate and seedling withering rate, among the five ports, 72 cells was most suitable. A mong the five ports, considering root fresh weight and root dry weight after harvesting, 128 c ells was most suitable.
