Background : This study was carried out to investigate the differences of growth characteristics, photosynthetic rate and ginsenoside content of Panax ginseng C. A. Meyer according to the covering materials during house cultivation. Also the results of this study will be used as basic data for the standardization of ginseng house cultivation. Methods and Results : This experiment site was conducted from March to October, 2017 in the house located in Jinan - gun, Jeollabuk-do. The ginseng cultivar used in the experiment was a violet stem variant of 4-years-old. There are three kinds of covering materials used in the experiments: polyethylene (PE) film, scattering film, and blue-white film. PE film and the scattering film were first coated with 85% of light shielding net after the first installation, and then secondly coated with 75% and 30% of the light shielding net respectively in the middle of May when the house temperature reached 25℃. The blue-white film was cultivated after the initial installation without further treatment. The light transmittance of each covering materials were in the order of scattering film (14.5 ± 1.5%), blue-white film (10.0 ± 1.0%) and PE film (6.7 ± 1.0%). The average photosynthetic rate of each treatment was in the order of scattering film (2.94 μmol CO2/㎡/s), blue film (2.71 μmol CO2/㎡/s) and PE film (2.34 μmol CO2/㎡/s). Aboveground growth characteristics of ginseng were good in a scattering film and blue-white film. Root weights were found in the order of scattering film (47.1 g/plant) > blue-green film (41.3 g/plant) > PE film (37.6 g/plant). Conclusion : In order to select proper covering materials for ginseng house cultivation, the growth and photosynthetic characteristics of each treatment were compared with each other in order of scattering film, blue-white film and PE film. The photosynthetic rate of each treatment was measured according to the growing season. PE film was relatively low during the entire growth period. In the case of scattering film and blue-white film, the rate of photosynthesis was higher in the scattering film with high light transmittance until May, but showed a similar tendency after July. As a result, the difference in the growth characteristics of ginseng is thought to be due to differences in photosynthesis and assimilation according to the coating materials.

도시 내 연못을 조성할 때 필요한 기초 자료를 얻고자 주요 수생식물의 인공연못에서의 환경적응력, 피복도, 줄기 신장량, 관상가치를 조사하고, 식재 전 인공연못 내 토양과 수질 환경을 분석한 결과 다음과 같았다. 식재 1개월 후 9월 11일 조사에서 관상가치가 가장 좋았던 것은 수련이었으며 어리연꽃과 부들, 왜개 연꽃이 그 다음으로 높았다. 창포와 노랑어리연꽃은 다소 떨어졌으며 특히 창포는 9월에 잎 끝이 마르는 현상이 관찰되었다. 2개월 후에는 부들의 식재 1개월 후의 피복율은 노랑어리 연꽃이 85.2%로 가장 높았으며 다음이 어리연꽃으로 48% 이었다. 그러나 2개월 후에는 수련이 92.3%, 노랑어리연꽃이 91%으로 높게 나타났다. 연간 줄기 신장량 부들이 가장 컸고, 왜개 연꽃이 가장 작았다.
