Effect of Light Intensity and Temperature on the Growth and Root Yield of Panax ginseng
광도와 온도가 인삼의 생육 및 수량에 미치는 영향
Abstract
This study was conducted to investigate the optimum temperature and light intensity of photosynthesis and transmittance in the shade for better growth and root yield of ginseng. The 3-year-old ginseng plants grown under the shade of 5, 10 and 20% transmittance did not show any significant difference in the stem length, stem diameter, leaf area and root length. The root diameter markedly increased under the shade of 10% and 20% transmittance, and the root was the heaviest under the shade of 20% transmittance. The 6-year-old ginseng plants grown at 20% transmittance showed the largest root diameter but the root length was not influenced by transmittance. The root was heaviest in the shade of 20% transmittance.
3년생 인삼에서 5, 10 및 20% 투광율 일복간에는 경장, 경직경, 엽면적, 근장의 차이가 없었고 근직경은 10% 및 20% 일복구에서 현저히 굵었으며 20%구에서 근중이 가장 무거웠다. 6년생 인삼에서도 20% 일복구에서 가장 근직경이 굵었고 근장은 투광율에 영향을 받지 않았으며 20% 투광 일복하에서 가장 근중이 무거웠다 근중의 증가를 위한 최적 일복투광량은 3년근에서는 18.13% 그리고 6년근에서는 21.50% 추정되었다.
