Effects of Light Inensity and Quality on the Growth and Quality of Korean Ginseng (Panax ginseng C.A. Meyer) I. Effects of Light Intensity on the Growth and Yield of Ginseng Plants

광량 및 광질이 고려인삼의 생육과 품질에 미치는 영향 I. 광량이 인삼생육 및 수량에 미치는 영향

This study was conducted to know the elects of light intensity of polyethylene net shading on the growth status, photosynthesis and root yield of ginseng plants. Polyethylene net shading of loft transmittance was the best one among light intensities of polyethylene net used in view of photosynthesis and decreasing of early leaf defoliation. According to increase of light intensity under the shading chlorophyll contents of ginseng leaves were decreased. As it was increased over 2 mg/g Photosynthesis and total saponin of leaves showed on the decrease remarkably. The rate of alternaria blight of ginseng plants showed the positive correlation between light intensity and leaking rate. The shading of 10% transmittance in root yield was increased by 40% in 6-year-old ginseng plant as compared with common straw shading, due to decreased missing plant and increased root weight.
