Effect of Shading Net Colors on the Growth and Saponin Content of Korean Ginseng (Panax ginseng C.A. Meyer)

해가림 피복물의 색상이 고려인삼의 생육 및 Saponin 함량에 미치는 영향

This study was conducted to define the effects of color of polyethylene (P.E.) net shading on the meteorological conditions under the shading growth status, photosynthesis and saponin contents of ginseng plant. Red and blue polyethylene net shading (4 fold) showed a good light intensity of ginseng growth, but red one not only increased air temperature but also resulted in early defoliation. Photosynthetic rate of ginseng leaves was increased in order of red, blue and black shade, Root yield and saponin contents were significantly increased red and blue net as compared with those of common straw shading. Blue color appeared to be most recommendable.
