Background : This study was conducted to determine the optimal ginseng greenhouse shading material for minimizing heat injury and maximizing the yield of ginseng plants in an effort to develop a stable ginseng cultivation technology and contribute to popularizing ginseng greenhouse farming. Methods and Results : Three different types of greenhouse shading material were used: polyethylene (PE) film + black screen (95%), light scattering film + black screen (75%), and blue-white vinyl. Important experimental details were implemented in accordance with the Analysis Standard of Agricultural Test and Research set out by the Rural Development Administration. The average greenhouse temperature for the period of May through October was 20.0℃ under the PE film + black screen, 20.2℃under the light scattering film + black screen, and 19.7℃ under the blue/white vinyl. High average photosynthesis rates of ginseng plants were demonstrated by light scattering film+black screen (2.35 μmole CO2/㎡/s) and blue-white vinyl (2.38 μmole CO2/㎡/s), with the PE film + black screen showing a considerably lower photosynthesis rate (1.55 μmole CO2/㎡/s). Heat injury occurred in 0.3%, 10%, and 0.1% of the plants grown under the PE film + black screen, light scattering film + black screen, and blue-white vinyl, respectively. As for the roots, the blue-white vinyl outperformed the other shading materials in root length (25.7 ㎝), taproot length (5.9 ㎝), and the number of fine roots (23.2). The blue-hite vinyl also yielded the greatest root fresh weight (30.2 g), followed by the light scattering film + black screen (29.1 g), with the PE + black screen yielding by far inferior average weight (22.0 g). The highest crude saponin content was yielded by the light scattering film+black screen (16.61 ㎎/g), followed by blue-white vinyl (11.36 ㎎/g) and PE + black screen (11.0 ㎎/g). Conclusion : Comparing the effects of three different shading materials on greenhouse-cultivated 3-year-old ginseng plants, the blue/white vinyl outperformed two other shading materials in most of the growth characteristics, whereas the and the light scattering film + black screen yielded the highest ginsenoside content.
