Background : This study examines the main growth characteristics, physiological stress, or diseases damage for 3 and 4-years-old ginseng in the new lines cultivated in Gyeonggi for development of new lines of Ginseng. Methods and Results : Eumseong 13, 14 and 15, which are two-years-old seedling in the new line ginseng were transplanted in 7 lines × 9 rows (70 plants)/1.62㎡ in 2015 along with Gumpoong and Yeonpoong as the control lines while Eumseong 16 and 17 as well as Chunpoong as the control line were transplanted in the same way in 2016. The ginseng shading was installed with the front post of 170 ㎝ high and the rear post of 100 ㎝ high using the rear line while as the sun blocking material, the aluminum shade plate was used. As for the new growth lines of 3 and 4-years ginseng in the new growth line, the aerial parts of the ginseng and underground part of ginseng were examined. In addition, the physiological stress such as the leaf discoloration, rusty root and root rot as well as the resistance against the disease were examined. It was found out that as for the aerial parts of 3-years-old ginseng in test line, Eumseong 16 and 17 were better in the growth than the control lines were while in 4 years old ginseng, Eumseong 13 and 14 were better in the growth than Gumpoong as the control line was. As for the root weight of the 4-years-old ginseng for the underground part, there was no significant difference compared with control line while in 3-years-old ginseng, Eumseong 16 and 17 were heavier. The leaf discoloration did not happen to both 3 and 4-years-old ginseng. As for the root rot, 3-years-old Eumseong 16 and 17 suffered less root rot in the same way as for the control line. 4-years-old Eumseong 14 and 15 had less root rot in the same way as for the control line. 3-years-old Eumseong 16 and 17 have less rusty root in the same way as the control line while as for 4-years-old ginseng, Eumseong 13, 14 and 15 showed a lot of rusty roots in the same way as the control line. Conclusion : Finally, considering the growth characteristics, physiological stress and root rusty of the aerial parts and underground parts of the ginseng, we selected Eumseong 16 and 17 as the excellent lines for 3-years-old ginseng.

Background : This study was conducted to select a optimal combination of LED light sources for stable production of sprout ginseng used as vegetables throughout the year. Methods and Results : The treatments to select the optimum LED light source for the production of functional sprout ginseng were ①Blue40%: Green40%: Red40% (B40 + G12 + R20 umol·m-2S-1), ②B50: G25: R10 (B50 + G8 + R5 umol·m-2S-1), ③B50: G20: R40 (B50 + G6 + R20 umol·m-2S-1), ④B35: G20: R35 (B35 + G6 + R18 umol·m-2S-1), ⑤B20: G0: R40 (B20 + R20 umol·m-2S-1), ⑥control (a general fluorescent lamp for plant cultivation, FL40W, PG, 35.0 umol). The ginseng seedlings used in the test were subject to preconditioning process for one week after the cold treatment at 4℃ for at least three months. The root media were composed of porous artificial soil 40% + peat moss 30% + perlite 20% + Vomito (brand name)10%. We planted 35 seedlings (planting density 5 × 7 ㎝) in a 480 × 380 × 295 ㎜ plastic box. The two liters of water were irrigated per a plastic box when water potential reached -33 kPa using a tensimeter. The cultivation room was maintained at 25℃ with 45% of the relative humidity, and 16 hours of lighting for growing conditions. The growing period was 40 to 60 days after planting. The results were as follows; the treatment of LED B50%: G25%: R10% (B50 + G8 + R5 umol·m-2S-1) increased the diameter of the sprout ginseng by 10.3% (4.95 → 5.46 ㎜), root weight 27.3% (1.1 → 1.4 g), fresh weight 38.9% (1.8 → 2.5 g) in comparison with the control. The contents of ginsenoside such as Re, Rg2, Rc, Rb2, and Rd increased 24.2% (24.8 → 30.8 ㎎/g). Conclusion : The optimal light source for sprout ginseng was LED B50%: G25%: R10% (B50 + G8 + R5 umol·m-2S-1), which increased sprout production by 38.9% in comparison with the control.

Background: This study was carried out to determine the best time for collecting ginseng berries without reducing the ginsenoside- Re content of ginseng roots, which are used as food, medicine, or cosmetic materials. Methods and Results: The test variety of ginseng used in this study was is Chunpung, which was collected from a 4-year-old ginseng field. Ginseng berries were collected at 7, 14, 21, 28, 35, 42, 49, and 56 days after flowering. The number of berry bunches per 1.62㎡ ranged from 43.4 to 61.4, while the weight of berries per 1.62㎡ was the greatest when they were collected 49 days after flowering. The root fresh weight per 1.62㎡ was increased by 0.21 - 1.00 ㎏ compared with that before the test, but root weight gain was decreased as the berry collection time was delayed. Total ginsenoside content of 4-year-old ginseng was the highest when berries were collected 7 days after flowering, while the ginsenoside-Re contents was the highest when collection was done 14 days after flowering. Conclusions: The most suitable period for ginseng berry collection was proposed to be from 14 to 21 days after flowering, as this is when the content of ginsenoside-Re, which is useful as a medicinal or cosmetic material, is still high and the ginseng root has not yet decreased in weight.

Background : This study was carried out to secure technology for stable production of ginseng by developing technology to reduce the high temperature in response to climate change. Methods and Results : Polyethylene film (PE film), scattering film and blue-white double-sided film (85% shading rate) were tested for ginseng rain-shielding materials. The shading materials used were a black shading net (90% shading rate) in the first, and an aluminum screen (40% shading rate) in the second. The first shading materials were installed on April 10 with PE film + black light shielding net, and scattering film + black light shielding net. As the treatment for high temperature injury relief, an aluminum screen was installed under a scattering film + black light shielding net and a blue-white double-sided film at a high temperature. The amount of transmitted light was 12.9% at scattered film, 14.5% at double sided film, and 12.5% at PE film when the primary rain-shielding material was covered. In secondary shading, scattering film + aluminum screen and blue-white double-sided film + aluminum showed 8.6% and 7.6% of light transmitting, respectively. In the case of temperature, the average temperature was lower than the outside temperature at the scattering film + aluminum screen, clear double sided film + aluminum screen and PE film recovery. The differences among the cultivars were significant in plant height, stem height, stem diameter, leaf length, leaf width and leaf area. There were significant differences in the plant height, stem height, leaf length, and leaf width between treatments, but there was no interaction effect between varieties and treatments. The interactions between treatments were found only in the number of brach root. Conclusion : High temperature damage was influenced by the amount of irradiation in the facility rather than the temperature, which was presumed to be due to the accelerated aging of the ginseng leaf as the light transmittance increased.

Background : This study researches on the microclimate, photosynthesis and growth characteristics for the development of shading materials proper for the wide and inclined ginseng cultivation facility which can respond to climate change and save labor. Methods and Results : The wide shading facilities were installed on the area of 1,000 ㎡ in 2014 and 4 facilities were installed on the test ginseng cultivation area. On Mar. 29, 2017, 2 blue shading nets [with the sun blocking rate of 85% (200 g/㎡) and 90% (220 g/㎡)] were installed each for 4 facilities. On June 26, 2017, the aluminum screen and black shading net (with the sun blocking rate of 40% each) were installed during the period of high temperature (30℃ or higher) for each facility. The maximum light intensity under the shading facility was high with blue shading net 85% and PE black shading net 40%, or blue shading net 85% and aluminum screen 40%, higher than other treatments. They were higher by 4.8 - 7.3%, 5.3 - 7.8% each in July and August. Among the coating materials for reducing the high temperature, the aluminum screen coating had less water leakage in early July, late July, mid-August and late August when the precipitation was more than 100 ㎜. The death of the aerial part of ginseng occurred less until October. The growth of the aerial part of 4-year ginseng was better in blue shading net 85% and PE black shading net 40%, blue shading net 85% and aluminum screen 40% or blue shading net 90% and PE black shading net 40% than in blue shading net 90% and aluminum screen 40% The photosynthesis rate was the highest in June with 3.67 μmol CO2/㎡/s under the blue shading net 90% and aluminum screen 40% and with 3.55 μmol CO2/㎡/s under blue shading net 85% and PE black shading net 40% for K-1. As for the land races ginseng, it was the highest with 3.55 μmol CO2/㎡/s under the blue shading net 85% and PE black shading net 40%. For the growth of the underground part of the 4-year ginseng, the blue shading net 85% + PE black shading net 40% or the blue shading net 85% + aluminum screen 40% was the best with respect to the growth of the ground part of the ginseng such as the length of root, the length of main root, diameter of root and weight of root than other treatment. Conclusion : Best coating materials for the wide shading facilities are the blue shading net 85% and aluminum screen 40%.
