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.
