Studies on Growth Responses and Yields of Panax ginseng C. A. Meyer Grown under Hydroponic Culture with different Temperatures and Growth Stages

Abstract

: This study was carried out to have the basic and applied informations relating to increase the productivity and quality of ginseng. 2 years-old ginseng was cultivated under hydroponic culture with the controlled environment conditions in a greenhouse. Major growth characters and yields were investigated with two different temperatures and several growth stages. The plant height and stem diameter were higher at low temperature than those at high temperature. They were not clearly different with six different growth stages. The root length was not clearly different between two temperatures; however it was continuously grown from June until August. The root diameter was higher at low temperature than that at high temperature. It was rapidly increased from June until August. The length, width, and area of leaf were higher at low temperature than those at high temperature. The fresh and dry weights of different plant tissues were also heavier at low temperature than those at high temperature. The moisture content of ginseng root was continuously decreased from June until August. The yield of ginseng was higher at low temperature compared to that at high temperature. The cultivating conditions in hydroponic culture of ginseng, especially temperature, would be an important factor to have better growth and production.

Investigation of Ginsenosides and Antioxidant Activities in the Roots, Leaves, and Stems of Hydroponic-Cultured Ginseng (Panax ginseng Meyer)

“…2A), which is related to the cultivation characteristics of ginseng. The 2-years-old ginseng are reported to display the most robust growth at 14~20°C and 60~70% humidity (Lee et al, 2012). The strongest growth periods of hydroponic-cultured ginseng used in this study ranged from 8 to 9 weeks in March, 4 to 5 weeks in May, and 5 to 6 weeks in August.…”

“…또한, ginsenoside Rb1은 c-Fos 발현을 촉진하여 에너지 항상성을 유지시키고, phosphatidylinositol 3-kinase/Akt signaling pathway와 시상하부에서 neuropeptide Y gene expression을 억제하여 체중 감량 효과와 항당 뇨 효과를 갖는 것으로 보고된 바 있다 (22). 최근 수경재배 방법 을 이용한 인삼 재배가 시도되고 있음이 보고되고 있는데 (23), 이 방법으로 인삼을 재배할 경우 생육기간이 단축되고, 휴작 기간이 없으며, 단위면적당 생산성이 높아질 것으로 제안되고 있다 (24). 수경재배 Mineral mixture according to AIN-76…”
