Comparison of Growth Characteristics and Quality of Korean Ginseng (Panax ginseng C.A. Meyer) by Different Shade Materials

This research investigated growth of ginseng regard to sunshade materials and micro metrological phenomena under the sunshade material to product high quality ginseng. Followings are results of investigation of active ingredient from raw ginseng producted under the sunshade materials. The highest temperature under the sunshade material from June to August was measured from a Three-layered blue and one-layered black polyethylene net (TBOBFN) followed by a aluminium-coated polyethylene sheet (ACPS) and blue polyethylene sheet (BPS). The highest light penetration of $381.7{\mu}mol/s/m^2$ was obtained from the BPS at August, also the temperature was highest at the ginseng field. Growth of above ground part of 2~3 year old ginseng under the ACPS was the highest, followed by the ACPS and the BPS. In case of 4 year old ginseng, the ACPS and the BPS was the same, followed by the TBOBPN. Root length and diameter of 2~3 year old ginseng showed difference among treatments, but 4 year old ginseng was not showed difference. Meanwhile, the highest amount of root of 4 year old ginseng of $896g/m^2$ was obtained from ACPS. The total amount of ginsenocide of 4 year old ginseng under the ACPS was highest, followed by the BPS and the TBOBPN. Chromaticity of ginseng root under the TBOBPN was highest, followed by the ACPS and the BPS.

해가림자재 종류별 고려인삼의 생육과 품질특성 비교

고품질 우량인삼 생산을 위한 해가림자재별 인삼의 생육상황과 해가림 아래의 미기상 변화를 조사하였고, 각각의 해가림자재에서 생산된 수삼의 유효성분들을 조사 분석한 결과, 6~8월까지의 해가림자재별로 온도는 차광지>차광판>차광지 순이었고, 투광량도 차광지가 8월에 $381.7{\mu}mol/s/m^2$로 인삼포내 온도가 가장 높은 원인이었다. 2~3년 인삼의 지상부 생육은 차광망>차광판>차광지 순이었으며, 4년근은 차광판=차광지>차광망 순으로 좋았다. 4년근 인삼의 진세노사이드 총함량은 차광판>차광지>차광망 순으로 많았으며, 수삼의 색도는 차광망>차광판>차광지 순으로 높았다.
