Yield and Red Ginseng Quality of Super-aged Root of Panax ginseng

초고년근 고려인삼의 수량과 홍삼적성

Seven year old ginseng was investigated for yield , the relationship between yield and percent missing plant and red ginseng quality. Yield was 2.06 kg/kan (3.3 m2) and percent missing plant was 27.1%. The highest yield plot showed 3.58 kg/kan and potential yield appeared to be 4.5 kg/kan. Yields of 1st, End and 3rd line showed significant negative linear correlation with percent missing plant. Potential yield without missing plant was in decreasing order of 1>2)3>5) 4 and negatively correlated with unit yield decrease per percent missing plant. Potential yield of 1st line was 6.56 kg/tan. Soft X-ray absorbtion characteristics was not different from that of 6 year old ginseng. Red ginseng grade and percent occurence of red ginseng quality factors were not different from those of 6 years old ginseng. The weight of red ginseng per root was much greater than that of 6 years ginseng. In view of yield and quality of fresh and red ginseng the production of red ginseng from 7 years old ginseng appears to be economically feasible.

7년근 포장에서 작항별로 행별 수량을 조사하였으며 지상부 생육상태별로 홍삼을 제조하였다. 수삼수량은 2.06kg/칸이고 결주율은 27%였다. 1, 2, 3 행의 행내에서 수량과 결주율과 유의 상관이 있었으며 잠재수량이 높을수록 단위결주당 감수율이 컸다. 결주가 없는 때의 잠재수량은 4.5kg/칸이었으며 가장 높은 구의 실제 수량은 3.58kg/칸이었다. 7년근 원료삼의 연 X-선 흡수특성이나 홍삼품질과 품질저해요인 발현율도 6년근과 크게 다르지 아니하였다. 7년근의 홍삼은 대편 천지삼의 생출이 많은 점이 특징이었으며 이로부터 초고년 초대편 홍삼상품의 개발은 경제성이 높을 것으로 보인다.
