차광과 유기물 시용이 더덕의 생육 및 향기성분에 미치는 영향
Effects of Shading and Organic Matter Applications on Growth and Aromatic Constituents of Codonopsis lanceolata
초록
본 연구는 자생지 야생더덕이 가지는 고방향성의 특성을 노지재배시 재배더덕에서도 고방향성을 갖는 재배기술을 확립하기 위하여 차광과 유기물 시용량을 달리하여 시험하였는 바 얻어진 결과를 요약하면 다음과 같다. 1. 차광조건에 따른 기상차이는 무차광구에 비해 차광(55%)에서 최고기온 6.1
The study was conducted to obtain the basic information on increasing aromatic degrees by shading and organic matter application on Condonopsis lanceolata. The result were as followings : Fresh root wt. in shading 55 % treatment was increased about twices, whereas fresh root weight in non-shading was decreased. But growth of ground parts such as vine length, leaf width, and leaf number was promoted under non-shading treatment. Macroelements such as K, Ca, and Mg, were increased in non-shading and higher organic matter application. The components such as crude protein, fiber, and ash were increased in the shading 55% treatment compared with non-shading. In the sixteen amino acids, arginine contents were the highest in non-shading and organic matter 30M/T. Recovery yield of essential oil was 0.005% in non-shading. The highest was organic matter 30M/T in the non-shading as 0.007%. Major aromatic constituents were 11 kinds of aliphatic alcohols such as I-hexanol, cis-3-hexenol, and trans-2-hexanal. As a result, major aromatic degree was higher in shading 55%, also increased in the much organic matter application. It was considered to be applied dense shading 55% and much organic matters to produce Condonopsis lanceolata plants which have high aroma and good quality.
