Abstract
This study was conducted to investigate the effects of cultural soil textures on growth and quality of Glycyrrhiza uralensis Fischer from 2009 to 2010. The obtained results from this study were summarized as follows; The growth of stem and leaf were superior to one year old G. uralensis, and surface runner and root growth tended to be better in 2 years old G. uralensis. The weight of stem and leaf were heavy in sandy loam, and plant height, branches, stem diameter in sandy clay loam were better than other soil texture. The growth characteristics, such as length, number and weight of surface runner, was better in order of sandy clay loam > sandy loam > loamy sand. The length of main and lateral root was longer in loamy sand soil than other treatments, and the diameter of main and lateral root was more thicker in sandy loam than others. The number of lateral root was higher in the sandy loam than other treatments. The yield of main and lateral root was in order of sandy loam > sandy clay loam > loamy sand soil. Marketable root yield of one year old and two year old G. uralensis were increased 57% and 71% in sandy loam compare to a loamy sand as 204 kg/10 a, respectively. The content of glycyrrhizinic acid was the hightest as 1.62% in sandy clay loam soil in one year old, and as 1.58% in sandy loam soil in two years old of G. uralensis, respectively.
재배토성이 감초 생육 및 품질에 미치는 영향을 구명코자 2009년부터 2년간 시험을 수행한 결과를 요약하면 다음과 같다. 1. 재배년생별 생육중 경엽은 1년생, 포복경 2년생, 근은 2년생에서 양호한 경향을 보였으며, 토성에 따라서 경엽중은 사양토에서 무거웠고, 초장, 분지수, 경태는 사질식양토에서 우수하였다. 2. 포복경의 길이, 수, 무게 등 생육은 사질식양토 > 사양토 > 양질사토 순으로 좋았다. 3. 주근과 지근의 생육은 양질사토에서 길었으며, 주근경, 지근경은 사양토에서 굵었다. 지근수는 사질식양토에서 다소 많았다. 4. 근 수량은 주근, 지근 등에서 사양토 > 사질식양토 > 양질 사토 순으로 많으며, 1년생과 2년생 근 상품 수량은 사양토에서 양질사토 204 kg/10a 대비 57%, 2년생은 71% 각각 증수하였다. 5. 글리시리진(glycyrrhizinic acid)의 함량은 1년생은 사질식 양토에서 1.62%, 2년생은 사양토에서 1.58%로 가장 높았다.
