연구보문 : 적심정도가 감초의 생육 및 품질에 미치는 영향 = Research Papers : Effect of Top-Precision on Growth and Quality in Glycyrrhiza uralensis in Korea

국문 초록 (Abstract)

감초의 적심정도가 생육 및 품질에 미치는 영향을 구명하고 감초 재배의 기초 자료를 얻고자 적심정도를 경장의 20% 등 4처리를 두어 2008년부터 3년간 시험한 결과는 다음과 같다. 1. 적심 유무에 따른 감초 경엽 생육은 초장, 분지수, 절수 및 경엽중은 무적심에서 양호한 경향이었으나, 경태는 가늘은 경향이었고, 적심정도 간에는 경태를 제외하고 적심비율이 적을수록 양호한 경향이었다. 2. 포복경 생육은 무적심 처리에서 양호한 경향이었으며, 적심정도에 따라서는 적심비율이 적을수록 양호한 경향이었다. 3. 뿌리의 생육은 무적심에 비하여 적심처리에서, 적심정도 간에는 주근장과 지근장은 20% 적심에서 길었으나, 다른 근생육은 40% 적심에서 양호한 경향이었다. 4. 근수량은 40%>60%>20%>무적심 순으로 많았으며, 40% 적심시 상품 근수량이 무적심 300kg/10a에 비하여 25% 증수 되었다. 5. 글리시리진(Glycyrrhizinic acid)의 함량은 20%와 40% 적심에서 무적심 1.35% 대비 각각 0.31%, 0.09% 높았다.

Growth and quality according to top-precision degree of Glycyrrhiza uralensis Fischer were tested by 4 treatments including 20% rate cutting of branch-top during 3 years from 2008. Growth above ground part of Glycyrrhiza uralensis Fischer with or without topping-plant height, branch number, node number, weight of stem and leaf-was good tendency without topping but stem diameter was less. growth above ground part among topping ratio was the less topping ratio the better except stem diameter. Growth of surface runner was good tendency without topping. growth of surface runner among topping degree was the less topping ratio the better. Root growth was higher without topping compare to topping. Length of main and supporting root among topping ratio was longer in 20% topping treatment but root growth except root length was good tend in 40% topping. Weight of root was high 40%>60%>20%>no topping the order, marketable yield in 40% topping of height was increased by 25% compared with no topping as 300kg/10a. content of Glycyrrhizinic acid with 20% and 40% topping of height was increased by 0.31% and 0.09% compared to no topping as 1.35% respectively.
