Abstract
Stem length, main root length and main root diameter showed rapid increasement in two-years-old and three-years-old peony. And there after, the increasement was almost finished. Occurrence of disease was increasing every cultivated year, especially the development of leaf spot was most serious. In propagation by root dividing method, the radix yield (kg/10a) was increasing every cultivated year. However, the difference of radix yield at four and five-years-old peony were not significant. The radix yield of four-years-old peony was higher 26% than three-years-old one. As cultivated year goes by, content of paeoniflorin was increasing then the content was highest at four-years-old peony (4.06%). In 1995, the content, had no certain tendency, was highest at three-years-old peony (3.14%). At hot air drying, browing of peony radix was increasing every cultivated year. If we consider radix yield and color, three-years-old peony was proper object of harvesting.
다년생(多年生) 약용작물(藥用作物)인 작약(芍藥) (P. lactiflora Pall.) 분주묘(分株苗) 2, 3, 4, 5년생(年生)에 따라 변화하는 생육특성(生育特性) 및 근수량(根收量), 병해(病害) 발생정도(發生程度), Paeoniflorin 성분(成分)의 함량변이(含量變異)를 조사하여 작약근(芍藥根)의 상품적 가치를 증가시키는 품질 규격화를 위한 기초자료를 얻고자 의성작약(義城芍藥)을 공시품종(供試品種)으로 하여 시험을 실시하였던 결과를 요약하면 다음과 같다. 1. 재배년수(栽培年數) 경과에 따라 경장(莖長)과 지하부의 주근장(主根長) 및 주근경(主根莖)은
