작약 분주묘의 크기에 따른 생육과 품질을 조사하여 재배법 개선의 기초자료로 활용코자 1994년 10월부터 3개년간 의성에서 의성작약을 공시하여 수행한 시험 연구 결과는 다음과 같다. 1. 작약의 분주묘 크기가 클수록 출현을 및 활착율은 높은 경향이 었으며 지상부 생육도 양호하었다. 2. 소묘
This experiment was conducted to determine the effect of different size of divided crowns used as planting material on the growth characteristics, yield and quality of Paeania lactiflora Pallas (P. lactiflora Pallas). The ratio of sprouting, rooting, and growth of above-ground parts increased with the increase of crown size. The root yields of under-ground parts from different size of divided crown were 2,674kg/10a for large size and 2,304kg/10a for medium size and the yield index was improved by 39% and 30%, respectively, compared to 1,921kg/10a in small size. Commodity ratio of roots over 10mm in diameter were higher for large and medium size crown: index increased by 26 % and 11 %, respectively, compared to 1,406kg/10a in small size. Income analyzed by crown size was \ 1,133,000 per 10a at the use of small crown size but income were increased 25 % and 48 %, respectively. by using medium and large size crown as compared with small crown.
