작약(芍藥) 분주묘(分株苗)의 활착불량(活着不良) 실태(實態)와 원인(原因)을 구명하기 위하여 시험 연구한 결과는 다음과 같다. 1. 작약 분주묘의 농가 포장 활착 실태 조사 결과 활착불량 피해율은 32%에 이르고 외형적 피해 실태는 무출현(無出現) 5.6%, 출현후(出現後) 고사(桔死) 20.7%, 출현후(出現後) 위조가 5.7%였다. 2. 활착불량 피해 정도별 농가 실태는 71%이상 피해를 본 필지가 4%, 70~41% 피해는 13%, 40~11% 피해는 45%로 많은 면적이 활착불량으로 인하여 결주가 된 것으로 나타났다. 3. 농가포장에서 정식시기에 따른 활착불량(活着不良) 피해율(被害率)은 가을 정식의 경우 18.2%인데 비하여 봄정식은 42.9%로 매우 높았고 실생묘(實生苗)보다는 분주묘(分株苗)에서 피해가 더 많았다. 4. 분주후 정식까지의 경과 일수가 길수록 생육과 수량이 크게 떨어졌고 봄정식시는 활착율이 66.7%로서 매우 낮았으며 종근소독과 토양살충제 혼용처리시 생육과 활착이 양호하였으나 무처리는 불량하였다. 5. 작약 분주묘의 활착불량(活着不良) 주원인(主原因)은 뿌리썩음병(Cylindrocarpon sp.)과 불량종(不良種) 묘(苗)로 나타났다.

The experiment was conducted to find causes of rooting failure in divided crown of peony cultivation. The results were as follows : In farmer s fields, damage rate of rooting failure in divided crown of peony was 32% as non-sprouting 5.6%, withering after sprouting 20.7%, and wilting after sprouting 5.7%, repectively. Damage degree in farmer s fields was followed, above 70% by 4%, 41 to 70% by 17%, 11 to 40% by 45% per total field area, respectively. It was caused by rooting failure. Damage rate of rooting failure as affected by different planting time was 18.2% for planting in autumn, 42.9% for planting in spring, and damage in divided crown was higher than in seedling. As periods to planting were prolonged, growth and yield were larger poorly, treatment with seminal-root sterilization and soil insecticide showed good growth and rooting but untreated control was very poor. Main cause of rooting failure in divided crown of peony was disease, Cylindrocarpon sp. and low quality of seeds.
