중ㆍ산간지대에 재배되는 참당귀의 화성억제에 의한 추대율 감소를 위하여 1992년 2월부터 1994년 11월까지 경북농림진흥원 북부시험장에서 육묘지대, 육묘지간 및 유기물 시용에 따른 화성 및 품질을 비교 분석한 결과를 요약하면 다음과 같다. 1. 육묘지대에 따른 추대율은 표고가 높을수록 현저히 낮았고, 아울러 지하부 생육 및 수량이 200, 400m인 지대보다 양호하여 참당귀의 육묘적지는 적어도 표고 600m 이상이 적당하다고 적당된다. 2. 중ㆍ산간 지대에서는 육묘기간이 짧아질수록 추대율이 현저하게 낮아서 수량은 증수되었지만, extract 및 decursin 함량은 육묘기간이 길어질수록 증가하여 육묘기간과 품질면에서는 반대되는 경향이었다. 3. 유기물 자원별에 따른 추대반응은 단비 시용구보다 유기물 시용구에서 추대율이 낮았으며, 특히 볏짚퇴비에서 가장 낮았고 수량 및 품질반응은 관행재배보다 유기물 시용구에서 양호하였지만 유기물 자원간에는 뚜렷한 차이를 보이지 않았다.
This study was carried out to investigate the effects of floral inhibition of An-gelica gigas NAKAI in the hilly altitude located in the Northern Gyeongbuk Province from Feb. 1992 to Nov. 1994. The results obtained were as follows ： As the cultivated areas are high, rate of bolting was significantly decreased, having high yield, good growth, and medicinal quality. It is considered that the optimal cultivating area was at least above 600m altitude. In the hilly altitude, the more shorten nursery period was, the more decreased rate of bolting was, it results in decreased yield, having no significant differences in contents such as extracts and decursin. In bolting response from temperature treatment of the seedlings, treatment of high temperature was significantly decreased floral induction, but rate of establishment was decreased by decayed root. Bolting rate at different organic resources has more reduced in single fertilization than that of in organic application, but among organic resources, compost of rice straw has the lowest bolting rate. As a result, yield and medicinal qualities at various organic resources were increased in application of organic resources which was no con-siderable tendency among organic resources.
