Abstract
This study was carried out to determine plant growth and bolting characteristics of Angelica gigas. Three varieties and/or lines Manchu bolting resistant variety, AGJ90-1 medium type line, and bolting Jinbu local were used for field trial in Suwon. FIve different transplanting times were applied on March 25, April 5, April 15, April 25, and May 5th. Survival rate was decreased by the delayed transplantation and it affected after April 25th respectively. Plant growth by the early transplantation showed the best growth during the beginning stage and recognized signifiquence but not by the late transplantation. Bolting rate revealed severe different by the variety and line, it ranged from $10{\sim}8.1%$ of Manchu, $5.9{\sim}20.3%$ of AGJ90-1, and $58.5{\sim}74.6%$ of Jinbu local clearly. By the treatment of transplantation time bolting rate was different, early plantation showed high bolting rate compare to the late plantation from the all of tested variety and lines. Bolting response according to the transplanting time, bolting resistant variety showed insensibility and boling line showed sensitive response. In Manchu root yield was best when planted on April 5th as 389 kg /10a, in case of AGJ90-1 was determined 377 kg/10a when planted on April 15th, and Jinbu local root yield was showed 133 kg/10a planted on April 25.
참당귀 품종별 정식시기에 따른 생육 및 추대반응을 구명하고자 수행한 시험결과를 요약하면 다음과 같다. 1. 생존율은 만추당귀, AGJ90-1, 진부재래 공히 정식시기가 늦어짐에 따라 생존율이 낮아지는 경향이었으며 4월 25일 이후 정식에서는 현저히 낮았다. 2. 초기생육은 품종별 모두 조기 정식에서 생육량이 많고 만기 정식에서 생육량이 적어지는 경향으로 정식시기별 유의차가 인정되었으나 생육후기에는 유의차가 인정되지 않았다. 3. 품종별 추대율은 내추대성인 만추당귀는 $1.0{\sim}8.1%$, 중간형인 AGJ90-1은 $5.9{\sim}20.3%$, 추대성인 진부채래 $58.5{\sim}74.6%$ 범위로 품종의 추대성 정도에 따라 추대율의 차이가 크게 나타났다. 4. 정식시기별 추대율은 만추당귀, AGJ90-1, 진부재래공히 조기정식에서 추대율이 높고 만기정식에서 낮아지는 경향이었다. 5. 품종의 정식시기별 추대반응은 내추대성 품종은 둔감하게 반응하고 추대성에서는 민감하게 반응하였다. 6. 10a당 수량은 만추당귀는 4월 5일 정식에서 389 kg으로 가장 높고, AGJ90-1은 4월 15일에 377 kg, 진부재래는 4월 25일에 133 kg으로 가장 높았다.
