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.
