This study was investigated to know about the stages of flower bud development and the effects of natural and artificial cold treatment on flowering of herbaceous peony. Developing buds of Paeonja lactㅑflora Pall. var. Taebaek were observed since Jun. 17 and peony plants were forced since Nov. 27 in the green house with two weeks interval, and other plants were forced after cold treatment in
for 1, 2, 4, 6weeks. Differentiation of vegetable part in peony buds was started in early June, and floral part was differentiated in September and their differentiation was continued to shooting in early spring. Buds of peony were sprouted and flowered when it was forced on Dec. 4. Days to shooting were decreased with delay of forcing time from early to late of December, significantly. Two weeks for cold treatment were enough to break dormancy of peony and days to shooting of the cold treated were significantly shorter than the untreated in the same forcing times

To establish appropriate seed production system in Angelica gigas. Germination of seeds with different bolting years and the growth characters of plants originated from these seeds were investigated. Seed weight from 1st year bolting plant was highest. In germinability according to seeds with different bolting years, seeds from 1st year bolting plant were higher than seeds from 2nd, 3rd years bolting one. In growth characters of plants originated from seeds with different bolting years, as the bolting years became late, root growth increased and top growth decreased, therefore T/R ratio decreased.

We investigated the structures of floral organs and the developmental process of each floral organs in Bupleurum falcatum. The overall size of a floral was about 2mm. The lengths of ray, pedicel, pistil and stamen were 22.5mm, 3.6mm, 1.0mm and 1.3mm respectively. The ovary surface was 0.9mm in length and 1.4mm in width. And the developmental periods of each floral organs were as follows; 1 through 6 days in stamen emergence, 6 through 9 days in petal detachment and pistil emergence, 9 through 16 days in pistil maturation, and above 16 days in pistil degeneration after onset of flowering. This plant was admitted to be a allogamous plant, especially with the protandry form of dichogamy.

The study was conducted to determine the effects of an optimum irrigation time as affected by the different soil textures in Dioscorea batatas DECNE. Water content change was decreased following orders, non - irrigation > July 15 > Aug. 15 > irrigation of two times (July 15 following Aug. 15). It was appeared that sandy loam texture was sharply decreased compared with the loam texture in water loss. Dan-Ma was preemergenced about 6 to 8 days without soil texture. Epiphytic amounts in both Dan-Ma and Jang-Ma were about two times increased at tubberous fomation and enlargement stages comparing non - irrigation. In tuber yield without soil texture, Jang-Ma was increased compared with Dan-Ma and tuber yield in loam soil texture was promoted. As a result, it was concluded that sandy loam texture has more compatible than loam soil texture.

This study was carried out to select proper intercrops in peony cultivation because peony is damaged easily by disease and cannot make proper income with it's single crop system, so it needs rational intercropping system to raise it's productivity and income. The results of this study are as follows. The kinds of soil nematodes were Meloidogyne sp, Pratyienchus sp, Aphelenchoides sp, Ditylenchus sp, Xiphinema sp, and damaging dominant nematode was Meloidogyne sp. The density of Meloidogyne sp wa suppressed remarkably in the combination of peony+sesame, and peony + job's tears. This study shows that sesame and job's tear were most resistant crops to the IvIeloidogyne sp. The quanity of herbaceous peony was the best in the combination of peony+red pepper. The results of income analysis per lOa for three years shows next conclusion. Peony+red pepper combination and peony+ sesame combination were most effective when it's compared with single cropping of peony (1,490 thousand won). But red pepper was damaged easily by soil nematode, therefore, sesame was the most stable and high yield crop as a intercrop in the cultivation of herbaceous peony.

This experiment was carried out to investigate the effect of planting date and planting density on yield and yield components of Fritillariae bulbus from 1989 to 1991. The Chungbuk local variety was used, and the experimental materials were planted six times with 10 days interval from Aug. 20 to Oct. 10. 33, 22, 17 and 13 bulbs were planted by the square meter, respectively. The compound fertilizer for garlic
was applied by 80kgs to the 0.1ha before planting. The experimental design was randomized block design with 3 replications. As the planting dates were earlier, the emerging dates were earlier, too. But the delay of 50 days in the planting affected to the delay of 14 days in the emerging dates. The plant height was 22.7cms in the Aug. 20 plot. As the planting were later, the plant heights were shorter by
than that. As compared with the 829kgs by the 0.1ha of Aug. 30 plot, the others recorded 1 percent increase in the Aug. 20 plot, 4 percent decrease in the Sep. 10 plot, 26 percent decrease in the Sep. 20 plot, 35 percent decrease in the Sep 30 plot, and 38 percent decrease in the Oct. 10 plot. So, the suitable planting dates were from Aug. 20 to Aug. 30.The emerging date of 33 bulb plot by the square meter was March 7, but as the planting densities were sparse, the emerging dates delayed by one to three days. The plant height of the 33 bulb plot by the square meter was 21. 8cms, but the other plots were short by
. The number of shoots of the 33 bulb plot by the square meter was 6.1. but the other plots recorded 0.4 increase in the 22 bulb plot, 0.6 increase in the 17 bulb plot and 0.5 increase in the 13 bulb plot compared with that of the 33 bulb plot. Accordingly, the number of shoots in the sparse planting plot was more than that in the dense planting plot. As compared with the 854kgs by the 0.1ha of the 22 bulb plot, the other plots recored 2 percent increase in the 33 bulb plot, 16 percent decrease in the 17 bulb plot and 34 percent decrease in the 13 bulb plot. All things considered, for the culture of Fritillaria thungergii MIQUEL in the middle region, Aug. 25 and 22 bulbs by the square meter were suitable for the planting date and density.

Randomly amplified polymorphic DNA(RAPD) analysis was applied to detect the molecular polymorphisms in Gentiana scabra var. buergeri. A high level of molecular variability was found among wild plants and cultivars. In genetic analysis, eight of twenty primers were selected and 54 amplification products ranged 2. 2 to 0.2 kb were compared. Twenty - nine amplified products showed polymorphic, while five were monomorphic. Twenty of line specific bands were found. In genetic similarity and cluster analysis using PCR products, three wild plants collected from Naejangsan, Daedunsan and Keojedo and one cultivar Seochunjaerae were grouped into one cluster, while cultivar Jinbujaerae and Japanese line separated into another clusters, respectively. The identification of DNA polymorphisms by the RAPD technique will facilitate the selection of the lines from different origin.

This Experiment was conducted to know effect of cutting times and nitrogen split application rates on shoot and root-related characters of Atractylodes japonica. The cutting time was forced on none, once and twice along with three levels of nitrogen split application, all basic 50 -30 -20% and 40 -30 -30%. The plant height declined with increased cutting time and dry matter weight was increased with nitrogen split application under none and once cutting. Average yield of cutted shoot as edible wild plant was 257kg/10a at once cutting condition, but twice cutting condition was little and unfavorable to use edible wild plant because shoot was coarse. Yield 0 dry rhizome was the highest at once shoot cutting under 50 -30 -20% nitrogen split application by 471kg/10a.Especially, culture of Atractylodes japonka needed once shoot cutting one the 10th-30th of May.

Korean Journal of Medicinal Crop Science, volume 4, issue 3, 1996, Pages 255~260
This study was conducted to investigate the characteristics of aboveground plants and red ginseng of polystem ginseng in 6 years of age having two or more stems in a plant. Total leaf weight and area of polystem ginseng were larger, while its stem diameter, and the leaf weight and area of the biggest stem in each plant were decreased with increase the stem numbers in a plant. The ratio of shoot weight to root weight in the polystem ginseng with three or more stems was higher than that in the monostem ginseng and the polystem ginseng with two stems, In ginseng plants with no more than 2 stems, there were positive correlations between root weight and total leaf weight, and leaf area, but not between leaf weight and area of the biggest stem. Inner cavity and inner white, limiting factors for redginseng quality grade, occurred more in tri-stem ginseng than mono- and di-stem one. Percentages of Heaven (1st grade) and Earth (2nd grade) red ginseng in tri-stem ginseng were decreased compared with mono stem and di-stem ginseng.
