This studies were conducted to basic information on growth characteristics and root yield in progeny the derived from different bolting years and to establish optimum seed production time in Angelica gigas. Plant height of early and mid-growing stages had decreased with each year increase in bolting year, but showed no significance in late growing stage at different bolting years. Root characteristics including root length, root diameter and dry root weight was slightly good and it had high root/ shoot ratio in third year seed production. respectively. Bolting rate showed that first year seed 38.1%, second year seed 10.4% and third year seed 1.2%, respectively. Therefore, optimum seed production time revealed third year seed for reduce bolting rate. Root yield at different bolting years showed average 1,690kg per hectare as fresh root weight on first year seed, 2,860kg on second year and 2,940kg on third year seed, respectively. A significant positive correlation was appeared between bolting rate and plant height in mid-growing stage. On the other hard, there was highly significant negative correlation between bolting rate and root yield.

This study was carried out to understand the flowering and pollination characteristics in Bupleurum falcatum. Estimated total node numbers of primary branches were 106.6, and the total numbers of florets were theoretically 9,622 until secondary branches flower. In the sizes of floral organs according to the branch order, all of ray, pedicel, petal, pistil, stamen, ovary surface, and sepals have a tendancy to be smaller as this order: main stem> 1st branch> 2nd branch. As the branch development proceeds, the size of florets was getting smaller. Each flowering periods, especially stamen emergence, in different branch positons and in intra-branch were clearly divided. In case of florets, umbellets, and compound umbels enveloped in the gauze and paper, they showed 0% fertilization rate. However, the plants which were entirely enveloped in gauze led to the partial fertilization. Consequently, it was admitted that B. falcatum was a partly allogamous plant, fertilized in the way of entomophily. In respect of pollinatability according to the steps of floral organs maturation, this plant was able to bear fruit after 8 days (Pistil maturation). It was at maturity stages, especially 11 through 13 days, that the maximum fertilization rate appeared.

As a part of studies on the quality control for drying methods in Lycii Fructus. Dried Lycii Fructus were obtained from several treatments to examine the control of the extracts and its physical properties, and also to analyze the inorganic elements and proximate compositions. The results were summerized as follows; the changes of solid matter contents dried at
for 28 hrs were highest. The changes of Hunter values were 66 in lightness, 5.0 in redness and 51.3 in yellowness, respectively in treatment No. 1. And also the viscosity of treatment No. 1. was some high compared to the other treatment. The desirable drying temperature were at
for 2hrs in initial and at
for 24hrs in final temperature and it was the best conditions as a quality, economics and chemical compositions of Lycii Fructus.

Korean Journal of Medicinal Crop Science, volume 4, issue 4, 1996, Pages 288~293
This study was investigated to obtain basic information for the development of irrigation plans in upland cultivation of Wasabi. Changes of stomatal conductivity and photosynthetic rate of Wasabi, and of the soil water potential during withholding watering were analysed. The stomatal conductivity of Wasabi at
light intensity was
, which was about 49% lower than that of Chinese cabbage,
. The temporal changes of light intensity during the daytime did not influence the stomatal conductivity. The soil water potential that decreased stomatal conductivity in Wasabi was about - 50kPa at 10 AM, and about - 30kPa at 3 PM. The photosynthetic rate of Wasabi at
light intensity was
, which was about 50% lower than that of Chinese cabbage,
. The duration required for a stable photosynthetic rate was longer in Wasabi than in Chinese cabbage. The soil water potential that decreased photosynthetic rate in Wasabi was about - 50kPa at 10 AM, and about - 30kPa at 3 PM. The stomatal conductivity and photosynthetic rate showed significant positive correlation at various soil water potential. The results indicated that irrigation in wasabi could be done during the daytime when the soil water potential is above - 30kPa, which does not decrease stomatal conductivity and photosynthesis in Wasabi.

We performed an experiment to confirm the possibility of wasabi culture using the water of the Soyang River Dam in Chunchon and the ground water in Suwon. Water mineral content of Soyang River except for P was less than that of ground water of Suwon. Dissolved oxgen and E C of Chunchon was proper to culture wasabi but E C and dissolved oxgen of Suwon was not suitable for that. Water temp. of Soyang river was very changable by month while that of the ground water in Suwon was kept constantly. In Soyang river of Chunchon the month that water temp. show
, optimal growth temp., was May to Nov. and the month that water temp. show less than
, growth limit temp., was
of Chunchon. Rhizome weight of main stem in Chunchon and Suwon was 63g and 22g per plant and rate of maketable rhizome was each 80%, 0% by culture of 32 months to include raising seedling period of 13 months. Dry matter partitioning ratio of petiole in Soyang river of Chunchon was the highest of all others but it was lowest of all others in ground water of Suwon. Rhizome weight of main stem in Chunchon was showed possitive correlation with plant height and fresh top weight and in Suwon it was showed possitive correlation with root weight and high possitive correlation with No. of total leaves and No. of tillers.

The experiment was conducted to clarify the effect of water stress treatment on growth character of Ligusticum chuanxiong Hort. The water stress treatment was imposed artificially on seedling, flowering and rhizome enlargement stage of the plant. The decrease ratio of leaf area compare with control decreased to 24.4% by water stress treatment at seedling stage and to 41.6% at rhizome enlargement stage. The reduction rate of chlorophyll content at the end of water stress treatment was 41.2% at the seedling stage and no difference at the flowering stage. The chlorophyll content of water stress treatment on seedling and flowering stage was recovered to 95% at harvest time. The ratio of rootlet distribution from top soil to l0cm depth showed maximum to 90% at the seedling stage and to 20cm depth showed maximum to 6.4% at the rhizome enlargement stage. The dry weight of rootlet was decreased to
by water stress treatment. Dry weight of aerial part and underground part of the plant decreased in the order of seedling, flowering, rhizome enlargement and control and the dry weight of aerial part decrease more severely than underground part.

The appropriate drying method in medicinal compounds and color of peony root was that predrying at briquet fire
for 6 hours or more, and then hot air drying at
during 60 hours. But this method needs too much time in drying. And the method that drying at
with hot air drying has bad result in color. In case Peony was seld by cutting product, before cutting, the Peony root was retted for 30 min. and sealed for 12 hrs. is good for drying time, Peoniflorin content and commodity.

Antitumouric effect of loquat was investigated treating the extract from leaves, stems, fruits or seeds to normal and cancer cell lines to check by MTT method wheather the cancer cells are specifially attacked. The results are summarized as follows. Water of MeOH extract from each organ were applied to human normal and cancer cell lines, SNU-1 and SNU-C4. The water extract from fruit flesh gave no dffect to normal cell lines by killed all the cancer cell lines. The water extract from fruit flesh was purified by Sephadex LH-20 and separated into 9 fractions which were than applied to 8 cancer cell lines. The eighth fraction out of the 9 fractions gave no effect to normal cells but exerted specific cytotoxicity to breast cancer, stomach and liver cancer cells. The eighth fraction was orally administed and injected to 10 mice each suffering from the abdominal cancer induced by myeloma cells, SP2/0-Ag14. In the groups received the treatment, only one mouse each died in 2 months but the rest survived until the end of the experimental period, which those in the control plot died in 10 to 13 days. The present results confirmed that loquat contained some substance that had specific cytotoxicity to human cancer cells.

As a first step for improvement of breeding and productivity of Epimedii Herba, the patterns of components and the difference in icariin, a main component of this plant, in compliance with seasons and places of collection were evaluated by HPLC. As a result, the patterns of components in samples collected in July-September were shown to be markedly increased compared to those collected in May. Corresponding to the alternations of the pattern, the amount of icariin, which was estimated to be 0.017% in May was found to be increased markedly up to 0.82% in September. The samples collected at Chul-won district showed the highest icariin contents (0.94%), however, those collected in China was only 50% level (0.4%) of domestic ones. These results strongly suggest that the quality of Epimedii Herba might be quite different with respect to the seasons and places of the collection.

This experiment was carried out to investigate the growth characteristics and root yield with different harvesting times in Astragalus membranaceus. The growth of stem diameter. number of nodes. number of branches and dry weight of top plant were not affected in late harvesting time compare to early harvesting time. but stem height was increased by harvesting time. Otherwise root growth were effected by harvesting time in one and two years old plant. So, root length, weight of dry root and dry root yield were the most excellent until reached up to harvesting of 10th November. The content of methanol extract was not different between one and two years old plant, but that of different harvesting time was the most by harvesting time in mid November. It was suggested that the optimal harvesting time seems to be in mid November rather than in mid or late October.

The root and stem bark of Eleutherococcus spp. is used for the treatment of paralysis, rheumatism, arthritis, diabetes, stamina failure, high blood pressure, etc. This study was conducted to identify botanical origins and to select standard variety of Eleutherococcus spp. with analyzing eleutheroside E content(%) of root bark and that of Eleutherococcus senticosus at different collected area, time, part and grown area. The content of eleutheroside E in the root bark was determined by HPLC, and it was 0.1925% in Eleutherococcus senticosus, 0.1103% in E. chiisanensis, 0.0348% in E. koreanum and 0.0236% in E. sieboldianum. In seasonal change of eleutheroside E content, it was higher in autumn product than summer product in Eleutherococcus senticosus. It also was higher in root bark than stem bark in different part. To investigate eleutheroside E content of root bark among different collected local area in E. senticosus, it was high order to Mt. Deokyu, Hokkaido and Mt. Seolak as a 0.1625%. 0.0493% and 0.027 %, respectively. The growth of Eleutherococcus senticosus was good at grown Unbong (altitude 10m), but eleutheroside E content was high at grown Nogodan (altitude 1, 450m).
