This study was conducted to investigate the possibility of cultivating tea plants planted in the mountain area of west Gyeongnam province, Korea for 2 years from March 27th, 2001 to July 30th 2003. Ninety each plants collected from 5 different sife were cultivated in nursery cup pot
. in the greenhouse condition and transplanted in 5 different location and monitored their survival growing state etc. The results obtained are as follow : 1. Survival rate tea plants after transfer to soil was relatively high Gaya-myeon Hanyang-gun with
and the lowest in Buksang-meyon Geochang-gun with
. The tea plant collected from Gaya-myeon showed the best growing activity at early stage. 2. For the second year of harvesting time, survival rate was the highest in Machun-myeon Hamyang-gun with
and the lowest was Buksang-myeon Geochang-gun with
. 3. For the 3rd year of harvesting time, it was impossible to data collection because of the most upper parts of plants were killed by severe freezing weather condition. In the Baekjeon-myeon, Hamyang-gun Buksang-myeon, Ungyang-myeon Geochang-gun, which are severly cold
in winter season, seems not a suitable places for tea plant cultivation since it is very different to harvest the young loaves in growing season. In conclnsion we could select two sites Gaya-myeon, Hapcheon-gun, Machun-myeon, Hamyang-gun, as tea plant cultivation in the mountain area of west-Gyeongnam province, korea.

This study was carried out to investigate the possibility of double cropping of safflower(Carthamus tinctotious L.) in vinyl house for rainshield culture. Planting methods, i.e., direct seeding as the first crop and direct seeding and transplanting as the second crop, were investigated. Growth characters and establishment were better in the first crop than in the second crop. Between direct seeding and transplanting of the second crop, growth was not significantly different, but establishment was much higher in direct seeding than in transplanting. Seed yield of the second crop was lower
than that of the first crop. In planting methods of the second crop, seed yield was higher in direct seeding than in transplanting. Therefore, optimum method of the second crop for double cropping of safflower in the middle parts of Korea was estimated as direct seeding.

Korean ginseng(Panax ginseng C.A. Meyer) is very difficult to obtain stable production of qualified ginseng roots because of variable stresses in soil environments. In transformation of ginseng with betain aldehyde dehydrogenase gene, compounds synthesized for controlling osmotic pressure such as proline, glycine, betaine, polyols and sugar were accumulated in cell for salt resistance in transgenic plants. 2 Agrobactgerium conjugants were acquired with bet A and bet B genes for solt resistant plants. A. tumefaciens MP90/pBetA and A. tumefaciens MP90/pBetB were recombined for increasing the tolerance to salt stress. To confirm the transformation of the binary vector, tobacco plant was transformed, and the transformant can grow on media containing high concentration of kanamycin. To identify NPT 11, BetA and BetB genes of the transformants, the band on the agarose was confirmed by PCR and RT-PCR techniques. The transformants of ginseng with bet A and bet B genes were acquired on the phytohormone free basic MS media containing only antibiotics and 1M mannitol used for selection of transgenic plant, but the transfomation efficiency for BetA and BetB was very low.

Korean Journal of Plant Resources, volume 18, issue 1, 2005, Pages 22~31
To evaluate growth adaptation of the soybean in paddy field, five soybean cultivars were grown in Yeoncheon with two cultivating methods, level row and high ridge. Growth characters of the top plants, such as stem lengths, numbers of branches, diameters of stem, were higher under high ridge than under level row. However, the differences among the cultivars were bigger than those between the cultivation methods in each cultivar. Comparing the growth of top plants, dry matters in level row were higher than those in high ridge in V5 stage, however, via verses as growth progressed with significant differences among the cultivars. Roots were more developed under high ridge than those under level row during whole growth stages, such as V5, R2, and R5 stages. T/R ratio in level row was significantly higher than that in high ridge with significant differences among the cultivars.

In order to develop the mass production method of anticancer compound-polyacetylene from tissue culture of Panax ginseng C.A. Mayor, these studies were carried out for the effects of various chemicals used as precursor and elicitor in viかo. Ginseng callus cultured on the growth medium containing 5mg/l L-phenylalanine was well grown and detected polyacetylene compounds as well as panaxydol and panxynol. But same media containing
and D.L.-norleucine was not detected any polyacetylene. Panaxydol, one of polyacetylene and active anticancer compound, was detected in calli cultured on media with upper 1mg/l chitosan used as elicitor, but panaxynol was not detected. Nigeran used as active elicitor, caused to decrease the growth of ginseng callus, and don't work as elictor on the biosynthesis of polyacetylene from ginseng callus.

This study was carried out to investigate the utilization of pruned branch of a peach tree as natural dyeing material. The dyestuff was extracted from pruned branch of a peach tree. we examined the dyeing ability on silk and cotton fabrics. The surface color of silk fabrics differed depending on mordants. E values in treatments of mordants ranged from 11.63 to 30.86 as compared to non-treatment. Dyeing properties of cotton fabrics were improved with a treatment of sulfate of iron as compared with of non-treatment. The values a increased when the slaked lime and sodium hydroxide were used as mordants, while the values b increased when copper sulfate, alum and apple vinegar were used. We investigated the surface colors of silk and cotton fabrics after washing three times. In general, the surface colors of silk and cotton fabrics between the treatments of all mordants and non-treatment were diminished by the washing. We also investigated the surface colors of silk and cotton fabrics when those were washed and treated by the light after soaking those into various pH solutions. The surface colors of silk and cotton fabrics were considerably preserved by the washing, the light and pH concentration. In conclusion, our results suggest that the dyestuffs from pruning branch of a peach tree would be useful as a natural dyeing material using the optimized conditions for silk and cotton dyeing.

Charactertistics of growth from graft induced three stock of red pepper cultivar were analysed. R-safe rootstock was more higher and vigorous than that of the Yeok kang, Konesian hot cultivar at seedling stage and had good characteristics for grafting in the space of cut surface and the amount of sap released. Numbers of branches were more numerous in the grafted plants than those of non-grafted as grafting affected their growths in the process of branching. There was no distinct difference in plant height among the different rootstock. However the R-safe rootstock showed considerably high growth in the 41st days after grafting. Grafting was effective in the early flowering and the R-safe was the earliest in flowering because of it's good growth under the low temperature.

High salt concentrations in the ginseng nursery soil environment of Korea is one of important reducing factors for the stable production of quality ginseng. These studies were accomplished for check the response on germination of ginseng seed, somatic embryogenesis of zygotic embryo, and biosynthesis of ginsenoside from ginseng hairy root against NaCl. Ratio of germination was at the
on the basic media with 0.1M and free of NaCl repectedly, but
at the upper of 0.2M NaCl. Somatic embryogenesis from zygotic embryo were the highest when immatured embryo was cultured on free of NaCl concentration, and which was intend to decrease at treatment of NaCl. However, in case of using the matured embryo, treatment of 0.05M NaCl resulted in better embryogenesis than NaCl free media. Red pigment was synthesized from ginseng hairy root cultured on the medium with various NaCl concentration(from 0.04 to 0.08M) and its pigment was analyzed as spectrum of anthocyane by spectrophoto- meter scanning. This cell line biosynthesized lots of crude saponin and total ginsenoside than other cell lines, also had 2 times of panaxadiol than panaxatriol.

With the increase in the level of national income, the interest and demand of the wild edible plants have been increased. Aralia elata Seem is highlighted as a new income source for farmers in Korea. This study was conducted to determine the optimum planting density enhancing the commercial yield and quality in Aralia elata Seem. Yield of new shoots per 10a was increased in the dense planting of
by three years of planting, but it was decreased after four years of planting, which was mainly caused by the factors such as high mortality rate. The income per 10a in the planting density of
(2,000 plants/10a) was higher by
than that in the planting density of
(3,300 plants/10a) which was 968,00won per 10a.

To establish rapid micropropagation through organogenesis from apices-derived callus or direct adventitious shoot of three calla lily cultivars(Zantedeschia spp, cv. Sunlight, cv. Chiante, cv. Pink Persuation) were cultured on Murashige and Skoog medium supplemented with different plant growth regulators. The formation rate of callus, organogenesis and in viかo tuber production among the three cultivars were tested. Callus was obtained from cvs. Sunlight, Chiante and Pink Persuasion; the best cultivar was Sunlight. Sunlight induced
callus and Chiante had the highest rate of
direct shoot regeneration on medium with 2.0 mg/L BA. Regeneration frequencies ranged from 20 to
on medium with 2.0-3.0 mg/L BA. The highest percentage of regeneration and the greatest number of shoots were obtained on medium containing 3.0 mg/L BA in three cultivars. Cytokinins induced multiple shoot formation; 1.0 mg/L of 2ip, 5.0 mg/L of BA, and 1.0 m/L of BA induced 16, 14 and 12 multiple shoots in cvs. Sunlight, Chiante and Pink Persuasion, respectivly. 1.0 mg/L of IAA enhanced root growth in cvs. Sunlight and Chiante while cv. Pink Persuasion exhibited enhanced root growth at 2.0 mg/L of IBA. NAA, however, induced no change in root growth. The addition of 90 g/L sucrose enhanced in vitro tuber formation and following tuber expansion in cv. Sunlight, while 70 g/L of sucrose was effective in cvs. Chiante and Pink Persuasion.

Tuber yield and content of general component and diosgenin which is a main bioactive property were investigated in order to determine the growth characteristics of round typed yam(Dioscorea opposita L.) and the potential of artificial culture at Suwon, Korea. Tubers of round yam were initiated to form at 60 days after planting and then enlargement of tubers lasted by 160 days after planting. Compared to short typed yam(108g), tuber weight of round yam was higher(127g) on the basis of dry weight at 200 days after planting. In comparison of general component between round yam and short yam, protein of round yam
was higher than short yam
. Water content in round yam
was lower in short yam
, indicating a higher dry weight ratio of round yam. Hardness of round yam was 2787.6 while short yam showed about two times higher hardness(4946.9). Lightness was higher in round yam(77.4). In tuber extracts analysis, diosgenin content was respectively
in round yam and
in short yam.

Perilla accessions examined were classified into three maturity groups, i.e, early, medium, and late maturity group of
accessions, respectively. The early and late maturity groups mainly consisted of collections from middle-northern area and southern area, respectively, while the medium group consisted of accessions from all over the country. But chinese Jilim collection wad all mediumgroup. Average 1,000-seed weight(TSW) was 2.7 g. TSW of the collection from Hamyang was the greatest a 3.9g, while the TSW of Pyungchang collection was the smallest as 1.7g, and most of collections produced medium and small seeds. Perilla accessions with greate 1,000-seed weight seemed to be belonged to the late maturity group. Chinese collection was 2.2 to 3.19g and overage was 2.6g in average. Accodingly TSW hadn't more variegation than Korean. Seed coat colors of gorilla accessions were dark brown
and gray brown
, respectively. Among seed coat colors, brown color consisted of
. Chinese was dark brown
in color. Positively correlated that stem height, the number of nodes, branches and flower clusters with Korean and Chinese collection, capsules per flower cluster and the length of flower cluster with Korean collection and 1,000-seed weight and maturing period, flower clusters, stem height and the number of nodes with Chinese collection. And negatively correlated that the number of capsules per flower cluster and 1,000-seed weight with Korean collection and the length of flower cluster, stem height, branches, the number of nodes and flower clusters with Chinese collection.

This study was conducted to clarify the effects of different natural mordants and mordanting methods on the dyeing degree of silk using extracts from Coreopsis drummondii. Surface colors were shown as an order of descent Y in control, and an order of descent Y and YR treated by mordants. Extracts from Coreopsis drummondii was sufficient for the natural dyestuffs.
mordants made from lime-juice of Camellia japonica, oyster shells. and Symplocos chinensis (Lour) Druce for. pilosa (Nakai) Ohwi were used for the dyeing of silk. Surface color of silk was not affected by the concentration of mordants and mordanting methods, however,
mordant was suitable for the dye coloring. It was shown that dye coloring concentrations were highly in the order of mordanting later > mordanting ahead > co-mordanting, and so on. Silks were naturally dyed by the extracts from Coreopsis drummondii, and twenty-nine kinds of natural mordants were treated and screened. Surface color of silk was shown as an order of descent YR treated by the mordants made from the lime-juice of Camellia japonica and Eurya japonica, and as an order of descent Y by the other mordants. By the treatment of natural mordants, concentrations of dye coloring were significantly increased compared with control (none-mordanting), and the potentials as a natural mordant for the effective dye coloring was sufficiently ascertained.

Korean Journal of Plant Resources, volume 18, issue 1, 2005, Pages 198~206
This study was carried out to identify bacterial strains adhered to domestic pet dog hair and to identify antibacterial extracts from natural compounds. A total of 76 strains were isolated from dog hair. The most common species isolated was Staphylococcus spp. (41 isolates), followed by Micrococcus spp. (21 isolates), Enterococcus spp. (8 isolates), Bacillus sup. (3 isolates), Exiguobacterium sup. (2 isolates), Shigella spp. (1 isolate) and Zoogloea spp. (1 isolate). These results suggested that dog hair could be a source of bacterial contamination to human. The susceptibility of isolates to antibiotics and antibacterial activities of the natural compounds were examined by disk diffusion method. Water and ethanol extract from Scutellaria baicalensis revealed high antibacterial activities against Staphylococcus, Micrococcus, Enterococcus and Shigella. Our results suggest that the extract of Scutellaria baicalensis can be used a antibacterial agent against the antibiotic-resistant microorganisms.
