Medicinal plant extracts including Rubus coreanus, Sanguisorba officinalis, Eriobotrya japonica, Prunus mume, Crataegus pinnatifida, Rosa leavaigate Prunus persica, Prunus japonica var. nakaii and Spiraea blumei were prepared for the test of antibacterial activity. Tryptic soy broth (TSB) containing
of medicinal plant extracts was inoculated with
cells/ml of Staphylococcus aureus and incubated at
for 24 hours. The plate counting method and clear zone test were used to test inhibitory effect of the extracts. Minimum inhibitory concentration (MIC) and minimum bactericidal concentration (MBC) was derived from the survival curves of S. aureus. The order of antibacterial activities of medicinal plant extracts on the S. aureus was Rubus coreanus > Sanguisorba officinalis > Eriobotrya japonica > Prunus mume > Crataegus pinnatfida. Minimum inhibitory concentration of Sanguisorba ofEcmalis on the Staphylococcus aureus was 2.5mg/ml and minimum bactericidal concentration of Rubus coreanus was 1.0%. Inhibition zone of Rubus coreanus, Sanguisorba officinalis, Eriobotrya japonica, Prunus mume, and Crataegus pinnatifida was 16.5mm, 14.3mm 11.0mm, 14.0mm and 12.7mm, respectively. The morphology of S. aureus cells treated with medicinal plant extracts showed damage of cell wall and cytoplasmic membrane. Severely damaged cells of S. aureus lost electron dense material and cytoplasm. This result suggests that medicinal plant extracts can be used as an effective natural antibacterial agent in food.

This experiment was conducted to examine the seed structure and to investigate the changes of seed vigor and germinability according to storage condition of Astragalus membranaceus. In case of the hard seed, there observed a gap between a testa and an embryo with abnormal shapes of an hilum and its micropyle. Seeds stored at room temperature maintained vitality for 4 months but continued to lose its vitality, while increase the hand seeds ratio as storing time longer. The content of Ca increased in proportion to the length of storing time.

This experiment was conducted to investigate the effects of temperature, light, seed harvesting time, storage temperature, and period on its germination of Astragalus membranaceus. Optimum germination temperature was
and it was found to be light insensitive seed. The germination rates were not significantly different between 1-year and 2-year old plants, and seed harvesting times. Seeds stored at such cold temperatures as
for 15 months showed over 80% in germination rate at the 6th day after placement. On the other hand, low germination rate of 60% at the 11th day was observed from the seeds stored at
and room temperature.

The contents of chemical components such as total nitrogen, total amino acid, chlorophyll, vitamin C and free sugar were somewhat higher in
gas treatment than those of other treatment. However, the contents of tannin and caffeine did not show any different in the 5 treatments.
acid(GABA) and alanine accumulated in tea leaves under anaerovic condition. The content of GABA acid with
gas treatment was higher 8-6 times with values of
than in control (35mg/100g). The scores of sensory test was not different between anaerobic treatment and control. Consequently, tea mading within
gas treatment after plucking was considered to be the best green tea in terms of functional nature as well as taste nature.

This study was carried out to know the effect of mulching on growth and yield of Peucedanum japonicum. Time from sowing to germination was 8day at raising seedling(RS) and 40day at direct sowing(DS). The order of goodness in top part growth as follows : RS+white vinyl mulching (WVM), RS+black vinyl mulching (BVM), RS+no mulching(NM) and DS+NM. Tap root length at RS + NM was significantly shorter than those at the others. Tap root at the others was about same length. Tap root diameter was significantly larger at vinyl mulching than at no mulching and the thinnest at DS+NM. The number of supporting root at RS was more than DS as much as
. Rate of dried root weight to fresh weight was highest(30.5%) at DS+ NM and low at vinyl mulching. Dried root yield per 10a was 542kg at RS+WVM, 506kg at RS+BVM, 419kg at RS+NM and 357kg at DS. These results suggested that raising seedling and white vinyl mulching was good for culture of Peucedanum japonicum.

Sambaekcho wines were fermented with 5% improved Nuruk, 120% brewing water, and powdered leaf or root as an additive, then the contents of several important phenolics were examined. As the fermentation progressed, the contents of total and flavonoid phenolics, and quercetin-related substances of the Sambaekcho wines increased continuously. The contents of the functional components of the Sambaekcho wines with powdered leaf were much higher than those of the Sambaekcho wines with powdered root, indicating leaf was more adequate than root in making Sambaekcho wine.

This experiment was conducted to evaluate the germination rate according to temperature, pelleting materials, pelleted size, seed storage periods under light and dark conditions in Rehmannia glutinosa. The highest germination rate was obtained from
in both light and dark condition. Two-year old seeds showed higher germination rate compared to one-year old seed. Talc material showed the highest germination rate among the pelleting materials by 82.5%. Among the different pelleting sizes, the highest germination rate was shown in 2.0 mm, and especially Talc pelleting showed 100% germination rate on 17days after seeding. In case of combination of pelleting materials, both of talc + vermiculite, zeolite + vermiculite showed lower germination rate than the control and 0.7 mm pelleted seed showed the highest germination rate.

This study was conducted to provide the basic information on safflower collections and to identify the variations which could be utilized in safflower breeding programs. The agronomic characteristics was used to clarify the genetic relationships among safflower collections and to classify them into distint genetic groups. There were 21 early maturing collections with less than 80 days in number of days from planting to flowering. The number of primary and secondary branches ranged
, respectively, and two collections, IT201434 and IT202723, were found to be high branch types. The 101 safflower collections were classified into 11 groups based on the complete linkage cluster analysis using agronomic characteristics. The I, II, III, IV, IX, X and ? groups included the 25%, 33%, 14%, 8%, 2%, 1% and 1% of the collections, respectively. All the collections in the group III were Korean landraces. The collections in group X could be characterized as early emergence, late flowering and high yield components such as the number of capitula per plant, number of seeds per capitula and seed weight per plant. The number of capitula per plant and seed weight per plant, i.e., the two main yield components, had the highly significant positive correlations with stem diameter, number of the primary branches, number of the secondary branches, number of leaves and leaf length.

The regenerated-bulblets placed in liquid free media resulted in good formation of roots and bulblets. On 1/4 MS free medium, roots and bulblets were predominantly induced. The 1/4 MS liquid medium supplemented with plant growth regulators was the best suitable condition for elongation of leaves and roots. Somatic embryos were frequently developed from embryogenic callus in liquid media with 2,4-D 1mg/ l . On free liquid media, the viability of callus reduced. As the salt strength of MS media reduces, the viability of callus reduced significantly. However, Leaves were induced from several callus clumps. When leaves, roots and bulb-scale segments were placed on MS media containing NAA 1mg/ l or 2,4-D 1mg/ l and various sucrose concentration, the best result about the differentiation, growth of leaf and the differentiation of leaf was obtained on MS media added 1.5% sucrose and 2,4-D 1mg/ l, 3% sucrose and NAA 1mg/ l, and 1.5% sucrose and NAA 1mg/ l, respectively. Also the better result differentiation, growth of root and differentiation of bulb was obtained on MS media with 6% sucrose and NAA 1mg/ l. Spermidine promoted the growth of leaf and the differentiation of bulb. However, spermine promoted the differentiation of leaf, the differentiation and the growth of root in MS solid media. On the MS liquid media, both spermine and spermidine stimulated organogenesis from bulb-scale segments. Regenerated plantlets were acclimatizated and grown in greenhouse in vermiculite + perlite (1 : 1 by volume) well. The optimal soil condition of rooting for plantlets regenerated was in peat moss.
