The effect of useful rhizobacterium added in bed soil on the early growth promotion of red pepper plug seedlings was investigated. Total 540 colonies of rhizobacteria from 385 samples of eggplant family roots were isolated. Among these, 5 isolates were selected for antifungal activity against pathogenic fungi such as Alternaria solani, Botrytis cinerea, Fusarium oxysporium, Phytophthora capsici, and Sclerotia sclerotiorum. Of all the isolates, MJ-3 having the most pronounced growth-promoting ability for red pepper was finally selected and identified as Bacillus amyloliquefaciens through characterization of biochemical and bacteriological aspects and 16S rDNA sequence. The plant height, stem diameter, root length and fresh weight of red pepper plants which were grown with inoculation of B. amyloliquefaciens MJ-3 were higher than those without inoculation. Especially the root weight of the inoculated red pepper plant increased by 44.3%, the content of endogenous plant hormone (CA$_1$) being 0.556 ng/g (dry weight).

This study was carried out to evaluate the effect of applying levels of Bestamin, animal amino acid, on growth and quality of hot pepper and physicochemical properties of soil. Treatment was given with 200, 400, 800, 1600kg per 10a to control of Bestamin, difference of physicochemical properties was lower than Bestamin, and $P_2O_5$ seems to be reduced, also $K^+$, $Ca^{++}$ were obviously low compared to the control. The content of $NO_{3-}N$ was low compared to control at the Bestamin treated plot. Plant height was longest at 800 treatment and main stem length, main stem weigh and the number of leaves were significantly different with 400 and 800 treatment. No difference was found among the fruit weight, length, diameter in first harvest, but there was significantly different at control of 2nd, 3rd harvest and more increased than 400 and 800 treatment. Fruit weight per plant was the heaviest at 400 and 800 treatment, and the number of fruit was no difference at red pepper but increased with 400 and 800 at green pepper, and yield per 10a was significantly increased to 4503.6kg and 4582.5kg, respectively. Nitrogen in mesophyll accumulation content was obviously reduced at Bestamin treatment compared to control, and amino acid was reduced with control.

This study was conducted to evaluate the effect of phosphorus acid (H₃PO₃) addition to the horticultural bed soil on the initial growth of red pepper (Capsicum annuum L. cv.), cucumber (Cucumis sativus L. cv.), and kimchi cabbage (Brassica campestris L. ssp. pekinensis (Lour.) Rupr. cv.). The stem heights of red pepper and cucumber were 46.1% and 23.0% greater in the 50 mg/L of phosphorus acid treatment than the untreated (control). Further, the stem diameter of pepper and cucumber were 48.7% and 23.0% greater in the 50 mg/L of phosphorus acid treatment than the control. In addition, the number of kimchi cabbage leaves was 47.5% greater in the 50 mg/L of phosphorus acid treatment than the control. The dry weights of red pepper, cucumber and kimchi cabbage were 72.9%, 16.5%, and 30.4% heavier in the 50 mg/L than the control, respectively. Cations (K, Ca, and Mg) and total phosphorus (T - P) were quantitatively analyzed for these three horticultural crops. The concentrations of K, Ca, and Mg, and T - P were higher in the 50 mg/L of phosphorus acid than the control, respectively. Based on the results obtained in this study, it appears that treatment of phosphorus acid in horticultural bed soil enhanced the growth of red pepper, cucumber and Kimchi cabbage.

This study was undertaken to investigate the knowledge and the use of Korea traditional basic side dishes, Jangachies, by housewives. Among the 58 kinds Jangachies, the most well-known Jangachies (above 80% of subjects) turned out to be Perilla leaf, Red pepper leaf, Garlic, Young stem of garlic, Green red leaf, Cucumber and dried Radish Jangachi in the order. In cooking experience of Jangachi, 40% of subjects in Perilla leaf, 28.0% in Green red pepper, 24.8% in Garlic and 24.1% in Red pepper leaf Jangachi have cooked frequently. The proportion of subjests who has bought the marketed Jangachi products were 51.6%. Major problem of that products was pointed out for a sanitary condition, high price and poor taste. If marketed Jangachies were improved over the aspects, the proportion of subjects who would buy the products was 76.2%. The frequency of Jangachi intake was very low on a average due to too salty taste and the difficulty in preparation. The older in age, the more in interest level for Jangachi (p<0.05). 39.6% of subject have had preparation ability of Jangachies. With increasing age (p<0.01), decreasing education level (p<0.01) and those who live in rural area (p<0.05), preparation ability of Jangachi tended to be higher.

This study was conducted to investigate the changes in lipid components of red pepper under various processing conditions such as drying, exposing to lights, extraction and storage conditions. The material used in this study were Chungyang cultivars which contained the largest amount of capsaicinoids and Dabok cultivars which is most popular among the various cultivars produced in Korea. Total lipid content of Chungyang was 15.7% and those of Dabok, Udeungsang and Hongilpum were about 17%. The neutral lipid content in free lipid of red pepper was $78.5{\sim}80.3%$ Phospholipid and glycolipid content in bound lipid were $53.8{\sim}56.9%$ and $35.3{\sim}38.7%$ respectively. The major fatty acids of lipid were linoleic, palmitic and oleic acid. Linoleic acid was presented mainly in pericarp, seed and placenta, whereas the most of palmitic acid was presented in stem. Lipid content of cut and whole red pepper were decreased $24.7{\sim}28%$ and $18.1{\sim}21.5%$ by drying for 48hrs at $65^{\circ}C$ and $95^{\circ}C$. And lipid content was also decreased $3.5{\sim}3.6%$ when the red pepper powder was exposed to 15,000 lux of incandescent light for 30 days at $40^{\circ}C$ and $4{\sim}4.9%$ to fluorescent light. The lipid was extracted the highest content of $50.5{\sim}51.7%$ by acid solution(pH2) and the lowest content by neutral solution, and the higher the salt concentration, the greater the lipid was extracted. During storage at $4^{\circ}C,\;25^{\circ}C,\;40^{\circ}C$, for 30 days the lipid content was not much changed but linoleic acid content was decreased during storage at the same conditions.

Three sludge types from pharmaceutical byproducts and one sludge type from cosmetic waste-water sludge as raw materials of compost were used in a field based concrete pot ($4\;m^2$, $2\;m{\times}2\;m$) for investigating damage of red pepper cultivation. These sludges and pig manure (1 Mg/10a, dry basis) were incorporated into the upper of clay loam soil prior to transplanting with red pepper. Changes in concentration and properties of heavy metal for both of soil and plant were investigated 4 times during of red pepper growth. Plant height and stem diameter of red pepper in sludge treatments except to Pharmaceutical sludge 3 were poor than those of NPK treatment. This result were regarded as an effect of incompleted decomposition sludge which has a lot of organic matter concentration. Amount of total As was increased rapidly Jul. 8. in soil, total Zn Cu Pb Cd were in harvest time, and 1 N-HCl extractable Zn Cu Pb Cd As were in harvest at middle stage and then decreased. Amounts of nitrogen in plant (leaf and stem) were high in Phamaceutical Sludge 1 and fig Manure treatment in early and middle stage because of organic matter and nitrogen concentrations and characteristics. Amounts of Zn, Pb, and Ni in leaf and amount of Zn and Pb in stem were increased in harvest time so that we need to have a concern in detail. Total yield of red pepper was Pig Manure > Phamaceutical Sludge 3 > Phamaceutical Sludge 1 > NPK > Phamaceutical Sludge 2 and Cosmetic Sludge treatment was decreased considerably to compare to others. Amounts of Zn and Cu in green and red pepper in harvest time were higher than the other heavy metals. Finally these results can use to utilize that finding damage on crop for authorization and suitability estimation of raw material of compost.

This study evaluated the influence of light quality and intensity during healing and acclimatization on the $CO_2$ exchange rate, growth, and morphogenesis of grafted pepper (Capsicum annuum L.) transplants, using a system for the continuous measurement of the $CO_2$ exchange rate. C. annuum L. 'Nokkwang' and 'Tantan' were used as scions and rootstocks, respectively. Before grafting, the transplants were grown for four weeks in a growth chamber with artificial light, where the temperature was set at $25/18^{\circ}C$ (light/dark period) and the light period was 14 hours $d^{-1}$. The grafted pepper transplants were then healed and acclimatized under different light quality conditions using fluorescent lamps (control) and red, blue, and red + blue light-emitting diodes (LEDs). All the transplants were irradiated for 12 hours per day, for six days, at a photosynthetic photon flux (PPF) of 50, 100, or 180 ${\mu}mol{\cdot}m^{-2}{\cdot}s^{-1}$. The higher PPF levels increased the $CO_2$ exchange rate during the healing and acclimatization. A smaller increase in the $CO_2$ exchange rates was observed in the transplants under red LEDs. At a PPF of 180 ${\mu}mol{\cdot}m^{-2}{\cdot}s^{-1}$, the $CO_2$ exchange rate of the transplants irradiated with red LEDs was lowest and it was 37% lower than those irradiated with fluorescent lamps. The $CO_2$ exchange rates of transplants irradiated with blue LEDs was the highest and 20% higher than those irradiated under fluorescent lamps. The graft take was not affected by the light quality. The grafted pepper transplants irradiated with red LEDs had a lower SPAD value, leaf dry weight, and dry matter content. The transplants irradiated with blue LEDs had longer shoot length and heavier stem fresh weight than those irradiated with the other treatments. Leaves irradiated with the red LED had the smallest leaf area and showed leaf epinasty. In addition, the palisade and spongy cells of the pepper leaves were dysplastic and exhibited hyperplasia. Grafted pepper transplants treated with red + blue LEDs showed similar growth and morphology to those transplants irradiated with fluorescent lamps. These results suggest that high-quality grafted pepper transplants can be obtained by healing and acclimatization under a combination of blue and red lights at a high PPF level.

The purposes of this study are to investigate perception and preference of Chinese college students for Korean Kimchi by a survey and sensory evaluation and to globalize and industrialize Kimchi in the world. A questionnaire survey was conducted on 588 students residing in Beijing. About 80% of all the participants knew what Kimchi was and 63.4% had eaten Kimchi before the survey . On thier first impression of Kimchi, 43.6% of respondents, answered the nationality of Kimchi is impression after eating Kimchi was 'good'. 51.4% of respondents, answered the nationality of Kimchi is 'Korea'. The most liked Kimchi is Baechu Kimchi, and they preferred the white stem of the Chinese cabbage. On their perception of Kimchi,'Kimchi is a good side dish with cooked rice' was totally received point. The most well-known cooking method of Kimchi turned out to be Kimchi Chigae. As the results of sensory evaluation on several types cabbage Kimchies at room temperature, the most preferred Kimchi by the students was two-day old and made out of 5g red pepper. And two-day old Kimchi lOg red pepper and 2g shangchai added was preferred, too. But the six-day old Kimchi was disliked. The two-day old Kimchi made out of lOg red pepper preserved in the refrigerator was the most-liked. The dishes using Kimchi as the main ingredient are listed according to the students preference as follows Kimchi Hundun, Kimchi Ddungchai, Kimchi Bokum, and Kimchi Ramen, and so on.

An osmotin-like protein (CAOSMl) gene was isolated from pepper leaves infected with the avirulent strain Bv5-4a of Xmthomonas campestris pv. vesicatoria. The cDNA encodes a polypeptide of 250 amino acids with a molecular mass of 27, 361 Da. Its amino acid sequence is highly homologous to various osmotin-like proteins from other plant species. The CAOSMl gene expression was organ- and tissue-specifically regulated In pepper plants. The CAOSMl mRNA was intensely localized in the endodermis area of root tissue and in the phloem cells of vascular bundles of red fruit tissue, but not in leaf, stem, and green fruit tissues of healthy pepper plants. Infection by X. c. pv vesintoria, Colletotrichum coccodes, or Phytopkhora capsici iinduced CAOSMl transcription in the leaf or stem tissues. Expression of the CAOSMl gene was somewhat higher in the incompatible than the compatible interactions of pathogens with pepper. The CAOSMl mRNA was prevalently localized in the phloem cells of the vascular bundle of leaf tissues infected by C. coccodes. The CAOSMl gene was activated in leaf tissues by treatment with ethylene, methyl jasmonate, high salinity, cold acclimation and mechanical wounding, but not by abscisic acid (ABA) and drought. These results indicate that the pepper CAOSMl protein functions in response to Pathogens and some abiotic stresses in pepper plants

Enzyme activity and expression of cytochrome P450 gene involved in the pathway of capsidiol biosynthesis were compared in five different solanaceae plants such as red pepper, green pepper, tobacco, potato and egg plant. Base on genomic DNA and/or RT-PCR results, four solanaceae plants such as red pepper, green pepper, tobacco and egg plant possess P450 gene in the genome and specifically expressed by elicitor treatment. However, potato was appeared to have neither P450 nor cyclase gene in the genome. P450 genes did not show any expression in the plants under normal condition, but showed highly specific expression under elicitation condition in various organs and tissue such as leaf, root, stem and culture cells.
