  • The "Namul" is a Korean common vegetable food composed of edible young leaves and soft stalks of wild plants or cultivating vegetables and treated with traditional condiments. It has been widely used as not only a regular diet but seasonal foods or special ceremonial foods. In this thesis, the kinds of edible plants for namul were philologically approached by books published in Korea from Koryo to Chosun dynasty. The first historical record about cultivated vegetable as food in Korea was a garlic and a gourd in $\ulcorner$Samkuksaki$\lrcorner$. According to numerous records, edible wild plants might have played an important part as food resources, since they have variable edible portions as famine relief foods. Four kinds of namul were first introduced in Koryo age, but in Chosun dynasty over eighty kinds were recorded. The root of ballonflower and white radish were most commonly used for raw namul and bamboo shoot and squash for boils ones. Most kinds of namul were introduced in $\ulcorner$Zeungtosanrimkwungiae$\lrcorner$ and $\ulcorner$Limwonsiprwukji$\lrcorner$ influenced by pragmatism in later half period of Chosun. The chronic state of famine in later half period of Chosun caused to introduce various edible wild vegetables, and had greatly influenced on the Korean people to acquire vegetarian food habits and to favor salty taste. It seems to need a further study on recent nutritional problems including dietary fiber.ary fiber.

  • The NO3 contents and organophosphorus pesticide residues in edible part of vegetables cultivated by a conventional or an organic farming methods were determined. The NO3 contents of vegetables cultivated by the organic farming method were between 120ppm and 4,523ppm, whereas its contents of vegetables cultivated by the conventional farming method were between 89ppm and 1,575ppm. Fifty two percent of vegetables cultivated by hte organic farming method accumulated NO3 content over than 2,000ppm, whereas 82% vegetables cultivated by the conventional farming method accumulated NO3 content below than 1,000ppm. The NO3 contents of lettuce dependent on the cultivation method obviously. The NO3 contents of lettuce cultivated by a hydroponic farming method were between 4,800 and 6,500ppm, whereas those cultivated by the conventional method were between 630 and 750ppm. The organophosphorus pesticide residues in edible part of vegetables cultivated by the conventional or the organic farming methods were not detected. The NO3 contents in edible part of vegetables cultivated by the organic farming method should be considered as one of several parameters to judge a real safe vegetable to be certified by goverment.

  • The objective of the present study was to investigate the protective and free radical scavenging effects of conventionally and organically cultivated kale juices against oxidative damage in $LLC-PK_1$ cells. The DPPH, NO, $O_2{^-}$, and ${\cdot}OH$ radical scavenging activities of organically cultivated kale were higher than those of conventionally cultivated kale juice. Oxidative damage induced by AAPH (2,2'-azobis(2-amidinopropane) dihydrochloride), SNP (sodium nitroprusside), pyrogallol, and SIN-1 (3-morpholinosydnonimine) led to loss of cell viability and increased lipid peroxidation in LLC-PK1 cells, whereas treatment with vegetable juices, especially organically cultivated kale juices, significantly increased cell viability and inhibited lipid peroxidation in a dose-dependent manner (P<0.05). These results suggest that organically cultivated kale juices have protective roles against oxidative stress induced by free radicals.

  • Sixteen seed samples of nine vegetable crops imported from Japan were tested for plant quarantine by routine methods of seed health testing. Nineteen species of fungi including Alternara alternata were identified from the seed samples. Some species were very frequently detected in the seeds. In this experiment, Verticillium albo-atrum, V. dahliae and Macrophomina sp. from the seeds of spinach, and Cercospora capsici, Drechslera hawaiiensis and V. albo-atrum from the seeds of sweet pepper were detected for the first time, respectively. It has been reported that they had a pathogenicity on some vegetable crops in Japan and other countries. The data suggest that an epidemic damage may be occurred if the infected seeds are sown and cultivated in Korea.

  • Vegetables contain high levels of nitrate, which can be converted to nitrite for reaction with secondary amines to form nitrosamines. In this study, we evaluated safety effects against nitrite and nitrosamine as well as anti-mutagenic activities of vegetable juices. To do this, the contents of nitrate, nitrite, and nitrosamines were determined in vegetable juices. The safety effects against nitrite and nitrosamine formation were also investigated under simulated human gastric conditions. The contents of nitrate and nitrite in common and organic kale and Angelica keiskei juices were 931~2,052 mg/kg and 13~82 mg/kg, respectively. However, seven kinds of nitrosamines were not detected in the vegetables juices. The nitrate content decreased when vegetable juices were digested under simulated human gastric conditions. Nitrosamine (N-nitrosodimethylamine) formation under simulated human gastric conditions was inhibited by addition of vegetable juices. In addition, vegetable juices, especially organically cultivated juices, showed anti-mutagenic effects in a Salmonella assay system. These results suggest that organically cultivated vegetable juices are a promising health-promoting source.

  • From the evaluation of physical properties such as springiness, gumminess, adhesiveness, chewiness and hardness by the texture analyzer, vegetable soybean lines with green seed-coat were best as compared with those with black, brown, mixed, and yellow seed-coats. A panel test evaluated on the basis of taste, sweetness, chewiness, and total scores also indicated that soybean lines with green seed-coat were the best. The total scores of panel test was decreased in the order of green > yellow> black> brown seed-coat colored soybean. The mean value of sucrose content obtained by HPLC analysis was highest in black seed-coat colored soybean, and followed by green, yellow, and brown soybeans. The highest sucrose content (8.22%) was observed in 180362, a soybean line with green seed-coat. The full-season type soybeans showed much higher sucrose content than summer types which are mainly cultivated on farmer's fields for vegetable purposes. The final 13 lines selected from 300 colored soybeans showed nearly the same panel scores as Miwongreen. However, these lines had a great deal of variation in sucrose content, and much higher readings in texture analysis than Miwongreen, especially in chewiness and hardness which were the most important properties in vegetable soybeans.

  • The purpose of the study is to investigate factors influencing the adoption of environment-friendly agriculture in greenhouse vegetable production of Jeonnam province. An interview survey were conducted during 2008, including six counties: Gwansanku of Gwangju, Gwangyang, Goheung, Damyang, Boseong, and Suncheon. Major crops grown in surveyed area were green peppers, cucumbers, strawberries, cherry tomatoes, tomatoes, and watermelons. Logit model results show that adopters of environment-friendly agriculture are more likely to participate in extensional education programs, attend educational programs on environment-friendly agriculture, have greater cultivated acreage, and have larger agriculture-only-designated farmland. However the adopters are less likely to have greater number of family members participating in farming, and live Goheung county. Efforts should be made in extensional education programs to lead more vegetable growers to adopt environment-friendly agriculture. Policy makers' additional efforts should be followed to increase adoption rate of environment-friendly agriculture in lower adopted areas.

  • In order to get some basic datas on environmental friendly funtion against soil and water pollution and safe vegetable production by organic farming, chemical characteristics of soils cultivated by the conventional farming, greengouse cultivation and organic farming and acumulation of NO3--N in chinese cabbage and lettuce were analysed. The highest value of NO3--N in 0-30cm subsoil of organic farming was found among the 3 different farming systems, and it was 3.6 and 6.6 times higher than those of conventional farming in chinese cabbage and lettuce respectively. P2O5 also show high accumulation in the rhizosphere of organic farming compared to convnetional farming. The accumulation of NO3--N and P2O5 in the rhizosphere of organic farming were simial to those of greenhouse cultivation. The NO3- accumulation in chinese cabbage and lettuce by organic farming reach 3224ppm in chinese cabbage and 2543ppm in lettuce and it were 4.7 and 6.4 times higher than those of convnetional farming. It is urgently necessary to introduce the basic standard of IFOAM, EU and FAO/WHO Codex on organic agriculture into korean organic agriculture for operation of environmental friendly system and production of safe vegetable in terms of NO3-.
