  • The field feasibility tests for a phytoextraction process were performed to identify the effect of citric acid as a chelate on the uranium (U) transfer into the plant for the naturally U contaminated soil in Duckpyeongri, Korea. For the feasibility tests, lettuce and Chinese cabbage were cultivated for 49 days on four testing grounds ($1m{\times}1m{\times}0.5m$ in each) in 2016. The citric acid solution was added to two testing grounds (one for lettuce and the other for Chinese cabbage) increasing the U transfer in two crop plants and their results were compared to those without the citric acid solution. When without the citric acid solution, the U concentration of plant after the cultivation was low (< $45{\mu}g/kg$ for leaves and < $450{\mu}g/kg$ for roots). However, with the addition of 50 mM citric acid solution, the U concentration of lettuce leaves and roots increased by 24 times and 1.8 times, and the U concentration of Chinese cabbage leaves and roots increased by 86.7 times and 5.4 times. The absolute accumulated U amount (${\mu}g$) in lettuce and Chinese cabbage also increased by 8.7 times and 50 times, compared to those without citric acid solution. Less than 8% of the U amount of exchangeable/carbonate phases was removed by using the lettuce and Chinese cabbage when the citric acid solution was not applied. However 52% and 66% of the U amount in exchangeable/carbonate phases were removed by the lettuce and the Chinese cabbage when the citric acid solution was added. The effect of the citric acid on the U transfer capability into the plants was quantitatively investigated by the field feasibility test, suggesting that U existing as exchangeable/carbonate phase in soil can be successfully removed by the phytoextraction process using Chinese cabbage with citric acid.

  • Red Chinese cabbage is rich in anthocyanins, with beneficial effects on anti-obesity and lipid profiles. The purpose of this study was to examine the anti-obesity effects of red Chinese cabbage. Four-weeks old Spague-Dawley male rats were divided into four groups for six weeks as follow: Normal Diet (ND), High Fat Diet (HFD), HFD + Red Chinese Cabbage Diet (RCD), HFD + Red Chinese Cabbage Juice (RCJD). After six weeks, the liver weight was significantly higher in the HFD group than in the other groups, and the RCD and RCJD groups showed similar values to the ND group. The epididymal fats were significantly higher in all high fat diets (HFD, RCD, RCJD) than in the ND group and there was statistical significance in the post-tests when comparing the RCD and RCJD groups with the HFD group. Triglycerides significantly decreased in the RCD group. In conclusion, red Chinese cabbage is rich in anthocyanins, with beneficial effects on organ weight and lipid profiles.

  • A cDNA clone for a salicylic acid-induced gene in Chinese cabbage (Brassica rapa subsp. pekinensis) was isolated and characterized. The cabbage gene, designated Br-sil1 (for $\underline{B}$rassica $\underline{r}$apa $\underline{s}$alicylate-$\underline{i}$nduced $\underline{l}$lipase-like 1 gene), encodes a putative lipase that has the family II lipase motif GDSxxDxG around the active site serine. A database search showed that plant genomes have a large number of genes that contain the family II lipase motif. The lipase-like proteins include a myrosinase-associated protein, an anther-specific proline-rich protein APG, a pollen coat protein EXL, and an early nodule-specific protein. The Br-sil1 gene is strongly induced by salicylic acid and a non-host pathogen, Pseudomonas syringae pv. tomato, that elicits a hypersensitive response in Chinese cabbage. Treatment of the cabbage leaves with BTH, methyl jasmonate, or ethephon showed that the Br-sil1 gene expression is induced by BTH, but not by methyl jasmonate or ethylene. This indicates that the cabbage gene is activated via a salicylic acid-dependent signaling pathway. An examination of the tissue-specific expression revealed that the induction of the Br-sil1 gene expression by BTH occurs in leaves and stems, but not in roots and flowers. Without the BTH treatment, however, the Br-sil1 gene is not expressed in any of the tissues that were examined.

  • Changes of sodium chloride content in Chinese cabbage were investigated at different conditions. The diffusion rate of sodium chloride into the cabbage increased with increasing the temperature of brine solution. Sodium chloride content of Chinese cabbage at the lower portion of tank was higher than that at the upper position. The more washing and dewatering, the lower sodium chloride content of the cabbage was found. Microstructure pattern of salted cabbage tissue depended upon height of tank. The changed epidermis cell was recovered after several times of washing.

  • To find out the optimum nitrogen fertilization levels for the leafy vegetables in volcanic ash soils of Cheju island, fertilization effects on chinese cabbage chinese and cabbage were investigated through pot and field experiments. In pot experiment conducted with two volcanic ash soils of Cheju island, optimum rates of nitrogen fertilizer was ranged from 294 to $331kg\;ha^{-1}$ for chinese cabbage. At field experiment with one volcanic soil, the optimum N fertilizer was $331kg\;ha^{-1}$. On the basis of soil organic matters, fertilizer recommendation formula for cabbage, could be established by using 1.03 of comparison factors (F) compared with chinese cabbage : y=344.54-0.285x for chines cabbage, y= 354.88-0.294x for cabbage, where y is the recommendation amount of nitrogen fertilizer with x g $kg^{-1}$ of organic matter in soil. Actual optimum rate of nitrogen fertilizer for chinese cabbage under field condition was much more similar to the value caluculated by the revised nitrogen recommendation formula than the amount of nitrogen fertilizer recommended by the current formula in volcanic ash soil.

  • To develop clubroot resistant Chinese cabbage inbreds, IT 033820, a clubroot resistant turnip, was cross pollinated with a Chinese cabbage inbred of BP 079. From 2005, conventional breeding and microspore culture method performed using these F1 plants as parental materials. In 2007, conventional breeding method resulted in 21 F3 inbreds. After inoculation of clubroot race 4, one inbred showing 83% resistant was selected and registered as 'onkyo 20036ho' in 2008. From 2005, we scanned hybrid cultivars using micro spore culture and developed many doubled haploid (DH) lines in Chinese cabbage. Using Chinese cultivar of 'oong-baek 2ho' we developed 26 DH inbreds in 2007. After inoculation of clubroot race 4, one DH inbred showing 77% resistant and yellow inner leaf color was selected and registered as 'onkyo 20034'in 2008. We found conventional breeding method was effective using introduced germplasm showing low germination. However, when using hybrid cultivar as starting material, microspore culture method was powerful for developing various inbred in short time.

  • Effect of the pretreatment with acetic acid(0.01%, 0.05%, 0.1%) on the fermentation of Chinese cabbage Kimchi, and differences in the degree of maturity between Chinese cabbage blades and midribs were observed. To estimate the degree of maturity, correlation analysis was used with several variables such as pH, titratable acidity, volatile acidity, ascorbic acid content, resazurin test value and pH/acidity ratio. Based on the pH and titratable acidity, the degree of maturity of Chinese cabbage midribs fermented at 10$^{\circ}C$ until the optimum stage of fermentation increased more rapidly than those of the blades. The stage of maturity of Kimchi pretreated with 0.01% acetic acid were slightly prolonged, compared to those pretreated with acetic acid at the higher levels. The pH of Chinese cabbage midribs and blades pretreated with acetic acid was lower than those of control between 2nd and l0th day of fermentation. The volatile acidity of Chinese cabbage midribs and blades increased proportionally with the concentration of acetic acid. The ascorbic acid contents of Chinese cabbage midribs showed higher than those of Chinese cabbage blades. During the fermentation, the higher concentration of acetic acid was used, the less ascorbic acid content was remained. The pH/acidity ratio, volatile acidity, ascorbic acid content and resazurin test value of Chinese cabbage midribs and blades during Kimchi fermentation at 10$^{\circ}C$ showed good correlations with the pH and titratable acidity.

  • Allelopathic chemicals exudated from plants stimulate or inhibit crops directly or indirectly. To prove the effects of allelochemics, we isolated and identified the compounds by bioassays on the monoculture and crosscropping cultre systems. p-Coumaric acid were exudated on all of the test crops such as tomato, red pepper, lettuce, chinese cabbage and sesame, but pyrogallol and phenylacetic acid on tomato. hydroquinone on red pepper and egg plant, pyrogallol on lettuce, and vanillic acid on chinese cabbage. The highest total concentration of allelochemics was $5,883{\mu}g$ on tomato, lowest was $220{\mu}g/g$ dry plant weight on sesame. On the cross-cropping culture of tomato-egg plant, tomato-red pepper, chinese cabbage-egg plant, chinese cabbage-red pepper and chinese cabbage-sasame, the plant height, aerial dry weight and total dry weight of the tomato and the chinese cabbage were inereased contrast with monoculture, but decreased greatly on red pepper and sesame. Growth rate of both crops on the cross-cropping culture of tomato-chinese cabbage declined, while that of chinese cabbage was increased but lettuce decreased on the chinese cabbage-lettuce cross-cropping culture contrast with monoculture.

  • This study was conducted to investigate the quality changes of Chinese cabbage with various storage methods. The V/H ratio, as reference of withering, of Chinese cabbage in PE film was high. Ethanol contents of Chinese cabbage packed with 0.06mm and 0.1mm PE film pouch were greater than that with 0.03mm PE film pouch. Organic acid and sugar contents in the Chinese cabbage were gradually decreased during storage. Chinese cabbage packed with 0.03mm PE film pouch was more adaptable than 0.06mm PE film pouch in winter Chinese cabbage during storage. The CO$_2$ contents in PE film pouch was increased hums 15days of storage, and then not changed during storage. The change of O$_2$ contents in PE film Pouch was opposed to tendency of CO$_2$ change. The 0.06mm and 0.1mm PE film Pouch high CO$_2$ contents and low O$_2$ contents during the storage, were less adaptable than 0.03mm PE film pouch in the winter Chinese cabbage storage.
