BACKGROUND: Chinese cabbage biosynthesizes various phytochemicals including carotenoids and glucosinolates. Environmental stress has a major effect on the growth and yields of vegetables, and can significantly affect nutritionally important phytochemicals. Phytochemicals of plants are influenced by light, temperature, carbon dioxide, and growing conditions. The aim of this study was to investigate the effect of various light sources on carotenoid and glucosinolate contents in Chinese cabbage. METHODS AND RESULTS: [Experiment I] Set the control (field control, FC) on the ground. Using acrylic sunlight, experiments were set up transparency box (field transparency, FT), red box (field red, FR) and blue box (field blue, FB). [Experiment II] Set the control (chamber control, CC) in the greenhouse. Using plant growth chamber with artificial light, experiments were set up LED red (chamber red, CR), LED blue (chamber blue, CB), LED mixed red+blue (chamber red+blue, CRB) and fluorescent (chamber fluorescent, CF). After plant growth, Chinese cabbage was harvested at 110 days after sowing (DAS). The status of plants growth (leaf length, width, fresh weight etc.) was immediately investigated. Carotenoid and GSL contents were analyzed by HPLC. [Experiment Ⅰ] Results documented that the ranges of total carotenoid contents were 25.39 ~ 58.80 mg/kg dry wt for lutein, 0.84~ 4.22 mg/kg dry wt for zeaxanthin, and 3.85~18.71 mg/kg dry wt for β-carotene. Lutein was the highest for the content and the largest for the variation as well. [Experiment II] Results documented that the ranges of total carotenoid contents were 24.66~137.96 for lutein, 2.51~20.65 for zeaxanthin, and 8.40~49.80 mg/kg dry wt for β-carotene. The total carotenoid contents of CR (156.62) and CB (115.90) were 1.6~2.3 times larger than the other treatments, and β -carotene content was about twice as high as that of the other treatments on the CR (38.74 mg/kg dry wt.). [Experiment I] Total GSL content was the highest in FT (19.76) that was higher 1.7 times than the lowest treatment (11.39 μmol/g dry wt.). [Experiment II] The total content of GSL was highest in CRB (4.19) and lowest in CF (2.88 μmol / g dry wt.). In the CRB, total GSL contents (4.19 μmol/g dry wt.) was the highest. CONCLUSION: Total and individual carotenoid and GSL contents in Chinese cabbage show significant differences under different light sources. Red and blue lights contribute to significant carotenoids expression and antioxidant activity for nutrition and health benefits. These results concluded that the introduction of varying lights affected the synthesis of important nutrient compounds in Chinese cabbage. It is predicted that the application of good light source enhances the accumulation of functional compounds.

BACKGROUND: The present study aimed to examine the crops capable of growing and adapting to the external environment and various stresses of reclaimed agriculture land for the development of high value-added agricultural utilization technology based on reclaimed land through standardization and empirical study of cultivation environment for cultivating crops. METHODS AND RESULTS: Two crops namely turnips and beets were selected for the salt tolerance test of soil environmental conditions on reclaimed land. Turnip and beet seedlings were planted on the soil collected at the 'Seokmun' reclaimed land. There are five treatments such as non-treatment, 1.0, 2.0 (control), 4.0 and 8.0 dS·m <sup>-1</sup> of EC. The contents of betacyanin in beet roots was highest in control and decreased with increasing salt concentration. The GSL contents in the turnip roots waswere highest at EC 2.0 and decreased with increasing salt concentration, whereas those in turnip leaves waswere high both in the non-treated control and atthe EC 1.0-treatment. But, tThere was, however, no statistical differences among the treatments. CONCLUSION: The degree of salt tolerance of crops was examined, and the limit EC iswas expected to be 3.0~4.0 dS· m <sup>-1</sup> as reported to date. If the soil improvement is performed and irrigation systems are used in the actual reclaimed land, the EC of supplied irrigation will be low, and desalination effecttreatment by the lower EC of the supplied irrigation on the soil will lead to more favorable soil condition of the rhizosphere and cultivation environment offor the crops than those in the port experiment. Therefore, monitoring the salinity, water content and ground water level will enable prediction of the rhizosphere environment, and setting up irrigation management and supplying irrigation will lead to crop cultivation results that are close to normal.

인산염을 이용한 Cu 오염토양의 고정화 특성 연구 ( I )
이의상(Lee, Eui-Sang),성호영(Sung, Ho-Young),김지영(Kim, Ji-Young),이주광(Lee, Ju-Goang) 한국산학기술학회 2007 한국산학기술학회 학술대회 Vol.- No.-
인산염을 이용한 구리 고정화 실험의 토양적용가능성을 평가하고자 액상반응실험과 고정화물의 재용출 실험을 수행하였다. 액상반응실험 결과 인산염과 알칼리제 1mole을 넣은 반응에서 99.9%의 구리제 거효율을 보였고 구리의 재용출 농도는 0.64mg/L로 초기농도인 1000mg/L보다 현저히 낮은 값을 나타내었다.

식물은 생장 과정에서 다양한 환경 스트레스에 노출되며, 그 중 광 조건은 식물의 광합성 및 생 장, 이차대사산물 축적에 영향을 미친다. 카로티노이드는 식물체 내 이차대사산물로서과실, 꽃 또 는 식물 뿌리에 주황색, 노란색, 붉은색 등과 같은 색을 부여하고 다양한 향기 성분의 전구체로서 종자 수분과 번식을 돕는다. 또한 카로티노이드는 청색광(400-600 nm)을 흡수하여 엽록소로 전달 하는 식물 생육에 필수적인 광 수확(light harvesting)에 관여한다. 그리고 항산화 기작인 광 보호 기능을 통해 과다한 빛 에너지로 인한 삼중항 상태로 들뜬 엽록소와 단일항 상태의 산소를 소거하 여 활성산소 생성을 방지하고 세포막 손상을 방지한다. 본 실험에서는 배추의 카로티노이드 생합성 과정에 영향을 끼치는 광원(Blue, Red, Blue+Red)을 조사하여 식물체 생장과 체내에 축적된 카 로티노이드 함량을 조사하였다. 배추 종자는 `배추와 육종`에서 제공받았고, 파종 30일 후 유리온 실에 이식하였다. 대조구는 비닐 하우스(CG)이고, 실험구는 Growth Chamber에서 인공광원인 청, 적, 청+적 LED(CB, CR, CBR)와 형광등(CF)을 7일간(2015년 11월 22일∼11월 29일) 처리하였다. 배추는 수확 후 동결건조하고 추출과정을 거쳐 HPLC를 이용하여 카로티노이드를 정량 분석하였다. 배추에서 3가지 카로티노이드 성분(lutein, zeaxanthin, β-carotene)이 분리 되었고, 그 중 사람의 눈에 이로운 lutein이 총 함량의 73.5%를 차지하였고, zeaxanthin이 14.9%, β-carotene 11.6% 를 차지하였다. 총 카로티노이드 함량은 청색(CB) LED에서 360.09 mg/kg dry wt.로 가장 높았으며 이는 대조구(CG)에 비하여 약 1.3배 높았으며, 적색(CR), 청+적색(CBR), 형광등(CF)의 광원 처리한 실험구 모두 대조구에 비해 높은 함량을 나타냈다. 본 실험을 통하여, 인공광원 처리는 배추 내 이차대사산물인 카로티노이드 축적을 증가시키는 것으로 사료된다.
