  • This study was inducted to investigate the effects of microbial fertilizers on the fields of young radish(Raphanus sativus L.), chemical components of plant and soil, and the microbial floras. Six microbial fertilizers, MPK+Husk+Palma, Husk+Palma, MPK+Compost, Compost, BIO Livestock Clean System(BLCS) cattle dropping, and Tomi were used. The yields of young radish were increased in six microbial fertilizer treatments. The fresh matter weight, the number of leaves, and the dry matter weight of young radish in BLCS cattle dropping treatment, the leaf length in MPK+Husk+Palma treatment, the sugar content in Husk+Palma treatment, arid the leaf width in Tomi treatment showed the highest amount, respectively. The effects of microbial fertilizers on chemical characteristics of young radish and soil were examined. Phosphoric acid amount of young radish in Tomi treatment was much higher than other treatments. Potassium amount of young radish showed high significance in all microbial fertilizer treatments compared with control, and shoved the highest in Compost treatment . Two components, phosphoric acid find potassium, in soil inoculated by microbial fertilizers showed significant. Phosphoric acid in the Tomi treatment and Potassium in Husk+Palma treatment were increased. The microorganic populations in soil inoculated with microbial fertilizers were examined. While the number of Bacillus in ceil was increased in MPK+Husk+Palma treatment, the numbers of total bacteria, actinomycetes, and fungi were increased in Tomi treatment.

  • 인공산성비(pH 2.7)를 2-3일 간격으로 15회에 걸쳐 1회에 10mm씩 배추와 무의 잎, 토양, 잎과 토양에 처리하여 인공산성비의 처리위치가 가시적 피해증상, 잎의 엽록소 함량, 무기물의 함량, 그리고 수량에 미치는 영향을 검토한 결과는 다음과 같다. 1. 인공산성비를 잎에 처리할 때 배추와 무는 갈색 반점이 다소 발생하였으나 토양에 처리할 때는 피해증상이 없었다. 특히 배추는 결구가 되었을 때는 구의 잎 끝이 갈변하고, 잎에 흑갈색 반점이 발생하였으며, 심하면 잎 전체가 탈색되었다. 2. 인공산성비 처리는 배추 잎의 엽록소 함량을 증가시켰으나 무에서는 차이가 없었다. 3. 배추와 무 모두 N, P, K 함량과 배추의 황 함량은 인공산성비 처리위치간에 차이가 없었다. 그러나 무 잎중 황 함량은 잎이나 토양에 인공산성비를 처리한 것이 황 함량이 높았으며, 뿌리중 황 함량은 토양에 인공산성비를 처리한 것이 잎에 인공산성비를 처리한 것이나 인공산성비를 처리하지 않은 것보다 높았다. 4. 배추의 수량은 인공산성비의 영향을 받지 않았다. 그러나 무는 인공산성비에 의하여 수량이 감소하였는데 특히 잎에 인공산성비를 처리한 것은 뿌리의 수량을 현저히 감소시켰다.

  • Field and nutrient cultures of American ginseng (Panax quinquefolius L.) were used to establish foliar symptoms related to boron (B) concentration in leaves and soils, and to evaluate radish as a time-saving model system for B nutrition. Application of excess B, 8 kg/ha versus the recommended 1.5 kg/ha, to field plantings of 2-, 3-, and 4-yr-old American ginseng plants just prior to crop emergence caused, within 4 wk after crop emergence, leaf symptoms of chlorosis followed by necrosis starting at the tips and progressing along the margins. The B concentration in leaves of 2-4-yr-old plants receiving 1.5 kg/ha Bwas $30{\mu}g/g$ dry mass compared to $460{\mu}g/g$ dry mass where 8 kg/ha B was applied. Similarly, B concentration in soils receiving the lower B concentration was 1.8 mg/g dry mass and $2.2-2.8{\mu}g/g$ dry mass where the higher B concentration was applied. Application of 8 kg/ha B reduced the dry yield of 3rd-yr roots by 20% from 2745 kg/ha to 2196 kg/ha and 4th-yr roots by 26% from 4130 kg/ha to 3071 kg/ha. Ginseng seedlings and radish were grown under greenhouse conditions in nutrient culture with four B concentrations ranging from 0 mg/L to 10 mg/L. At 5 mg/L and 10 mg/L ginseng and radish developed typical leaf B toxicity symptoms similar to those described above for field-grown plants. Increasing B in the nutrient solution from 0.5 mg/L to 10 mg/L decreased, in a linear fashion, the root and leaf dry mass of ginseng, but not radish. Given the many similarities of ginseng and radish to B utilization, radish might be used as a timesaving model system for the study of B, and other micronutrients, in the slow-growing perennial ginseng.

  • This study investigated the effects of image on the preference and intake frequency of 19 vegetables. A total of 359 usable surveys were collected using a convenient sampling method. The subjects included females (51.8%), university students (50.7%), home residents (66.9%) and subject's spending 20,000~40,000 won on meals/week (41.5%) and eat out 2~3 times/week (29.5%). The intake frequency of vegetables was 2~3 times per month. The healthy image of all vegetables was good overall and the average preference was 3.78 (out of 5 on the Likert). Tomatoes had the healthiest image, onions the highest preference, and Korean cabbage the highest intake frequency. For males, the vegetable with the healthiest image was sesame leaf, while the healthiest foods for females were broccoli and tomatoes. Elementary students had a healthier image of cucumber, bean sprouts, radish, sesame leaf, lettuce, radish leaf, and cabbage than university students and adults. Home residents had a healthier image of cabbage and burdock than other types of residents. Subject that st over 20,000 won per week on meals had a higher image of most vegetables. In terms of preference, males liked Korean cabbage, green pumpkin, balloon flower roots, radish leaf, and lotus root, but female liked tomatoes. In addition, elementary students, home residents, and subjects who eat out less often tended to prefer vegetables. In terms of intake, there was a high frequency of intake for all vegetables in adults. Home residents specifically had a higher intake of cucumber, carrot, bean sprouts, spinach, green pumpkin, balloon flower roots, lettuce, radish leaf, broccoli, burdock, lotus root, and tomato. Overall, the healthy image of vegetables had a positive influence on their preference and intake frequency. Therefore, to encourage the intake of vegetables, direct or indirect variables should be examined.

  • 본 실험은 양액의 종류와 배지의 종류, 그리고 양액의 농도가 20일 무의 생육과 몇가지 품질에 미치는 영향을 알아보고자 실시하였다. 20일 무의 양액재배시 적절한 양액의 구명을 위하여 기존의 Cooper, Hoagland, Yamazaki양액의 비교실험을 실시한 결과, YamaBaki양액이 엽장, 엽수, 지상부와 지하부 생체중 등 전반적으로 Hoagland와 Cooper 양액보다 좋은 결과를 나타내었다. 근형지수는 모든 처리구에서 약 0.66으로 비교적 낮은 수치를 보였다. 14가지 조합의 배지를 이용하여 고형배지경을 실시하였다. 그 결과 모래 배지가 가장 균일하고도 좋은 생육의 20일 무를 배출하였고, 피트모스는 반대의 생육을 보였다. 근형지수의 경우 전반적으로 고형배지경이 순수수경재배보다 높은 수치를 나타내었다. Yamazaki 양액의 적정농도 수준을 구명을 위하여 모래를 배지로 하여 20일 무의 생육과 품질을 비교 조사한 결과, 1.0mS/cm 이상의 농도에서는 전반적으로 20일 무의 생육이 좋았으며, 특히 1.5mS/cm가 가장 좋은 생육을 보였다. 비타민 C의 함량과 티오시아네이트 함량은 1.0mS/cm이상의 처리구에서는 현저한 차이가 없었으나, 0.5mS/cm는 상당히 높은 수치를 보였다. 또한 무기물 함량의 경우는 모든 처리구에서 통계적 유의성이 없었으나, 칼륨이 1.5mS/cm에서 비교적 높은 함량을 나타내었다.

  • In the edible parts of chinese cabbage, the NO-3 accumulation was higher in the outer leaves than in the inner leaves and it was higher in the leaf midrib than in the leaf blade. In Radish, it was higher in the aerial part of the root than in the underground part of root. NO-3 accumulation in edible parts of chinese cabbage of organic farming fertilized with compost 8t/10a was about 4 times higher than those of conventional farming with recommended mineral nitrogen; and was similar to those of conventional farming fertilized with twice the mineral nitrogen rate. But, NO-3 accumulation in radish of organic farming with 8t/10a compost was lower than those of conventional farming with recommended mineral nitrogen. It showed NO-3 content in the edible parts of vegetables should be considered one of several parpmeters to judge a real safety vegetable to be certified by government.

  • Purpose: This study was carried out to predict the growth period and fresh weight of sprouts grown in a cultivator designed to grow sprouts under optimal conditions. Methods: The temperature, light intensity, and amount of irrigation were controlled, and images of seed sprouts were acquired to predict the days of growth and weight from pixel counts of leaf area. Broccoli, clover, and radish sprouts were selected, and each sprout was cultivated in a 90-mm-diameter Petri dish under the same cultivating conditions. An image of each sprout was taken every 24 hours from the 4th day, and the whole cultivating period was 6 days, including 3 days in the dark. Images were processed by histogram inspection, binary images, image erosion, image dilation, and the overlay image process. The RGB range and ratio of leaves were adjusted to calculate the pixel counts for leaf area. Results: The correlation coefficients between the pixel count of leaf area and the growth period of sprouts were 0.91, 0.98, and 0.97 for broccoli, clover, and radish, respectively. Further, the correlation coefficients between the pixel count of leaf area and fresh weight were 0.90 for broccoli, 0.87 for clover, and 0.95 for radish. Conclusions: On the basis of these results, we suggest that the simple image acquisition system and processing algorithm can feasibly estimate the growth period and fresh weight of seed sprouts.
