The segregation modes and the selection efficiency of large vascular bundle(LBV) number and panicle characteristics were measured in three hybrid populations of rice. F_1 plants of the three crosses showed different direction and degree of dominance in vascular bundle number and panicle characteristics. The panicle neck diameter(ND), number of primary branches(PB) and LVB showed a typical normal distribution in F_2. When F_2 plants were divided into two groups up culm length of 90cm, the distribution of LVB number and panicle characteristics were not different between two populations. The selected and non-selected F_3 populations showed no difference in distribution of LVB number and panicle characteristics. However, F_3 populations grouped by culm length of 90cm showed different distributions in LVB and 100-grain weight among six characteristics observed. In F_2 populations, ND showed positive correlationship with PB, LVB number and grain number per panicle(GN). ND was positively correlated with PB, LVB number, GN and panicle length in selected and non-selected F_3 populations.

Methods : Balb/c mice were injected intraperitoneally with K-herbal-acupuncture for $LD_{50}$ and acute toxicity test. Sprague-Dawley rats were injected intraperitoneally with K-herbal-acupuncture for subacute toxicity test. K-Herbal-acupuncture was injected on abdomen of mice with S-180 cancer cell line. Result : 1. $LD_{50}$ of K-Herbal-acupuncture was limited $4{\times}10^{-3}$ml/kg~$2{\times}10^{-3}$ml/kg by the test. 2. In acute toxicity test, all of mice were down to the moving reflex, but the weight of mice was increased in treatment group, compared with the normal group. (P<0.05) 3. In acute toxicity test of serum biochemical values of mice, glucose was increased in treatment II group, total cholesterol was increased both treatments.(P<0.05) 4. In subacute toxicity test, the clinical signs of toxication was down to the moving reflex, but it is not severe like acute toxicity test, and observed weight loss at the treatments. 5. In subacute toxicity test, liver weight was decreased compared with the normal group. (P<0.05) 6. In subacute toxicity test of complete blood count test (CBC) of rat, HCT was decreased in treatments, compared with the normal group.(P<0.05) 7. In subacute toxicity test of serum biochemical values of rat, uric acid and triglyceride were decreased, and glucose was increased in treatment groups compared with the control group. (P<0.05) 8. Median survival time was increased about $45\%$ in treatment groups compared with the control group.(P<0.05) 9.

CO₂ 가스화반응에 의해 얻은 호도각 char의 겉보기밀도, 세공반경분포, 세공용적 및 비표면적 등을 추정하여, 가스화방응시 반응온도와 전환율에 따른 char의 세공구조 변화를 조사하였으며, 이론모델(pore volume model, random pore model)과 비교하였다. CO₂ 가스화반응에 의해 형성된 호도각 char는 10Å(micro pore)과 10⁴Å(macro pore) 부근의 세공이 잘 발달된 이원적 구조를 가지고 있었다. 반응 온도가 낮을수록 char의 비표면적과 micro pore 용적은 증가하였으나 macro pore 용적은 변하지 않았으며, random pore model이 가스화반응에 의해 얻은 char의 세공구조값과 비교적 잘 일치하는 것을 알 수 있었다. A char was made from walnut shell which was gasified in CO₂ 7atmosphere and its physical properties such as pore size distribution, density, pore volume and surface area were measured. The effects of reaction temperature and conversion(X_c) on the pore structure change of char were examined and compared with the theoretical values from ihe mathematical modets (pore volume model and random pore model). The char which has bimodal pore distribution near by 10Å (micro pore) and 10⁴Å (macro pore) was obtained by CO₂ gasification reaction. At lower reaction temperatures the surface area (㎡/g-s.m.) and the micro pore volume (㎤/g-s.m.) were increased but the macro pore volume was not affected by the reaction temperatures. It was found that the random pore model was agreed with the pore structure data which were obtained from gasification of the char.

중금속 오염에 대한 Phytoremediation 용 야생식물 연구

김광호,이상각,강병화,심상인,정일민 한국환경농학회 1998 한국환경농학회지 Vol.17 No.4

중금속 오염에 대한 식물복원법(phytoremediation)에 적합한 식물종의 탐색과 확립에 필요한 기초자료를 얻기 위하여 본 연구를 수행하였다. 공시 식물은 단풍잎돼지풀, 갓, 소리쟁이, 어저귀와 같은 야생식물을 이용하였다. 이들 종에 중금속으로 카드뮴과 구리를 처리하여 유묘의 출현과 유묘시기의 생육의 변화 및 양액재배를 통해 중금속이 이들 종에 미치는 영향과 축적되는 정도를 알아보았다. 공시종을 모래에 파종 후 중금속을 토양내 위험 수준으로 처리하고 pH를 6.5, 5.5, 4.5 조절하였을 때 pH가 낮아질수록 출현율 및 유묘의 생육은 저하되었으며 카드뮴에 비해 구리의 피해가 좀더 심하였다. 공시종 중 phy-toremediation에 가장 적합한 종은 단풍잎돼지풀이었으며 이종은 중금속에 의한 유묘의 출현과 초기 생육의 영향이 다른 종에 비해 적었으며, 양액 재배에 있어서도 20μ㏖/L Cd와 80μ㏖/L Cu정도의 농도 처리에 의한 피해 정도가 미약하였다. 미국돼지풀은 중금속 축적량이 유묘의 카드뮴 311㎎/㎏, 구리 369㎎/㎏ 정도가 축적되어 양호한 결과를 나타냈다. The potentials of some Korean wild plants as a phytoremediator for cleaning heavy metal pollution were measured. Several plant species, Ambrosia trifida, Brassica juncea, Rumex crispus, and Abutilon theophrasti screened previously for phytoremediator were treated with cadmium and copper solution. In order to know the growth response to heavy metal stress, the plants were cultivated in hydroponic system containing heavy metals with different concentration. To know the effects of heavy metals on emergence and seedling growth, seeds of 4 species were sown in the pot and watered with heavy metal solution adjusted pH to 6.5, 5.5, and 4.5. A proposed species as potential phytoremediator, A. trifida, showed tolerance to 20μ㏖/L Cd and 80μ㏖/L Cu in nutrient solution without apparent growth reduction, and up to 100μ㏖/L Cd and 400μ㏖/L Cu without critical visual injury. Up to 311㎎/㎏ of Cd and 369㎎/㎏ were accumulated in dried aerial part in A. trifida. In contrast, A. theophrasti showed injury at 400μ㏖/L Cu. Significant differences were shown in Cu accumulation among the four species. A. trifida had much higher concentrations of Cd in the shoot, whereas R, crispus accumulated higher concentrations of Cd in the shoot. Testing plant species showed reduced emergence rate with heavy metal treatment. When pH was lowered, the emergence and seedling growth were affected severely with heavy metal. We can suggested that A. trifida was the most proper species for phytoremediation in heavy metal-polluted regions.

Segregation mode of leaf aroma in F2 and F3 were studied in ten crosses between the three scented rices and five non-scented rice varieties. Three crosses among ten showed the segregation ratio of 1 scented : 3 non-scented plants in F2, two crosses indicated 3 : 13, and four cross fitted to both 1 : 3 and 3 : 13. Segregation ratio of F3 populations of Ilpumbyeo/Hyangmi and Jinbuchalbyeo/Hyangmi indicated that aroma of Hyangmi was not controlled by the single recessive gene, but a few recessive genes. The aroma and heading date in F2 of seven crosses did not segregate independently. The frequency of scented plants was lower in delayed heading plants than that of earlier heading plants.

벼 品種 및 載培法에 따른 쌀가루 Gel Consistency의 變異

金光鎬 建國大學校 附設 農業資源開發硏究所 1992 農資源開發論集 Vol.17 No.-

벼 品種 및 栽培法에 따른 쌀가루 gel consistency의 변이 정도를 밝히기 위하여 국내에서 재배하고 있거나 交配親으로 사용하고 있는 90품종 및 계통을 普通期, 普肥栽培 하였고, 그중 10품종을 골라서 파종기를 4회(4월 24일, 5월 4일, 5월 14일, 5월 24일)로 하고 각 파종기마다 本沓 질소 시비량을 3水準(N-0, 10, 20kg/10a)으로 하여 재배한 후 gel consistency를 비롯한 몇 종류의 米質關聯形質을 조사하였다. 1. 품종간 gel consistency의 변이 정도는 상당히 컸고 供試品種數의 90% 정도가 60∼100㎜의 gel길이를 보여서 soft에 속하였다. 2. 자포니카 품종의 gel 길이 평균치가 통일형 품종의 평균치보다 컸으며 供試한 찰벼 品種의 gel 길이는 모두 최대값인 100mm에 가까웠다. 3. 供試品種간 아밀로스 함량이나 알칼리 붕괴도의 변이 정도는 gel consistency와 비슷하였으며, 품종의 gel consistency와 아밀로스 함량 간 그리고 gel consistency와 알칼리 붕괴도 간에는 負의 相關이 성립되었다. 4. 재배법에 따른 gel consistency의 변이 정도는 품종에 따라서 큰 차이가 났는데, gel 길이가 아주 길거나 아주 짧은 품종은 播種期 및 窒素施用量에 따른 변이가 거의 없었고, 변이를 보인 品種들은 파종기가 늦어지거나 질소 사용량이 많아지면 gel 길이가 짧아졌다. 5. 조사한 米質關聯形質 중 파종기 및 질소 사용량에 따른 변이정도가 가장 큰 것은 쌀알의 心腹白 정도였고 다음이 玄米의 硬度였으며 알칼리 붕괴도는 gel 길이와 마찬가지로 품종에 따라서 재배법에 따른 변이가 큰 경우와 작은 경우가 있었다. 6. 파종기 및 질소 사용량에 따라서 出穗期가 늦어지면 gel 길이는 짧아지는 경향이었고, 이 경우 gel consistency는 알칼리 붕괴도 및 심복백 정도와 負의 相關을 그리고 현미의 硬度와는 正의 상관을 보인 품종이 많았다. Ninety rice cultivars were cultivated with ordinary cultural practices, and ten rice varieties among them were cultivated at three nitrogen levels at each of four different seeding dates. Gel consistency(GC), amylose content(AC), alkali digestibility value(ADV), degree of white-center and white-belly(WCB), grain hardness(GH) and heading date of each plot were observed. Great variation of GC was found between cultivars tested, and most of the cultivars was belonged to soft in GC. Average gel length of thirty seven Japonica type cultivars was longer than that of fourty five. Tongil type rices, and all of five waxy rice varieties showed the maximum value of gel length, 100㎜ or near 100㎜. AC and ADV of the rice cultivars tested also showed varietal variation which was almost same degree with GC. Negeative correlations were found between GC and AC, and between GC and ADV of the cultivars. Degree of variation of GC due to cultural practices was different between cultivars used. Rice varieties, which showed extremely long or short gel length, showed little variation of GC among rice grain samples produced under three different nitrogen levels at each of four different seeding dates. Gel length or rice varieties, which showed significant variation, was decreased by delayed seeding and more nitrogen application. WCB of ten rice varieties tested showed the greatest variation between different cultural practices, and next was GH. Delayed heading caused by late seeding and more nitrogen application decreased gel length. GC showed negative correlationships with ADV and WCB, and positive relationship with GH in this case.

A model development for experimental farm and forest of university was cinducted to enhance the agricultural education of Kon-Kuk University. The results obtained are summarized as follows: 1. It is suggested that the experimental farm of Kon-Kuk University should be located in south-east agricultural area, that is reached around one hour by car from the Seoul campus. However, two or three locations differing environmental conditions for the experimental forest are desirable for the education and research purposes. 2. The experimental farm size should be more than 17 hectares, and low land paddy field should be sized 60 to 70 percentage of the total farm area and the rest be upland field. The area of experimental forest should be larger than 500 hectares to fulfil the current educational situation of Kon Kuk University. 3. Mechanization for crop cultivation should be considerd for planning all kinds of facilities for the experimental farm. 4. Farm management committee has to be organized to review, evaluate and decide everything for the experimental farm management. 5. Experimental farm should be self-supported financially except the budget for regular technicians and assistants salaries. Financial self-support seems to be achieved in 5 to 6 years after new farm opening. 6. It is suggested that cultivation of rice in low land paddy field and growing of ornamental trees and/or forest trees should be major items for cash income of the experimental farm, because these two items are expected to reduce labor and cash input for cultivation. 7. Yearly plan for farm management should consider that around ten percent of total farm land area can be shared for practices and experiments for students and professors. 8. Curriculum and weekly time schedule for the student practices and observations should be rearranged to enhance the efficiency of agricultural education of Kon-Kuk University.
