우리나라 재래종 벼 197품종과 생태형이 다른 자포니카 7품종, 인디카 3품종 및 통일형 5품종의 벼를 공시하여 각 품종의 이삭 특성을 밝히고 이들 형질간의 상관관계를 검토하였으며 특성에 따른 이삭형태의 분류를 실시하였다. 1. 재래종 벼 품종의 이삭 길이는 22.4 .05㎝, 현미의 천립중은 21.7 .35g로 자포니카와 비교하여 천립중은 같았으나 이삭 길이는 1.6㎝ 더 길었다. 2. 재래종 벼 품종의 1차지경 착생립수와 비율은 67.5 1.9립과 43.7 .14%이었고, 2차지경 착생립수와 비율은 91.2 0.7립과 56.3 .14%이었으며, 총립수는 158.1 5.8립으로 자포니카보다 44립 정도 더 많았다. 3. 재래종 벼 품종 현미의 장폭비는 1.70 .19로 자포니카와 유사하였으며 장립종도 몇 품종 존재하였다. 4. 1차지경 평균착생립수 각 절위별 2차지경수 및 2차지경 평균착생립수에 의한 재래종 벼 품종의 이삭형태를 분류한 결과 2차지경립 착생 하위우세형인 Ⅰ형에 2%, Ⅱ형에 10.7%, 중위우세형인 Ⅲ형에 67.5%, Ⅳ형에 18.3% 및 상위우세형인 Ⅴ형에 1.5%가 분포하였으며, 특히 1차지경 평균착생립수 5.1-5.5개의 Ⅲ형에 가장 많이 분포하였다. 5. 각 형질간의 상관관계에서 총립수와 2차지경 착생립수(0.921), 착립밀도와 평균 2차지경수(0.635)간에는 고도로 유의한 정의 상관이 인정되었다. The traits related to panicle are very important in improving the grain yield in cereals including rice. Characterization of panicle traits was conducted using 197 rice varieties of Korean landrace, 7 cultivars of Japonica, 3 cultivars of Indica and 5 cultivars of Tongil type to classify panicle types by distribution patterns of grains on panicle. In Korean landrace, average length of panicle and 1000-grains' weight of brown rice was 22.4±2.05㎝ and 21.7±2.35 g, respectively. Compare with Japonica. Iandrace was similar in 1000 grains' weight, but with a more longer panicle. Higher number of grains on each panicle (44 grains), was observed in landrace relative to the Japonica of rice. Panicle type was classified into five groups according to the number of grains on the primary rachis-branch, number of grain on the secondary rachis-branch and number of the secondary rachis-branches. According to panicle type based on distribution of grains, landrace was classified into five types. Most of the landrace grouped into panicle type Ⅲ, which is characterized as having many grains on the secondary rachis-branch in the middle position of panicle. Especially, frequency of panicle type Ⅲ which have 5.1-5.5 grains on the primary rachis-branch was higher than any other panicle type. In the case of correlation coefficient among panicle traits, highly positive significant correlations were observed in number of grain per panicle versus number of grains on the secondary rachis-branch(0.921) and in density of grain per unit panicle length versus number of secondary rachis-branch(0.635)

This Research was the standardization of nutrient sources by reviewing the possibility of cultivation and analysis of imported nutrient sources used in Pleurotus ostreatus culture. As a first result, the concentration of heavy metals was not detected or trace, and the total nitrogen content of cotton seed pomace was 6.22% in Australia, which was higher than that of Chinese or USA. As a second result of physical properties of nutrient sources, the water holding capacity of beet pulp from Egypt was higher with increasing pressure. The volume water content of US was highest at 400hpa and 500hpa in case of cottonseed meal. Third, the content of total nitrogen was the highest at pH 5.51 and the total nitrogen content was the highest at 2.45, and the C/N ratio was the highest at 28.18. Last result shows that first germination day, yield and biological effciency of all treatments were not significant differnet except T2. These results shows that australian cootton was inappropriate to Pleurotus ostreatus culture. Nevertheless, the safety and standardization of the Pleurotus ostreatus culture medium should be assured by reviewing the media low material importing season, mushroom yield and nutrient sources.

서산육쪽·코끼리마늘의 흑마늘 숙성 시기별 생리활성 분석

This study analyzed the quality characteristics of black garlic made from Seosan Yukjok Garlic and elephant garlic in Seosan, Chungnam province. Of the inorganic components, Mg content was the highest in all treatment groups, and the Ca content was high in each of the 15 day treatments. The content of K was high after 10 days aging in Yukjok garlic and after 15 days in the elephant garlic. The Fe, Na, K, and Mg content was high in Yukjok black garlic after 15 days, and Na, K, Ca, and Mg were high in the elephant black garlic aged for 15 days. The crude fat content was high in both Yukjok black garlic and elephant black garlic after 15 days. Vitamin C content was highest in both types of garlic after aging for 15 days. An analysis of four kinds of organic acids showed that citric acid was the only organic acid to appear in raw garlic of Yukjok garlic and elephant garlic. Black Yukjok garlic and elephant black garlic had a greater total amino acid content than the raw garlic of either type. However, among the tested amino acids, 13 kinds of amino acids were at their highest after five days of ripening in Yukjok black garlic, while 15 kinds of amino acids were abundant in elephant garlic after the same period. Eight kinds of amino acids were high after aging for 15 days. Through this study, it was confirmed that, in the process of making black garlic, changes in the main components of the garlic occur through different routes, and these changes vary depending on the garlic species. Therefore, this study provided basic data for the processing of Seosan's Yukjok black garlic and elephant black garlic.
