This research was carried out to obtain the field resistance to disease and pest, and high yielding of new Boxthorn (Lycium chinense Mill.) varieties. Growth characteristics, yield potential, correlation of trait which was related the yield and path coefficient of the domestic native varieties. two of cultivated varieties and four of introduced varieties were investigated. In growth characters of collected varieties, the stem length of collected varieties in China were slightly long. Leaf area in Jindo, Kumsan native and Yusong 1 and 2 were wider than that of other varieties. Resistance to pest iniury was very strong at China 1, Japan 1 and Yusong 2 in eriophyidmite, and also resistance to anthrax anthracnose were showed less than 10% of the rate of attack fruit at Japan 1 and China 1. Flowering stage was more early in Chungyang native than that of other varieties. Fruit size of Kumsan native, Yusong 2 were large size fruit varieties. Fruit setting number was most abundant at 1,623 in Yusong 2 which was collected variety. And dry yields of fruit per lOa was more cmparatively abundant in Yusong 2 at 86% than those of Chungyang native. The high correlation cofficienct character with fruit yield were fruit setting and branching number and leaf area. Direct effect by path anaslysis were fruit setting number (Py=0.45), and branching number was showed indirect effect.

An investigation was made to find regional differences and seed characteristics of buckwheats collected from 36 areas in Chungnam province in 1984, and the results obtained are summarized as follows; 1. Grain types of the collected buckwheats were classified as winged, semi-winged and common types. All collections were on the average composed of 50.1 % of common grain types, 26.8 % of semi-winged type and 23.1 % of winged types, respectively. However, there was a great regional difference in components of each grain type among collections. 2. The mean 1000 grain weight was 24.9 gr. The regional differences in 1000 grain weight showed that a collection (collection no. 30) from Susan was 17.4 gr and a collection (collection. no. 16) from Suchon was 31.9 gr. There wasn't any significant relationship between grain types component and 1000 grain weight. 3. Germination of seeds was accelerated as temperature goes up from $5^{\circ}C$ to $30^{\circ}C$. However, interesting germination pattern was observed. That is, seeds from Suchon (collection no. 16), Hongsung (collection no. 23), Cheonweon(collection no. 35), and Yesan (collection no. 27) showed abrupt decrease of germination rate at the temperature of $15^{\circ}C$. The seeds collected from Suchon (collection no. 29), Dangjin (collection no. 32) and from Chungyang (collection no. 21) showed decrease of germination rate at $25^{\circ}C$. These seeds showed, however, the increase of germination percentage at temperature higher than $15^{\circ}C$ and $25^{\circ}C$, respectively. The germination rate for the most collections at $5^{\circ}C$ was less than 10%. However, seeds from Asan (collection no. 33) and Daeduk (collection no. 3) showed 20% and 30% of germination rate at $5^{\circ}C$, respectively. 4. Color of seed coat could be classified into two maj or colors, dark and dark brown. Based on the seed coat color and grain types, all the collections could be classified into the following six categories: winged-black, semi-winged-black, common-black, winged-dark brown, semi-winged dark brown and common-dark brown. The different light absorption rate was found within the UV light zone (190-390 nm) depending upon the two different major seed coat color.

인공지능 기술을 활용하여 동물 소리를 분석하고 그 종을 구별하는 기술은 지역의 야생동물 현황 파악이나 생태계 조사 등에 효과적으로 사용될 수 있다. 인공지능 기술을 활용하기 위해서는 많은 동물 소리 샘플이 필요하지만, 현재 그러한 데이터는 녹음 환경이 고도화되어 있는 상용 DB나 전문가 DB 형태로 존재한다. 이러한 데이터만을 학습한 인공지능의 경우 실제 환경에서 녹음된 동물 소리를 식별하는 데 많은 어려움이 예상된다. 따라서 본 논문에서는 다양한 동물 소리를 수집하기 위해 동물 관련 전문가나 일반 사용자 모두 자유롭게 사용할 수 있는 동물 울음소리 수집과 분류를 위한 오픈 플랫폼을 제안한다. 플랫폼에 업로드된 소리 파일은 인공지능의 학습 데이터로 사용하며, 이 인공지능은 사용자에게 소리 파일을 분석한 결과로 해당 동물종과 그에 대한 다양한 생태정보를 제공하고 부가적으로 지역별 동물 통계 및 소리 파일에서의 소리 구간 추출, 소리 파일 공유 등 다양한 기능을 제공한다.

국내에서 널리 쓰이고 있는 각종 농후사료에 대한 일반성분 및 Ca, P함량을 분석했고 또 비타민, 광물질, 아미노산 함량을 분석하기 위하여 46종의 사료에 대한 대표 시료를 분석했던 바 그 결과는 다음과 같다. 1. 옥수수, 밀, 소맥쇄, 미강(抽), 밀기울, 대두박(抽), 아마박(抽), 옥수수글루텐밀, 임박(抽), 채종박(抽), 호마박(抽), 골분, 어분(국산 및 외산), 패분등이 가장 수집빈도가 높았으며 대개의 경우 일반성분 분석치에 있어서는 미국 또는 일본의 그것과 큰 차이는 없었으나 분석시료 내용이 다른 경우에는 같은 사료라도 변이가 심하였다. 2. 분석치에 있어서 같은 사료라 할지라도 함량변이가 큰 것이 많았는데(말분, 소맥쇄, 맥강미강, 박류, 골분, 어분, 패분등) 이것은 수집된 샘플이 동일하지 않았고, 같은 사료라도 물리적 성상이 다르거나(말분등), 이 물의 혼입등<골분, 어분, 박류등>이 있었기 때문인 듯하다. 3. 선발된 46종 사료의 대표 샘플에 대하여 비타민, 광물질, 아미노산함량을 분석했던 결과를 보고하였으나 이것이 단 1회의 분석이었다는 점, 또는 어떤 성분은 분석이 안되었다는 점을 고려하여 장차의 보완 작업에 기대는 거는 바이다.

This work was conducted to establish an efficient plant regeneration system for genetic transformation and the in vitro conservation of Sedum sarmentosum genetic resources. Effects of glutamine and $AgNO_3$ on plant regeneration between two genotypes were investigated using MS media supplemented with 0.2 mg/L NM and 3.0 mg/L BA. Calluses were formed on leaf explants placed on MS solid media supplemented with 3 mg/L 2,4-D and 1 mg/L BA. Calluses of Keumsan local strain produced shoots at a frequency of up to 100% after 50 days of culture on medium supplemented with glutamine. The highest number of shoots per callus was 17.6 at 350 mg/L glutamine. However, calluses of Wanju local strain gave rise to no shoots under the same culture conditions. Likewise, calluses of Keumsan local strain produced shoots at a frequency of up to 100% after 50 days of culture on medium supplemented with $AgNO_3$ whereas Wanju local strain sporadically produced shoots. The highest number of shoots per callus of Keumsan local stain was 16.1 at $15{\mu}M$ $AgNO_3$. Regenerated shoots were subcultured on hormone-free MS medium for rooting and shoot growth, and then 3-5 cm high plantlets were transplanted to the artificial soils comprising vermiculite and perlite, where they survived at a frequency of 88-100%. After being transplanted into upland soil:sand (1:1, v/v) in a greenhouse, regenerated plants showed a morphologically normal growth.

This study was conducted to classify 80 Artemisia spp. collections based on morphological characters and RAPD analysis to get the basic information of Artemisia spp. collections as medicinal plants. The eighty Artemisia spp. collections were classified into 5 groups with the maximum distance 0.82 between clusters based on the complete linkage cluster analysis with morphological traits. Out of 80 operon primer, 10 primers showing polymorphic bands were selected for RAPD analysis. Among the 98 bands amplified with the primers, 68 (69%) bands showed polymorphism. The number of amplified bands ranged from 8 to 10 with an average number of 9.8 bands. Artemisia spp. collections classified into 6 groups with the similarity value of 0.63 in dendrogram derived from the cluster analysis based on RAPDs. Group consisted of 29 collections. Group, which is the largest one, contained 40 collections. Most of the A. asiatica and A. feddei LEV et VNT. were classified into Group and. The rest of the collections (31%) were classified into Group $III{\sim}V$.
