The study has been conducted to clarify the effects of number of seeds per hill in dibbling on the growth and feed composition of Cheju Local Soybean from May 10 to August 16 in Cheju-Do. The results obtained are summarized as follows ; 1. Plant height when four seeds per hill in dibbling(115cm) was the longest, while one seeds per hill in dibbling(110cm)was the shortest(Y=-0.527X^2+3.885X+107.110). 2. The diameter of stems, number of branches and number of leaves per plant decreased with the number of seeds per hill in dibbling increased. 3. Fresh yield per 10a when four seeds per hill in dibbling(3633kg) were the greatest and three seeds per hill in dibbling, when five seeds per hill in dibbling were intermediate but one seeds per hill in dibbling(2349kg) was the lightest. (Y^*=-125.088X^2+995.387X+1510.790) 4. Dry yield per 10a when four seeds per hill in dibbling(839kg) were the heaviest and when five, six seeds per hill in dibbling were intermediate but one seeds per hill in dibbling(509kg) was the lightest(Y^*=-23.839X^2+221.255X+279.720). 5. Crude protein and crude fat increased with the number of seeds per hill in dibbling increased, but crude fiber and crude ash decreased. 6. There was positive correlation between plant height and fresh yield, and further highly positive correlation between plant height and the diameter of stems, number of branches, number of leaves, or the weight of loaves and negative correlation between plant height and crude protein.

This study was carried out to investigate the influence of irrigation water on agronomic characters and nutrition of soiling corn. Irrigation water was applied at the rate 20, 40, 80, 160, 240kg per pot respertively. The results obtained were summarized as follows: The characters of shoot system (plant length, fresh weight, stem weight, leaf weight, leaf length, number of leaves, stem diameter) was highest at 240kg irrigation water level per pot. The root system (root weight, root length, number of roots) was highest at 160kg irrigation water level per pot. Then decreased at 80, 40 and 20kg level in that order. Tasselling was earlier at 240kg irrigation water level in comparison with the other levels. The concentration of content of nitrogen and potassium was highest at 20kg irrigation water per pot and then decreased 40, 80 and 160kg level in that order. However the content of phosphorus tended to reduce at 40, 80 and 160kg levels in that order. The content of calcium and magnesium was highest at 80kg irrigation water per pot.

조남기 제주대학교 1986 논문집 Vol.23 No.-

This study was conducted to examine the yearly and seasonal changes of Rumex acetoselle in the Permanent pasture of the mountain districts around Mt. Halla in Cheju Island. lor this study. the researcher and investigated for six years the improved pasture which had been used for grazing from 1979 to 1985. The pasture was reclaimed from native grassland. The mixed seeds of 18kg 'Dactylis gomoerata. 7kg' 'Festuca arundinacea, 2kg' 'Lolium multiflorum and 2kg' Trifolium repns 2kg were sowed per 1 ha. The results of this study are the following: The rearly change in the length of Rumex acetoselh its length is radually increased from 27.78cm in the first year after the reclaimation to 38.22cm in the sixth year. this change can be represented by the regression equation, y=0.172x^(2) + 0.697x + 27.309 The rearly change in its density: its density is rapidly increased form 0.43% in the first year to 4.67% in the sixth year. The results of this change can be obtained with the regression equation, y=0.135x^(2)- 0.108x+0.367 The yearly change in the coverage : its coverage is increased year by year from 0.70% in the first year to 6.34% in the sixth year. This change can be calulated with regression equation, y=0.011x²+1.213x-l.014 The yearly change in its weight; the seight is also increased year after after year from 1.02kg in the first year after reclaimation to 25.41kg in the sixth year. This change can be calculated with the regression equation of y=0.1162x^(2)+4.490x-4.838 The seasonal changes of Rumex acetosella its length, density, coverage and weight are heighest in Summer, and are lowest in autumn every year

Rana nigromaculata Hallowell의 發生을 크게 나누어 볼 때 첫째는 卵割과 胚의 發生이며 둘째는 器官의 發生이다. 이들 發生과정에 있어서 形態形成의 관찰결과는 다음과 같다. 1. 야외에서 산란된 卵塊의 卵을 채취하여 發生이 진행되어 가는 단계에 따라 3% Formalin 액으로 고정하고 정지기에서 64細胞의 卵割까지 촬영하였다. 15시간후 桑實胚부터는 硏究室에 가져와 실내수조에서 사육하며, 그 경과를 관찰하였으며 胞胚(24시간후), 낭배(40시간후), 神經胚(80시간후), 尾芽胚(7일후) 등은 발달되어서 幼生으로 되고 卵塊에서 부화(6일후)되기까지 그 순서에 따라 고정하여 形態形成의 과정을 관찰하였다. 2. 器官의 發生, 즉 꼬리와 다리의 發生, 神經系와 감각기의 發生, 입ㆍ인두ㆍ아가미ㆍ허파의 發生, 消化管의 發生ㆍ脊索과 뼈의 發生등은 尾芽胚을 지나 이들의 原基는 결정된 것이다. 다만 形態的으로 볼 때 70일이 경과되면 몸은 비대하고 꼬리의 근원에 뒷다리가 생겨나며, 80일이 지나면 앞다리가 생겨난다. 네 개의 다리가 갖추어지면 꼬리는 급속히 짧아지고 內새는 퇴화되어 허파와 피부로서 공기호흡이 시작하게 될 때 육지로 기어올라온다. 최초의 개구리 몸길이는 1.5cm 정도이고 등에 독특한 반문이 있다. 發生의 속도는 수온에 의해서 좌우되므로 18∼25℃로 사육하면 3개월 정도 되면 개구리가 되었다. 3. 아울러 위의 發生 전과정을 투시표본화에 노력하였으며 이들 제작품은 생물과학 교재로 이용할 수 있으리라 사료된다. If the development of Rana nigromaculata Hallowell is classified in broad terms, first is cleavage and embriotic development, and second is organ development. Observation of the results of these two development processes can be summarized as follows: 1. In the process of development of R. nigromaculata in nature, time of selection was made optionally form the resting period to cleavage into 64 cells and the specimens were arrested in 3% formalin. From the Morula on R. nigromaculata was raised in the laboratory (water temperarure: 18∼25℃) and the following observations in development were made: embryo development after 15 hours, blastula (after 24 hours), gastrula (after 40 hours), neurula (after 80 hours), tail bud germ (after 7 days), organ formation (after 10 days), and external gills (after 20 days). Observation was also made of the morphological development process from the egg mass to hatching (6 days later). 2. In the organ development process, after the tail bud stage (within 10 days), it could be seen that the primitive streak had already been determined. But from a morphological veiwpoint, the hind legs appear at the base of the tail after 70 days, and the front legs appear after 80 days. It was also observed that when formation of the four legs is complete, the tail rapidly shortens, the internal gills degenerate, and breathing through the lungs and skin begins. The initial body length of R. nigromaculata is approximately 1.5cm. and the unique spots on the back appeared. 3. In addition to the optional selection of time for the entire development process above, research has been done in the development of transparent specimens. This research is considered to be helpful in the preparation of such transparent specimens as science materials for biolgy and also for understanding the embriotic development of vertebrates.

This study was to select superior varieties of alfalfa adapted to Jeju environment. Seventeen alfalfa varieties were used in this study. The results obtained are as follows: (1) Weevlcheck, W.L. 303, 153, and Saranaco produced more fresh weight than other varieties and there was no significant difference among them. But Lahontan, Stride, W.L. 525 were light producers in fresh yield. (2) W.L. 303, 530, Saranaco and Narraganset were long but Lahontan, and W.L. 525 are short in plant length and the range were from 4.9 to 53.8㎝. (3) These tendencies on plant length and on fresh weight were similar to those in 1971, and 1972. (4) There were close correlation between plant length and fresh weight(r=0.763 Y=21.06x+539.602). In other word, long varieties in plant length were heavy producers.

趙南棋 제주대학교 1980 논문집 Vol.12 No.-

This study was conducted to investigate the Spring vegetation change on the tame grasslands of Mt. Halla for 7 years from 1971 to 1979. The results are as follows : 1. The dominant species were Dactlis glomerata and Trifolium repens during the first three years, Trifolium repens and Dactylis glomerara in the 4th year, Imperata cylindrical and Trifolium repens during the 5th-6th years, and Imperata cylindrical and Rumex acetoeolla during the 7th-8th years. 2. The mean height of introduced grasses increased progressively for the first three years (45.1-52.4cm) and after that decreased yearly. But that of Weed species increased continuously from the first year (17.5-28.2cm). 3. The coverage of introduced grasses decreased from 86.6% in the first year to 1.1% in the eight year on the pasture. However, that of Weed species increased to 12-98.8%. 4. As the years passed, the coverage of Runmex actosa, Cerastium holosteoides, Imperata cylindrica, Zoysia japonica, Miscanthus sineniss, Pteridium aqvilinum, Erigeron canadensis, Cirsium japonicum, Lespedza cuneata, and Plantago asiatica increased noticeably, but that of Artemisia asiatia decreased.
