全在琪,崔尙台 慶北大學校 産業開發硏究所 1974 硏究報告 Vol.2 No.-

The effects of low temperature treatment (7℃ for 7 weeks) or hot-water then low temperature treatment (45℃ for 60 minutes-7℃ for 7 weeks) on emergence from soil were investigated with completely over-mature and mature bulbs. The obtained results were as follows; 1. The period of mature bulbs from beginning emergence to finishing it was inclined to be effectively shorten by hot-water then low temperature treatment. 2. Hot-water then low temperature treatment was found to be less effective on acceleration in flowering than only low temperature treatment. 3. The over-nature bulbs were found to be more effective on acceleration in flowering by low temperature treatment or hot-water then low temperature treatment than the mature bulbs.

全在琪,徐榮敎,鄭載東 慶北大學校 1982 論文集 Vol.34 No.-

The study was carried out in order to select the best basal medium and to determinate the optimal concentration of auxin added to the basal medium and the most suitable date of inoculation of bulbscales storaged under room or cold temperature. The results obtained were summarized as follows. 1. Bulblet formation percentage and No. of bulblet was the best in LS medium added with 1.0mg/l IBA. 2. Bulblet formation perentage was higher in bulbscales storaged under room temperature, especially 30 weeks storaged bulbs after harvest compared with cold storage. 3. Period of the maximum bulblet formation of Lady Derby was faster than that of Jan Bos, but bulblet formation percentage of the latter was higher than that of the former. 4. Percentage of bulblet formation from bulbscales of Jan Bos storage under room temperature was decreased from harvest time to 12 weeks, that of Lady Derby, to 8weeks, subsequently, followed to be increased, but that from bulbscales of both varieties storaged under cold was inclined to be highly decreased, as storage period from harvest time became longer. 5. Nitrogen content in bulbscale of Jan Bos according to duration of storage was increased from harvest time to 12 weeks, subsequently, followed to be decreased, but that in bulbscale of Lady Derby was continuously increased. Variation of phosphorous content according to storage period was the same tendency in both varities. In room temperature, from 8 weeks, in cold one, from 12 weeks after harvest, it was continuously decreased.

全在璂,鄭載東 慶北大學校 1978 論文集 Vol.25-26 No.-

This experiment was carried out in order to examine the optimum concentration of agar, sucrose, Peptone and Tryptone, for germination and growth, to use the seeds of Dendrobium monile which are originally distributed in Geo-Jae island. These results obtained were summarized as follows. Kyoto solution 1 and Kyoto solution 11 supplemented with 1.0% agar was very excellent for germination. Growth after germination was good in the medium, Kyoto solution 1 added with 0.6% agar, but, when considering germination and late growth, it was thought that 1.0% agar was practically effective. It was clarified as the results of study for improvement of basic medium that adding Peptone 5g/1 or Tryptone 1g/1 to Hyponex 3g/1 highly effected to the growth. By the way, in sucrose concentration, 3.0% sucrose was suitable, especially, dry weight was much increased for other cencentrations.

Ornithogalum의 葉酸에 있어서 子球形成에 關한 硏究

全在琪 慶北大學校 1963 論文集 Vol.7 No.2

In the leaf cuttings of Ornithogalum thyrsoides, the results for the production of bulblets were obtained as follows. 1. In the leaf cuttings of Ornithogalum, the cuttings cur from the basic part of leaf had low production of bulblets, but the average weight as well as the total weight of bulblets was remarkbly high. And the cuttings cut from the middle part of leaf had great numbers of bulblets. 2. According the length of cuttings, the total weight of bulblets was increased. The weight of bulblets, produced by the cuttings taken from the basic part of leaf, is greated than that of them cut from the upper part of leaf among each part devided into three pieces asthe same length. 3. Therefore, it was believed that to get more great weight of bulblets, using the basic part of leaf for cuttings is effective, and to get great numbers of bulblets, using the middle part is effective. 4. In the component of formed bulblets on the different length of cuttings, the amount of reducing sugar was proportioned with that of crude protein. And they were tended to be the same as the average weight of bulblets.

Bryophyllum의 不定芽形成에 關한 硏究 : <第一報> 不定芽形成過程에 있어서 炭水化物加水分解酵素 및 有機成分含有量의 變化에 對해서 the changes in the concentration of carbohydrases and organic components during the process of adventitious bud formation

全在琪 慶北大學校 1964 論文集 Vol.8 No.-

Each adventitious bud arisen from Bryophyllum Daigremontianum and B. tubiflorum which collected on the first of Sept. 1963, was used for materials of this experiment. Some of them were grown in the natural conditions and the others were grown under the lighting for 8 hours to the 17th of Mar. 1964. The later was devided into 3 plots i.e., 8,15 and 24 hours day legnth, so there were four plots in total. and how the lighting hour can effect on the formation of adventitious buds was studied and how the active organic compounds (protein and reducing sugar) and enzyme act on the growing was observed in this experiment. The results obtained were as follows; 1. In the B. Daigremontianum and B. tubiflorum the adventitious buds were not be formed under 8 hours day length, but we found the adventitious buds in the 15 and 24 hours day length and natural condition becoming the long day length. So it was clear that Bryophyllum can be effected by the day length very kindly to form adventitious buds under the condition of long day length. 2. The forming of adventitious buds compared with the other condition was activated under 15 hours day length and the period, from initiation of the projection to the end of adventitious buds forming, was shortened. In the B. tubiflorum the formation of adventitious buds under 15 and 24 hours day length was shown almost similar tendency, however, it was formed more faster than B. Daigremontianum. 3. The Bryophyllum grown in the 8 hours day length was revealed the highest concentration of water and we could observe the relationship between protein and reducing sugar; if the concentraion of protein was low, the concentraion of reducing sugar became high. The concentration of protein was more higher than the other plots in the 8 hours day length plot. 4. Especially noticeable one is the concentration of the reducing sugar and protein. They were once dropped on about the 7th of April and then increased again, and at this time, generally, the enzymes revealed great activity. From the both view-point of the described above and the general tendency, it is considered that at the part where adventitious buds were to be formed, there is already special cell (Notch) which has special property of the forming the adventitious buds. So though there can be some distances in the strength of the avtivity of formation of adventitious buds, ability of the forming the adventitious buds is continued even under the short day length, having no relationship to the day length.

全在琪,徐榮敎,鄭載東 慶北大學校 1979 論文集 Vol.28 No.-

The promoting effects in the previous papers were obtained on the several Cymbidium varieties by treatment of auxin or kinetin alone. The concentrations of auxin and kinetin promoting growth of mericlones and proliferation of protocorms were chosen. Now, auxin or kinetin alone and in combination were applicated in this experiment to examine the effects on growth of Cymbidium and Cymbidium elcapitan. The results obtained were as follows. ① Survival ratio of Cymbidium wakakusa was higher in auxin alone, while that of Cymbidium elcapitan did in auxin and kinetin combined, but plant height of both varieties was retarded in combined medium with auxin and kinetin. ② Rooting was promoted by addition of growth regulators than control plot, especially, 0.5ppm NAA and 15.0ppm IBA showed high rooting ratio by 100%. ③ 1.0ppm IAA promoted plant height, 0.1ppm NAA, root growth, but protocorm proliferation was good at control and 1.5ppm kinetin in Cymbidium wakakusa, while plant height was higher in 15.0ppm IBA, root growth, in 0.5ppm NAA, and protocorm proliferation, 1.0ppm NAA and 15.0ppm IBA+1.5ppm kinetin in Cymbidium elcapitan.

地域別 作物의 適應試驗에 關한 硏究 : 第三報 水稻新品種 維新의 裁培適應試驗 Adaptability of a new rice variety, Yushin in the double cropping paddy fields

全在琪,李愚升,諸商律,洪鐘旭,崔炡 慶北大學校 1977 論文集 Vol.24 No.-

This experiment was conducted to determine the adaptability of Yushin rice variety to Seongju area where rice is mostly planted after barley harvesting. The data obtained in this double cropping paddy fields were compared with those obtained from mono rice culture of various recommended rice varieties which were adopted from the 1976 Annual Report of Gyeongbuk Provincial Office of Rural Development. As compared with mono rice crop, the late transplanting of Yushin as following crop of barley in paddy fields did not delay heading date, showing that Yushin is late transplanting tolerance. At Yeongil, the coastal area of Gyeongbuk province, early transplanting of recommended rice varieties in mono culture did not markedly hasten heading date than that of Yushin in double cropping paddy fields since low temperature during the early growth stage affected crop growth and thus delayed heading to some extent. Yield of mono rice culture except for Yeongil area was much higher than that of Yushin in double cropping paddy fields. Lower yield of Yushin at Seongju and Yeongil was mainly caused by the reduction in filled grain percentage, more severe with Yeongil area. There was a significant negative correlation between heading date and filled grain percentage, showing that grain filling is an important indicator mostly affected by delayed heading. At Seongju, the lower yield of Yushin as compared with Tongil although the higher number of panicle and filled grain percentage were obtained with Yushin might be due to exposure of Yushin crop to contaminated dirty water which comes from the adjoinning villages and due to acute drying at the maturing stage. Thus, it can be concluded that if Yushin were transplanted within the last recommended transplanting date for Tongil lines, Yushin may exert high yielding capability even in double cropping paddy fields.

全在琪,鄭載東 慶北大學校 産業開發硏究所 1977 硏究報告 Vol.5 No.-

This experiment was carried out in order to identify optimum concentration of growth regulators added to Kyoto solution Ⅱ for stimulation of growth of plant height, root length and others, and proliferation of protcorms to use Orchid cultivar "Cym. wakakusa Eburmeq-Robianum." These results obtained were summarized as follows. In the media added with IAA, it was noted that IAA 1.5ppm was the most effective, in NAA, concentration of 0.5ppm was the most suitable, in IBA, 15.0ppm highly stimulated growth, higher concentration of 2,4-D restrained growth, and protocorm became lignification, Kinetin was not suitable for growth of this variety. Judging from the above results indicated, NAA 0.5ppm was identified as the most suitable one for this variety. Especially, it is thought that this medium is effective to proliferation of protocorms as well as growth of mericlones.
