저온처리한 Georgia lily의 촉성재배에 관한 연구
全在琪,崔尙台 慶北大學校 1971 論文集 Vol.15 No.-
Bulbs of the Georgia lily were planted and cooled under natural conditions in a cold frame. Other bulbs were precooled at 4-8℃. These bulbs were transplanted in a vinyl house varying the planting periods. Some of these bulbs were exposed to incandescent lights for experimental purposes. The bloom date, bloom rate, number of flowers, stem length, and number of leaves were recorded to study the effects influenced by the bulb weights and transplanting periods. Plant growth during normal growing season was also recorded. The results were as follows. 1. Naturally cooled Georgia lilies transplanted on Dec. 5 and Dec. 30 were among the first to bloom. Therefore, the Georgia lily may be planted in December, after chrysanthemums and other plants harvesteod from the same vinyl house. 2. The bloom rate and number of flowers increased in large bulbs. Stem lenghts were elongated considerably when the Georgia lily was transplanted earlier and larger bulbs were used. 15g-bulbs transplanted on Dec. 30 were 93.8% in bloom rate with 1.5 flowers and 54.5㎝ in stem lengths. 3. The leaves were more numerous when larger bulbs were planted and not influenced by the transplanting periods. 4. From the above results, it can be determined that 15g-bulbs of Georgia lily showed considerable growth effect when cooled naturally and growth is induced in a vinyl house. Therefore, forcing 15g-bulbs for cultivation is possible. 5. The weight of developed new bulbs was increased when transplanted earlier. 6. Precooling and lighting affected the earlier blooms, and the stem lengths were increased by lighting. 7. Internode was noticeably elongated as soon as the leaves emerged without rosetting of foliage on the precooled Georgia lily.

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.

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.

숙근(宿根)안개초의 조직배양(組織培養)에 있어서 Agar 농도(濃度) 및 Auxins의 농도(濃度)가 Vitrification에 미치는 영향(影響)
전재기,최상태,박인환,신학기 경북대학교 농업과학기술연구소 1988 慶北大農學誌 Vol.6 No.-
숙근(宿根)안개초(草)의 조직배양(組織培養)에 있어 배지(培地)에 첨가하는 agar농도(濃度) 및 auxins의 농도(濃度)가 vitrification에 미치는 영향(影響)을 조사(調査)한 결과(結果)는 다음과 같다. 1. 초장(草長), 생체중(生體重), 분지수(分枝數)는 agar농도(濃度)가 높아질수록 감소(減少)되는 경향(傾向)이었으며 auxins의 효과(效果)는 미약(微弱)하였다. 그러나 초장신장(草長伸長)에 있어서 IAA 1.0ppm+NAA 0.5ppm 및 IAA 2.0ppm+NAA 1.0ppm 첨가구에서는 그 결과(結果)가 매우 양호(良好)하였다. 2. 발근소요일수(發根所要日數)에 있어서는 auxins의 첨가효과(效果)가 적었다. 그러나 근(根)의 생육(生育)에 있어서는 IAA 1.0ppm+NAA 0.5ppm 및 IAA 2.0ppm+NAA 1.0ppm 첨가구에 있어서 분화(分化)된 근(根)의 생장(生長)이 매우 양호(良好)한 경향(傾向)이었다. 3. 건전주율(健全株率)에 있어서는 agar농도(濃度)가 높아질수록 증가(增加)하는 경향(傾向)이었으나 배지(培地)가 너무 경화(硬化)되면(1.5%) 지상부(地上部) 및 지하부(地下部)의 생육(生育)이 극(極)히 저조(低調)하였다. 4. 이상(以上)을 종합(綜合)해 보면 숙근(宿根)안개초의 조직배양시(組織培養時) 외부환경(外部環境)에 대(對)한 적응력(適應力)이 높은 강건한 묘(苗)의 육성(育成)을 위해서는 agar농도(濃度) 1.2%로 한 MS배지(培地)(RM1962)에 IAA 1.0ppm+NAA 0.5ppm 첨가배지(培地)를 사용(使用)하는 것이 바람직하다고 생각된다. The present work deals with the effect of agar and auxins concentrations on vitrification in tissue culture of Gypsophila paniculata L. cv. 'Bristol Fairy' in vitro. The results were summarized as follows. 1. Plant growth, that is, plant height, fresh weight and branching were decreased as increasing agar concentration. On the other hand, addition effect of IAA 1.0mg/l+NAA 0.5mg/l and IAA 2.0mg/l+NAA 1.0mg/l on the plant height were increased strikingly. 2. Addition effect of auxins on the days to rooting were little. And the root development showed same tendency as plant growth. 3. The rate of non-vitrified plants were gradually increased as rising agar concentration. But the addition of agar 1.5g/l in the medium resulted in poor growth. 4. From these results, it was found that following media were the most effective for increasing of non-vitrified and good plant growth in Gypsophila paniculata L. tissue culture.

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.

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.
