This experiments were conducted to examine the growth response as resulted by differences of root zone area temperature with varied pots on the Cymbidium kanran and C. virescens during hot season(Jun.∼Sep.). Whereas Root zone temperature in plastic pot by 1.3mm thickness were more sensitive at areal temperature, the range of areal to root zone temperature were changed slowly in clay pot by 6.0 mm thickness. The root zone temperature in 3 kinds pot be tested were changed a little in areal temperature at the 25℃ below, otherwise the higher the areal temperature increased, the more the difference of root zone temperature among 3 kinds pot changed in 3 kinds pot changed. In the growth of Cymbidium virescens cultivated in plastic pot, there was a excessive growth of roots, while the growth of shoots was so poor that sixty percent of seedlings were killed. The growth of roots was reduced in clay pot compare with plastic pot, that showed a good balance between top to root. In this case, the only ten percent of seedlings were killed. The different type among the 3 kinds pot did not show the growth of shoots in Cymbidium kanran, but the growth in clay pot was good relatively. In the growth of roots cultivated in plastic and raxo pot, the number of roots was a little but the length of them was long. In clay pot, there was a large number of roots, but the length of them was short, which had effect on a good T/R ratio.

濟州道의 施設을 理用한 菜蔬類와 球根切花類 및 洋蘭類의 재배실태를 調査한 結果는 다음과 같이 要約할 수 있다. 1. 作目이 토마토와 오이에 編重되어 있어 딸기等을 첨가하여 作目이 多樣化하여야 할 것으로 思料되었다. 2. 施設內의 土壤管理에 대한 認識이 不足하며, 均衡施肥가 施行되지 않고 있었고 土壤酸度도 矯正해야 할 농가가 많았다. 3. Mg이 缺乏된 施設이 대부분이므로 이의 是正이 時急한 課題였다. 4. 施設內 土壤에서 鹽類集積의 被害가 우려되는 곳은 거의 없었으나 裁培年限이 5年以上된 施設에서는 土壤改良이 이뤄저야 할 것으로 思料되었다. 5. 作付體係를 改善해서 年 2期作 體係가 確立되어야 겠으며 施設管利技術이 普及, 育苗技術의 改善 및 共同育苗를 施行해서 健全苗의 養成이 重要課題였다. 6. 濟州道內에서 産業的으로 栽培되고 있는 蘭類 中에서 熱帶産 Cymbidium類가 全體 洋蘭 栽培量의 67.8%로 가장 많았는데 그 中에서도 Eiko, sharnell-5, Kenny가 數的으로 많았다. 7. 溫帶産蘭(東洋蘭)類 中에서는 새우난초類가 數的으로 가장 많았고, 나도풍난, Dendrobrum moniliforme, Cymbidium 風蘭의 順位이었으며, 自生寒蘭은 대 40,396촉이 栽培되고 있었다. 8. 供試 5種의 球根類들은 virus 감염이 甚하여 全量이 virus 無病株로 대체되어야 할 것으로 판단되었다. 9. 서귀포지역의 土壤은 害蟲이 많이 分布하여 球根切花栽培에 큰 위협조건으로 나타났으며 앞으로 도양소독에 대하여 보다 집약적이고 효율적인 方法이 개발되어야 하겠다. 10. 한라산의 고냉지를 利用한 球根의 低溫處理 效果에 對하여 많은 적응시험이 요망되며 道當局은 고냉지의 개발과 利用에 적극적인 지원을 투여하여야 할 것이다. 11. 植栽되고 있는 5種의 球根類 모두 50% 以上이 外國수입에 의존하고 있으므로 國內의 組織培養技術을 利用한 virus 無病良質球根의 生産이 절실히 요망된다. Studies on various cultural practices of vegetable crops, and orchids have been conducted in Chejudo. Followings are the results of such studies. 1. Too much importance has been given to Tomato and Cucumber crops. An additional crop such as Strawberry should be included to broaden the studies. 2. In general, lack of informations on soil managements appear to be prevailing; scheduled fertilization, for instance, has not been performed and pH level must be adjusted on many farm lands. 3. Mg deficiency has been very much in common, therefore, is corection are matter of utmost importance. 4. Problems arising from salt accumulation were nearly unimportant, however, soil improvements through various cultural practices are recommended for those soils which have been continuous cropping for more than 5 years. 5. Planting system should be improved so as to establish 2-crops/year system. In addition, proper extention of various soil management techniques and improvement on nursing techiques are of inportant matters. Commonly sharing community nursing practices must be accompanied in order to provide healthy-seedlings. 6. Among commercially growing orchid species in Chejudo, the tropical Cymbidium species found to be the most widely grown, nearly 67.8% 'Kiko', 'Sharnell-5', 'Kenny' appear to be most in common. 7. Among oriental orchids, Calanthe spp are found to be most prevalent followed in the order of Aerides japonica, Dendrobium moniliforme, Cymbidiums, respectively. 8. The total number of the shoots of Cymbidium kanran being cultivated in Chejudo were found to be 40,396. 9. Virus infections appear to be universal in all 5 species of bulbs studied therefore, virus-free stocks must be essential. 10. Sogwipo-soil, in general, heavily infected by soil-born insects of various kinds are badly affecting bulb productions. More efficient methods of soilsanitations must be studied and introduced in the future. 11. The studies of low temperature treatment on bulb crops by utilizing the high altitude growing in the area of mountain Halla are in great need. An extensive assistance from the provincial government are very much in need in order for the development and utilization of the high-altitude cultivation. 12. More than 50% of the bulbs of the 5 species grown are being imported. Domestic production utilizing 'meristem culture' which enable the virus free stocks are in great demand.

소인섭,강훈 濟州大學校亞熱帶農業硏究所 1996 亞熱帶農業硏究 Vol.13 No.-

SummaryThis experiment was conducted to prevent flower bud blind and inflorescence blasting during the western Cymbidium cultivation in summer. We used 3 kinds of DIF treatments and pots buried directly in soil.Early flowering varieties and medium flowering varieties were affected by DIF treatments. Typically, early flowering varieties flowered 15 days earlier and increased the number of flower stalks and the intensity of flower color.In the treatments of DIF, treatment of 13℃ for 2 hours after sunrise greatly accelerated flowering time, flower initiation and decrease of sort rot disease, compared to treatment after sunset. Late flowering varieties showed no effect on DIF treatments."Buried pot in soil", accelerated flowering, flower initiation and decreased soft-rot disease, but compared to DIF treatment, had only little effect. The soil temperature of the pot buried group was 5℃ higher than the unburied control. Also day and night temperature fluctuated only 1℃. The stability of root-zone temperature played a great role in control of flower initiation and development of the inflorescence.The responses of DIF treatments for different western Cymbidium varieties to DIF treatments were favored in early floweriing varieties. In particular, the DIF treatment and the "buried pot in soil method" seem to retard vegetative growth, compared to the other treatments.

本 硏究는 濟州地域의 冬季 장미 切花裁培를 위한 技術開發의 側面에서 栽培的 品種選拔을 위하여 露地裁培에 대한 可能性을 檢定하며, 土壤과 비배관리를 위한 基礎資料와 組織培養技術을 利用한 優良苗生産技術을 確立하기 위하여 修行하였던바 얻어진 結果는 다음과 같다. 晝夜間의 溫度變化가 심한 環境下에서도 잘適應했던 品種은 'Innocencia'와 'Madelon'이었다. 화경장은 無加溫 비닐하우스가 加溫 유리온실보다 좋았으며, 切花量은 약간 적었지만 濟州道의 西歸浦 地域에서 장미의 冬季 生産을 위한 無加溫 비닐하우스 栽培도 可能한 것으로 나타났다. 加溫과 輔光處理는 開花日數를 10-15일 가량 앞당겼으며 花質과 採花量도 向上시켰지만, 經濟的인 側面에서 볼 때 비닐하우스 無加溫 栽培도 비교적 良好한 結果를 보였다. 共試品種中 無加溫 비닐하우스 輔光栽培에 適合한 轢으로는 'Lorena', 'Dallas', 'Golden Madelion', 그리고 'Carl-red'等 이었다. 장미재배 土壤의 物理性은 孔隙率이 크기 때문에 배수성과 통기성이 장미재배에 적절하였으며, 재배 기간동안 유리온실 토양의 pH, 置換性 Ca, Mg 및 K, 有效燐酸의 함량은 비닐과 露土 토양에 비하여 높게 유지되었다. 不定芽 發生에 대한 基本 배지로는 MS배지 보다 WPM배지가 共試된 品種 모두 월등한 結果를 보였다. 生長點 培養時 0.1-1.0mg/l의 NAA와 2.5-5.0mg/l의 BA 混用處理가 苗의 生産과 生體重 向上에 좋은 結果를 나타냈다. 幼苗의 發根과 根數, 根長 그리고 活着率 모두 1㎖/l IBA處理보다 活性炭 2g/l添加 處理에서 良好하였다. The purpose of this study is to extract useful information for selecting a suitable variety of cultivation for cut flowers of rose. To meet this purpose three different ways of cultivation, such as non-heated and heated cultivations in vinyl house, and outdoor cultivation, were tested in terms of developing cultivation technique for cut flowers of rose during winter period in Cheju island. In addition, the research attempts to obtain basic idea for soil and culture condition and to develop production technique for a superior plantlet by using the technique of tissue culture. After analyzing the results we have reached the following conclusions: 1. 'Inocenia' and 'Madelon' were the most adaptable varieties under the wide temperture changes during day and night. 2. For the flower stem length, the non-heated vinyl house was preferred to the heated glasshouse. 3. It was found that the non-heated vinyl house is possible during winter period in Seogwipo city area. 4. The treatments of heating and supplemental lighting allowed not only to push about 10 to 15 days ahead of the flowering time but also to improve the quality and the amount of flowers. In terms of the economy, however, the treatments of non-heating and supplemental lighting might be preferrable to the one just described. 5. Among the tested cultivars, 'Lorena', 'Madelon', 'Dallas', 'Golden Madelion' and 'Carl-red' were suitable for the cultivation of non-heating and supplemental lighting. 6. Physical properties of the soil in the treatments were suitable for house culture of cut-rose, and pH, available phosphorus, exchangeable Ca, Mg, and K and nitrate concentration of soil in glasshouse were higher than vinylhouse and open field. 7. The results from the test of basic media about the generation of adventitious rooting showed that the WPM medium is better than the MS medium for tested six cultivars. 8. It was identified that the application of 0.1-1.0 mg/l NAA and 2.5-5.0 mg/l BA at the time of meristem culture came out with likable outcomes for plantlet production and improvement of fresh weight. Treatment of 2 g/l activated charcoal is better than 1 mg/l IBA for rooting, root number, root length, and rooting percentage of a plantlet.

김형근,강훈,소인섭 濟州大學校 亞熱帶農業硏究所 1999 亞熱帶農業硏究 Vol.16 No.-

우리나라 자생란인 자란의 기내파종시 적절한 소독방법과 적정배지 및 순화시 생존율을 높이기 위할 목적으로 uniconazole를 처리하고, 풍란과 나도풍란의 기내파종시 발아율을 높이기 위해 천연사과쥬스를 처리한 결과는 다음과 같다. 1. 자란의 기내파종시 종자를 Wilson 용액으로 소독하여 MS 혹은 Hyponex 3g/L 기본배지에 peptone 4g/L 배지에 파종하였을 때 발아와 생장이 가장 좋았다. 2. 기내 파종후 자란의 생장을 억제하기 위하여 uniconazole을 처리한 결과 활성탄 2g/L와 uniconazole 0.01mg/L를 첨가한 처리에서 초장이 넓은 타원형으로 알맞게 억제되었고, 활성탄이 첨가되면 uniconazole 이 활성탄에 흡수되어 억제효과가 다소 적어 활성탄을 첨가하지 않은 처리는 첨가한 처리보다 심하게 억제되었다. 3. 풍란의 기내파종시 Hyponex 3g/L 배지에서는 발아 후 생장이 전혀 이루어 지지 않았고 MS배지에서는 발아만 하였으나, Hyponex 3g/L에 천연 100% 사과쥬스를 첨가한 처리에서는 pH에 관계없이 전처리에서 발아하여 NAA 1mg/L에 활성탄을 첨가한 처리에서 발아와 생장이 가장 좋았다. 4. 나도풍란의 종자 발아와 생육에 대한 배지의 적용성은 풍란의 경우와 유사한 경향을 보여주었다. pH 5.8에 활성탄을 첨가하지 않고 NAA를 1mg/L 첨가한 처리만 발아 후 생장을 하였다. 발아와 생장이 잘된 배지는 Hyponex 3g/L에 천연 사과 주스 100ml/L를 첨가한 처리였으며 PH와 활성탄 및 NAA의 첨가에 관계없이 발아와 생장이 왕성했다. In order to find proper media, accurate sterilizing method and further growth on in vitro-seeding of Bletilla striata, korean native orchid, the uniconazole were treated. And the Neofinetia falcata and Aerides japonicum were treated with natural apple juice to improve germination ratio in vitro-seeding. The results obtained were as follows : 1. Germination and growth of Bletilla striata were the highest in case of seeding to MS or Hyponex 3g/L + peptone 4g/L media after sterilized them by Wilson's solution. 2. The results to promote growth of Bletilla striata after in vitro-seeding were that leaf shape was properly restrained widely ellipse in treated with 2g/L activated charcoal and 0.01mg/L uniconazole, and the treatment of uniconazole was more restrained than the treatment of activated charcoal. 3. In vitro-seeding of Neofinetia falcata, growth after germination was not affected in Hyponex 3g/L media and a little growth is shown in MS media. But in treatment which apple juice 100 ml/L was treated with Hyponex 3g/L, sprouting is shown in every treatments regardless of pH, and the total growth of seedlings is the best in the treatment of activated charcoal 2g/L and NAA 1mg/L. 4. In case of seeding of Aerides japonicum, germination rate and growth were similar trend to Neofinetia falcata. In every treatments of MS media, germination is a little bit, but further growth after germination was shown in treatment which treated NAA 1mg/L and pH 5.8 without activated charcoal. The best germination and growth media for 2 examined seeds were the treatment which apple juice 100 ml/L was treated with Hyponex 3g/L, but there was no effect on pH level, activated charcoal and NAA.

Summary To compare highland with lowland cultivation on growth and flowering response in summer season, 14 species of sub-tropical Cymbidiums were grown in plastic vinyl house. The disease damage by Fusarium and Eriwinia appeared few in "Pieta", "Koihime", "Lullaby", "Lady love", "Alice luna", "Pastel princess" and "Heidi". but much in "Yumechiyo" and "Paul miller". Where they were cultivated in highland, the disease decreased a few. Leaf width had no difference in two place but leaf length shortened by cultivation in highland, and susceptible varieties to shortening trend were "Pieta", "Lady love", "Princess kiko", "Heidi". The number of flower stalk and percentage of commodities were increased in that species of "Rebecca", "Sophia", "Juliet", "Koihime", "Alice luna", "Dee why" and "Yumechiyo". The flowering time on highland cultivation in summer was faster 9 ~ 50 days than on lowland, and the time was accelerated in order of "Juliet", "Pieta". "Princess kiko", "Rebecca" and "Koihime". No efficiency is available the flowering time in late-flowering type Cymbidiums like as "Paul miller" and "Heidi".

생장점배양에서 유래된 소자구의 증식과 비대를 위한 수경재배 매질과 배양액의 효과를 실험한 결과는 다음과 같다. 가. 공시한 3종의 식물에 대한 수경매질의 효과로 볼 때 공시 품종간에 차이는 없었고 생육, 구근증식률과 구근비대에서는 송이+peatmoss처리구에서 가장 좋은 결과를 보였다. 나. 수경액의 종류에 따른 생육, 구근증식률, 및 구근비대에서는 공시 품종간의 차이는 없었고 프리지아의 경우 원더그로 용액이, 구근아이리스의 경우 한국원시액 A가, 그리고 아마릴리스의 경우에는 한국원시액 B가 적합한 결과를 보였다. 다. 구근아이리스의 경우 생육중 부패률이 60% 이상 발생한 결과를 나타내었는데 이는 수경재배 자체의 수분과다가 원인으로 나타나 구근아이리스는 다소 건조상태에서 양구해야할 사항으로 지적된다. This experiment was carried out according to kinds of nutrient solutions and medium for bulb multiplication and enlargement in virus-free bulblet of Freesia. Dutch Iris and Amaryllis obtained by apical meristem culture in vitro. a. The best medium for water culture was soil mixture consisted of one part scoria and one part peatmoss. In this medium, highest ratio of growth and propagation was acquired from the bulblet produced by meristem-tip culture. b. No difference in the bulb growth and the bulblet propagation was obsered between cultivars tested. The best results for bulb growth and bulblet propagation of Freesia, Dutch Iris, and Amaryllis were obtained in Wondergrow, Korean standard nutrient Solution A, and Korean standard nutrient solution B respectively. c. During the nutrient solution cultivation Dutch Iris, over 60% of bulbs decay was observed. Because the over watering may cause the bulb decay, wettable soil condition has to be avoided for the good growth of the Dutch Iris.
