産地別 Oriental백합 種球의 生育特性 및 切花品質比較
김학기 강릉대학교동해안지역연구소 1999 東海岸硏究 Vol.10 No.1
Oriental 계통 백합의 종구수입 대체의 수출 경쟁력 제고를 위해 국내에서 생산력 구근의 종구로서의 활력을 검토코자 평난지의 고랭지에서 생산된 종구를 화란산과 비교 시험한 결과는 다음과 같다. 1. 강릉, 양구의 고랭지산 종구는 구중이 다소 적지만 화란산 이상이나 버금가는 생육상을 보였으나 남부산은 출아에서부터 개화까지 전반적인 활력이 다수 부진 했다. 2. Casablanca, Marco Polo 양품종 공히 양액재배에서 생육이 촉진되어 초장이 길었으나 화수등 다른 요소에는 차이가 없었다. 3. Casablanca의 경우 국내산 종구는 초장 엽장, 엽폭, 엽수등 모든 요소의 생육이 화란산에 비슷하거나 상회하는 생육을 보였다. 4. Marco Polo에서는 화란산이 양액재배, 토양재배를 막론하고 모든 요소의 생육이 국내산에 비해 우세하였으나 그것은 공시 종구중이 상대적으로 컷기 때문인 것으로 사료된다. 5. 경경(莖徑)은 대체로 0.9∼1.0Cm로 비슷하였고 경도 차이도 산지별, 품종별로 차이를 볼 수 없었다. 6. virus 이병율은 강릉과 양구의 고랭지산이 2~6% 정도로 낮았으나 남부산이 5.5∼15.6%까지 다소 높았으나 이는 화란산보다 오히려 낮은 수치를 보였다. 이상의 결과로 국내 백합 종구는 화란산 종구에 비해 거의 손색이 없으며 특히 고랭지 산이 다소 활력이 높았다. To evaluate potentials for seed bulb import substitution and improvement of export competition of Lilium Oriental Hybrieds, bulbs produced from low and high land (alpine) area in Korea were compared with those from the Netherlands. The results were as following. 1. Qualities of seed bulbs produced from high lands such as Kangnung and Yanggu areas were almost same as those of bulbs from the Netherlands, but bulbs from the south area of Korea seemed to be undesirable from bulb sprouting to flowering. 2. Growth of Casablanca and Marco Polo cultivars in hydroponics was improved to be higher plant height, but there were no differences in flower numbers and other characters. 3. In case of Casablanca, bulbs produced from the domestic area showed more excellent growth in plant height, leaf length and leaf number than bulbs from the Netherlands. 4. In case of Marco Polo, bulbs from the Netherlands in hydroponic and soil culture were better than bulbs from domestic production, but these results seemed to be related with bulbs weight of which was heavier at planting time, compared with bulbs from the domestic. 5. Stem diameter(0.9-1.0cm) in both cultivars and production area was almost the same in both cultivation and production area. Stem hardness showed the same results shown in stem diameter. 6. Virus infection rate of bulbs from Kangnung and Yanggu was 2-6% and that of bulbs from the south area of Korea was 5.5%-18.8%. however these rate was much lower than that of bulbs from the Netherlands. As a results, the bulbs produced from high lands especially such as Kangnung and Yanggu in Korea area were considered to be highly valuable as seed bulbs, compared to bulbs from the Netherlands.

Oriental계 백합의 종구생산에 있어 재배지역 및 정식기가 생육 및 구근비대에 미치는 영향
김학기,이상철,선선영,전승희 강릉대학교 동해안지역연구소 2000 東海岸硏究 Vol.11 No.1
This study was conducted to investigate effects of cultivation area and planting time on bulb growth and enlargement of Lilium oriental hybrids in seed buld production. Planting time was divided into three periods such as May 15, 30, June 15 and Cultivation areas were alpine Daegwallyong and low land Kangnung area. The results were as follows: 1.The temperature of Daegwallyong from June to September was around 16-18℃ which was the optimum temperature for growth of Lilium oriental hybrids compared with above 20℃ of Kangnung area. 2.The bulb emergence rate in Kangnung area was 1-3 days faster than Daegwallyong. As the planting time was delayed, the bulb emergence rate was faster. 3.There was no significant difference in plant height between cultivation area and cultivars, but as the planting time was delayed, the plant height in Kangnung was much longer than Daegwallyong. 4.The chlorophyll content was high in the early planting time and that in Daegwallyong was higher than Kangnung. 5.The fresh and dry weight of leave was increased in Daegwallyong cultivation, compared with Kangnung. 6.The growth of underground parts such as numbers and length of basic roots and root system of stem roots in Daegwallyong was much better than Kangnung. 7.Virus infection rate in Daegwallyong was lower than Kangnung, but in the phytophthora blight and leaf blight vice versa. 8.The faster the planting time was, the higher the bulb weight was. And the bulb weight in Daegwallyong was 93% higher than Kangnung.

揷穗 調製方法 및 몇가지 生長調節物質의 處理가 Phlox paniculata L.의 揷木發根에 미치는 影響
김학기 江陵大學校東海岸地域硏究所 1993 東海岸硏究 Vol.4 No.1
Phlox의 能率的인 揷木發根 方法을 究明하기 위하여 揷穗의 調製에 있어 揷穗의 길이, 굵기, 葉數를 달리한 處理와 Auxin系의 發根促進物質인 IAA, IBA, NAA를 濃度 및 處理時間을 달리하여 實驗한 結果는 다음과 같다. 1. phlox의 莖揷에 있어 揷穗의 길이는 7∼8㎝程度가 發根數, 根長, 發根率 모두에서 有利하였다. 2. 揷穗의 굵기는 3㎜程度가 적당하였고 4㎜이상에서는 能率이 低下되었다. 3. 揷穗의 잔여葉數를 4∼6枚로 調製했을 때 發根率 및 發根力에 差異가 없이 양호한 成績을 보였다. 4. 各種의 Auxin處理區는 無處理區에 비해 能率的인 發根相을 보였으며 그效果는 NAA>IBA>IAA順이었다. 5. phlox의 揷木發根에 能率的인 Auxin物質의 濃度는 IBA 35ppm, NAA와 IAA가 25ppm으로 處理間 顯著한 차이를 보였다. 특히 NAA處理區의 卓效性을 볼 수 있었다. 6. 揷穗의 浸漬時間에 따른 根長의 차이는 미미했으나 根數는 24∼36時間 浸漬處理가 유리하였고 72時間이상 處理에서는 發根率, 根數 등 發根力이 低下되었다. This study was carried out to elucidate the optimum length, diameter, and number of leaves of cuttings and the effective method of auxin substance treatment in the herbaceous cuttings Phlox paniculata L. The results are summarized as follows: 1. The cuttings of 7∼8㎝ in length showed the highest rooting rate and the most favorable growth in relation to root length and number of roots. 2. The most suitable diameter of the cuttings was determined to be about 3mm, and the cuttings over 4mm in diameter showed worse rooting response. 3. When 4∼6 leaves were left on the cuttings, good rooting response was obtained without differences in rooting rate and ability. 4. The cuttings treated with auxin substances rooted better than the control, and the effects were in the order of NAA>IBA>IAA. 5. The most effective concentrations of auxin substances were 35ppm for IBA and 25ppm for both NAA and IAA. 6. Twenty-four to thirty-six hours of dipping in auxin solutions promoted rooting, but the rooting response was worse with the dipping over 72 hours.
