Soft rot symptom was observed on lily bulb in the fields and at a low temperature storage house from 1999 to 2000 in Korea. The small dark-brown lesion appeared on the bulb, and enlarged and developed into the inner scales of the bulb. The bulb became water soaked and gave out unpleasant odor. Two different pathogenic bacteria were isolated from infected tissues. The causal bacteria were identified as Pectobacterium carotovorum subsp. carotovorum (Erwinia carotovora subsp. carotovora) and Pseudomonas marginalis based on bacteriological characteristics. Pathogenicity of the bacteria was proven by Koch's postulations. This is the first report of bacterial soft rot of lily bulb in Korea caused by the two bacteria.

백합 구근저장고에서 채취한 부패한 구근을 부패 형태별로 구분하여 관여하는 미생물을 동정하고 상처 접종으로 병원성을 조사한 결과 부패 형태는 기저부 갈색 부패, 신초부 갈색 부패, 수침상 부패 및 푸른곰팡이 등 4가지로 구분하였다. 기저부 갈색 부패가 72.5%로 빈도가 가장 높았고, 신초부 갈색 부패가 23%로 빈도가 가장 낮았다. 부패 형태별로 우점균이 달라 기저부 갈색 부패는 Fusarium oxysporum, 푸른색 부패와 신초부 갈색 부패에서는 Penicillium brevicompactum과 P. fellutanum이 우점균 이었다. 몇 가지 살균제를 이용한 백합 구근 소독효과를 조사하였던 바 ???L탄 수화제가 방제가 95.2%로 가장 방제효과가 높았으며, 지오판 수화제, 프로라츠 유제, 지오람 수화제 및 벤레이트티 수화제는 각각 85.6%, 71.8%, 62.5% 및 62.0%였다.

Lily, which is one of Korea's main flower exports, is one of the most important agricultural product in the country. Korean lily farmers have difficulty earning more profit from producing lilies, because of the high cost of lily bulbs. Most lily bulbs used in Korea are imported from the Netherlands. Thus, the Korean government has kept trying to supply more and better Korean lily bulbs. However, many experts have questioned the efficiency and economic value of the Korean lily production system. The purpose of this paper is to analyze the economic value of the production of lily bulbs in Korea. Especially, this study evaluates the economic value of the production systems of Korean lily bulbs and compares the results from several cases. The results of the present study presents some useful findings, as follows: first, two Korean production areas (Gangneung and Jeju) show a positive economic value but one Korean production area (Taean) presents problems causing a negative economic value. Second, the Korean production area in Vietnam currently has trouble in the view of economic value but will likely overcome that problem. Third, the production area in the Netherlands shows the best economic value. Thus, Korean lily bulb producers need to benchmark that system.

This study was conducted to improve and supplement the system of cryopreservation for adventitious bulbs induced by tissue cultured bulb-scales of lily (Lilium spp.) cvs. 'Milky way'. The explants, bulblets and bulb-scale-bulblets, were treated to low temperature (4℃) for 7 days prior to the pre-culture. The adventitious bulbs were pre-cultured in Murashige and Skoog (MS) liquid medium supplemented with sucrose (0.3 and 0.7M). The pre-cultured adventitious bulbs were treated to loading solution (LS1 or LS2, C4 or C6) containing 35% of PVS3 (LS1, C4) or 40% of PVS3 (LS2, C6) for 40 min and exposed to dehydration solution (PVS3, B1) containing 50% glycerol and 50% sucrose for 60 min at 25℃. The adventitious bulbs were moved onto droplets containing 3 µl PVS3 on sterilized aluminum foils, and then soaked into liquid nitrogen (LN) for 60 min. The result of highest regrowth rate as 65.7% was obtained in cold treatment (4℃), osmoprotected with LS1 solution, and cultured in PCM3 medium by using bulb-scale-bulblet for cryopreservation. This result shows that droplet-vitrification could be used as a promising method for long-term storage of lily genetic resource.

The adventitious bulbs were moved onto droplets containing 3 ㎕ PVS3 on sterilized aluminum foils, and then soaked into liquid nitrogen (LN) for 60 min.

Plants regenerated from in vitro cultures are associated with chromosomal variations, which have been generally found in long-term culture. Reducing plant culture age is one of the ways to reduce genetic and epigenetic changes. The present study focused on the efficient in vitro propagation of lily cultivars and has intensified to speed up bulb propagation for cryopreservation. The multiplication process applied in this experiment uses starting material, which the newly small bulb formed from bulb-scales in two lily cultivars. The adventitious bulb from bulb-scale tissue cultured on three different media following Murashige and Skoog (MS) basal medium supplemented with 1 g/L Charcoal, MS medium containing 0.3 mg/L IAA and 0.4 mg/L BA hormone with or without Charcoal, respectively. After about seven weeks, there is little change in the number of newly propagated bulbs in small bulbs of the two media. Compared to the both mediums, the number of the propagated bulbs is increased 5 times in MS medium containing 0.3 mg/L IAA and 0.4 mg/L BA hormone without Charcoal. After about seven weeks, the results of the propagation showed that the number of the propagated bulbs is increased 5 times in MS medium containing 0.3 mg/L IAA and 0.4 mg/L BA hormone without Charcoal compared to the both mediums. The number of propagated bulbs ranged from 5 to 6 and 4 to 6 with an average of 5 in Tropicalpink and Greenstar cultivars, respectively. There is little change in the number of newly propagated bulbs in small bulbs of other media. The multiplication process applied in this study may save in vitro culture period and effort.

"Hyehwa" an Asiatic lily cultivar was released in 1998 at National Institute of Horticultural and Herbal Science (RDA), Suwon, Korea. The cross was made in 1991 between Asiatic lily "White Bird", a white colored, and "Avignon", an unspotted scarlet red colored. It was preliminarily selected as A93-20 in 1993. Its multiplication, bulbing growth and flowering characteristic tests were conducted from 1994 to 1998. A new cultivar "Hyehwa" flowers in middle of June and grows 98.7 cm in height. Flowers bloom upward-facing, thick orange (RHS, 28A). Year-round flowering is possible by storage of the bulb under $-1.5^{\circ}C$ conditions. For forcing culture, it is necessary to add calcium to the fertilizer or remove side scales to prevent leaf scorch. Botrytis disease control is needed in the wet season.

본 연구 결과 질산은과 구연산 및 비타민 C의 처리는 레드플레임의 갈변화 방지에는 효과적이나, 레드플레임 인편의 재분화 및 생장에 있어 비타민 C와 질산은의 처리는 효과적 이지 못하였다. 반면 구연산의 경우 레드플레임의 재분화 및 생장에 도움을 주는 것으로 나타났으나 $150mg{\cdot}l^{-1}$이상의 고농도에서는 생육이 저해됨을 보여 $100mg{\cdot}l^{-1}$ 처리가 나리의 재분화 및 생장에 가장 효율적임을 확인하였다. 또한 절편체의 갈변화를 감소시키는 부분에서는 비타민 C $150mg{\cdot}l^{-1}$ 처리가 1.5%의 가장 낮은 갈변율을 나타내어 갈변화 현상 감소에 가장 적합한 처리구로 판단되었다. 본 실험결과는 향후 나리기내 식물체생산에 문제점으로 발생하는 갈변화 현상을 감소시키고 인편 재분화 및 생장을 촉진시켜 우량 나리 기내 묘의 대량증식체계 확립을 통한 우량종구묘 생산체계 확립에 기여하여 농가 소득 향상에 도움이 될 것으로 판단된다.

The cut lily is one of the most important exporting flowers in Korea, which value is 19.9 million dollars in 2013. However, Korean farmers and exporting firms recently have experiences a large decrease in lily export, and need to find the way to the increasing exportation. The purpose of this paper is to analyze the situation of production and consumption of the cut lily in the world and to present the implication for the acceleration of exportation of Korean cut lily. The results of studies present a few findings: First, Korean farmers and business firms need to study and benchmark the production and exportation system of Netherlands which is the best country in the world. Second, Colombia, Kenya, Ecuador and Ethiopia are also need to be studied for the upgrading Korean system of exportation of cut lily. Third, Korean farmers and business firms should continuously monitor the three main markets of cut lily (EU, U.S., and Japan), and develop strategies for the exportation of Korean cut lily. Forth, especially, Korean farmers and business firms should define the preference of cut lily in the main exporting markets (Japan, China, Russia), including breed and color of flower, and the main period of consumption, in order to develop the marketing strategy for Korean cut lily.
