This study aimed to elucidate the distribution of vascular plants on the Deok mountain in Ganghwa-gun, Korea. The results of 10 field surveys from March to October of 2019 identified 532 taxa in total, representing 482 species, 9 subspecies, 39 varieties, 1 form, and 1 hybrid in 318 genera and 105 families. The plant formation of Deok mountain is the deciduous broad-leaved and conifer mixed forest, which is the common one in the middle region of the Korean Peninsula. Among them, 301 taxa were newly recorded in this study, 7 taxa were endemic plants to Korea, 3 taxa were red list plants. The floristic target plants amounted to 41 taxa, specifically 1 taxon of grade V, 2 taxa of grade IV, 7 taxa of grade III, 9 taxa of grade II, and 22 taxa of grade I. Alien plants were recorded a total of 73 taxa with a naturalized index of 13.7%, the urbanization index was calculated to be 11.8% and 4 taxa were ecosystem disturbance plants.

High frequency plant proliferation system via direct frond regeneration of endemic duckweed plants Lemna paucicostata and Spirodela polyrhiza was established. Fronds of L. paucicostata and S. polyrhiza were able to multiply half-strength MS basal medium without plant growth regulators. However, addition of BA at a range of 1 to 3 mg/L was more effective than high concentration of BA treatments for fronds proliferation. Also half-strength MS salts was suitable for the fronds proliferation. Increase of salts concentration had inhibitory effect on fronds proliferation. Also the frequency of callus formation from fronds of L. paucicostata was 3.3%, when they cultured onto 1/2 MS medium supplemented with 1 mg/L of BA. Similarly the frequency of callus formation from S. polyrhiza was very low. After subculture of white globular structures derived from fronds of L. paucicostata, numerous globular somatic embryos and calluses were developed onto the surface of fronds. However these somatic embryos did not fully develop into normal plants when transferred to 1/2 MS basal medium. Therefore direct frond regeneration system was more efficient for mass proliferation of L. paucicostata and S. polyrhiza. The plant regeneration system of L. paucicostata and S. polyrhiza established in this study, might be applied to mass proliferation and genetic transformation for molecular breeding.

본 연구는 국내 특산식물이며 관상소재로 개발이 가능한 산꼬리풀의 효과적인 육묘조건을 구명하기 위해 수행되었다. 육묘는 토양 종류와 비료 농도, 차광정도, 추비 농도, 종자의 광원 전처리 및 채종 시기별로 각 요인을 달리하여 수행하였다. 연구 결과, 산꼬리풀은 원예상토에서 생육이 우수하였으며, 혼용토에서는 비료 첨가 시 생육이 억제되었다. 차광은 55% 차광조건에서 무차광에 비해 전체적인 생육이 향상되었다. 고농도(1000mg·L^-1)의 Hyponex는 육묘 시 생육을 촉진하였으며, 파종 전 종자에 대한 적색광 조사는 추후 초장과 생체중 향상에 효과적이었다. 채종 시기는 2018년도 종자가 2017년 종자보다 생육이 우수하였다.

This study was carried out to investigate the flora of six islands belonging to the Gogunsan Archipelago (i.e., Sinsi-do, Seonyu-do, Munyeo-do, Yami-do, Bian-do, and Duri-do) in the Korean Peninsula. As results of five field surveys from March to October of 2016, we have identified 575 total taxa, representing 527 species, five subspecies, 42 varieties, and one hybrid, placed in 358 genera and 118 families. Of these 575 taxa, four are endemic to Korea, six taxa are listed on the Korean Red List of threatened species, 67 are floristic regional indicator plants, and 74 are invasive alien species. In this study, we compared species richness among the islands, and find that the larger the islands, the higher the species richness. In the case of habitat affinity types, forest species were most common, followed by farmland, seacoast, bare ground and wetland species. From similarity analyses based on the composition of vascular plants, each island did not exhibit either local specificity or unique diversity. On the contrary, the proportion of invasive alien and ruderal species may increase by human activities. Investigations and analyses of island flora such as this are important to assess the current status of the flora, predict future vegetation patterns and the spread of the alien species, and establish managment plans of plant diversity.

우리나라 특산식물인 매미꽃(Coreanomecon hylomeconoides Nakai) 집단의 유전적 다양성 및 구조를 조사하기 위해 8집단 224개체에 대한 ISSR(Inter Simple Sequence Repeat) 분석이 수행되었다. 총 8개의 ISSR 프라이머를 이용하여 50개의 증폭산물을 관찰하였으며 집단 수준에서의 유전적 다양성의 평균은 P (Percentage of polymorphic loci) = 47.3%, SI(Shannon's information index) = 0.218, h (Nei's genetic diversity) = 0.142로 다년생 초본류의 평균보다는 월등히 낮게 나타났다. 집단별로는 분포의 중심에 해당하는 산청(SI=0.233, h=0153), 광양(SI=0.263, h=0.171), 순천(SI=0.241, h=0.159) 집단이 남해(SI=0.183, h=0.116)나 광주(SI=0.181, h=0.121)의 변두리 집단보다는 비교적 높은 유전다양성을 유지하는 것으로 나타났다. AMOVA 분석 결과 전체 유전변이의 약 18%가 지역 간에 나머지 82%가 집단 내 개체간의 차이에 기인하는 것으로 나타났는데 이는 집단 간에 유전자 교류가 원활히 이루어지기 때문으로 판단된다. 유전적 거리를 이용한 UMGMA 유집분석과 Bayesian cluster 분석 결과, 매미꽃 집단은 동서 두 지역으로 구조화 되는 경향을 보여 주었는데 이는 집단의 지리적 분포 패턴의 영향인 것으로 추정할 수 있다. 본 연구 결과, 조사된 다른 집단보다 풍부한 개체수와 높은 유전 다양성을 유지하고 있는 지리산 및 백운산의 산청, 광양 집단들에 대한 적극적인 현지 내(in situ) 보전대책 수립이 요구된다.
