  • The current status of geographical distribution range of Deutzia paniculata, one of the korean endemic plants, was investigated based on the species distribution information. The information of the geographical range used for analysis includes all the published references to the distribution of D. paniculata, herbarium specimens in Korea National Arboretum (KH) including its online database: http://www.nature.go.kr, and field research. Although, D. paniculata was firstly recorded in Wonsan, Hamgyeongnam-do, North Korea, this research revelaved that D. paniculata is mainly distributed in Gyeongsangbuk-do and Gyeongsangnam-do, southern regions of the Korean Peninsula. According to the distribution map, this species was estimated on distribution edge of in Anyang region of Gyeonggi-do, Mt. Naejang of Jeollabuk-do and Mt. Taebaek of Gwangwon-do on the distribution edge. However, it was made use of intensive field survey to identify the natural population of the species in these regions. D. paniculata habitat was mainly distributed between 290 meters and 491 meters in altitude, but it was also found ranged from 936 to 959 meters in Gun-wi, Gyeongsangbuk-do, South Korea. The distribution slope was 5° to 35° and the north, N, NE and NW in the aspect. The flora of vascular plants in D. paniculata habitats was listed in 137 taxa: 54 families, 103 genera, 120 species, 2 subspecies, 12 varieties and 3 forms while Korean endemic plants were found in three taxa, Stewartia koreana, Weigela subsessilis and D. Paniculata. Based on a collection of non-biological environment and biological environment data, D. paniculata population were discussed to make strategy and basic research methods for sustainable preservation.

  • 꼬리말발도리(Deutzia paniculata Nakai)는 전 세계적으로 우리나라 경상남북도 일부지역에만 자생하는 매우 제한된 분포범위를 가지는 특산식물이다. 이러한 꼬리말발도리 집단의 유전적 다양성 및 구조를 조사하기 위해 5집단 155개체에 대한 ISSR(Inter Simple Sequence Repeat) 분석이 수행되었다. 총 6개의 ISSR 프라이머를 이용하여 31개의 증폭산물을 관찰하였으며, 집단 수준에서의 유전적 다양성의 평균은 SI(Shannon's information index)=0.429, h (Nei's genetic diversity)=0.271로, 매우 높은 수준으로 나타났다. 집단별로는 큰 차이는 없었지만 비교적 높은 개화율을 보이는 밀양, 양산 집단이 다른 집단에 비해 다소 높은 유전 다양성을 유지하고 있는 것으로 나타났다. AMOVA 분석 결과 전체 유전변이의 약 16%가 집단 간 차이에 기인하는 것으로 설명되었으며, 나머지 84%는 집단 내 개체간에 존재하는 것으로 나타났다. 이처럼 제한된 분포범위를 가지는 꼬리말발도리 집단에서 나타나는 높은 유전다양성과 집단간 낮은 유전적 분화율은 완전 타가수정하는 교배양식과 집단내 비교적 풍부한 개체수의 영향인 것으로 판단된다. 따라서 현재의 유전다양성을 유지할 수 있는 적절한 현지 내 보전대책 수립이 요구된다.

  • A taxonomic revision of Deutzia in Korea was conducted based on critical observations of wild populations and herbarium specimens. Species delimitations were re-evaluated on the basis of morphological characters and distributions resulting in the recognition of five taxa. The texture of leaf, flower disk and capsules, the shape of leaf, inflorescence and capsules are useful diagnostic traits at the specific level. The five taxa are well distinguished from each other. Deutzia grandiflora var. baroniana can be distinguished by its distribution and calyx from Deutzia uniflora, which are morphologically similar. Deutzia paniculata Nakai, a rare and endemic plant, is characterized by having panicle in inflorescences. On the other hand, Deutzia glabrata Kom. is occasionally confused with Deutzia parviflora, but the most distinctive characters include the surface of leaves, the surface and size of capsules. Photographs and a key to five species of Deutzia were provided in addition to distribution.

  • 고유식물인 꼬리말발도리는 팔공산, 달음산, 가지산과 운문산 등 경상남북도에 제한적으로 분포한다. 본 연구대상인 4개 집단의 크기는 달음산의 최소 100개체에서 운문산 집단이 최대 3,500개체까지이다. 인공수분실험 결과, 생식양식은 완전 타가수분이며, 주요 관찰 화분매개자는 Lasioglossum exiliceps (Vachal)과 호리꽃등에 [Allograpta balteata (de Geer)]였다. 동위효소로 유전적 다양성을 측정한 결과, 종 수준에서의 평균적인 유전다양성은 유전자좌 당 평균 대립유전자수($A_s$)는 1.33, 유전다양성($H_{es}$)은 0.110으로 이미 보고된 고유식물종의 유전다양성과 비슷한 값을 보였다. 달음산 집단은 모든 개체에서 동일한 유전적 조성을 보였으며, 이 집단의 전체 개체가 클론으로 추정된다. 유전자좌의 비율(P)과 유전자좌당 평균 대립유전자($A_P$)의 수는 팔공산 집단이 가장 높았다. 집단 간의 전체 유전 고정지수($F_{IT}$)는 집단 내 지수($F_{IS}$)보다 높아 집단 내 이형접합자의 비율은 높지만, 종 전체 이형접합자 부족현상이 확인되었다. 집단 간의 유전적 분화의 정도를 나타내는 $F_{ST}$값은 0.223, 각 집단 간의 유전적 거리는 평균 0.047(0.011-0.066)로 단형성을 갖는 유전자가 많아 실제 분화는 일부 유전자좌에 국한된 결과이다. 꼬리말발도리의 유전다양성의 감소는 집단의 유효집단 크기 감소와 관련이 있으며, 현지내의 생육지 보전과 함께 현지외 보전을 위해 각 집단별로 최대 유전 다양성을 확보하는 전략이 필요하다.

  • Deutzia paniculata Nakai, a rare and endemic plant, has limited distribution throughout the North and South Gyeongsang provinces of South Korea. The D. paniculata community grows mostly on the stony slopes of forests, valley edges, and rock layers at 250-960 m in altitude, where deciduous trees are dominant and high humidity is maintained. Correlation analysis of vegetation and environmental factors found that the Walter's dogwood-mulberry community was correlated with soil acidity (pH). Whilst the queritron community had correlations with distance from the valley, rock rate and slope. The natural habitat of the Palgongsan Mountain in Daegu is known to have high genetic diversity, had eight D. paniculata individuals recorded from 2014 to 2018, and 12 individuals recorded in 2020 (new individuals due to a newly created space within the herbaceous layer caused by grass mowing works), it is therefore unlikely that the community would perish unless there was an artificial disturbance. To conserve the natural habitats of D. paniculata, oppression by Sasa borealis, damage, increase in crown density of the upper layer, overexploitation, and absence of seedlings should be carefully investigated. In addition, response measures should also be established and the impact on seed fullness and the reproductive characteristics of D. paniculata recorded. To restore declined genetic diversity, individuals from high genetic diversity regions, such as Palgongsan Mountain, should be artificially transplanted.

  • As the importance of biological resources increases, the conservation technology is becoming important for rarities. This study was conducted to establish an efficient cryopreservation conditions for the Deutzia paniculata, endangered plant species, by using both cryopreservation methods of vitrification and encapsulation. As a result, the sucrose pretreatment seed viability showed up to 30.7% in the treatments. The cryoprotectant treatment improved the viability of the seeds, and was found to be excellent in the vitrification method using PVS3. The vitrification method had over 10% higher germination rate than the seeds preserved by encapsulation. In addition, the germination rate showed a significant difference according to the cryopreservation treatment time, and the germination rate of seeds decreased very much as the long time became longer. Plants germinated from preserved seed in liquid nitrogen showed poor growth compared to untreated, and good growth in PVS3 120 minutes. In addition, the growth of germinated plants by liquid nitrogen treatment time was better in the vitrification method. These results are expected to be useful for long-term preservation of D. paniculata, endangered plants.

  • In this study, we investigated the effect of seed collection stage and alternating temperature on the germination of Deutzia paniculata (Hydrangeaceae). The seeds were collected from naturally growing D. paniculata populations in Mt. Palgong, Gyeonsangbuk-do, Korea every two weeks over a three month period from August through October, 2014, totaling five collections. We examined seed characteristics such as seed size (length and width) and weight, and germination percentages for each collection stage under four different germination temperature regimes. We also examined germination after 30 and 60 days of cold moist stratification. Each collection phase had a different germination percentage and the lowest germination percentage was observed in the seeds from phase I (average GP of 15.7%). The germination percentage was similar at the later collection phases and in the higher temperatures suggesting that later collection times and higher temperatures are optimal for D. paniculata germination. We found that the optimum collection stage with high viability and germination percentage of for D. paniculata was during the middle of the September.

  • 꼬리말발도리는 한반도 특산식물임에도 불구하고 종의 분포, 개체군 및 자생지 특성, 그리고 이것에 기초한 종 보전 연구를 찾아보기 어렵다. 본 연구는 꼬리말발도리를 대상으로 종 분포 및 생태 특성을 분석하였다. 꼬리말발도리의 분포 특성은 문헌, 표본 및 현장 조사 자료를 참고하였다. 현장 조사는 6개 지역에서 11개의 대방형구 ($15{\times}15m$)와 33개 소방형구 ($5{\times}5m$)의 자생 집단을 대상으로 2014년 5월부터 10월까지 실시하였다. 개체군 특성으로 풍부성(밀도, 피도), demographic 속성 (개화율 및 결실율)이 조사되었으며, 자생지 특성으로 식생 (구조 및 종조성), 임내광량 (광량, 수관열림도) 및 토양 (온 습도, 이화학 속성) 특성을 분석하였다. 꼬리말발도리는 경상도 (강원도 태백 포함)가 분포 중심이었으며, 넓은 해발 분포 범위 (평균 493 m, 및 해발 290~959 m 범위)를 나타내었다. 꼬리말발도리 자생지의 평균 사면경사는 $16^{\circ}$ ($7{\sim}35^{\circ}$ 범위)이었으며, 주로 너덜 계곡 입지 및 그곳과 접한 사면하부에 분포하였다. 꼬리말발도리 개체군의 소방형구 ($5m{\times}5m$) 내에서 평균 12.5개체가 출현하였고, $m^2$당 평균밀도는 0.5를 보였다. 평균 개화율은 15%로 낮은 개화율을 보이며 영양생식에 의한 번식이 빈번히 이루어지는 것으로 판단된다. 꼬리말발도리 자생지의 조사구 수준 식물상은 138분류군이었다. 꼬리말발도리 자생지의 식생은 너덜 입지환경을 잘 반영하는 층층나무 (중요치 25.5%) 및 물푸레나무 (중요치 15.8%)가 우점하는 서식지로 나타났다. 층층나무 유형은 급경사 지역, 그리고 물푸레나무 유형은 주로 높은 해발고도에 분포하는 특성이 관찰되었다. 연구 결과, 꼬리말발도리는 인간 활동보다는 범람과 같은 자연 교란, 기후변화 및 진화 생태학적인 요인에 의해 개체수의 변동이 예상되는 종으로 판단되며, 개체군 및 자생지의 지속성을 위협하는 뚜렷한 증거는 찾아볼 수 없었다.

  • This paper aims at surveying through case studies the planting possibility on the interval artificial ground between the bank and the core landfill of the first section of works in the SUDOKWON Landfill area landfill area which was completed, followed by the layer-on-layer landfill process involving the latch or sealing layer against emitting landfill gas from the reclaimed waste. The survey results are as follows; 1. The layers of the artificial planting ground on the landfill were established on the basis of top-on-top procedure for a waste layer, a topping soil layer (T=50cm), a gas blocking layer (broken stones T=30cm), a filter layer (non-woven fabric 700g), a sheet protecting soil layer (T=20cm), and a blocking layer (HDPE SHEET 2.0mm), an irrigation layer (SAND T=30cm), a filter layer (non-woven fabric 700g), a sheet protecting soil layer (T=20cm), and a blocking layer (HDPE SHEET 2.0mm), an irrigation layer (SAND T=30cm), a filter layer (non-woven fabric 700g), a planting layer (T=90cm+), a top mound (T=2m). 2. Since no direct damage on the planting layer affected by the landfill gas was detected, planting is found to be still possible and successful except the severely unequal subsidence portion. 3. The mortality rate is discovered different on different trees: Pinus thunbergii (H3.0$\times$W1.0m) 11.25%, Pinus thunbergii (H2.5$\times$W0.8m) 4.73%, Koelreuteira paniculata 8.67%, Hibiscus syriacus 5.68%, Deutzia parviflora 6.50%, Forsythia koreana 8.17%, Rho. yedoense v. poukhanese 32.22%, and Spiraea pru v. symplicifolia 18.89%; although the last two of which are generally considered to have a strong generic growing character, they are subject to be weakened when exposed to the contaminated microclimate of the site like landfill gas. 4. The damage rates, on Pinus thunbergii, Koelreuteria paniculata, Hibiscus syracus, Forsythia koreana, Deutzia parviflora, Rho. yedoense v. poukhanense were shown to decrease to 7.31-17.69% in the second check (June 2000) lower than 5.77-46.92% in the first examination (June 1999), whereas the damage on Spiraea pru v. symplicifolia relatively increased. It is believed that preparatory method of the air pollution, change of temperature, odor by emitting landfill gas, and minute dust from vehicles should be made, and a research on this matter will be conducted in the near future.
