  • This study was carried out to investigate vegetation of Rhododendron mucronulatum habitat in Mt. Biseul to recommend basic information for synecological characteristics and management methods. The survey was carried out from May to July, 2011 and totally 46 vegetation data including 42 families 93 genera 108 species 16 varieties and 5 forma were collected and analyzed. Among the investigated 129 taxa, the numbers of rare plant resources were summarized as 19 taxa; The rare plants designated by Korea Forest Service, the specific plants by floristic region and the endemic plants were listed as 3 taxa, 15 taxa and 4 taxa, respectively. Rhododendron mucronulatum habitat of Mt. Biseul was classified into 3 plant communities (Carex lanceolata-Rhododendron mucronulatum community, Potentilla dickinsii-Selaginella rossii community, Carex lanceolata-Quercus mongolica community). Carex lanceolata-Rhododendron mucronulatum community was subdivided into Tripterygium regelii subunit and Miscanthus sinensis for. purpurascens subunit by human interference degree. And synecology, syndynamics, synchorology of these plant communities were identified, and Site-species ordination analysis by Principal Coordinate Analysis (PCoA) reflected that human impact, soil moisture condition were main ecological factors determining the distribution pattern of classified plant communities. Therefore these plant communities correspond to quite distinctive 4 habitat types : unstable-dry type=Miscanthus sinensis for. purpurascens subunit, unstable-moderate type=Tripterygium regelii subunit, stable-dry type=Potentilla dickinsii-Selaginella rossii community, stable-moderate type=Carex lanceolata-Quercus mongolica community. Finally, through the vegetational diagnosis, proper management methods such as a limit on the access of visitors, planting of native woody plants after removing unwanted vines or grass were suggested.

  • 희귀 수종인 산개나리(3년생)의 산초지 액아를 배양하여 식물체를 유도하였다. 효과적인 증식법 구명을 위해 MS 배지에서 세 가지 싸이토키닌(BAP, kinetin, zeatin)의 농도별 효과를 조사하였다. 증식은 식물 생장조절 물질이나 농도별 효과가 뚜렷하지 않았으나 zeatin 처리시 줄기 및 잎의 발달에 효과가 있었다. kinetin 처리는 줄기 생장과 더불어 모두 발근되는 특징을 보였고, BAP와 zeatin은 발근은 가능하나 고농도로 갈수록 발근율이 감소하였다. 황화처리는 줄기의 생장을 촉진하였다. 줄기는 3년 이상의 계대배양 후에도 정상적인 증식이 가능했다. 발근된 식물체는 인공 배양토에서 100% 활착되었으며 산지에 이식하여 정상 생장하였다. 이상의 결과는 희귀 수종인 산개나리의 기내 번식으로 자생지의 복원이 가능함을 시사한다.

  • 람사르 습지 지역인 무제치늪의 식물다양성을 파악하기 위해 4개의 늪을 중심으로 2009년 5월부터 2010년 6월에 걸쳐 식물상을 조사하였다. 그 결과 무제치늪 일대의 관속식물은 55과 105속 128종 1아종 16변종 4품종 등 총 149분류군으로 분류되었다. 희귀식물은 자주땅귀개, 작은황새풀, 끈끈이주걱, 땅귀개, 이삭귀개, 꽃창포, 좀바늘사초 등 7분류군이 관찰되었고, 한국특산식물 1분류군, 식물구계학적 특정식물 19분류군, 귀화식물 3분류군이 관찰되었다. 특히, 작은황새풀은 식물지리학적, 진화적으로 중요한 식물로서, 보전하기 위해 심층적인 연구가 요구된다. 무제치늪과 가장 유사한 습생(수생)식물을 가지고 있는 산지습지는 신불산고산습지로 나타났다. 선행연구와 비교결과, 무제치늪 식물상이 조금씩 변화하고 있어서, 지속적인 관심과 적절한 대책이 마련되어야 할 것으로 판단된다.

  • Prangos fedtschenkoi (Regel et Schmalh.) Korovin (Apiaceae) is an endemic species for mountainous Middle Asia, which is both a rare and useful plant. Organic extractions from this species are being used in pharmaceutics and cosmetology. In recent years, P. fedtschenkoi distribution area has considerably decreased, presumably, resulting from human activities such as agriculture, construction works, overgrazing and collection from wild for pharmaceutic purposes. Six populations were found in Uzbekistan and their genetic divergence and differentiation were studied with 10 inter-simple sequence repeat (ISSR) markers, selected out of 101. Totally 166 amplified ISSR fragments (loci) were revealed, of which 164 were polymorphic. Relatively moderate level of polymorphism was found at population level with polymorphic bands ranging from 27.71% to 47.59%. Mean P = 39.05%, $N_a=1.40$, $N_e=1.25$, S.I. = 0.21, and $H_e=0.14$ were revealed for all loci across six populations. AMOVA showed higher variation among populations (62%) than within them (38%). The Bayesian model determined 5 clusters, or genetic groups. The posteriori distribution of the Theta II estimator detected full model identifying high inbreeding, intensified by low gene flow (Nm = 0.3954). Mantel test confined population 6 as distinct cluster corresponding to geographic remoteness (R = 0.5137, $p{\leq}0.005$). Results were used as the bases for developing conserve measures to restore populations.

  • The vascular plants in the Mt. Manduk was listed 560 taxa composed of 110 families, 345 genera, 488 species, 1 subspecies, 67 varieties and 4 forms. Based on the list of the rare plants by the Forest Research Institute, 4 taxa were recorded in the studied areas; Lilium distichum (Preservation priority order; No. 159), Tricyrtis dilatata (No. 97), Aristolochia contorta (No. 151) and Prunus yedoensis (No. 110). Based on the list of Korean endemic plants, 12 taxa were recorded; Cephalotaxus koreana, Carex okamotoi, Lilium amabile, Populus tomentiglandulosa, Salix purpurea var. japonica, Pseudostellaria multiflora, Prunus yedoensis, Stewartia koreana, Forsythia koreana, Paulownia core ana, Weigela subsessilis and Aster koraiensis. Based on the list of approved for delivering overseas of plants, 7 taxa were recorded; Carex okamotoi, Lilium distichum, Aristolochia contorta, Vaccinium oldhami, Paulownia coreana, Asperula lasiantha and Saussurea seoulensis. Specific plants by floral region were total 32 taxa; Prunus yedoensis in class V, Wistaria floribunda in class IV, 5 taxa (Girardinia cuspidata, Spiraea salicifolia, Acer palmatum, Stewartia koreana, Asperula lasiantha) in class III, 3 taxa (Potentilla dickinsii, Viola tokubuchiana var. takedana and Caryopteris incana) in class II and 22 taxa (Pinus koraiensis, Hosta capitata, Chloranthus japonicus, Salix glandulosa, Juglans mandshurica, etc.) in class I. The naturalized plants in the surveyed sites were 14 families, 36 genera, 44 species, 2 varieties, 46 taxa and naturalization rate was 8.2% of all 560 taxa of vascular plants. Wild plants disturbing ecosystem like Ambrosia artemisiifolia var. elatior have been increasing. Therefore, continuous control and conservation measures are needed on the ecosystem of Mt. Manduk.

  • 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.
