This study was carried out to reveal optimum conditions for in vitro propagation of 3 Korean native azalea species, Rhododendron mucronulatum, R. yedonese var. poukhanense, and R. shlippenbachii, which are useful for landscape proposes. Seeds and meristems from three azalea species were cultured on 1/2MS, Hyponex, and Anderson media containing growth of regulators benzyladenine(BA) and 2-isopentenyadenosine(2ip). The results were as follows. 1. In the culture of R. schlippenbachii and R. mucronulatum seeds, in vitro seedlings germinated and grew well on he 1/2MS and Anderson media, while R. yedoense var. poukhanense on Hyponex media containing 6.0mg/$\ell$ 2ip. 2. When the meristems of R. mucronulatum were cultured on Andeson media containing 9.0mg/$\ell$ 2ip, the survival rate of meristems was 23.0% in 6 weeks after culture, and the survival rate of R. schlippenbachii was 46.0% o nthe same media containing 12.0mg/$\ell$ 2ip. The survial rate of R. yedoense var. poukhanense was 92.0% onHyponex media containing 0.5mg/$\ell$ BA and 9.0mg/$\ell$ 2ip. When the meristems of R. mucronulatum and R. yedoense var. poukhanense were cultured on Hyponex media containing 12.0mg/$\ell$ 2ip, they showed the most excellent growth. R. schlippenbachii grew well on Anderson media containing 9.0mg/$\ell$ 2ip. When in vitro shoots of R. yedoense var. poukhanense were subcultured to solid medium, they grew well in shoot growth on Hyponex media containing 6.0mg/$\ell$ 2ip.

1. The plant communities on Mt. Sulak, a typical alpine mountain in central Korea was researched from the standpoint of ecological survey. 2. The plant on this mountain can largely be classified into 2 categories, the warm zone (below 1100m) and the frigid zone. The former is again classified into a broad-leaved tree formation and a needle-leved tree formation, and the latter is calssified into a broad-leaved tree formation and needle-leaved tree formation, and shrub formation. 3. The broad-leaved tree formation in the warm zone can largely be classified into a Carpinus laxiflora-syringa Palibiniana var. kanibayashi association(1), a Carpinus erosa-Acer Pseudo-sieboldianun association(2), and a Quercus mongolica- Tripterygium Regelii association(3). 4. The needle-leaved tree formation in the warm zone can also largely ben classified into a Pinus densiflora- Miscanthus sinensis association(4), Abies holophylla- Tripterygium regelii association(5), Pinus kordiensis- Rhododendron schlippenbachii association(6) In the association(4), the canopy of the Pinus densiflora is gradually being occupied by the Quercus mongolica which is one kind of broad-leaved trees. 5. We can fully see a DryoPteris type of the flour layer plant type in the association (3) and also see a Sasamorpha type in the association (5). 6. The broad-leaved tree formation in the frigid zone can largely be classified into Quercus mongolica- Rhododendron schlippenbachii association (8). The constituents of tree and subtree layers in (7) and (8) associations are similar to those association (3), but the constituents of the shrub layer are different from those of associtation (3) due to the difference in height. 7. The needle-leaved formation in the frigid zone can largely be classified into Thuja koraiensisRodgersia podophylla var. viritis association (9) and Abies nephrolepis-Acer tschonoskii var. rubripes asscciation (10). The species of alpine plants or subalpine plants are gradually increased in this formation. 8. The shrub formation can also largely be classified into a Rhododendron mucronulatum- Patrinia saniculaefolia association (11) and Pinus pumila associatio (12). Association (12) has largely developed on the windy place. Association (12) was burned due to the bombing during the Korean war, but now we recoginized there occurred an invasion of Tripterygium Regelii in such a place. 9. The herb layer species which constitute the shrub formation are mostly alpine or subalpine plants of small size, and their kinds are also very few. 10. The growth of the Moss layer is especially good because of the varied conditions of the habitat. The kinds which can easily be seen are the genus of Thunidium, Haplocladium, Brachythecium, Macromitrium, Holonitrium, Atrichum, Schwstchkeopsis, Grimmia, Hedwigia, Rhynchostegium and Mnium. 11. The genus of the Sphagnum densly grows like a mat at the acid and moisturous place above 1100m. The authors should express their thanks to father. Yang Kisup, Dean of Catholic Medical College, Prof. Yoon Doksuen, from their valuable advice. Thanks arealso due to Prof. Numata, Chiba University, Prof. Takagi, Nagoya University and Prof. Ando, Hiroshima University in Japan for his kind help and identification of Bryophytes.

본 연구는 계방산 온대북부 낙엽활엽수림에서 하층식생(관목층과 초본층)의 식생조성 변화를 구명하였다. 조사지에 출현하는 식물은 56과 93속 124종 17변종 3품종 2아종 1미분류군으로 총 146분류군이 조사되었으며, 종면적 곡선에서 초본층과 관목층의 종수는 시간이 경과함에 따라 감소하는 것으로 나타났다. Mantel-test 분석 결과, 상층의 기저면적은 하층의 변화에 영향을 주는 인자 중 하나로 분석되었다(p < 0.0001). 평균중요치는 관목층에서 생강나무(21.585%), 철쭉(19.774%)이 우점하는 것으로 분석되었으며, 초본층에서는 조릿대(14.082%)와 생강나무(7.921%)가 우점하는 것으로 나타났다. 관목층의 NMS 배열 결과, 높은 연관성을 가지는 종은 시간이 경과함에 따라 감소하는 것으로 분석되었으며, 상층의 기저면적 증가에 따라 반응하는 종이 다른 것으로 분석되었다. 초본층 조사구의 NMS 배열 결과, 관목층의 철쭉과 진달래가 지속적으로 영향을 미치는 것으로 분석되었다. 그리고 MRPP-test에 대한 식생조성의 변화 결과, 관목층은 5년 그리고 10년에 따른 식생조성의 변화가 유의차가 없는 것으로 분석되었다. 하지만 초본층은 5년 그리고 10년에 따른 식생조성의 변화가 유의성 있게 분석되어, 하층식생 중 초본층의 종조성은 관목층보다 종조성의 변화가 큰 것으로 나타났다.

Species composition and the amount of nutrients absorbed by regenerating plants on a pine forest in the immediate postfire year were compared with those in an unburned pine forest in Kosung, Kangwon Province. Pteridium aquilinum var. latiusculum, Cyperus amuricus, Lespedeza biolor, Quercus serrata, Lysimachia clethroides were the most abundant species in burned area. In unburned area. Quercus mongolica, Rhododendron mucronulatum, Carex humilis, Rhododendron schlippenbachii, Spodiopogon sibiricus were the most abundant species. Standing biomass of understory vegetation in burned and unburned area was 170.2 g $D.W/m^2$ and 171.3g $D.W/m^2$, respectively. Nutrient concentrations of plants in burned area, especially for phosphorus and potassium, were higher than those in unburned area. The amounts of nutrients absorbed by understory plants in burned and unburned area were 37.4 and 33.6 kg/ha for N, 0.36 and 0.19 kg/ha for P, 30.6 and 18.8 kg/ha for K, 8.5 and 7.8 kg/ha Ca, 5.2 and 5.7 kg/ha for Mg, respectively. This suggests that regenerating vegetation can hold the significant amount of nutrients, although there may be considerable losses of nutrients from ecosystem after fire.

The forest vegetation of Mt. seondal was classified into eight communities and one afforestation by the phytosocialogical method (Z-M method). In general, Quercus mongolica trees occupied most of the area, while afforestation forest was distributed on the lower slope, cultivated land, and at the vicinity of village. The vegetation on the top part of Mt. Seondal was comparatively well preserved, but that in the lower areas has been disturbed heavily by human activity and some had mixed forests composed of pine trees, oaks, ashes, and Rhododendron micrantum shrub. By cluster analysis method. nine groups were identified as follows : Quercus mongolica group, Q. mongolica - Pinus densiflora group, Q. mongolica - Rhododendron schlipen - bachii group, Q. mongolica - Symplocos chinensis for. pilosa group, P. densiflora group, Juglans mandshurica group, Fraxinus mandshurica group, Betula costata group and Larix leptolepis group. These groups showed differences in species composition, but Quercus mongolica, Q. mongolica - P. densiflora, Q. mongolica - R. schlippenbachii and Q. mongolica - S. chinensis for. pilosa groups among them showed very similar floristic composition to each other. In the relationship between polar ordination axes and environmental variables, altitude was the environmental factor determining variation in species composition along axis X and soil moisture was the environmental along axis Y. They were the main factors in determining forest vegetation. The result of cluster analysis and polar ordination for the forest vegetation were corresponded to those of phytosocialogical classification in classifying vegetation.

The forest vegetation of natural reserve area (175ha) at north-eastern slope of Solibong (537m), Gwangneung, was studied by plant sociological method and two dimensional ordination technique. In the area dominated by Carpinus laxiflora, from the lower site to peak of Solibong, a zonal distribution of C. laxiflora-Quercus mongolic forest, C. laxiflora-C. cordata forest, C. laxiflora-Q. serrata forest, C. laxiflora forest and C. laxiflora-Rhododendron schlippenbachii forest were recognized by the plant sociological survey. It is seem that the optimal range of Carpinus laxiflora forest occur in mesic-warm site by two dimensiional ordination with thermal condition and soil moisture condition. The optimal range (over 100 in importance value) was the range of 76~89。C.month in warmth index and 18~45% in soil water content.
