In this study, Pteridophytes flora of Jirisan National Park were recorded 135 taxa, and they belong to 21 families, 39 genera, 123 species, 11 varieties and 1 forma. In the field, 38 taxa were not found on literature exists and 22 taxa were newly confirmed. The results obtained from this study were as follows: Deciduous (d), Evergreen (e) and Summer-deciduous (sd) were calculated as 50.0%, 46.3%, 2.2%, respectively and the Deciduous (d) has the highest value compared to the other leaf phenologies. It observed from the life-form spectra that Hemicryptophytes (H) was the most common dormancy form at 44.8%. Geophytes (G), Epiphytes (E), Hydatophytes (HH), Therophytes (Th) and Chamaephytes (Ch) were calculated at 26.1%, 10.5%, 4.5%, 0.8% and 13.4%, respectively.

The objective of this study is to establish an efficient celll culture system for somatic embryogenesis in Ostericum koreanum and Angelica purpuraefolia. The highest frequency of embryogenic callus on immature seeds of O. konanum and A, purpuraefolia. was obtained when seeds were cultured on MS medium containing 0.1 mg/L 2,4-D and 0.1 mg/L BA. However somatic embryos were formed directly from the edge of cotyledon and hypocotyl of plant which regenerated on medium supplemented with 0.1-3.0 mg/L NAA. Immature seed explane cultured at 25$\pm$2$^{\circ}C$ after 10 days treatment at 5$^{\circ}C$ produced embryogenic callus and somatic embryos, and these differentiated into whole plane. Addition of glutamine and coconut milk to media did not enhance the frequency of somatic embryogenesis in immature seed cultures of A. purpuraefolia. However in immature seed culture of O. koreanum, the frequency of somatic embryogenesis were increased on media supplemented with glutamine and 10% coconut milk. Especially addition of glutamine to the medium substituted effect of NH$_4$N0$_3$ in constast to coconut milk. The highest frequency of conversion somatic embryos into plantlet was 89.1% on MS basal medium Embryogenic calli were grown vigorously when maintained on medium with 0.01 mg/L 2,4-D and 0.01 mg/L BA.

본 연구에서는 한라산의 고도별, 사면별, 계절별 기온(일평균, 일최고, 일최저) 분포와 고산식물의 수직적 분포역을 기초로 고산식물별 온도적 범위를 분석한 후 제주도의 온난화에 따른 한라산 고산식물의 미래를 논의하였다. 아울러 고산지에서의 고도별 기온 분포와 수직적 기온 체감이 환산되어 산악지역에서의 기온 분포를 이해하는데 중요한 자료가 확보되었다. 한라산에서의 100m당 기온체감율은 일평균기온이 -0.58$^{\circ}C$, 일최고기온이 -0.53$^{\circ}C$ 범위내에서 분포가 주로 결정되어, 상대적으로 낮은 최고기온 체감율이 고산식물의 생존에 유리하게 작용한 것으로 보인다. 본 연구에서 얻어진 결과는 온난화에 따른 생태계 변화의 모니터링과 경관 보전 측면에서 유용한 생태적 정보를 축적하여, 한라산에 분포하는 희귀하거나, 멸종위기 상태에 있는 고산식물들의 보전과 관련된 지식이 수립될 수 있다.

In the component ratio of taxa, pteridophyta was 4.2%, 1.2% of gymnospermae, 78.8% of dicotyledonae and 15.8% of monocotyledonae. The rare plants were 9 taxa including Aconitum chiisanense, Eranthis stellata, Aristolochia contorta, Viola albida and so forth. The Korean endemic plants were 13 taxa including Populus tomentiglandulos, Pseudostellaria coreana, Aconitum pseudolaeve, Thalictrum actaefolium var. brevistylum and so forth. The specific plants by floristic region were 16 taxa including Cimicifuga heracleifolia, Sanguisorba longifolia, Symplocarpus renifolius, Betula davurica and so forth. The plants adaptable to climate change were 11 taxa including Aconitum pseudolaeve, Ajuga spectabilis, Carex okamotoi, Rhynchosia volubilis and so forth. The naturalized plants were 20 taxa including Fallopia convolvulus, Rumex crispus, Phytolacca amrericana, Robinia pseudoacacia and so forth. The invasive alien plant was Aster pilosus. The emergence of local ecologically important species, set the correct range for the core and buffer zone, transition zone, coded will be necessary, the distribution of the specialty plant areas and rare plants, an area management plan should be organized by nature. In addition, a variety of assessment techniques and accurate data to establish the validity of the core area is also set to acquire.

지리산국립공원 거림계곡 식물군집구조를 파악하기 위하여 거림계곡 내 등산로를 따라 66개(6,600m2)의 방형구를 설정하였으며 DCA 기법을 이용하여 분석한 결과 해발고 740-950m 의 조사구는 졸참나무군집(군집I) 해발 950-1,340m의 조사구는 신갈나무군집(군집II) 해발 1,340-1,390m의 조사구는 구상나무-거제수나무군집(군집III)으로 분류되었다 상대우점치 흉고직경급별 분포 분석결과 각 군집의 우점종인 졸참나무 신갈나무 구상나무가 우점하는 군집으로 계속유지될것으로 판단되었으며 특히 관목층은 조랫대의 밀도가 높아 천이진행에 영향을 주는 동시에 종다양도가 낮은 것으로 판단되었다 한편 3개 군집간의 유사도지수는 낮은 상태로 해발고에 따라 식생구분이 명확하였다

Climate change are known to have had enormous impacts on plant phenology and thus to have damage on other species which are interacted within ecosystem. In Korea, however, it is difficult to analyze the relationship between climate and phenology due to the limitation of measurement data of plant phenological records. In this study, to be effective analysis of SOG(start of growing season), we used phenological transition dates by using satellite data. Then, we identified the most influential variable in variation of SOG throughout the relationship between SOG and temperature factors. As a result, there is a strong correlation between the SOG and April temperature, TSOGmin($3^{\circ}C$, 12days). This study is expected to be used for predicting plant phenological change using climate change scenario data.

나자식물은 구과목(Coniferales), 주목목(Taxales) 그리고 은행목(Ginkgoales)이 있으며 바늘잎을 가져 흔히 침엽수로 알려졌다. 국제자연보호연맹(IUCN)의 침엽수전문가그룹에 따르면 지구상에 살아있는 구과목과 주목목의 침엽수는 8과 68속의 600여종에 이르며 송백류로 부른다. 남한 면적의 67%에 이르는 660만ha에 삼림 중 침엽수림은 273만ha(42.4%), 침엽수와 활엽수 혼합림은 185만ha(28.8%)로 활엽수의 168만 ha(26.0%)에 비해 훨씬 넓지만 침엽수에 대한 관심은 적다. (중략)
