  • To explain the horizontal expansion of a rhizomatous perennial, Convallaria keiskei(lily-of-the-valley), in a study site of Chunchon, Kangwon Province, Korea, ramet growth and clonal structure were studied. Remarkable growth stategies were clarified. First, the timing for the successive phenological events such as sprouting. flowering and rhizome growth for lily-of-the-valley was fitted to exploit early spring when the canopy of overstory was opened. Second, these events were supported by effective matter allocation pattern: for example, two-year investment for new rhizomes enabled the first year ramets to mature in six weeks after sprouting and to grow up to 85% of the leaf area of perennial ramets. Finally, the ramet population was increased by local disturbances such as freezing, herbivory and collection by human. The rule that a clone was supposed to produce one new thizome per year was broken by occasional disturbances. Then, up to 5rhizomes from latent bur could be redeveloped. Based on clonal structure, 80% or total clones have from 1 to 4 ramets. this means there have occurred minor disturbances. Therefore, in conclusion, the successful flourishing of lily-of-the-valley came from its effective frowth strategy to take advantage of site disturbance.

  • Aqueous extracts of medicinal plants traditionally used in the East Asia such as China, Korea, and Japan were screened for inotropic activity using isolated rabbit atria. Among the twenty-one aqueous-extracts from medicinal plants, the aqueous extracts of Convallaria keiskei(ACK) and rhizome of Coptis chinesis (ACC) were found to exhibit distinctive positive inotropic activity. The aqueous extracts of C. keiskei and rhizome of C. chinensis significantly increased atrial stroke volume and pulse pressure in beating rabbit atria. These findings suggest that the aqueous extracts of C. keiskei and rhizome of C. chinensis enhance the cardiac muscle contractility and then could be useful for the treatment of cardiac failure.

  • This survey has been carried out on ten species(Erythronium japonicum, Symplocarpus renifolius, Adonis amurensis var. ramosa, Corydalis turtschaninovii var. genuina, Primula sieboldii forma spontanea, Anemone raddeana, Gagea Iutea, Heloniopsis japonjca, Hylomecon japonicum, and Convallaria majalis var. keiskei in the undergrowth of a forest of deciduous broad-leaved trees in the Kwangnung area of Kyung-Ki Province. They always bloom towards the end of March which is earlier than most of the other plants do. They completely finish up their matter productions before foliage of the deciduous trees, which are the upper strata plants, grows broader or to cite in other terms, before the relative light intensity in the lower strata is fallen to the lowest degree to become to insufficient to allow for photosynthesis. These phanerophytes naturally wither down between June and July. The above mentioned phenomenon clearly demonstrates a kind of the ecological niches and habitat segregation in terms of using sunlight to her greatest advantage. Soon after these herbs wither they make their own winter buds-life form-around their roots and then go into hibernation. The intensity of light in this forest zone was measured through the use of a lux meter in order to investigate it's seasonal variations. In additions, an intensive survey on the duration of their efflorescence was fullfilled.

  • The golf course has many problems that are a pollution of river, a extinction of habitat by destructing a forest and a simplication of species composition. Therefore, this study was carried out to examine the ecological characteristics of vascular plants in construct-reserved site of golf course. The results were as follow. The vascular plants were summarized as 342 taxa; 86 families, 231 genera, 295 species, 42 varieties and 5 forma. In the results by the location environments of vegetation, Salix caprea community and wetland species like Persicaria thunbergii were appeared in the swamp. Especially, S. caprea will be made use of promoting a landscape. In the stream, Stephanandra incisa community has a functions like an ecological axis and a corridor of wild animals. The planting technique will be applied to using Atractylodes japonica and Ainsliaea acerifolia in the lower part of Pinus densiflora and Quercus mongolica. Because Rhododendron schlippenbachii and Convallaria keiskei grew by layer in Q. variabilis community, this will be made use of natural vegetation model. The rare plants were 2 taxa; Aristolochia contorta and Iris ensata var. spontanea. To preserve their community, we will prohibit a development and remove a threatening factor. The endemic plants were 4 taxa; Salix caprea, Clematis trichotma, Spiraea prunifolia for. simpliciflora and Weigela subsessilis. The naturalized plants were 19 taxa; Rumex crispus, Bildedykia dumetora and so on. To establish the quantitative management plan, we will obtain a ecological information about a naturalized plants in accumulating by season, community and land use pattern.

  • 울산 무제치습원에 대한 생태식물상(ecological flora)과 군락유형분석이 이루어졌다. 군락유형분석은 Zurich-Montpelliar의 연구방법으로 식생유형 분류와 분포적 특성, 그리고 종조성적 군락동태를 파악하기 위하여 식생자료간의 거리(유사성)와 속성에 대한 집괴분석법 및 PCoA (Principal Coordinate Analysis) 좌표결정법이 적용되었다. 주요 감시종 13종을 포함한 습지성 식물종 49종과 중간습원 식물군락을 포함한 6개의 식물군락이 분류되었다. 식생유형은 쇠털골-좀고추나물군락, 바늘골-끈끈이주걱군락, 진퍼리새-하늘산제비난군집(신칭), 오리나무-진퍼리새군락, 소나무-억새군락, 졸참나무-은방울꽃군락 등이 기재되었으며, 동북아 산지성이탄습지의 중간습원을 대표하는 식생으로 진퍼리새군강이 새롭게 제창되었다. PCoA는 무제치습원 속에 현존하는 식물군락간의 종조성적 상이성이 토양의 수분구배와 식물군락의 층구조(생체량)에 대응하는 네 개의 천이식생형(쇠풀골형, 진퍼리새형, 억새형, 삼림형)으로 구분하였으며, 건생의 타생천이계열과 습생의 자생천이계열이 존재하고 있음이 밝혀졌다. 중간습원으로서 무제치습원에 대한 식생의 종조성과 분포의 지속성은 토사 및 영양염류의 비정상적 유입을 방지하는 습원생태계의 수문체제와 토지조건의 적극적인 고려로부터 가능하다는 것을 밝혔다.

  • This investigation was one of the series of ecological studies on the plant communities of Quelpart Island which was held in 1969. It was aimed at studying the ground vegetation of Torreya nucifera and the soil properties of the ground in which it grows. Observaton of the flora in a place where wild growth of Crinum maritimum, soil properties and distribution of micro-organisms in a place where wild growth occurs, were also made. 1) A few kinds which have important values among the ground vegetation fo Torreya nucifera forest are Liniope graminifolia, Convallaria keiskei, Sasaquelpaertensis, Carex kingiana, Pteridium aquilinum, Pyrola japonica, Hedera tobleri, etc. 2) While the studies of 25 Quadrats were being held, 29 species in A plot, 30 species in B plot, and 26 species in C plot have been found. 3) The kind which has the highest important value among the species located in naked plot(outside of Torreya nucifera forest) is Zoysia japonica and 18 other kinds were found. 4) The soil fertility through all depths are found higher in the forest soil than in that of open places. 5) P2O5, K, and total exchangeable bases etc. have shown the difference of contents according to the depth and generally had lower value as much as it goes down. 6) The content of N was a lot higher than any other forest soil and P2O5, K and total exchangeable bases seemed to be a little lower. 7) The overall flora of Todo consists of 71 species (9 species of wood plant and 62 species of herbs) added 28 kinds of non-reported species. 8) Themineral contents are the highest at a place of wind growth of Crinum maritimum which has much organic matter. The subsoil of this place is more fertile than surface soil. 9) The soil of Todo which is sandy soil, consists of shellfish shell and quartz, and has low fertility and alkali. 10) In the total occurrences of micro-organisms, bacteria was the greatest in number followed by actinomycete and fungi, in that order. 11) A survey of the soil depth and the ecological distributional pattern of micro-organismsm revealed that the number of micro-organisms is the greatest on the surface, gradually decreasing in proportion to the depth. 12) It was found that a comparatively greater number of micro-organisms occurred when the soil showed an adequate increase in water content.
