劉在殷 명지대학교 1979 明大論文集 Vol.12 No.-

The convenient method in storage of chestnuts has been studied to use easily for the producers and the consumers. In this paper the protected chestnuts which stored underground were tested on the effective method of the long-term storage on a ground of their species, kinds of treatment and terms of treatment. The results obtained from the above methods are summarized as follows: 1. All the species can be stored for 10 months but changed slightly in qualities. 2. The effects of storage are very significant by their species, kinds of treatment and terms of treatment, respectively. 3. The chestnuts which dried in the shade for 1 and 3 day’s have been storaged with the best condition. 4. The control of germination during the long-term storage is not discussed in this paper.

兪在殷 명지대학교 1978 明大論文集 Vol.11 No.-

The purpose of this study is to investigate the effects of various hastening germination treatments to overcome seed dormancy in Macrocarpium officinale Nakai. The seed were collected on September 20. 1977. in Cheong Yang Province. For the purpose of this study, germination percentage and germinative energy obtained from various hastening germination treatments were analysed. 1. The results may be summarized that almost high differences in the germination percentage and germinative energy of the seeds among various hastening germination treatments are observed. 2. The cause of ungermination are considered that it controls of water obsorption by seed-coat.

금번 필자는 1987년 7월 5일부터 12일까지 8일간과 1989년 9월 11일부터 17일까지 7일간 총 15일 동안에 속리산 국립공원 일대의 자원식물 분포상을 조사하여 다음과 같은 결과를 얻을 수 있었다. 금번 조사기간 동안에 확인된 속리산 지역의 자원식물은 총 120과 369속 516종 1아종 88변종 및 7품종의 612종류였다. 이중에는 74종류의 식재 및 재배종이 포함된다. 속리산 지역에서 가장 흔히 볼수 있는 상층목으로는 소나무, 신갈나무, 졸참나무,서나무 등이고 하층목으로는 당단풍,쇠물푸레,쪽동백,생강나무 등이 주종을 이루고 있다. 남방계 식물인 노각나무는 이곳이 북한계가 아닌가 생각되며, 회화나무가 자생하고 있는 것을 확인할 수 있었던 것도 하나의 의미 있는 일이다. The distribution of resources flora in Mt. Sokri had been studied by releve method from July 5 to July 12, 1987 and from Sep. 11 to Sep 17, 1989.171 places with square (15m × 15m) were selected for exact survey and all the species which were present in the area were recorded. The results obtained can be summarized s follows; 612 taxa of vascular plants weredistributed in surveyed area of Mt. Sokri, which included 120 families, 369 genera, 516 species, 1 subspecies, 88 varieties and 7 forma. Among them, 74 species which had been cultivated or planted were also included. The upper layer plants was mostly occupied by Pinus densiflora, Quercus mongolica, Quercus serrata, Quercus variabilis and Carpinus laxiflora. In other hand, Acer pseudo-sieboldianum, Fraxinus sieboldiana, Styrax obassia, and Lindera obtusiloba were main species which composed of lower layer plants in Mt. Sokri. It was implicated that Mt. Sokri is the Northem limit of Natural habitats of Sophora japonica in Mt. Sokri in spite that they are usually occurring in cultivated area or field.

茶나무의 生育北限界

인간사회의 뛰어난 기호품으로서 성인병예방, 암발생억제, 중금속해독 등의 효과가 연구 발표되고 있는 이유로 녹차수요가 증가하고 있는 오늘날, 우리나라에서의 차나무 생육 분포지의 현황 및 재배지의 확대 가능성을 찾아보기 위하여 1998년 2월부터 2000년 8월까지 현지를 답사 조사하여 다음과 같은 결과를 얻을 수 있었다. 1.현재까지 알려진 차나무의 생육 분포지 북한계는 북위 35˚43'지점의 전북 김제군 금산면 금산사로 알려졌지만 금번 조사에서는 이보다훨씬 북쪽으로 북위 37˚25'지점의 인천광역시 연수구 옥련동과북위 37˚35'지점의 서울시 동대문구 청량리동임을 알 수 있었다. 2.인천이나 서울의 연평균기온이 11.3℃및 11.6℃이고, 1월중 평균 기온이 -3.2℃및 -3.5℃로 차나무의 생육환경으로는 부적당하다고 알려져 왔지만 생육하고 있음으로 보아 차나무의 내한성 범위가 상당히 크다고 볼 수 있다. 3. 차나무의 내한성 범위가 상당히 크다고 감안 할 때 내한성 품종을 선발하고 생육환경을 좀 개선시킨다면 차나무의 생육 분포지나 재배지를 현재 보다 상당히 북상시킬 수 있으리라고 여겨진다. Thea sinensis has been used as a green tea and known for its various effects such as prevention for geriatric diseases and tumorgenesis, and counterpoisoning the toxic effects by heavy metals. Because the demand for the green tea is increasing, the arable land for Thea sinensis in Korea had been studied from February of 1998 to August of 2000. The conclusions obtained were summarized as follows. (1) The latitudinal limit of the margin of Cultivation for Thea sinensis has been known as Keumsan temple, Keumsan-Myon, Kimje-Gun, Chunbuk, Korea located in north latitude 35˚43'. However this studies revealed that that sinensis could be grown at the far northern part of Keumsan temple such as Okryon-Dong, Yeonsu-Gu, Incheon and Cheonyangri-Dong, Dongdaemun-Gu, Seoul, which are located at 37˚25'and 37˚35'north latitude, respectively. (2) The annual and monthly average temperature of Incheon and Seoul has been recorded between 11.3˚ and 11.6˚, and -3.2˚, respectively. These cold environments was thought as one of the major limitations for Thea sinensis to be cultivated, however through this study it was concluded that Thea sinensis was able to endure the cold in a broader range than that of evaluated. (3) Considering the ability of the enduring the cold of Thea sinensis, it is expected that the arable land for the Thea sinensis could be broaden into the northern land by developing cold-resistant species and cultivation environments.

한반도식물대(韓半島植物帶) 판별을 위한 표준종(標準種)에 관한 연구

유재은,백승언,김재수 명지대학교 자연과학연구소 2006 자연과학논문집 Vol.25 No.-

본 연구는 한반도의 삼림식물대 판별을 보다 더 쉽게 하고저 함에 주안점을 두고 연구하였다. 필자의 한사람인 白(2002)이 구분해 놓은 9개의 식물대를 기초로 하여 그 안에 있는 고유수종(固有樹種)과 각 식물대(植物帶) 안에서 분포의 남한계(南限界)와 북한계(北限界)를 이루는 수종을 찾아내어 한 쌍씩의 수종을 조합(組合)하여 복합표준종(複合標準種)으로 삼고, 그 상재도(常在度)를 계산하였으며 각 식물대의 적합도(適合度)를 비교하여 그 결과를 표 7에 표시하였다. 복합표준종의 선정은 각 산악의 단위구간내(單位區間內)에 공존하는 수종을 가지고 선정하였다. 이들 고유수종과 복합표준종에 의하여 보다 더 상세하고 구체적인 식물대(植物帶)의 적시(摘示)가 가능해졌다고 여겨지며, 이미 白(2002)의 연구에서 얻어진 판별식과 병용할 때에는 더욱더 정밀한 식물대의 판별을 할 수 있을 것으로 여겨진다. Selecting a proper indicator species is prerequisite for an efficient discrimination of plant zone in a certain geographical area. To select an indicator species applicable in the Korean Peninsula, the plant zone of the Korean Peninsula was divided into nine. In each plant zone, endemic species were surveyed, and the northern and southern boundary species were studied. The various combinations of northern and southern boundary species were used as compound indicator species and their applicability to distinct the plant zone in the Korean Peninsula were compared by analyzing their presence in each plant zone. The species existing together in the unit area of the mountains were selected as the compound indicator species. From the analysis, it was concluded that more detailed and concrete description for each plant zone was accomplished by the combinatorial application of edemic species and the compound indicator species. Thus it is expected that this improved method can be efficiently used to discriminate the plant zone in the Korean Peninsula.
