  • The objective of this study was to determine the optimal amount and the mixture ratio of seeds for revegetation species by investigating their growth characteristics. For the purpose of the experiments, 15 plants were chosen. In May of 1995 to September of 1998, the nursery seedbeds of the College of Agriculture and Life Sciences, Seoul National University were seeded with the mixtures of those species. Then, the nursery seedbeds were treated to investigate the effects of the amount of seeding, the amount of fertilizer, and the depth of soil on the growth characteristics. As the results of the experiments, it was found that the effects of all the treatments on growth of shoots and roots were significant in the early phase. For the expected number of seedlings more than 3,000 per square meter, many seedlings got withered to death while the survivors were suppressed to grow slow in the early stage due to the density problem.

  • 우리나라에서 개미가 종자를 분산시키는 식물종과 그 종자의 특성을 밝히고자, 2012년 4월부터 2013년 10월까지 열매 수집, 전파체 특성, 관련된 개미종을 조사하였다. 개미가 종자를 퍼뜨리는 엘라이오솜을 종자에 부착한 8종의 식물을 추가로 확인하였다. 종자에 부착된 엘라이오솜의 형태는 종마다 형태나 크기가 매우 다양하였다. 전파체를 물어가는 개미종은 곰개미, 곰뿔개미, 누운털개미, 주름개미, 긴호리가슴개미, 고동털개미 등 6종이었으며, 일본왕개미나 몸집이 작은 사쿠라개미 등은 전파체를 물어가지 않았다. 이러한 결과는 여름철에 개화하는 식물종도 개미와 엘라이오솜을 매개로 하는 상리공생함을 확인하였다. 앞으로 개미가 종자를 퍼뜨리는 자생 식물종을 파악하기 위한 많은 연구가 필요하다.

  • Background and Purpose : To investigate the wild plants to be used for survival on tactical activity of Special Forces soldiers at deep enemy's territory Material and Methods : To investigate the wild plants, I selected various native plants in the forests and fields that can be used for medical cure and eatables. And I selected some poisonous plants and some plants containing water or salts, after due consideration of tactical activity and use in the battle-fields. Results and Conclusion : There are many wild plants to be used for multiple purpose in our country. We can get from these plants emergency medicines, foods, even water and salts. I chose 6 species of digestives, 11 species of analgesics, 9 species of antiphlogistics, 7 species of hemostatics, 5 species of antidiarheal, 5 species of diuretics, 2 species of laxatives, 7 species of antipyretics, 1 species of vermicide and 45 species of eatable plants and 12 species of poisonous plants. and I summarized general name, scientific name, component, picking season, used portion, taking method of these plants. Building up accurate knowledge on the wild plants could contributed to raise survival rate of Special Forces soldiers in the battle-fields.

  • This study aimed to address problems and suggest solutions in applying seed mixture design criterior of slope revegetation works according to the "Slope revegetation design and guidelines(proposed)" proposed by the Ministry of Construction and Transportation. To do this, a proper thickness of attaching soil media was identified in April experiment where the thickness and slopes varied. The results were as follows. In the test, the coverage rate of plot where exotic grass was not sowed increased with time and was 79.3% after three months of seeding, which indicated less risk of soil erosion. When applying the provisional standards of the plant mix proposed by the Ministry of Construction and Transportation, tree seeds and native plants were found ill in the early stage in all test lands due to exotic grass. This was because exotic grass which grew well in the early stage, could grow densely, so it might hamper the growth of other plants. When slope revegetation were planted and goals were set for herb, shrub and tree dominant mixture types, it was required to shift focus toward nursing up native plants first rather than early plantation of exotic grass.

  • Focusing on native plants that have a high possibility of being introduced as extensive rooftop material, this study was conducted to realize extensive and easy-to-manage rooftop gardens and to raise the utilization of native plants by verifying their growing response to soil media and depth. Its result is as follows: 1) In the case of Chrysanthemum zawadskii, the top growth was better in sandy loam than in P$_1$V$_1$P$_2$, and P$_1$V$_1$P$_3$, but the mortality rate was high, making it unsuitable soil. Regarding soil depth the mortality rate was lower in 10cm than in 5cm, and it grew well in 10cm. When using it for rooftop gardens, it would be desirable to keep the minimum viable soil depth over loom. 2) In the case of Sedium middendorffianum the mortality rate was 0% regardless of soil media and depth making it very suitable material for rooftop garden. Although the flowering rate was somewhat lower in P$_1$V$_1$P$_2$, and P$_1$V$_1$P$_3$ than in sandy loam, the mortality rate was low and the root growth was good. Therefore, provided that fertilizing is managed well, it is a plant that can be highly utilized. 3) In the case of Allium senescens, the mortality rate was 0% regardless of soil or soil depth, making it a very suitable plant for extensive rooftop gardens. Although top growth was poorer in P$_1$V$_1$P$_2$, and P$_1$V$_1$P$_3$than in sandy loam the root growth was good. Therefore, provided that fertilizing is managed well, it is a plant that can be highly utilized. In conclusion the study revealed that suitable species for extensive rooftop gardens are Sedium middendorffianum and Allium senescens. However, Chrysanthemum zawadskii can be utilized greatly when fertilizing is managed regularly in artificial mixed soil over l0cm.

  • Naturalized populations of two alien plants were newly found, and we describe their morphological characteristics and habitats with photographs. One is a member of Juncaceae, Juncus torreyi Coville, and was newly found at a pool of a beach in Gangwon-do. This rush is native to North America and belongs to the sect. Ozophyllum (subgen. Juncus) according to certain morphological characteristics, such as its racemose inflorescence, the absence of floral bracteole, and unitubular leaves with perfect septa. J. torreyi is easily distinguishable from Korean rushes by its long rhizomes with swollen nodes and globular head with 25-100 flowers. Its introduction into Japan and Europe was reported, but the ecological risk associated with its over-dispersal is not known. The other alien plant is a submerged plant, Egeria densa Planch. (Hydrocharitaceae), which was found in streams in Gyeongsangbuk-do and ditches in the Busan-si area, both of which being in the watershed of the Nakdong River. Egeria densa is similar to Hydrilla verticillata (L.f.) Royle, which is native to Korea. However, it is distinguished from H. verticillata by its larger flowers and lack of overwintering organs. This alien plant is native to South America and was introduced for aquarium gardening and naturalized around the world. Egeria densa is treated as a malignant weed due to its asexual reproduction and rapid growth. Size changes and the number of populations of E. densa must be investigated.
