This study was conducted to develop revegetation methods for the restoration of the steep slopes by seed attached ripping net revegetation methods. In general, steep slopes with decomposed granite soils and ripping rock are easy to erode by precipitation and impossible to revegetate only using hydroseeding with core net mulching because of poor soil fertility. The Seed Attached Ripping Net Revegetation Methods(SALNRM) will be the most popular and sustainable methods to restore decomposed granite soils and ripping rock exposed slopes. The main results are summarized as follows; 1. The net size with $1.5cm{\times}1.0cm$ density was more suitable for growing plants, and increasing the ratio of the slow release fertilizer was better to make early coverage and to grow germinated plants. 2. The fertilizer bag made by the ratio of Peatmose : Vermiculite : Perlite : Quick release fertilize r : Slow release fertilizer = 10 : 2 : 5 : 3 : 4 (v : v) was the best for plant's growth. 3. According to the seed mixture experiments, even though not using foreign grasses, the SALNRM using native plants can make diverse plant composition. 4. The SALNRM will make same early ground coverage by only using native plants like using foreign grasses. The SALNRM would become the popular revegetation methods to restore decomposed granite soils and ripping rock exposed slopes in Korea.

Molecular characterization of different genotypes reveals accurate information about the degree of genetic diversity that helps to develop a proper breeding program. In this study, a total of 30 EST-based simple sequence repeat (EST-SSR) markers derived from trumpet lily (Lilium longiflorum) were used across 11 native lily species for their genetic relationship. Among these 30 markers, 24 SSR markers that showed polymorphism were used for evaluation of diversity spectrum. The allelic number at per locus ranged from 1 at SSR2 locus to 34 alleles at SSR15 locus, with an average of 11.25 alleles across 24 loci observed. The polymorphic information content, PIC, values ranged from 0.0523 for SSR9 to 0.9919 for SSR2 in all 24 loci with an average of 0.3827. The allelic frequency at every locus ranged from 0.81% at SSR2 locus to 99.6% at SSR14 locus. The pairwise genetic dissimilarity coefficient revealed the highest genetic distance with a value of 81.7% was in between L. dauricum and L. amabile. A relatively closer genetic distance was found between L. lancifolium and L. dauricum, L. maximowiczii and L. concolor, L. maximowiczii and L. distichum (Jeju), L. tsingtauense and L. callosum, L. cernuum and L. distichum (Jeju ecotype), of which dissimilarity coefficient was 50.0%. The molecular fingerprinting based on microsatellite marker could serve boldly to recognize genetically distant accessions and to sort morphologically close as well as duplicate accessions.

식물의 기공은 이산화탄소와 수증기가 대기와 식물 사이를 이동하는 통로로 광합성 및 증산작용과 밀접하게 연관되는 중요한 생리적 기능 형질이다. 본 연구에서는 낙동강변에 서식하는 초본 식물종을 대상으로 자생식물과 외래식물 사이에 기공 형질에 차이가 있는지 조사 분석함으로써 낙동강변 식물 군집 내 기공 형질의 변이 양상을 파악하고, 또한 외래식물이 성공적으로 정착하는 이유를 알아보고자 하였다. 조사 결과, 같은 신장 모양 기공 형태를 가진 외래식물과 자생식물의 경우 기공밀도, 기공지수, 기공크기에 차이가 없었고, 이는 외래식물의 성공적 정착에 비어있는 생태적 지위가 꼭 필요한 것은 아님을 시사하였다. 기공밀도는 잎의 두께와 음의 상관관계를, 잎건조중량(LMDC)과는 양의 상관관계를 보였으며, 잎면적비(SLA)와는 상관관계가 없었다. 신장 모양기공을 가진 식물은 모두 양면기공형 잎을 가지고 있었고, 아령 모양 기공의 밀도 및 크기가 신장 모양 기공보다 작았다.

제주지역의 화산회 토양에서 파종기(3월 27일, 4월 7일, 4월 17일, 4월 27일, 5월 7일, 5월17일, 5월 27일)에 따른 제주 재래수수의 생태반응, 사료수량성 및 사료가치를 구명하기 위하여 2000년 3월 27일부터 9월 6일까지 10일 간격으로 시험하였다. 파종기에 따른 출수기까지의 일수는 72일에서 42일로 파종기가 지연될수록 출수는 늦어지는 경향이었다. 초장은 4월 7일 파종에서 222.9cm로 큰 편이었으나, 그 이전의 조파와 그 이후로 만파 할수록 점차적으로 작아졌고, 5월 27일 파종에서 초장은 172.9cm였다. 경직경, 엽수도 초장의 변화와 비슷한 경향이었다. 생초, 건초, 단백질 및 TDN 수량은 4월 7일 파종에서 각각 48.0MT/ha, 12.0MT/ha, 1.0MT/ha, 5.3MT/ha로 가장 증수되었으나, 그 이전의 조파와 그 이후 만파에 따라 점차적으로 감소되어, 5월 27일 파종에서 생초수량 31.1MT/ha, 건초수량 5.9MT/ha, 단백질수량 0.7MT/ha, TDN 수량 3.1 MT/ha로 감수되었다. 파종기가 3월 27일에서 5월 27일로 지연됨에 따라 조단백질 함량은 $7.8\%$에서 $11.4\%$로, 조지방 함량은 $1.7\%$에서 $3.3\%$로, 가용무질소물 함량은 $34.1\%$에서 $40.4\%$로, TDN 함량은 $42.9\%$에서 $52.5\%$로 증가되었으나, 조섬유 함량은 $40.6\%$에서 $32.3\%$로, 조회분 함량은 $10.3\%$에서 $7.6\%$로 낮아졌다.

The manufacturing industries which played a major role in the rapid economic growth and industrialization of Korea in the late 20th century had considerable difficulties changing their manufacturing conditions from producer-oriented conditions to customer-oriented ones according to market changes. In this study, increase plant efficiency because grafts together modular system to plant layout and analyzes Work In Process(WIP) between product's cycle time and each process, family efficient plan wishes to choose opposite bank. Simulation approach used for presented methodology The effect will not gain the results for other reasons the inherent conditions of companies, people, and culture which have been hitherto described, but will be expected to help the direction for a new Lay-out production system to reflect on the native conditions rather than fixed technological means and methods in way of an analysis of fundamental problems which small and medium companies in Korea face.

Transformed hairy roots of Scopolia parviflora, producing tropane alkaloids and native to Korea, were obtained following infection of rhizome segments with Agrobacterium rhizogenes A4. Each root tip induced from inoculum sites excised and cultured in MS agar or liquid medium. About seventy of hairy root clones were established. Among them, several fast growing hairy root clones were examined for alkaliod content. Two dimensional TLC analysis showed that the tropane alkaloid pattern of hairy root was more complicated than that in the rhizome of mother plant. On the other hand, some hairy root clones did not produce scopolamine and hyoscyamine. In HPLC analysis, some hairy root clones yield higher levels of scopolamine and hyoscyamine than those of mother plant rhizome which used for infection. Scopolamine and hyoscyamine were identified by comparison of their retention times and of their spectra data with those of authentic compounds.

Cynanchum L. in the subfamily Asclepiadoideae (Apocynaceae) includes four recognized species on the Korean peninsula, two of which are native to South Korea. However, the species ranges in South Korea are poorly defined. During a field survey, we discovered C. thesioides, previously unrecorded in South Korea, in Gimpo-si, Gyeonggi-do, and found an additional population of C. chinense, for which only one population has been reported in South Korea. The two taxa are considered rare species with extremely restricted distributions in South Korea, especially C. thesioides. We provide fundamental information, including descriptions, images of the habitats and morphological characters, and a taxonomic key for identification and assessments of the conservation status of Cynanchum species in Korea.

Arctium tomentosum Mill. (Asteraceae), from Ulaanbaatar in the Khentei phytogeographical region of Mongolia, is recognized here as a new genus and species of the flora of Mongolia. Arctium differs from other genera of Asteraceae by the hooked apex of the involucral bracts. While A. tomentosum is most similar to A. lappa, it is easily distinguished by the glandular hairs of the corolla limb and the widened inner involucral bracts. Taxonomic notes, a description of the morphology, detailed photos, habitat information, the phenology and a distribution map of A. tomentosum are provided.
