Objectives : The purpose of this study is to analyze the origin plants, the habitat and the characteristics of the origin-plants of the medicine herbs belong to Araceae. Methods : To achieve the purpose of this study 48 bibliographies about 4 kinds of herbs belong to Araceae were examined. The examination was focused on the origin plants, habitat, the efficacy. Standing on this analysis the list and characteristics of the origin-plants were presented. Results : The results indicated that 1. In the original plants of 4 kinds of herbs, there were 27 species of scientific name totally, 25 species belonged to Araceae, and 2 species didn't. The origin plants of Pinelliae rhizoma were 3 species of different family plant, 16 species for Arisaematis Rhizoma, 2 species for Typhoni Rhizoma, and 6 species for Acori Graminei Rhizoma. 2. In the view of its authenticity, there was one kind of genuine species, 2 species of substitutes in the origin plants of Pinelliae Rhizoma, 14 kinds of genuine species, 2 species of substitutes in the origin plants of Arisaematis Rhizoma, and Whole origin plants of Typhoni Rhizoma, Acori Graminei Rhizoma were genuine species. 3. According to the habitat, there were 15 species distributed in Korea, China and so on. And 16 species were distributed in Korea, 25 species were of foreign origin. 1 species was unknown. 4. The each efficacy of origin plants were reported in the main subject Conclusions : Among the 4 medicinal herbs in the commonly using family Araceae, there were 27 origin plants(25 species belong to Araceae, and 2 species doesn't), so the number of origin plants are almost 6.75 times compared with the cases of the herbal name. Also, according to the habitat, approximately 59.3% of origin plants were producted in Korea, and approximately 92.6% of origin plants were of foreign origin.

A fluorescent material was accumulated in inoculated leaves showing necrotic local lesions of tobacco plants with N gene, Nicotiana tabacum cvs. Xanthi-nc NN, Samsun NN, Burley 21 and KF 114, and N. glutinosa, and Datura stramonium at the early growth stages by the inoculation of Tobacco mosaic virus (TMV). It was identified as a coumarin phytoalexin, scopoletin. Although the material was most prominently produced in TMV-inoculated tobacco leaves with local necrotic lesions, its accumulation was also noted in uninoculated leaves of TMV-inoculated plants. Its accumulation was somewhat greater in high resistance-induced leaves than low resistance-induced and intact leaves. Scopoletin treatment induced the expression of a pathogenesis-related protein, PR-1, prominently at the concentration of 500 or 1000 ${\mu}$g/ml. This suggests that scopoletin is a phytoalexin abundantly accumulating in N gene-containing resistant plants in response to TMV infection, and may be related to hypersensitive responses (HR) and systemic acquired resistance (SAR) in the resistant tobacco plants.

Following recent taxonomic, distributional, and nomenclatural revisions, an updated checklist of endemic plants on the Korean Peninsula is needed. This study provides an updated checklist of vascular plants endemic to the Korean Peninsula and describes their distribution within administrative provinces. The revised checklist includes 373 endemic taxa (304 species, six subspecies, 49 varieties, and 14 nothospecies) from 179 genera and 64 families, representing 9.5% of the total native flora of the Korean Peninsula. Asteraceae (41 taxa), Ranunculaceae (29 taxa), Liliaceae s.l. (24 taxa), and Rosaceae (22 taxa) were the most widely represented families. Compared with the most recent checklist published in 2017, 39 taxa were excluded from the checklist; one taxon was excluded because it did not have a valid published name, seven taxa were excluded because their natural habitats extended to neighboring countries, four taxa were excluded because they were treated as a rank form, and 27 taxa were excluded because they had been identified as heterotypic synonyms of taxa distributed outside of the Korean Peninsula. Fifty-two new taxa were included based on the literature. This checklist will help to focus conservation efforts and provide a framework for research, protection, and policy implementation related to these endemic taxa.

Soswaewon as a typical villa garden of Korea is a symbolic garden that its diverse compositions imply a specific meaning. This study reviewed the purpose of introduction, meaning, and location of the landscape plants as one of the compositions and covering quite a large part of Soswaewon through 48 Yeong (meaning 48 poems of Soswaewon) and Soswaewondo (meaning Map of Soswaewon). In 48 Yeong, 27 verses describe landscape plants as their key poetic matters. The most frequently mentioned top 3 plants are bamboos, pine trees, and Japanese apricots. The three plants are called Sehansamwoo(歲寒三友) showing constant fidelity and loyalty in any changing situations, which was regarded to represent the nature of scholars. And also the study examined the frequency and planting location of the plants in Soswaewon by comparing 48 Yeong and Soswaewondo, and the result showed some differences between them. That seems to be caused by the limitations in the comparison, because in case of 48 Yeong, the location and frequency of landscape plants can be examined only through the context of the verses, and Soswaewondo showed different production time from 48 Yeong and expressed them only in a form of drawing. The plants have symbolic meanings multi-layered and ambiguous. With their symbolic meanings, the landscape plants reviewed through 48 Yeong consistently represent fidelity and loyalty, man of virtue, and hermit. That is, Soswaewon is the garden granting some significance to its compositions by interacting with the things.

The purpose of this study is to offer the flora data for conserving the biodiversity of Gyeongju National Park by objective surveying and analysing the flora distributed in Mt. Gumi District, Gyeongju National Park, South Korea. The flora of Mt. Gumi were surmmarized as 476 taxa including 97 families, 297 genera, 419 species, 3 subspecies, 46 varieties and 8 forms. The rare plants were 6 taxa such as Aristolochia contorta, Paeonia lactiflora var. trichocarpa, Potentilla discolor, Berchemia berchemiaefolia, Trigonotis icumae and Iris odaesanensis.

The specific plants by floristic region were 38 taxa such as Salix chaenomeloides(I), Hylomecon vernalis (I), Oxalis obtriangulata (I), Viola orientalis(II), Adoxa moschatellina (II), Cirsium chanroenicum (II), Vitex negundo var. incisa (III) and so forth. The naturalized plants were 36 taxa such as Fallopia dumetorum, Chenopodium album, Lepidium virginicum, Amorpha fruticosa, Euphorbia supina, Carduus crispus, Erigeron strigosus, Festuca myuros and so forth.

Sweet potato infected with a viral disease (SPFMV) showed irregular chlorotic patterns, so called feathering associated with faint or distinct ring spots that have purple-pigmented borders. SPFMV was eliminated from sweet potato plants using meristem tip culture. MS medium supplemented with BAP (2mg/L) and NAA (0.05 mg/L) was used for shoot proliferation and 1/2 MS medium for rooting of the plants. Highest percentage of regenerated plants (60%) was obtained from the optimum size (0.3-0.5mm) meristem tips. Of these, 60% plants were found negative for SPFMV by RT-PCR. Virus detection by RT-PCR was found to be a reliable method. Meristem-tip culture to produce SPFMV-free quality sweet potato and virus detection by RT-PCR is an efficient, time saving and reliable method for production of SPFMV-free tissue culture raised plants.

In July 2019, damping-off symptoms of young Fischer's ragwort (Ligularia fischeri) plants were observed in four vinyl greenhouses of a farmer located in Taebaek, Gangwon Province, Korea. This disease occurred in 20-30% of plants in the vinyl greenhouses investigated. Nine isolates of Rhizoctonia sp. were obtained from the diseased plants. All the isolates were identified as Rhizoctonia solani AG-2-2 (IIIB), based on morphological, cultural characteristics, and anastomosis test. Three isolates were used for artificial inoculation test on Fischer's ragwort. Pathogenicity of these isolates was confirmed on the plants with the inoculation tests. Damping-off symptoms observed on the inoculated plants were similar to those observed in the diseased plants in the vinyl greenhouses. This is the first report of R. solani AG-2-2 (IIIB) being the causative agent in damping-off in Fischer's ragwort.
