  • This study reports the identification of species of Colletotrichum strains originating from red-pepper and Chinese matrimony vine in Cheongyang. Ninteen isolates of red-pepper and 26 Coiletotrichum isolates of Chinese matrimony vine were compared with 5 isolates of strawberry representing C. gloeosporioides, by use of morphological and cultural criteria. Twenty three isolates among 26 isolates from Chinese matrimony vine were identified as C. acutatum, characterized by the low growth rates and the low sensitivity to carbendazim and diethofencarb. Also, all the isolates of red-pepper were identified as C. acutatum, showing the same characteristics as those of Chinese matrimony vine. Three and five isolates from Chinese matrimony vine and strawberry, respectively, were identified as C. gloeosporioides, characterized by the high growth rates and the high seneitivity to carbendazim and diethofencarb. There were differences in colony color and pathogenicity between Chinese matrimony vine isolates and red-pepper isolates of C. autatum. The isolates of C. acutatum from Chinese matrimony vine producing orange colored colonies with abundant spores showed the strong pathogenicity to Chinese matrimony vine, although they could not infect fruits of red-pepper by the wound inoculation. However, red-pepper isolates of C. acutatum producing gray colonies showed the strong pathogenicity to Chinese matrimony vine as well as red-pepper. Furthermore, comparative study on PCR amplification of ITS regions of rDNA was carried out using a number of Colletotrichum isolates. A species-specific primer could be used for the identification of C. acutatum from red-pepper and Chinese matrimony vine.

  • Wood-anatomical studies on vines, one of the main materials for fork craftworks used in the past, were insufficient compared to those for trees. Therefore, it is important to identify the species of vines in order to preserve the vinery craftwork relics. In this study, the species of 31 samples (30 traditional baskets and one sculpture relic) obtained from Korea were identified. Twenty-two baskets among 30 baskets were identified as Cocculus trilobus DC, a perennial vine which has flexible xylem and thick fibers in phloem. The other baskets were identified as $Lespedeza$ spp., a shrub with tough xylem. The sculpture part was $Actinidia$ $arguta$ Planch., a perennial vine with chambered piths.

  • Fragmentation due to land developments causes disturbances and changes of composition in forest vegetation. The purpose of the study was to develop the impact assessment model for quantitative distance or degree of disturbance by land developments. This study conducted a survey about structure and composition of forest vegetation to determine degree of impact from land developments. The results of field survey, there was a difference in structure and composition of forest vegetation such as tree canopy, herbaceous cover, and number of vine and alien species the distances from edge to interior area such as 0m, 10m, 20m, 40m, and over 60m. To assess the disturbance of forest vegetation, the factors selected were the rate of vine's cover and appearance of alien species. The impact assessment model about vine species explained by a distance, forest patch size, type of forest fragmentation, and type of vegetation ($R^2$=0.44, p<0.001). The other model about alien species explained by a distance, type of forest fragmentation, type of vegetation, and width of road (85.9%, p<0.005). The models applied to Samsong housing development in Goyang-si, Gyunggi-do. The vines and alien species in the study area have had a substantial impact on forest vegetation from edge to 20 or 40m. The impact assessment models were high reliability for estimating impacts to land developments. The impact of forest vegetation by development activities could be minimized thorough the adoption of the models introduced at the stage of EIA.

  • This study showed the current plantation of woody landscape plants of 42 school gardens in Daejeon metropolitan city. The ratio between evergreen tree and deciduous tree was 67% to 33%. The ratio between evergreen shrub and deciduous shrub was 48% to 52%. Also, 161 kinds of woody species were found; evergreen tree was 21 species, deciduous tree was 67 species, evergreen shrub was 16 species, deciduous shrub was 44 species, and vine and the others were 13 species. The proportion of native woody species was 61% (98 out of 161 species). 110 species were planted at the front garden area. In the mid-garden, 77 kinds of woody species were found. In the side garden, 95 kinds of woody species were found. In the rear garden, 92 kinds of woody species were found. The surrounding of play ground and outer area were planted 82 species. The first ranked evergreen tree was Juniperus chinensis‘Kaizuka’. And Deciduous tree, evergreen shrub, deciduous shrub, and vine showed Gingko biloba, Buxus microphylla var. koreana, Hibiscus syriacus, Wisteria floribunda, respectively. The school symbol of tree and flower was planted in 41 schools. The first rank plants of school symbol tree and flower were Pinus densiflora, Forsythia koreana and Rosa spp. Plant nameplate was found at 22 schools. The plant nameplate was used for 1∼10 species at 17 schools. In conclusion, plantation of landscape trees should be considered characteristic of each school area. In addition, school landscape should be planned distinction of a elementary school, a middle school, a high school, and a school for handicapped. School landscape should be considered carefully from functional, natural, educational environment and maintenance viewpoints as well as urban forest networking.

  • 본 연구는 소나무 모수림 시업지를 대상으로 시업에 의한 하층식생 비교 및 갱신 치수의 생장초기과정을 구명하고자 수행하였다. 조사구는 시업지 12개소(요형지 6개소, 사면부 6개소)와 대조구 6개소를 각각 설치하였으며, 각 조사구에 대해 식생조사 및 각 치수의 절간 높이를 측정하였다. 그 결과, 모수림 시업지의 하층에는 싸리, 산초나무, 광대싸리, 조록싸리, 국수나무 등의 관목성 식물과 억새, 가는잎그늘사초, 큰기름새, 맑은대쑥 등의 초본성 식물, 칡, 청가시덩굴, 마, 다래, 왕머루, 산딸기 등 덩굴성 식물이 상당수 이입하고 있었다. 특히, 덩굴성 식물은 요형지에서 대조구와 사면부에 비해 상대적으로 많은 양이 이입되고 있었다. 매목조사 결과, 소나무 갱신치수는 비피압목 3,175본/ha, 피압목 7,842본/ha으로 나타났으며, 요형지의 경우, 사면부에 비해 갱신치수의 발생 밀도가 매우 낮았는데, 이는 덩굴성 식물에 의한 영향으로 보여 이들 덩굴식물에 대한 구체적인 제거방안이 필요할 것으로 판단되었다. 또한 비피압목과 피압목의 절간생장은 꾸준히 증가하는 것으로 나타났으며, 특히 비피압목의 절간생장속도는 피압목에 비해 빠른 것으로 나타났다. 이는 갱신치수가 주변 식물과의 경쟁에서 이겨낼 능력을 갖추게 되면 급격한 생장을 이루는 것으로 판단되므로, 모수림 시업 초기에는 풀베기작업 등을 통한 집약적인 관리가 필요할 것으로 판단되었다.

  • A disease causing leaf blight and vine rot was recognized on kudzu plants (Pueraria lobata) in Korea since 1991. A species of Phytophthora has been repeatedly isolated from the infected leaves. Identification in species level of the Phytophthora sp. remained unsolved. An isolate, KACC 47616 originally collected from Manchon Park in Daegu, has been kept in our laboratory. In 2013, three new isolates, KACC 47617 and KACC 47618 from Yeongyang and KACC 47619 from Gunwi in Gyeongbuk province, were collected and examined to classify up to species level by characterizing morphology, response to temperature and phylogenetic relationship. On the basis of morphological characters such as the nature of hyphal swelling, sporangia and sex organs, absence of chlamydospore production, optimum temperature for mycelial growth, and internal transcribed spacer rDNA and cytochrome oxidase subunit 1 sequence analysis of the pathogen, the causal fungus of kudzu plant was identified as Phytophthora asiatica.

  • Questionnaire survey from 101 visitors and 77 specialists was carried out to establish the management plan on landscapes of the artificial structure constructed in valley within Bughansan National Park. When comparison was made between ground sill work structure and valley landscape, visitor group responded to the highest scores in valley landscape after planting of vine species in the bottom of the constructure, while specialist group responded to valley landscape after the removal of the constructure. When it made a comparison between revetment work constructure and valley landscape, visitor group responded to highest scores in valley landscape after planting of vine species in the top of the constructure, while specialist group responded to valley landscape after replacing concrete revetment by stone revetment constructure. When it made a comparison between fall work constructure and valley landscape, both groups responded to the highest scores in valley landscape after the removal of the constructure. According to the valley landscape analysis, artificial constructures built in water channel should be matched to adjacent landscape with the removal of concrete constructure. The slope of water channel should be considered to build fall work constructure.
