  • Laboratory experiments for the removal efficiency of heavy metals in land application of sludge, the accumulation and translocation of heavy metals in x plants after transplanting, and the responses of Minari growth with different ratio of land application of sludge were conducted to determine the potential ability of bioremediation with Minari plants. The removal rate and translocation of copper. zinc. lead. and cadmium in soil and plants were compared after transplanting the Minari plants to soil treated with different ratio of sludge. The removal efficiency of heavy metals in soil incorporated with sludge was different with application ratio, but increased with growing periods of Minari plants. The removal efficiency of Cu, Zn, Pb, and Cd ranged from 67 to 74% from 51% to 63%, from 37% to 71%. and from 15% to 25% after 45 days of transplanting. respectively. The amount removed the copper value. 65.9 mg/kg, observed to be highest in soil incorporated 3% sludge after 45 days. The translocation of Cu. Zn. Pb. and Cd from shoots to roots ranged from 18 to 53%, from 17 to 32%, from 14 to 49%, and from 23 to 38% over growing periods. respectively. In plant responses it appeared to be inhibited the plant growth in the treatment compared with the control at early stage of growth. However, the fresh weights of Minari plant increased from 12.5 to 62.5% in the sludge application after 45 days relative to the control. Therefore the Minari might play a useful role in bioremediation of Cu, Zn, Pb, and Cd in the land application of sludge.

  • This scientific study was carried out to investigate the flora of Jecheon, located in the middle part of the Korean peninsula. We have surveyed the vascular plants of the above region from March to October 2014 (18 times). Totally, we identified 765 taxa; 127 families, 411 genera, 678 species, 9 subspecies, 70 varieties, 6 forms, and 2 hybrids. Endangered species designated by the law called' Protection Law for Endangered wild fauna and flora' were 6 taxa. The red data of vascular plants according to IUCN valuation basis comprised 29 taxa; 21 families, 26 genera, 29 species. 25 taxa were considered to be endemic to Korea. The floristic regional indicator plants found in this region were 122 taxa in total. Among them 12 taxa revealed the floristic degree V, 13 for floristic degree IV, 34 for floristic degree III, 11 for floristic degree II and 52 for floristic degree I. The naturalized plants were identified as 58 taxa. Further, we anticipate that the findings of this study survey would be useful for the scientific community to gain capacity to identify and conserve vascular plants of the region.

  • Endophytic fungi are present in host plants and contribute to resistance to biotic and abiotic stress. Aquatic plants are living in aquatic environment such as saltwater or freshwater and exposed more water stress than other land plants. In this study, we investigated 4 wetlands in Jeju and collected 11 aquatic plants. Exogenous microbes were removed by preprocessing of plants and endophytic fungal strains were isolated from the plants. We isolated 126 fungal strains from Namsaengi-pond, 22 fungal strains from Sujangdong-marsh, 44 fungal strains from Yongsu-reservoir and 32 fungal strains from Gangjeongcheon. The fungal strains were identified using internal transcribed spacer (ITS) region and analyzed the phylogeny and diversity. Endophytic fungi isolated from plants of Namsaengi-pond were classified to 30 genera, 19 families, 12 orders, 7 classes and 4 phyla. Endophytic fungi of Sujangdong-marsh were classified to 11 genera, 11 families, 6 orders, 5 classes and 4 phyla. Endophytic fungi of Yongsu-reservoir were classified to 13 genera, 12 families, 7 orders, 5 classes and 4 phyla. Endophytic fungi isolated from Gangjeongcheon were classified to 9 genera, 7 families, 5 orders, 2 classes and 1 phyla. Overall, they were divided 40 genera and Alternaria, Colletotrichum and Fusarium were isolated from 4 sites in common. By investigating the endophytic fungi in aquatic plants, it is for baseline data that determination of diversity and the ecological distribution of endophytic fungi.

  • Six field surveys were conducted at 29 locations from April 2020 to April 2022 to identify the freshwater flora of the Taean Peninsula. Based on the collected specimens, the vascular plants of the Taean Peninsula were summarized as 391 taxa: 94 families, 248 genera, 362 species, 5 subspecies, and 24 varieties. Freshwater plants in the Taean Peninsula consisted of 104 taxa, 45 taxa for aquatic plants, and 59 taxa for wetland plants. When classified by life history, annuals accounted for 33 taxa, winter annuals 5 taxa, biennial 6 taxa, and perennials accounted for most of the 60 taxa. Among the 391 identified taxa, 2 taxa of Endangered plants, 3 taxa of Korean endemic plants, 5 taxa of IUCN red list plants, 49 taxa of Korean floristic target plants, 38 taxa of biological resources subject to the approval of outbound transfer, 55 taxa alien plants and 7 taxa of ecosystem disturbing plant. The results of this study are intended to be used as basic data on the freshwater environment and distribution of aquatic plants in the Taean Peninsula.

  • Background: In 2020, a categorized list of wetland preferences, major habitats, and life forms of 4145 vascular plant taxa occurring in the Korean Peninsula was published by the National Institute of Biological Resources. We analyzed the list and explored the distribution patterns of the five categorized groups according to wetland preference, along with the information on the major habitats and the life forms of the plants belonging to those categories. Results: Out of 4145 taxa, we found that 729 wetland plant taxa (18%) occur in Korea: 401 obligate wetland plants and 328 facultative wetland plants. Among the 729 wetland taxa, the majority (73%) was hygrophytes and the remaining 27% was aquatic macrophytes. Furthermore, almost all of the wetland taxa are herbs; so, woody plants are only 4.7%. The 16 carnivorous taxa distributed in Korea were characterized as obligate wetland plants. Conclusions: We expect the categorized information would promote understanding of the characteristics of the plant species and would be an important source for understanding, conservation, and restoration of wetland ecosystems.

  • An unrecorded Ceriporiopsis species was collected at Mt. Gariwang, Gangwon Province, in 2008. Based on morphological characteristics, such as a fully resupinate basidiocarp, a reddish white to pinkish poroid hymenophore and a monomitic hyphal system with clamp connections, the species was identified as Ceriporiopsis resinascens. This is the first report of Ceriporiopsis resinascens in Korea. We confirmed the identity of the species as Ceriporiopsis resinascens based on ITS sequence analysis.
