  • Saussurea nipponica subsp. higomontana was recorded first from Mt. Mudeung-san, Gwangju-si, Korea. We named the plant Mu-deung-chui. It had been considered as an endemic plant to Japan. S. nipponica sensu lato is the one of the most famous polymorphic species which consists of 7 infraspecific taxa (subspecies) isolating geographically. Among them, S. nipponica subsp. higomontana is distributed on high mountain regions of Kyushu and Shikoku.

  • This study was investigated to find out the distribution of flora and remarkable plants and factors and management measures for influx of wild disturbed plants in the Damyang area of Mudeungsan National Park. The field survey was carried out 8 times from May 2019 to October 2020. First of all, in the Damyang area of Mudeungsan National Park, a total of 603 taxa in 107 families, 349 genera, 531 species, 57 varieties, 5 subspecies and 10 forms. This result was found to be about 12.33% of the total 4,881 taxa of vascular plants in Korea. In addition, Rare plants were classified as 15 taxa. Floristic special and Korean endemic plants were identified as 85 taxa and 13 taxa, respectively. Lastly, the naturalized plants that appeared in the Damyang area of Mudeungsan National Park were observed in 45 taxa with 45 species of 16 families and 36 genera. Moreover the naturalization rate was 7.46% and the urbanization index was calculated to be 14.01%. The wild disturbed plants were found in a total of 4 taxa. Especially, a sheep sorrel(Rumex acetosella) was focused on managing for physica and biological control at Sinseondae Eoksaepyungjeon.

  • In order to observe the anatomical phenomena of root formation in the hypocotyl cuttings of maples, the hypocotyls of Acer palmatum. Acer micro-sieboldianum, and Acer saccharinum were used as the materials. The rooted portions were sectioned by a microtom and doubly stained by safranin and fast green. The results obtained are summarized as follows; 1. A cross section structure of hypocotyl cuttings of Acer sp. is consist of epidermis, cortex, vascular bundle and pith from the outside. The vascular bundle makes circular shape forming polyarch in A. saccharinum and tetrarch in both A. palmatum and A. micro-sieboldianum. 2. An adventitious root of A. saccharinum originated in phloem parenchyma, while that of A. palmatum and A. micro-sieboldianum originated in interfascicular parenchyma related with phloem cells. 3. The hypocotyl cuttings of Acer sp. is commonly composed of parenchyma tissue having vigorous differentiation capability. Therefore, the originated root grow easily through the cortex and epidermis breaking their tissues.
