Adenophora racemosa is recently reported as a new Korean endemic plant species. However, the phylogenetic relationship of this genus has been controversial due to the morphological similarity and frequent morphological change of aerial parts. To verify the phylogenetic position of Adenophora racemosa and phylogenetic relationship of genus Adenophora, we analyzed the internal transcribed spacer (ITS) sequence of nuclear ribosomal DNA (nrDNA) and random amplified polymorphic DNA (RAPD) using 21 individual of 6 Adenophora species, A. verticillata, A. divaricata, A. racemosa, A. remotiflora, A. stricata and A. tetraphylla. In comparative analysis of the nrDNA-ITS sequences, we could not found not only any species specific nucleotide sequence but also could not estimated their inter or intra species. In the phylogenic analysis based on the RAPD derived DNA polymorphism, Adenophora species were classified into four groups by clustering analysis of the UPGMA. These results suggest that the DNA fingerprinting based on RAPD is more suitable than nrDNA-ITS sequence for the phylogenetic analysis of Adenophora species.

This study was carried out to investigate vegetation structure and soil properties of Adenophora racemosa population distributed in Jeombongsan, Seoraksan, Odaesan and Dutasan in Gangwon-do, Korea. From August 2007 until September 2009, $2m{\times}2m$ quadrate was established in native area of Adenophora racemosa in order to record a dominants and coverage, and soil factors at 22 sites. It was found that the altitude in the distributed areas for Angelica gigas population was 800 m or more. Adenophora racemosa population was classified into Rhododendron mucronulatum dominant population, Geranium var. hirsutum dominant population, Caret siderosticta dominant population and Aruncus dioicus var. kamtschaticus dominant population. In the site of study, soil pH, electrical conductivity, soil organic matter, available phosphorous, and exchangeable potassium, exchangeable calcium, exchangeable magnesium, exchangeable sodium concentration and total nitrogen were ranged from 5.0~7.1, 0.06~0.65dS/m, 0.96~8.94%, 12.3~32.8mg/kg, 0.12~0.89cmol+/kg, 0.34~10.08cmol+/kg, 0.1~l.4cmol+/kg, 0.02~0.29cmol+/kg and 0~8.4% respectively. According to the results of DCCA, Adenophora racemosa population were distributed in the high available phosphorous and exchangeable potassium, and Rhododendron mucronulatum dominant population was situated on low available potassium and high slope degree, Geranium var. hirsutum dominant population was high altitude, electrical conductivity and exchange magnesium, and Carex siderosticta dominant population and Aruncus dioicus var. kamtschaticus were distributed on high total nitrogen, organic matter, available phosphorous.
