In order to use as a new functional food material, we analyzed the chemical components including the organic compounds, minerals and Vitamin C of cherry and acacia honey which were produced in South Korea. The condensed rate of methanol extraction in honey was 87.51% of cherry honey and it was 93.06% of acacia honey. In the case of cherry honey, main organic compounds that extract by organic solvents in GCMS analysis were trichloromethane, propylcarbinol, methacide, cyclopentane, tetrafinol etc. and main aromatic compounds that extract by organic solvents in SPME analysis were formyl trichloride, propanal, furfurylaldehyde, pyrazole, benzenecarbonal etc. Also, in occasion of acacia honey, main organic compounds were trichloromethan, Acetoxyethane, Hexanaphthene, acetidin etc. and main aromatic compounds were Hydrazomethan, Azulene, Cyclotrisiloxane, Hydrazine etc. Proximate composition was crude protein 0.33%, crude fat 0.15%, crude ash 0.47% in cherry honey and crude protein 0.10%, crude fat 0.44%, crude ash 0.06% in acacia honey. Free sugar that analyze by HPLC was fructose 37.05%, glucose 27.29%, total sugars 64.34% in cherry honey and fructose 48.52%, glucose 24.29%, total sugars 72.81% in acacia honey. Vitamin C was not detected in two sample honeys. Minerals by ICP analysis were detected total 25 kinds in cherry honey, K 9.762 ppm¤Si 5.628 ppm ¤Na 5.096 ppm¤Ca 2.224 ppm etc. and total 22 kinds in sacacia honey, Na 4.527 ppm¤Si 3.420 ppm¤K 3.091 ppm¤Zn 1.482 ppm etc.

The coastal vegetation was classified by the Braun-Blanquet's phytosociological scheme and physicochemical properties of soil was also determined at the salt marsh of Mankyung and Dongjin river estuary. The vegetation of these areas was classified with 8 communities as followes Suaeda japonica, salicornia herbaceae, Phragmites longivalvis, Carex scabrifolia, Zoysia sinica, Aster tripolim, Suaeda asparagoides and Phacelurus latifolia community. Especially the zonations an annual and biennial halophytes were highly affected by surface soil.

The nutrient removal-capacity of four major dominant species distributed in Namchang-chon polluted with livestock wastewater and Samhyang-chon polluted with industrial and domestic wastewater were investigated. Water qualities and soil properties of three polluted sites were a quite different in concentration of nitrogen, SS and Ga. Dominant species in livestock wasetewater were Persicaria thunbergii, Zizania latiforia, Phragmites communis and Oenanthe japanica, those in industrial and domestic were Phragmites communis. Changes of NO₃-N, NH₄-N and P concentrations of culture solution are high in cultivor of Zizania latiforia and Oenanthe japanica. All four species removed NO₃-N most effectively. In experiment used directely polluted water from three areas ; all species from livestock wasetewater uptaked NO₃-N effectively. Phragmites communis from domestic, and Persicaria thunbergii and Oenanthe japanica from industrial and domestic wasetewater removed NH₄-N effectively. All species cultured in industrial waserewater removed P well, and Phragmites communis and Persicaria thunbergii cultured in domestic wastewater removed it moderately.

덕유산 아고산대 스키코스 주변 이식 침엽수의 수분상태

강상준,곽애경 충북대학교 과학교육연구소 2002 과학교육연구논총 Vol.18 No.1

본 연구는 1997년 6월 15일과 16일에 국립공원 덕유산 향적봉(1,614m) 산록 무주리조트 국제스키코스 지역의 표고 1,520m에 자생하고 있는 주목(Taxus cuspidata) 및 구상나무(Abies koreana)와 이식되어 관리하고 있는 동종에 대한 수분상태를 비교하였다. 오전 중(10시45분)에는 자생 수목에 비해 이식 수목의 잎의 온도가 높고, 상대습도는 낮았으며, 증산량은 적고 수분포텐셜은 높았다. 가장 정점에 도달한 시간(12시55분)에는 자생수목에 비해 이식 수목의 잎 온도가 낮고 상대습도는 높았으며 증산량이 적고, 수분포텐셜은 낮았다. 시간이 경과되면서 오후(14시15분)에는 자생 수목에 비해 이식 수목은 상대습도는 높고, 잎 온도가 주목은 낮았으나 구상나무는 높았으며, 수분포텐셜은 낮고 증산량이 주목은 적었으나 구상나무는 많았다. 따라서 이식된 구상나무가 수분스트레스를 더 받고 있었음을 알 수 있었다. 또한 기공확산저항의 급격한 증가와 함께 증산량이 현저히 감소된 시간대(오후 17시35분)에는 자생 수목에 비해 이식 수목이 잎의 온도가 높고 상태습도가 낮았으며 증산량은 많고 수분포텐셜은 낮아서 수분스트레스를 받고 있었다. 따라서 자생 수목에 비하여 이식 수목은 수분 증산량은 많으나, 수분포텐셜이 낮기 때문에 수분 대사의 불균형이 발생하게 되며 이것이 수분스트레스를 일으켜 수목이 고사하는 요인이 되는 것으로 판단되었다. 특히 열악한 아고산지대의 제한된 일부 지역에서만 분포하고 있는 구상나무에 있어서 이식한 경우 그 차이는 가장 뚜렷하였고, 그 결과 이식한 주목보다 구상나무가 고사율이 높다는 것을 입증할 수 있다. The water conditions of natural and transplanted trees of Taxus cuspidata and Abies koreana were experimentally compared at the altitude of 1,520m on Hyangjeokbong(1,614m), Mt. Deokyou, on June 15 to 18, 1997. The diurnal water conditions of transplanted trees compared with those of natural trees are as follows : Transplanted conifers were maintained high leaf temperature, low relative humidity, less transpiration and high water potential at 10:45 in the morning. The maximum peaks of transplanted conifers were sustained low leaf temperature, high relative humidity, less transpiration and low water potential at 12:55 in the afternoon. As time passed, water conditions of transplanted Taxus cuspidata were maintained low leaf temperature, high relative humidity, less transpiration and lower water potential at 14:15 in the afternoon. On the other hand, those of transplanted Abies koreana were maintained low high temperature, high relative humidity, more transpiration and low water potential at 14:15 in the afternoon. Also transplanted conifers were maintained high leaf temperature, low relative humidity, more transpiration and low water potential at 17:35 in the afternoon. As the results, more transpiration and low water potential of transplanted conifers facilitated the dryness of these trees. Accordingly, such water stress give rise to dieback of the transplanted trees. In addition, it was found that transplanted Abies koreana in subalpine zone were more sensitive rather than transplanted Taxus cuspidata in water conditions of soil.

The phytosociological investigation was carried out at 32 sites of the riparian vegetation in Musim-Chon stream passed through Choengju-City, Chungcheongbuk-Province by Braun-Blanquet's method from August to October, 1997. The flora of vascular plants in this survey was 202 species. The riparian vegetation was classified into 25 communities as follows. The submerged hydrophytes are Potomogeton malaianus var. latifolius community, Potomogeton crispus community, Myriophyllum verticillatum community-Hydrilla verticillata community and Ceratophyllum demersum community. The floating-leaved hydrophyte is Trapa japonica community. The emerged hydrophytes are Phragmites communis community, Perzicaria thunbergii community, Phragmites japonica community, Oenanthe javanica community, Zizania latifolia community and Persicaria hydropiper community. The herbaceous vegetation of floodplain are Artemisia montana community, Humulus japonicus community, Miscanthus sacchariflorus community, Erigeron anmus community, Impatiens balsamina community, Bidens frondosa community, Setaria viridis community, Ambrosia artemisiifolia var. elatior community and Eragrostis ferruginea community. The woody vegetation of floodplain are Robinia pseudo-acacia community, Stephanandra incisa community and Clematis apiifolia community. The species diversity was low in the upper and down stream, while the diversity was high in the mid stream situated at the center of Choengju-City because of frequent disturbance by citizens. These results suggested that distribution of communities and species diversity was closely related to the disturbance.
