This study was conducted to determine chemical compounds and antioxidant in Aruncus dioicus. Further, effects of cultural practices such as the shading conditions on the general compounds, essential oils and antioxidants. The chemical compounds and antioxidant activity of edible extracts on the shading cultivation and harvesting time were measured by crude fiber, pigments, higher fatty acids, essential oils and DPPH free radical scavenging ability and activities of SOD and POD in edible shooting parts of Aruncus dioicus. The contents of crude fiber, total chlorophyll and total carotenoids in extracts of edible shooting by shading cultivation and later harvesting were higher than those of non-shading cultivation and early harvesting. Phenolic compounds such as benzoic acid were identified as the aromatic compounds in the edible extracts of Aruncus dioicus. The contents of azulene, benzaldehyde and linalool among those compounds on the cultivation conditions increased in shading cultivation.
values of DPPH free radical scavenging activities were high from 6.644 to
in extracts of edible parts and those of edible shooting parts was high such as edible shooting cultivated by 60% shading, 30% shading and non-shading, respectively. The activity of POD and SOD in seeds was lower than that of edible shooting and that by shading cultivation was high in extracts cultivated by non-shading. POD activity of extracts on harvesting time was high in earlier harvesting but SOD activity was low. The numbers of isozyme pattern of POD and SOD in seedling showed 7 bands and 3 bands, respectively, especially, bands of POD and SOD in the first year-growing plant did not show and show a difference according to plant positions, respectively.

The flora of vascular plants and the present vegetation status of Minjujisan and its adjacent regions were investigated from 2000 to 2004, total 27 times. The plant taxa of these areas consist of 764 taxa totally; 172 families, 397 genera, 631 species, 3 subspecies, 105 varieties and 25 forms. There were many useful plants such as 35 taxa of Korean endemics, 12 taxa of rare and endangered plants, and 101 taxa of specially designated plants which were determined by the Ministry of Environment. Furthermore, 46 taxa of naturalized alien plants were also investigated in the boundary of developing areas. The vegetation status of investigated area was comparatively well conserved, but the degree of damage was increasing rapidly by development, deforestation, and tramp which were induced by the disturbances of human beings. Therefore, more active conservation strategies such as expanded designation of conservation area. should be established, and carried out continuously based on the results of long-term monitoring studies.

The flora of vascular plants in Geojedo revealed to be 550 taxa based on only the voucher specimens to be collected. It comprise 108 families, 341 genera, 478 species, 69 varieties and 3 forms respectively. Among them, 13 taxa of Korean endemics and 8 taxa of rare and endangered plants were investigated in addition to 75 taxa of specially designated plants announced by the Ministry of Environment. Furthermore, 36 taxa of induced and naturalized plants were also observed in this area. One of the characteristics of forest vegetation is the broadly occupation of Pinus thunbergii on whole area of Geojedo. Although it's well condition and conservation status, the destruction area of vegetation was rapidly increasing by the industrial development, the deforestation and the tramp as well as by the basic disturbances of human beings. Therefore, more active and positive conservation strategy such as expansion of conservation area should be prepared rapidly by the results of long-term monitoring studies.

Nerine was originated from South Africa and around 30 kinds of species are distributed in worldwide. In present study we have characterized the condition of storage and growing conditions on the bulb propagation of Nerine by the tissue culture. Result indicated that the percentage of decrement, decay and sprouting of bulblets in the tissue culture was high at the higher temperature compare to lower temperature. The optimum conditions for storage and time were 12 weeks at
which were having 86.4% sprouting rate. The sprouting rate at different temperature and acclimation time, using bulblets in the tissue culture, were optimum at early June when temperature is relatively higher(
) that facilitate to breaking the dormancy. Growth characteristics and capacity of photosynthesis of Nerine were better at red and blue mixed lightness.

The genetic analyses of Acanthopanax senticosus Harms from Korea, China and Russia, were made by comparing the internal transcribed spacer (ITS) sequences of the nuclear ribosomal DNA. The ITS region of A. senticosus was amplified by polymerase chain reaction (PCR) using the universal primers and then directly sequenced. The length of the ITS region including 162 bp 5.85 rRNA gene ranged from 608 bp (for Korean and Chinese) to 611 bp (for Russian). The G+C content of ITS region were 60.20% for Korean and Chinese plants and 60.06% for Russian plants. Sequence comparisons indicated that ITS regions of A. senticosus from Korea and China were identical, whereas the ITS sequence of A. senticosus from Russia showed 99.2% homology with the plants from Korea. Variation in sequences were attributable to 5 bp substitution such as transversion or insertion events. These results suggested that A. senticosus Harms from Korea and China were closely related in phylogenetic relationship compared to Russian. In addition, A. senticosus Harms were more similar to Kalopanax pictus than A. sessiliflorus in their ITS sequences.

This study was conducted to investigate the changes in some physicochemical properties, including pH, moisture and ash content, Ca, Na, Mg, K, crude saponin and codonoposide, of cultivated Codonopsis lanceolata, which were packed with woven polypropylene(WP) or low density polyethylene(LDPE, thickness 0.04 mm) bag and stored at
for 30 days. pH of the juice of fresh Codonopsis lanceolata was 5.3 and decreased significantly during storage. Storage temperature exerted more influence upon the content of moisture and ash than package materials. The concentration of Ca, Mg, Na and K were 427.3mg, 203.4mg, 10.2mg, and 619mg per 100g dry matter respectively. The contents of Ca and Na were not changed significantly, but the contents of Mg and K were decreased during room temperature storage. It was revealed that the juices of stored sample had darkened and redness and yellowness were somewhat deeper than those of fresh sample. 1g of the cultivated Codonopsis lanceolata had 29.3mg of crude saponin and 3.78mg of codonoposide, and the changes of them during storage at various conditions were not significant.

Korean Journal of Plant Resources, volume 19, issue 1, 2006, Pages 68~75
This study was conducted to investigate the combination of proper culture medium for differentiation culture of Chrysanthemum zawadskii var. latilobum KITAMURA. The combinations of culture medium were consisted with an inorganic materials such as vermiculite, perlite, saprolite, sand and upland top soil, and with an organic materials such as peat-moss, leaf mold and compost. For the plant growth characteristics, the plant height, number of tiller, root length and root weight in the combination of leaf mold was relatively great as compared to the treatment with peat-moss and compost. It was considered that humus might be contributed to improve the physical properties of soil as well as the sequential nutrient supply. For the combination of peat-moss, the plant growth was not good because of not sufficient nutrient supply, Also, the plant growth in the treatment of compost was so bad because of enhancement of culture medium pH 8.9 and increasement of phosphorous content.

Genetic variation of two Juniperus chinensis var. sargentii populations in Mt. Seorak and Mt. Halla was investigated by isozyme analysis at reproducible 11 loci of 7 isozyme systems(Aat-1, Aat-2, Gdh, Idh, Lap, Mdh-1, Mdh-2, Mdh-3, 6Pgd, Pgi-1, and Pgi-2), of which 7 loci were polymorphic. The levels of genetic diversity of two populations were A=2.2,
(Mt. Seorak population) and A=2.1,
(Mt. Halla population), respectively. These values were similar to and/or somewhat higher than those observed in other Korean native conifers. Moderately low degree of genetic differentiation was observed between 2 analyzed populations (
). Heterozygosity of the population in Mt. Seorak was significantly lower than expected, and much high level of inbreeding coefficient(F=0.376) was observed. Considering the limited population size and distribution range of the population, the population seemed to be influenced by inbreeding and/or random genetic drift, Consequently, Mt. Seorak population should be considered to be a more important candidate for the conservation of J. chinensis var. sargentii.

This study was conducted to investigate effect of temperature and NaCl on the seed germination and water absorption of Thuja orientalis. Seeds were treated with 0, 500, 1,000, 2,000 and 4,000ppm of NaCl and placed in different chambers at 15, 20, 25 and
, respectively. And seed properties and relative water absorptions were analyzed. Germination decreased with the increase of both temperature and NaCl concentration, and especially the difference was obvious at
. Dormancy and mortality increased with the increase of temperature in non-NaCl treatment. Two-way analysis of variance showed significant effects of temperature, NaCl concentration and interaction between temperature and NaCl concentration (p<0.001). Mean germination time increased with the increase of NaCl concentration at 15, 20 and
but decreased at
because the seeds were mortal by NaCl high concentration, Germination speed and germination performance index decreased with the increase of NaCl concentration. Those represented decreasing tendency with NaCl concentration but high positive correlation with germination. Relative water absorption decreased with the increase of NaCl concentration and represented high values at
, and showed high positive correlations with germination, germination speed and germination performance index. It was reported that the high temperature and salinity were inhibitive factors of seed germination of Thuja orientalis.

The objectives of this study, an analysis of fruit and leaf morphological characteristics among the five Zizyphus cultivars could be used for the investigation of cultivars classification and could provide information to make out the UPOV TG(Test Guidelines). ANOVA tests showed that there were statistically significant differences in all fruit and leaf morphological characteristics among the five Zizyphus cultivars at 1% level. But, for kernel characteristics, differences were statistically non-significant among the cultivars. Approximately, the Wolchul and Boeun cultivars showed larger and smaller values in overall characteristics and cultivars, respectively. The results of principal component analysis(PCA) for the fruit and leaf morphological characteristics showed that the first for principal components(PC's) explained about 65.3% of the total variation. The first PC was correlated with those characteristics that were mainly related to the terminal leaf length(TLL), leaf length(LL), fruit length(FL), terminal leaf width(TLW), and leaf petiole length(LPL). The second and third PC was mainly correlated with the terminal leaf morphological index(TLMI). Therefore, these characteristics were important to analysis of the fruit and leaf morphological characteristics and classification among the five Zizyphus cultivars. Cluster analysis using UPGMA method based on principal components showed that five Zizyphus cultivars could be clustered into two groups. Group I comprises Mudung, Wolchul, and Bokjo and Geumsung cultivars, Group II is Boeun cultivar. These results well similar to that of principal component analysis.

This experiment was conducted to investigate growth and flowering characteristics of Celosia argentea native to Korea treated by monthly sowing from January 20 to August 20 in the field. As sowing date delayed from January to June, the days to flowering were increased. Seedlings sown on February and March planted in the field on April and May were shorter, 31 days to flower, shorter plant height, much more number of flower than those of sown on May and June planted in the field on July and August which means Celosia argentea may be facultative short day plant. And the seedlings sown on February and March were precious ornamentals for bed plant from summer to fall, however, the seedlings sown on April and May were valued for bed or cut plant producing in fall.

Korean Journal of Plant Resources, volume 19, issue 1, 2006, Pages 169~173
The effects of aqueous extract and volatile substances of 2 Angelica plants on seed germination and seedling growth were investigated. The seed germination of Angelica gigas showed increase in proportion to increase in aqueous extract concentration of A. gigas, while that of Angelica acutiloba was reduced proportionally to the extract concentration. The seed germination of A. gigas and A. acutiloba treated with aqueous extract of A. acutiloba was inhibited. The seedling elongation of A. gigas and A. acutiloba was slightly increased at lower concentration of aqueous extract of A. gigas, whereas it was proportionally decreased at higher concentrations. The seedling elongation of 2 Angelica plants was decreased by the aqueous extract of A. acutiloba. The aqueous extract of A. acutiloba caused significant inhibition in seedling growth of 2 Angelica plants. The seed germination of Lactuca sativa was not affected by volatile substances emitted from 2 Angelica plants. The radicle elongation of L. sativa treated with volatile substances of 2 Angelica plants was inhibited slightly and it was not suppressed according to the concentration of volatile substances.

This study was carried out to offer the raw data on the method of cultivation and ecological characteristic by systematical analysing habitat environment of Tulipa edulis that was expected as medicinal and ornamental resource. The habitat environment was that the altitude was 245 m, the aspect of south, the size of approximately
, and there was analyzed that Tulipa edulis grew wild in the dryly sunny spot. The vascular plants were summarized as 62 taxa; 28 families, 59 genera, 50 species, 11 varieties and 1 forms, and the resource plants were classified that there were 23 taxa of ornamental plants(37.1%), 43 taxa of edible plants(69.4%), 34 taxa of medicinal plants(54.8%) and 29 taxa of others(46.8%). In the results of soil factors analysis, there showed that acidity was pH 4.9, organic matter content of 4.9%, available
of 3.6 mg/kg, exchangeable
, cation exchange capacity(C.E.C) of
and electrical conductivity(EC) of 0.3 dS/m. In the results of correlation analysis between soil factors, exchangeable
and C.E.C were highly correlative. The growth characteristics of Tulipa edulis were surveyed that height was 7.6 cm, leaf width of 0.6 cm, leaf length of 12.7 cm, flower width of 2.8 cm, peduncle of 5.4 cm and chlorophyll of
. In the results of correlation analysis between growth characteristics, height and peduncle were highly correlative. In the results of correlation analysis between soil factors and growth characteristics, exchangeable
and leaf length were high relativity but they were confirmed negative relation. In the results of growth model analysis, R-square of leaf width and exchangeable
was some 86.4% and that of chlorophyll and exchangeable
was some 83.7%.

We investigated the genetic variation in Stewartia koreana Nakai by examining 61 I-SSR amplicons in 120 individuals distributed among six natural populations in Korea. The overall percentage of polymorphic I-SSR amplicons was 81.9% and mean number of amplicons per I-SSR primer was 12.2. Levels of genetic diversity within 6 populations were similar each other[Shannon's Index
(mean: 0.407)]. The Mt. Obong population had the highest level of genetic diversity and was most distinctive from the other populations. Most variation existed among individuals within population(88.2%). Genetic differentiation among populations(
) was 0.118. The UPGMA dendrogram based on the genetic distance failed in showing decisive geographic relationships.
