DOI : 10.7732/kjpr.2014.27.2.111
Contents of phenolics, flavonoids, and catechins, and antioxidant activity were investigated in the ethanol extracts of three different flower species, Magnolia denudata, Prunus mume, Carthamus tinctorius. Total phenolics were more present in M. denudata than P. mume or C. tinctorius, ranging from 72.6 to 118.0 mg/kg (p < 0.05). Total flavonoids level had same tendency to total phenolics content, showing highest amount (25.1 mg/kg) in M. denudata. The antioxidant activity of the methanol extracts from all the flowers dose-dependently increased. DPPH free radical scavenging activity at 250 mg/kgwas higher in M. denudata and P. mume by 93.0 and 92.6%, respectively, than C. tinctorius by 23.0% (p < 0.05). Total catechins content including 6 compounds was higher in M. denudate (9,425.5 mg/kg) than that in P. mume or C. tinctorius (3,407.8 or 190.6 mg/kg). However, P. mume extracts showed highest amount in caffeine as well as vitamine C. DPPH radical scavenging activity in three different flowers was highly correlated with contents of total phenolics (
), total flavonoids (
), and total catechins (
), and their content and activities were different depending on species.

This study was accomplished to investigate the effect of harvest time on the contents of polyphenolic compounds such as epicatechin, catechin, resveratrol and quercetin in grapes (Vitis spp.). The souble solids contents were increased with harvest time delay, while the titratable acidity continuously decreased in all cultivars. Brightness (L) was higher in 'Campbell Early' and 'Shigyoku', Hunter a value was high in 'Shigyoku' which was harvested later. Hunter b value seemed to be different in 'Shigyoku' depending on harvesting time. The contents of EC which was extracted 'Campbell Early, 'Shigyoku' and 'M.B.A' were higher late harvest time than early harvest time, reapectively, In 'Shigyoku which requires the direct light, the contents of EGC and EC showed distinct differences depending on harvesting time. The compositions of epicatechin were different depending on cultivars. The contents of catechin and resveratrol were higher in 'Campbell Early' and 'M.B.A' which were harvested later, but 'Shigyoku' which was harvested earlier. The contents of quercetin was higher in 'Campbell Early' which was harvested earlier, but 'Shigyoku' and 'M.B.A' which were harvested later. In comparison with 'Shigyoku' and 'M.B.A', catechin and resveratrol contents were seen to be higher in 'Campbell Early' irrespective of harvesting time.

DOI : 10.7732/kjpr.2014.27.2.125
In this study, the chemical constituents of bulb from Lilium lancifolium and Lilium tsingtauense were investigated. The content of moisture, crude protein and fiber of bulb from L. tsingtauense was higher than that of L. lancifolium, whereas the content of crude ash and nitrogen free extract of bulb from L. lancifolium was higher than that of L. tsingtauense. HPLC analysis revealed that total free sugar and amino acid content of bulb from L. tsingtauense was higher than that of L. lancifolium. There was no remarkable difference in proximate composition between the two species. The content of p-coumaric acid and ferulic acid was 1.93 mg% and 0.25 mg% in ethyl acetate fraction of L. lancifolium, on the other hand, 2.94 mg% and 0.46 mg% in ether fraction of L. tsingtauense. These results suggest that the bulb of L. tsingtauense can be considered as promising oriental medicine resource likewise L. lancifolium.

We investigated the flora of Yeoseo-do (N
), located in Wando-gun, Jeollanam-do, South Korea and discussed the vascular plants found there. Four separate field trips were completed from April to October of 2013. The vascular plants were summarized as 463 taxa; 112 families, 306 genera, 409 species, 6 subspecies, 42 varieties, 5 forms and 1 hybrids. The number of endemic species of Korea were 6 taxa, and 12 taxa designated by the Ministry of Environment as red data of endangered vascular plants were investigated in this region. There were a total of 98 taxa of floristic regional indicator plants and one taxon of level I endangered species, Neofinetia falcata (Thunb.) Hu, as designated by the Ministry of Environment. 33 taxa have shown their southern distributional limit ranges, and 10 taxa of halophytes were confirmed in the Yeoseo-do (Isl.). In additon, 27 taxa of the naturalized plants were recorded.

The habitats characteristics of Exochorda serratifolia were investigated to compile basic data for conservation and restoration. Natural habitats were located at an altitude of 1 m to 624 m above sea level with angles of inclination ranging from 2 degrees to 81 degrees. A total of 248 vascular plant taxa were identified from 37 quadrats in 16 habitats. The importance value of Exochorda serratifolia is 18.70%, and 5 highly ranked species such as Rhododendron mucronulatum (3.79%), Abelia tyaihyoni (3.27%), Euonymus alatus for. ciliatodentatus, Quercus mongolica (3.23%), and Indigofera kirilowii (2.97%) are considered to be an affinity with Exochorda serratifolia in their habitats. Species diversity was 1.03, dominance and evenness were found to be 0.15 and 0.85, respectively. Average field capacity was 24.19%, the organic matter was 8.21%, pH was 5.52, and available phosphorus was
. Correlation coefficients analysis based on environmental factors, vegetation, and soil analysis shows that the coverage of Exochorda serratifolia is correlated with field capacity and available phosphorus.

This study was carried out to investigated the effects of soil type and light condition on seedling quality of rare and endemic plants Orostachys iwarenge and Orostachys iwarenge for. magnus. The best seedling quality of O. iwarenge and O. iwarenge for. magnus seedling were shown in Klasmann soil at non-shading or LED (Red+Blue) condition, 50% shading or LED (Red+Blue) condition, respectively. Survival of O. iwarenge seedling was not influenced by the period of experiment but survival of O. iwarenge for. magnus seedling in sandy soil conditions decreased significantly. Results of correlation analysis of seedling quality and survival rate, indicated that O. iwarenge showed a correlation of 0.8 or more at plant height, leaf length and fresh weight. O. iwarenge for. magnus showed a correlation of 0.8 or more at plant height, leaf width and leaf length. Especially, seedling survival of O. iwarenge and O. iwarenge for. magnus showed a correlation of 0.8 or more at first seedling survival and second seedling survival. It was important to manage the early seedling stages of O. iwarenge and O. iwarenge for. magnus. Therefore, seedlings with plant height (over 2.5~4 cm) and root length (over 3~5 cm) were grown vigorously at 35 days after the seedling was transplanted in mid-April in Klasmann soil of 72 plug cell tray at LED (Red+Blue) conditions.

Hovenia dulcis var. koreana Nakai, the oriental raisin tree, has been considered not only fruit but an herbal medicine in East Asia including Korea, Japan and east China. As honey plant, value of this species had been rising steadily. The aim of this study was conducted to develop the propagation technique by scion collection time, scion age and vinyl house on survival rate of H. dulcis. The survival rate by veneer grafting showed no significant differences among 3 new cultivars. The scion collection at the northern temperature zone was observed to be the most appropriate time before the spring equinox when the plants are fully dormant. Especially, the installation of vinyl house showed 86% survival rate by veneer grafting. The scion age was effective 1 year shoot than 2 years shoot for increase the grafting survival rate. In this case, the installation of vinyl house can contribute above 80%.

DOI : 10.7732/kjpr.2014.27.2.188
The sap outflow characteristics of Juglans sinensis and J. mandshurica were investigated to evaluate the optimum pruning period of walnut tree that there is a sap spill on dormant. The total period of sap outflow were 34 days for both J. sinensis and J. mandshurica. Total amount of sap outflow per tree in J. sinensis and J. mandshurica were 2,922 mL/tree and 3,135 mL/tree, respectively and the period of sap outflow and non sap outflow between two species were similar. ANOVA analysis showed that the amount of sap outflow was significant differences with day of sap outflow but there were no significant differences between species. From the correlation analysis between air-temperature and sap outflow, daily minimum temperature showed a positive correlation at the 1% level of significance (r=0.56 and r=0.46) for both J. sinensis and J. mandshurica. When branch of walnut tree that diameter is 5 cm cut on the period of sap outflow, the sap flowed down the longest period (48 days) but the sap outflow was not observed after budburst. Therefore, our study supported that the pruning have to avoid the period of sap outflow to reduce sap outflow of walnut tree.

This study was carried out to investigate the characteristics and infection effects of AMF with soil samples collected at some sites in Gyeonggi province, Korea. AMF spore and characteristics of infection structure in upland plant root were observed as wet sieving and staining method, growth of Capsicicum annum was compared between treatment and non treatment. AMF spores isolated from each soil sample were ellipse or circle type and the colors were soft yellow and white. The colonization rate of AMF with soil infection of Zea mays roots was 13.3~83.3%, the rate of infected soil collected from Z. mays was higher on average. When compared to the growth of C. Annum with control after infection on C. annum, it wasn't showing many differences in fresh weight, dry weight and height, but the yield of fruit of C. annuum showed double than the control group.
