    Mt. Hwang-ak, as a temple forest belongs to Baekdudaegan. flora investigation was conducted to better know of current natural environment. At the same time, For the understanding of planted plants which is in the traditional Korea buddhism temple for landscape, research on Jikji temple had taken place during 2019 April to October with 12 times. As a result, the list of plants at Mt. Hwang-ak was classified as a total of 534 taxa comprising of 96 families, 312 genus, 462 species, 4 subspecies, 59 varieties, 9 forma. This listed plants could be classified as 4 categories by each standard. the listed plants were 14 species of Korean endemic plants, 13 species of Rare plants data book in korea, 34 species of Invasive Alien Plants in South Korea with 10% of Urbanization Ratio and 6% of Naturalization Ratio respectively, 167 species of List of Medicinal Resources Plants in Korea. In the Temple of Jikji, could find 81 species of planted plants that widely distributed all around the temple for landscape. Compared to other temple, We could observed 51% of species were overlapping, Among them, 9% of species overlapping with more than three temples. - COLLAPSE

    This study was conducted to analyze community structure and species composition of Abies koreana forest. Field survey was carried out from June, 2019 to 2020, September. 121 plots (20×20 m) were set up, 5 herb layer plots (3×3 m) were constructed for each plot, and there, Diameter at Breast Height(DBH), height, environmental factor were measured. It was analyzed that water stress did not have a significant effect on the factors affecting the growth of A. koreana in Mt. Halla-san, and in the case of Mt. Deokyu-san, the more forest stands located at the ridge, the higher the tree density. It was found that the factors affecting the distribution of Abies koreana were not consistent according to the environment of study site. - COLLAPSE

    The in vitro regeneration was established, and the genetic stability among the mother plants (control) and the micropropagated green plants was evaluated using ISSR markers in Imperata cylindrica ‘Rubra’, Poaceae which containing important bioenergy plants. Green shoots were multiply induced from growing point culture via callus on MS medium supplemented with 0.01 mg/L NAA and 2 mg/L BA, and the shoots were proliferated on the MS medium with rooting. Rooted plantlets were transplanted to the pot with 100% survival rate. Using ISSR markers, somaclonal variation was analyzed in eight mother plants (control), ten green-regenerant cultivated at culture room (ReR) and ten green-regenerant cultivated at field condition (ReF). All ISSRs produced a total of 97 bands, and the scorable bands varied from one to seven with an average of 4.4 bands per primer. The polymorphism rate of ReRs and ReFs was 4.1% and 3.1% respectively, showing higher rate than that of control (0%). The genetic similarity matrix (GSM) among all accessions ranged from 0.919 to 1.0 with a mean of 0.972. According to the clustering analysis, ReFs and mother plants were divided into two independent groups. The results indicate that no clear genetic diversity was detected among regenerated plants, and ISSR markers were useful tool for identification of somaclonal variation of regenerants. - COLLAPSE

    This research was conducted to investigate the effect of foliar application of 6-benzylaminopurine (BA), sprayed weeks after pinching (SWP), on ornamental usage of Veronica longifolia L, which is native to Korea. Foliar application of 0, 500, 1,000, and 2,000 ㎎/L BA on 10 ㎝ long V. longifolia L. plant was evaluated at 0, 7, and 14 days after pinching for growth and flowering. The maximum result of multiple shooting was seen in the 2,000 ㎎/L BA at 1 week after pinching, and almost all the treatments showed dwarf growth in V. longifolia L. The number of days to flowering was delayed by BA treatments. Moreover, the length and the number of flowers decreased with high concentrations of BA. Thus, foliar application of BA via pinching technique can improve the ornamental usage of V. longifolia L. by controlling the plant type. - COLLAPSE

    The Hosta ‘Hwangnarae’ was bred at the Korea National Arboretum, which was induced using ethyl-methane-sulfonate (EMS) to obtain mutants. Among the leaf variegated Hosta plants, some with yellowish-green color pattern on the edge of the leaves was selected. They were cultivated through vegetative production. Assessment of the botanical characteristics was executed for six years from 2013 to 2018. Major characteristics such as yellowish-green color pattern on the edge of leaves appeared uniformly and was finally selected in 2019. The Hosta ‘Hwangnarae’ that have been bred in this way can prove to be useful as material for a ground cover plant or pot plant. - COLLAPSE

    The purpose of this study was to compare the chemical properties of the bokbunja distributed in Korea with the content of the bioactive substance ellagic acid. The bokbunja was Rubus coreanus group and Rubus occidentalis group were compared, domestic bokbunja and import bokbunja were compared. In bokbunja, free sugar was 30.89 ± 0.7 ㎎/g of Rubus coreanus and 29.05 ± 0.87 ㎎/g of Rubus occidentalis. and 27.28 ± 7.4 ㎎/g of domestic bokbunja and 21.58 ± 6.73 ㎎/g of import bokbunja. The free amino acids was 4.50 ± 0.08 ㎎/g of Rubus coreanus and 5.05 ± 0.08 ㎎/g of Rubus occidentalis. and 4.13 ± 1.09 ㎎/g of domestic bokbunja and 3.75 ± 0.31 ㎎/g of import bokbunja. Validation of the ellagic acid method was confirmed by comparing the retention time and spectrum of the standard and extract using HPLC. The calibration curve (R2) showed linearity of 0.9999. As a result of analyzing the ellagic acid content of each extraction solvent, DMSO and methanol mixture extracts were high, and Rubus coreanus was 2.56 ㎎/g and Rubus occidentalis was 3.16 ㎎/g, which was not significantly different (p < 0.05) In addition, the ellagic acid content of domestic bokbunja and import bokbunja was 2.83 ㎎/g and 2.99 ㎎/g, which was not significantly different (p < 0.05). - COLLAPSE

    In this study, we investigated inhibitory effect of red sweet pepper (Capsicum annuum L.) on triglyceride biosynthesis in Rhodosporidium toruloides. There was no significant difference in the total lipid content of all the experimental groups including 0.02, 0.1 and 0.5% (w/v) of red sweet pepper 70% ethanol extract treatment (RSPE). However, the triglyceride content was significantly decreased in RSPE group campared to the control group. When the formation of lipid droplet in the oleaginous yeast was examined, a small amount of fluorescence was observed compared to the control as the concentration of RSPE increased. The number of cells and free fatty acid increased in a concentration-dependent manner. These results suggest that RSPE has an anti-obesity effect. - COLLAPSE
