Objective : This study was conducted to investigate into the etymology of 218 species names for 128 woody herbal medicines in Korea. Methods : The examined herbalogical books and research paper which published at home and abroad. Results ; This study was conducted to investigate into the etymology of 218 species names for 128 woody herbal medicines in Korea. The origins of species names for woody herbal medicines in Korea were in order of the local place name by thirty seven(16.97%), the dialects and old name by twenty two(10.09%), the morphological characters of leaves by twenty(9.17%), the plant's constituents and uses by fifty(6.88%), the person's name by fifty(6.88%), the other's generic names and species names by thirteen(5.96%), the morphological characters of flowers by twelve(5.50%), the morphological characters of stems by twelve(5.50%), the words meaning a number by twelve(5.50%), the relative characteristic by comparing with the same genus by twelve(5.50%), and so on.

The low virus titer in woody plant tissues and the presence of inhibitor compounds such as polyphenols, tannins and polysaccharides are common difficulties that compromise purification of plant viroids from their woody hosts. A simple, reliable method of RNA isolation using CF11 cellulose column on a microcentrifuge tube scale for detecting Apple scar skin viroid (ASSVd) in apple was developed. Total RNA extracted from leaf, woody bark and the fruit skin was used for reverse transcription. RT-PCR products could be detected from RNA prepared from dormant woody bark, fruit skin and fresh leaves with both the CF11 cellulose column method and NucliSens extractor in February, August and November. Meanwhile, with the RNeasy kit RT-PCR, products were detected only in leaves and not from bark or fruit skin. The PCR product, about 330 base pairs, was analyzed by agarose gel electrophoresis. The CF11 cellulose column method was effective for detecting ASSVd. The method enabled the processing of a large numbers of samples of dormant woody bark, leaf and fruit skin of apple.

Essential oil was extracted from cones of metasequoia (Metasequoia glyptostroboides) by steam distillation, fragrance was determined by sensorial analysis and chemical compositions were analyzed by gas chromatography-mass spectrometry with solid-phase microextraction apparatus. Metasequia contained 0.40% of essential oil in the cone. Major impact fragrances of the essential oil were woody, coniferous and herbal, and minor impact fragrances were minty, spicy and oily. There were nine constituents in the essential oil : 8 hydrocarbons and 1 oxide. Constituents were limonene (66.18%), ${\delta}$-3-carene (11.11%), ${\beta}$-caryophyllene (6.66%), ${\beta}$-myrcene (5.92%), ${\beta}$-pinene (4.14%), caryophyllene oxide (2.39%), camphene (2.32%), ${\alpha}$-caryophyllene (0.85%), and tricyclene (0.43%). Herbal and minty frangrances could be due to limonene and ${\delta}$-3-carene, spicy frangrance to caryophyllene, woody and coniferous frangrances to ${\alpha}$-pinene and ${\beta}$-pinene, and oily fragrance to camphene.

Result : The herbaceous plants in Ulleung island were 12 family and 22 species, Compositae and Liliaceae plants take the highest number of them. The woody plants in Ulleung island were 1 family(Araliaceae) and 2 species. The herbal medicines that originated from the wild edible greens of Ulleung island were 25 species. The herbal medicines that have the effects of clearing away heat(淸熱), eliminating toxin(解毒), subduing swelling(消腫) and promoting blood circulation to remove blood stasis(活血祛瘀) take the highest number of the effects of these herbal medicines. Conclusion : For the purpose of making use the wild edible plants of Ulleung island smoothly, we should recognize not only medical benefits but also matters that pay special attention.

This study was carried out to survey the vascular plants in 6 regions including around Hopo-Bridge of Yangsan region at waterfronts of Nakdong river, Korea. Distributed plants were surveyed from April to November, 2011. The vascular plants in 6 regions (around Mulgeum-chuisujang, Mulgeum-station, Jeungsan-ri, Hopo-bridge, Kumoh-bridge and lower part of Yangsan-stream) were total 135 taxa of 3 divisions, 4 classes, 37 orders, 66 families, 116 genera, 114 species, 2 subspecies and 19 varieties.

Background and objective: This study analyzed the growth characteristics, in relation to the soil moisture content, of trees planted in an environment with limited soil depth to provide the baseline data for effective irrigation management. Methods: The experimental treatment was divided into soil moisture contents (SMC) of 20%, 15%, 10%, 5%, and 1%, and the respective watering times were set accordingly. As for plant materials, Nandina domestica, Euonymus alatus, Thuja occidentalis, Hibiscus syriacus, Pinus densiflora, and Pyracantha angustifolia, were chosen for this study, because they are highly likely to be used in urban street environments. Results: The minimum irrigation point suitable for each species was determined by considering various aspects of visual quality and water efficiency in terms of plant growth, including characteristics such as height, root diameter, rootlet development, and weight. Our results indicate that N. domestica should be watered so that the moisture content of the soil is of at least 5%, based on the balance between the stem and roots, as well as on visual quality. E. alatus and P. angustifolia are suitable for watering that results in at least 10% SMC, considering the height, root growth, weight, and visual quality of plants. As for T. occidentalis, it showcases moderate growth with a soil moisture content of at least 5%. Finally, the minimum irrigation time required to obtain 15% SMC is appropriate, in terms of plant growth, fresh weight, and visual quality, for H. syriacus and P. densiflora. Conclusion: This study suggested a basic irrigation guideline for container gardens where trees planted in environments with limited soil depth can be managed so that they are visually appropriate and in good condition of growth.

Forest tree species usually takes for long periods to be harvested and cultivated but spearmints are a good model system for woody plant because of reducing and shortening cultivation time. Spearmints are good model plants (Mentha species) for research about terpenoids production and industrial essential oil manufacture. Isopentenyl pyrophosphate isomerase (Iso) and limonene synthase (Limo) are the key enzymes of terpenoid biosynthesis pathway. Transgenic and wild spearmints (Mentha spicata, MS) were cultured in vitro and assessed for the essential oil contents. The content of essential oil of transgenic spearmint also was enhanced slightly depending on the target terpenoid genes. In an attempt to increase productivity of terpenoids further, salt and fungal elicitation strategy was adopted on transgenic Mentha spicata. The salt (800 mM NaCl) as abiotic and two fungi (Botrytis cinerea and Glomerella cingulata) as biotic were used for elicitors. In the absence of salt stress four terpenoids were detected from the spearmint extracts, all of them being monoterpenes. On the other hand, the transgenic (MSIso) extracts contained eleven terpenoids (10 monoterpenes and 1 phenylpropene) while transgenic (MSLimo) extracts contained seven monoterpenes. After 3 days of fungal infection, the resistance indices further increased to 4.38, 3.89 and 2.04 for wild type, MSIso and MSLimo, respectively. The salt and fungal elicitators proved beneficial towards modifying both the terpenoids profile and improvement in the composition of essential oil. These results have important applications for the large-scale production of essential oils and forest biotechnology with respect to spearmint.
