Korean Journal of Plant Resources, volume 21, issue 1, 2008, Pages 1~4
The clonal variation in female flowering was studied in Larix leptolepis clone bank, consisting of 116 clones, for three years. The between-year variation was large; i.e. the percentage of flowering grafts and average number of flowering per graft were
, respectively. Differences in flowering abundance among clones were large and statistically significant in all the years studied. The variance of flowering abundance among clones was increased when flowering was poor. The average of broad-sense heritability of flowering abundance was 0.52. The genetic gain(%G) was estimated at 57.4% when the upper 30% clones were selected. The clonal stability of flowering abundance was compared using average number of flowering and coefficient of variance value of each clone. The clones such as Gyeonggi 9(29), Kangwon 37(137), Chungnam 6(46), Chungnam 14(414), R11, R8 showed abundant flowering and high stability.

Korean Journal of Plant Resources, volume 21, issue 1, 2008, Pages 5~11
This study examined the characteristics of Pinus thunbergii community that forms a windbreak forest around the coast of Gwanmaedo located in Jodo-myeon, Jindo-gun, Jeollanamdo which is located in the south-western areas of Korea from December 2005 to April 2007 and to suggeste the ecological management methods of coastal windbreak areas. P. thunbergii community, a coastal windbreak forest of Gwanmaedo, was classified into disturbance, growth, mixture, stability, and back mountain vegetation according to major companions species and vegetation types. P. thunbergii community of disturbance and growth vegetation needs active management through tree thinning, mowing, weeding out, use of rest space, and felling sick pine trees. P. thunbergii community of mixture, stability, and back mountain vegetation needs active preservation of a coastal windbreak to restore natural vegetation by making a windbreak walk and a forest buffer zone and inducing vegetation succession. Accordingly, in this study, ecological management methods were suggested according to the actual state of distribution by habitat characteristics of coastal windbreak areas such as management of beaches and surrounding area of idle lands, restoration of back wetlands, inhibition of foreign plants, maintenance of diversity of species and habitats, and prevention of aging and spread of damage from insects.

Antioxidative activity and inhibitory activity of angiotensin I converting enzyme(ACE), aminopeptidase N(APN) and
-amylase were investigated in the methanol extracts from 25 fern plants native to Jeju Island, in order to screen the plant species containing bioactive materials for functional foods or medicines. The antioxidative activity was higher in Cytomium fortunei(41.9%) and Rumohra standishii(34.1%) than in leaves of Thea sinensis(30.9%), a small tree for antioxidative beverage. Inhibitory activities of ACE and APN were relatively high in Cytomium fortunei as 26.7% and 28.2% respectively.
-Amylase inhibitory activity was higher than 50% in 10 species. Particularly, Cytomium fortunei(87.4%) and Dryopteris erythrosora(71.6%) showed the inhibitory activities higher than those of other form plants. Of 25 fern plants investigated here, Cytomium fortunei showed not only the highest antioxidative activity but also the highest inhibitory activity of ACE, APN and
-amylase. It suggests that Cytomium fortunei could be potentially used as a resource of bioactive materials for fuctional foods or medicines.

Traditionally mungbean(Vigna radiata L.) sprouts has been eaten soon after washing. The study was carried out to measure the effect of washing before packaging on morphological characters and color of mungbean sprouts. The seeds of cv. Zhong Lu 1 were soaked in 50 ppm BA solution immediately before 4 hour aeration and then cultured for 6 days. The sprouts were washed immediately before packaged with PE envelops or not, and then stored 5 days at
. Their morphological characters, fresh and dry weights, and colors were measured everyday. Compared to washed, nonwashed sprouts had more lateral roots although the two sprouts did nearly same in hypocotyl and root lengths, hypocotyl diameter, fresh and dry weights. Non-washed sprouts, moreover, showed higher brightness in hypocotyl and root and cutting resistance in hypocotyl although there were not significant differences in color a and b, meaning that the latter ones were more rapidly changed during their storage. In non-washed sprouts, number of lateral roots, hypocotyl length and diameter, total fresh and dry weights were nearly same up to 3 days and afterward were declined. Brightness and color b of hypocotyl were decreased with increased storage period although cutting resistance of hypocotyl was since 3 days after storage.

Several extracts of different parts and solvent fractions of Cornus kousa were obtained and their functional material contents, antioxidant activities and tyrosinase inhibition effects were determined. Content of total polyphenols and flavonoids contents in flower were 169.638
, respectively, which were much higher than those of other parts. Also, flower extracts showed the strongest effects on DPPH and ABTS radicals scavenging and ferrous ion chelating. In flower, leaf, and stem extracts, inhibition effects on peroxidation of linoleic acid determined by ferric thiocyanate(FTC) method were higher than a synthetic antioxidant, BHT. Tyrosinase inhibition activities were shown only in flower extract. Flower and leaf extracts, showing high biological activities in various system, were successively reextracted with n-hexane, chloroform, ethylacetate and n-butanol. Total polyphenol contents of water fractions were higher than any other solvent fractions in both flower and leaf, 67.006
, respectively. But total flavonoid contents were higher in ethyl acetate fraction for flower extract and butanol fraction for leaf extract. Among the solvent fractions, the highest efficiency of free radical scavenging activities was obtained in ethyl acetate fraction for flower extract and n-butanol fraction for leaf extract. Tyrosinase inhibition activities were higher in water fraction for both flower and leaf extracts, 49.24% and 31.8%, respectively.

To product grafts and construct its spread-system effectively, this study was carried out to investigate into effects on the survival percentage and growth in walnut trees(Juglans sinensis Dode) according to transplanting type and post-epicotyl grafting treatment. In the average survival percentage of the grafting according to post-epicotyl grafting transplanting type, TPGB1(transplanting in grafting bed) showing 89.02% was highest. Also, the survival percentage was different from appropriate temperature and humidity within treatment. As a result of the average survival percentage of the grafting by species, KWN-3 having 81.59% was highest with high survival percentage of total treatment in general. In addition, it is concluded that the nutrition condition of scions and collecting parts are strongly related to survival percentage on having significantly difference of its survival percentage by species. The growth rate of the survival grafts by transplanting type after grafting revealed that all of the investigation items(height and diameter growth of grafts, diameter growth of scions and etc.) resulted in same trend. TPGB1 having the highest tree height growth, 15.97cm(
), showed the highest growth on diameter growth of shoots, 7.55mm(
), and scions, 8.12mm(
), as well. In the growth of each treatment according to different developing parts of shoots in grafts, the lateral bud, 12.05cm, was much superior to the terminal bud,9.57cm, on only graft height growth. However, the survival rate according to collecting parts of scions and developing parts of shoots with same treatment was not different with among-species.

This study was carried out to get the basic data for safflower cultivation according to sowing date by growth analysis for 2 years form 2003 to 2004 at Institute of natural product in Uiseong, G.B.A.R.E.S.. Safflower(Cheongsoo cultivar) was seeded at March 1st, April 1st, May 1st, and July 1st in field. The necessary date for germination was 24 days, when safflower was seeded at March 1st, but it was 8 days which sowed at April 1st and when the seed was sowed at high temperature period, the necessary date for germination was getting short. The necessary date for flowering was the same trend as germination; it took 104 days at March 1st, 79 days at April 1st, 65 days at May 1st, and 58 days at July 1st sowing treatment. The safflower growth was the most vigor when it was sowed at March 1st. T/R(Top/Root) ratio was gently increased during growing season, but when the seed was sowed at July 1 st, it was low compare to sowing at March 1st and April 1st. RGR(Relative growth rate) was the highest during shoot growth stage, but it was rapidly decreased after flowering. CGR(Crop growth rate) was increased at branching stage, and the increasing velocity was slightly decreased just before flowering, and it was increased again at flowering and at this stage, CGR was the highest, and then it did not increased. NAR(Net assimilation rate) was the highest at shoot growth stage during growing season, and was the highest which was sowed at March 1st.

Kalopanax pictus was cultured in vitro to find out optimal condition for embryogenic cells proliferation in liquid media rapidly. Embryogenic cells were induced from leaves and petiols of Kalopanax pictus. Optimum culture medium appeared to be a 1/2MS medium supplemented with 2.0mg/L 2,4-D and 0.1mg/L BA. To find out optimal conditions, embryogenic cells were cultured some condition as different concentrations of 2,4-D, medium and sucrose. There was cultured on 1/2MS liquid medium containing different concentration of 2,4-D. When embryogenic cells were cultured on 1/2MS liquid medium supplemented with 1.0mg/L 2,4-D, cell propagation rate was higher than other concentration of 2,4-D. When embryogenic cells were cultured on different media that MS, Gambols B5, N6, White, SH medium, observed the highest multiplication rate among Gambols B5 and White medium. To find out of effect of sucrose to embryogenic cells propagation, we tested cells under different concentrations. Optimal concentration of sucrose appeared to be a basal medium added 3% sucrose. Above results suggest that optimal conditions for proliferation of embryogenic cells were established Gambols B5 and White medium added 1.0mg/L 2,4-D and 3% sucrose. There is every possibility achieving embryogenic cells proliferation via bioreactor culture system in Kalopanax pictus.

Song, Byong-Min ;
Korean Journal of Plant Resources, volume 21, issue 1, 2008, Pages 87~90
The purpose of this experiment is to understand a possibility for the techniques of collecting the Korean Rhus lacquer by the traditional method(Hwachil) against the diminishing lacquer industry. Hwachil method, making use of fire to collect lacquer, is practiced at only some areas, but the lacquer is very efficacious for foods and oriental medicine. A comparative experiment between traditional method and new machine method by processing unit 5 kg of lacquer tree was made to improve Hwachil method technically. The results showed that the machine method produced more about 45% of lacquer than the traditional one. The traditional method, moreover, needed intense labour quality and high leveled techniques, which caused to bring physical sufferings. In comparison with the traditional method for the collecting time required, the machine one showed to take more than minutes per a unit. But the machine method was easy and convenient to handle the machine without special techniques.

Korean Journal of Plant Resources, volume 21, issue 1, 2008, Pages 91~95
Reactive oxygen species(ROS) or free radical-mediated oxidative stress plays an important role in the pathophysiologic process of disease state. This study investigated antioxidative effects of Phellinus linteus extract on the generation of 1,1-diphenyl-2-picrylhydrazyl(DPPH) radical, superoxide anion radical(
), hydroxyl radical(
), nitric oxide(NO), and peroxynitrite(
) radical and free radical-mediated protein oxidation under in vitro assay systems. This results showed that Phellinus linteus extract effectively inhibited the generation of free radicals in the all assay system with dose-dependent manner and also significantly reduced the protein oxidative level. Thus, the present study indicates that Phellinus linteus extract possesses a potent antioxidant activity and plays a beneficial role against free radical-induced oxidative injury.

Nelumbo nucifera Gaertn.(family Nymphaeaceae) has been used for summer heat syndrome as home remedy in Japan, China and Korea. Although whole plant parts are edible, root is commonly consumed. It has been reported that rhizome extract showed anti-diabetic and anti-inflammatory effects. However, in spite of usefulness for treatment of various diseases, the effect of Nelumbo nucifera rhizome(NNR) on proliferation, migration and matrix degrading enzymes-matrix metalloproteinsases(MMPs), the expression of which degrades extracellular matrix(ECM) leading to metastasis, has not been fully elucidated. We examined the effect of hot water extract of NNR on the proliferation, migration and secretion of MMP-2 and MMP-9 in rat smooth muscle cells(rSMC), epidermoid cancer cells(A431) and breast cancer cells(MDA-MB-231). The proliferation assay was carried out using MTT assay, the principle of which depends upon the conversion of MTT by mitochondrial dehydrogensases of viable cells to formazan crystals. The effect of NNR on migration of cells was examined using wound healing assay. Our results showed that there was inhibition in the proliferation, migration and expression of MMP-2 and MMP-9 in dose dependent fashion in all the cells used. Thus, we concluded that NNR could be used as traditional medicine in the treatment of various diseases where proliferation, migration and MMPs' expression plays a pathological role like in restenosis and metastasis.

Korean Journal of Plant Resources, volume 21, issue 1, 2008, Pages 103~109
Nelumbo nucifera root(NNR) is used to clear summerheat(暑熱), bear Yang(陽) upwards and stop bleeding as mentioned in traditional Korean medicine. Also, it has been known that NNR is effective for lowering blood pressure and hyperlipidemia. The rhizome is considered to be nutritive, demulcent, diuretic and cholagogue and is used to treat piles, dyspepsia and diarrhea. An increasingly growing market for nutraceuticals and functional foods has triggered the study on natural sources for nutraceuticals, health foods and functional foods. But rhizome was inconvenient to formulate liquid dosage form(extract) by way of hot water because of its limited storage. Also the majority of the consumers have a complaint against the dosage. The purpose of this study was to develop the functional materials from NNR without side effects. We formulated the solid dosage form viz tablet and granule from the lotus root. Sensory evaluation was performed in terms of smell, taste, color and overall of lotus root and all colored forms(brown, dark brown, light green and yellow) of tablet and granule to evaluate the acceptability of the formulated tablets and granules. In sensory evaluation, among the formulated tablets and granules, light green granules obtained best score overall and yellow tablets showed the overall improved acceptability. In conclusion, lotus rhizome could be recommended as functional food. Further studies to clarify bioactive functions of Nelumbo nucifera in experimental animal model on atopic dermatitis are in progress.
