Atopic dermatitis is a chronic, allergic inflammatory skin disease that is accompanied by pruritic chronic eczema and markedly increased levels of inflammatory cells in endothelial cells. Arctium lappa L. is a popular edible vegetable cultivated in Asia. This study examined the effect of butanol extracts of A. lappa (ALBE) on the expression of adhesion molecule, ICAM-1 and the production of NO-iNOS induced by TNF-alpha in A549 endothelial cells. We also studied the effects of ALBE on the proliferation of keratinocyte. We observed significant inhibition of NO-iNOS production in dose-dependant manners and ALBE at
/mL suppressed the expression of ICAM-1 in TNF-
-induced A549 cells. In addition, the treatment of ALBE for 48 hrs increased the proliferation of HaCaT keratinocytes. These results support that ALBE has an anti-inflammatory effects for the treatment of atopic dermatitis.

This study was conducted to determine the effects of scarification temperature, and sulfuric acid treatments on seed germination of white lotus collected from the Muan districts, Jeonnam in Korea. Without scarification, white lotus seeds were not germinated at all at 15 days after seeding. However, seeds sacrificed at basal parts showed 100% germination rate at
6 days after seeding. All the seeds floated (0.90 g) and soaked (1.18 g) in the water were completely germinated. Especially, the lotus seeds soaked in the water at
showed high germination rate. Seeds treated with 80% sulfuric acid for 40-160 hours were germinated completely within 6 days after seeding. No difference in seed germination rate of white lotus stored up to 0, 12 and 24 months after harvest was observed. Overall results would be useful means for propagation and production of white lotus.

DOI : 10.7732/kjpr.2012.25.1.014
This study was performed to investigate the effects of storage, temperature, and pre-treatments on the germination of Melia azedarach seeds collected from Buan, Jeonju, and Jeju provenance. M. azedarach seeds stored with or without pericarp in the ground, which collected from Buan provenance evidenced the highest germination percentage (PG, %) and the shortest time to first germination (days). The seeds collected from Jeonju and Jeju provenance were placed at both six continuous temperatures (15, 20, 25, 30, 35, and
) and two alternating temperatures (
) for seed incubation. The results showed a significant effect for temperature of seed incubation. The seeds incubated at
had the highest PG among the continuous temperatures and germinated significantly more at the two alternating temperatures than at
. Concerning mean germination time (MGT), the seeds incubated at
evidenced the shortest germinations among the continuous temperatures while those at the alternating temperatures germinated for a shorter period than those at
. The germination rate (GR) and germination performance index (GPI) were similar to PG. The seeds collected from Jeonju provenance were treated using five pre-sowing treatments (scarification, scarifcation+
) prior to the germination experiments. Compared with the intact seeds (control), most of the pre-treatments were significantly (especially scarification+
100 ppm and scarification+
1.0%) higher in PG, GR, and GPI, as well as shorter in MGT.

Naehanyuchae and Youngsanyuchae were originated from the cross between "Erra(female)" and "Tower(male)". The cultivars were made at Bioenergy Crop Research Center, National Institute of crop science, Rural Development Administration, Korea in order to develop the high cold tolerant and yielding rapeseed variety with non-erucic acid and non-glucosinolate as good seed quality indicator. The superiorities of these varieties have been shown through the regional performance trials and demonstration farmers fields. Naehanyuchae and Youngsanyuchae had good agronomic characteristics related to yield potential such as many valuable branches and pods, and long pod length. The seeds of these new varieties composed of the 80% of oleic acid and linoleic acid without erucic acid, and glucosinolate was not extracted in the oil cake. The average grain yields increased by the from 16% to 22% according to the regional performance trials compared to check variety.

To assess parameters of mating system in seed orchard, such as outcrossing rates, number of potential pollen contributors, and degree of pollen contamination, seeds, produced in '77 plot of the Japanese red pine (Pinus densiflora S et Z) seed orchard at Anmyeon island, were collected in 2007 and analysed by nSSR and cpSSR markers. Estimates of outcrossing rates ranged from 91.2 to 100% (mean 97.7%) on the basis of the analysis of cpSSR haplotypes and from 81.6 to 100% (mean 95.3%) on the basis of the analysis of nSSR genotypes. By cross checking of both DNA markers, seeds, presumed to be products of self pollination on the basis of single marker, were confirmed as outcrossed seeds, which resulted in cumulative outcrossing rates of 98.9%. On the basis of pooled cpSSR haplotype of each seed, the number of pollen contributors and paternal contribution rates were estimated as 14.8 and 0.512, respectively. In conclusion, considering pretty high level of outcrossing rates observed in a seed orchard, good genetic potential of the seeds, produced in '77 plot of the seed orchard of Japanese red pines at Anmyeon island, may be guaranteed. Investigated results from the analysis of mating system of Japanese red pines in a '77 plot of the seed orchard may also be expected to provide useful information for the management and establishment of the seed orchard of the progressive generation.

Vaccinium oldhami Miq. is a Korean native tree, which is deciduous and shrub tree with broad leaf. It grows 1~4m in height generally. Ecologically, this tree grows well in shady place even in barren soil. Also, the tree has resistance to cold and dry, which tend to form a little community. This research investigates quantitative morphological characteristics of leaf and fruit among the V. oldhami in South Korea and then considers its relationship on the basis of raw data among the 10 populations. This study will give us invaluable information about growing conditions, reasonable management and breeding by selection of V. oldhami in South Korea. The main results obtained from this study are summarized as follows; Leaf size of Mudeung population was larger than other populations. Naebyeon population was smaller in size of the leaf than other populations. Anmyeondo population was larger in fruit characteristics compared with other populations and Deogyu population was the smallest among populations. According to cluster analysis based on the leaf and fruit morphological characteristics, the natural V. oldhami populations were classified into four groups such as the first group of Kumo population, the second group of Mudeung population, the third group of Anmyundo, Daedun, Doolyun population and the fourth group of the other five populations.

DOI : 10.7732/kjpr.2012.25.1.080
This study was conducted to clarify the antimicrobial effects and radical scavenging activities of the cosmetic compositions having the natural plant pigments, and to enhance the natural materials utilization of cosmetics. The antimicrobial activities of the fifteen kinds of cosmetic composition having natural plant pigments were evaluated using the agar diffusion method. Most of the cosmetic composition having the natural pigments showed the clear zone formation of growth inhibition against Bacillus subtilis, Staphylococcus aureus, Listeria monocytogenes, Vibrio parahaemolyticus and Aspergillus flavus. Especially, purple sweet potato, bitter melon, mulberry leaf and gromwell showed the higher antimicrobial activities. All the cosmetic compositions were evaluated for their antioxidant activity using DPPH radical scavenging capacity and nitrite scavenging ability activity. Both of the free radical DPPH and nitrite scavenging ability was the highest in the cosmetic compositions of onion peel, and these antioxidant activity was significant differences according to different plant pigments. In this study, we conjectured that the plant pigment had the potent biological activities, therefore these plant resources having functional components could be a good materials for development into source of natural cosmetics.

Korean Journal of Plant Resources, volume 25, issue 1, 2012, Pages 96~104
DOI : 10.7732/kjpr.2012.25.1.096
Phylogenetic analyses were conducted to evaluate relationships of 7 taxa of Korean Carpesium including three outgroup (Inula britannica L., Inula germanica L., Rhanteriopsis lannginosa (DC.) Rauschert) by using ITS (internal transcribed spacer) sequences of nuclear ribosomal DNA. Phylogenetic studies used maximum parsimony, neighbor-joining and maximum likelihood methods analysis. The length of the ITS sequences was 731 bp, and the lengths of the ITS1, ITS2 and 5.8S regions were 284~297 bp, 264~266 bp and 164 bp, respectively. The total number of variable sites was 111 for the entire sequences, and a parsimony informative sites of 64 are valid. Base change appeared variously in ITS1 rather than in ITS2. As the result, Korean Carpesium were formed monophyletic group and C. abrotanoides situated as the most basal clade. The results show that C. macrocephalum is closely related with C. triste. C. rosulatum has the closest relationship with C. glossophyllum. C. cernuum is close to C. divaricatum. These results suggest that the ITS data used in this study could be useful for the phylogenetic analysis of Korean Carpesium.

This study analyzed on the characteristics of community structure, species composition, population conditions and annual mean radial growth of Taxus cuspidata in the subalpine zone of the Seoraksan, Deokyusan, and Hallasan National Parks. Deokyusan and Hallasan sites had three layers of stratification structure without tree layer in it and four layer in Seoraksan site. The major dominant species in the order of importance value were as follows: T. cuspidata, Acer tschonoskii var. rubripes, Quercus mongolica, Abies koreana and Sorbus commixta. The trees (> 5 cm DBH) of T. cuspidata were extremely high with 986.0 individuals/ha at the Hallasan site. Average DBH class were 42.0 cm at the Hallasan site and mainly showed large class. The populations of seedlings and saplings with 357.3 individuals/ha, and juvenile with 128.6 individuals/ha, as a succession tree, were found to be the highest at the Hallasan site. In the size frequency distribution, the populations of T. cuspidata in Mt. Halla site showed a reverse J-shaped curve and it was estimated that T. cuspidata community of this site might be maintained continuously as a stable state like present state. Annual mean radial growth of T. cuspidata populations at Seoraksan, Deokyusan, and Hallasan sites showed up as 1.27 mm/year, 0.93 mm/year and 0.89 mm/year respectively.

Choi, Chung-Ho ;
Korean Journal of Plant Resources, volume 25, issue 1, 2012, Pages 132~141
DOI : 10.7732/kjpr.2012.25.1.132
This study was carried out to test seed germination responses to temperatures and pre-treatments in Hippophae rhamnoides, which has many abilities in antioxidant activity, soil improvement and erosion control. H. rhamnoides seeds were placed at 10, 15, 20, 25, 30 and
under light condition. As the results, germination percentage (GP) was the highest at 15 and
, and mean germination time (MGT), germination rate (GR) and germination value (GV) were the highest at
. Quadratic and linear regression model were used to determine the cardinal temperatures such as base (
), maximum (
) and optimum (
) temperature for germination. In quadratic regression model using PG,
was estimated as 0.6, 36.4 and
, respectively, and temperature range for germination was
. In linear regression model using GR,
was estimated as 8.3, 35.4 and
, respectively, and temperature range for germination was
. Germination properties were investigated after H. rhamnoides seeds were treated by prechilling (1, 2, 4, 6 and 8 weeks), stratification (2, 4, 6 and 8 weeks), solid matrix priming (seed : carrier : water = 5 : 1 : 7, 8, 9 and 10), osmo-priming (-0.25, -0.5, -1.0 and -1.5 MPa) and calcium chloride (
) -priming (100, 200, 300 and 400 mM). The highest GP was observed in
300 and 400 mM treatments, and MGT was the shortest in stratification 6 and 8 weeks treatments. GR and GV were the highest and GP was the second highest when seeds were prechilled for 1 and 2 weeks. Consequently, prechilling 1 or 2 weeks treatment was considered as the appropriate method when we contemplate qualitative and quantitative effects in seedling production.

This study was carried out to evaluate genetic variation of early-heading rice (Oryza sativa L. cv. Dongjin 1) lines derived from gamma-ray (
, 300 Gy) irradiation. The average heading date of the 5 early-heading lines in
generation was faster than that of untreated control as 11 (line
-2), 10 (line
-5), 6 (
-1 line), 5 (
-3) and 4 days (line
-4), respectively. According to ISSR analysis, polymorphic rate of the early-heading lines (from 5.9% to 23.4%) was higher than that of control (4.3%). The result indicates that the gamma-ray promote variation at DNA level. When genetic variations of rps16-trnK region were evaluated by nucleotide analysis, nucleotide length of the rps16-trnK region was 664 bp in all the early-heading lines and control. Out of 5 sites of nucleotide transposition detected in the region, however, 2 sites were appeared only in the early-heading lines.

Chrysanthemum is a cut flower species that normally lasts for 1 to 2 weeks, in some cases 3-4 weeks. This has been attributed to low ethylene production during senescence. Reduction in cut flower quality has been attributed to the formation of air embolisms that partially or completely blocks the water transport from the vase solution to the rest of the cut flower stem, increasing hydraulic resistance which may cause severe water stress, yellowing, wilting of leaf, and chlorophyll degradation. Standard type chrysanthemum can be harvested when buds were still tightly closed and then fully opened with the simple bud-opening solution. Standard type chrysanthemum can also be harvested when the minimum size of the inflorescence is about 5-6 cm bud which opened into the first flower full-sized flower. While spray varieties can be harvested when 2-4 most mature flowers have opened (40% opening). Cut flowers are sorted by stem length, weight, condition, and so on. Standard chrysanthemum is 80 cm length for standard type and 70cm for spray type. Pre-treatment with a STS, plant regulator such as GA, BA, 1-MCP, chrysal, germicide, and sucrose, significantly improved the vase life and quality of cut flowers. It is well established that vase solutions containing sugar can improve the vase life of cut chrysanthemum. Chrysanthemum is normally packed in standard horizontal fiberboard boxes. Chrysanthemum should normally be stored at
. Precooling resulted in reduction in respiration, decomposition, and transpiration activities as well as decoloration retardation. There was significant difference between "wet" storage in 3 weeks and "dry" storage in 2 weeks. In separate pulsing solution trials, various germicides were tested, as well as PGRs to maintain the green color of leaves and turgidity. Prolonging vase life was attained with the application of optimal solution such as HQS,
, GA, BA and sucrose. This also retarded senescence in leaves of cut flower stems. Fresh cut chrysanthemum can be transported using a refrigerated van with
. Increasing consumption and usage of cut chrysanthemum of various cultivars would require efficient transport system, and effective information exchange among producer, wholesaler, and consumer.
