Effects of Presowing Seed Treatments on Improvement of Seed Germination and Seedling Emergence of Onion
Korean Journal of Plant Resources, volume 17, issue 3, 2004, Pages 219~226
Transplantings of onion (Allium cepa L.) seedlings are required for higher germinability and uniformity. This study was done to determine effects of various seed treatments (seed cleaning, priming, GA
, prechilling, drying, and light quality during seed drying) on germination and seedling emergence. Nongwoodaego and Changnyungdaego were used as cultivars for checking seed germination, and two cultivars and Cheonjuguhyeonghwang were investigated with seedling production rate. Seed cleaning using water prior to the other treatments greatly increased germination rate. Priming with 200mM Ca(NO
solution somewhat alleviated the germination rate while GA
did not. Prechilling had the highest rate among the treatments. Seed drying after prechilling enhanced the rate compared to non drying, and during drying the prechilled seeds red light illumination showed the greatest rate in comparison with dark, blue, and far-red ones. Seedling production rate was enhanced in sequential treatments of seed cleaning, prechilling for 3 to 5 days, and red light treatment during 6 hour seed drying.
Genetic Variation of Rhododendron micranthum Based on AFLP and RAPD Analysis
Korean Journal of Plant Resources, volume 17, issue 3, 2004, Pages 227~238
Rhododendron micranthum is an endangered species in Korea. In order to develop the strategy of gene diversity conservation, estimation of the amount of genetic diversity, the genetic variation and relationship in the native populations of Rh. micranthum was performed on the basis of AFLP and RAPD analysis. Analysis of 56 accessions derived from 6 populations of Rh. micranthum with four AFLP primer combinations and ten RAPD primers detected a total of 33 polymorphic AFLP fragments and 15 polymorphic RAPD fragments, respectively. By UPGMA cluster analysis with molecular markers, the 56 accessions were grouped into three major clusters at 73.3% genetic similarity; group I consists of most accessions of populations I, II, IV, V and Ⅵ, group II consists of 7 accessions of population III, and group III consists of only two accessions of population IV. The geographic locations of the most accessions derived from six populations were not related to their position in the UPGMA cluster analysis, except for several accessions of populations III and IV. The genetic similarity of among six populations measured by AFLP and RAPD markers ranged from 0.66 to 0.99. Among them, population Ⅵ showed the highest GS with means of 0.87, while population I showed the lowest GS with means of 0.78. This result will be useful for designing the strategy of conservation in the native populations of Rh. micranthum.
Isolation and Characterization of Cyclophilin 1 (ClCyP1) Gene from Codonopsis lanceolata
Korean Journal of Plant Resources, volume 17, issue 3, 2004, Pages 239~247
A cyclophilin 1 cDNA clone(GenBank accession no.CF924191) was isolated from the taproot of C. lanceolata and designed as C1CyP1. Determination of the nucleotide sequence of C1CyPl identified an open reading frame of 525bp, which shared high homologies with cyclophilins that were previously reported in other organisms. The C1CyP1 amino acid sequence possesses 7 amino acid residue stretch(KSGKPLH) that is characteristic of plant cytosolic dehydrins. Currently available amino acid residues of plant cyclophilins were compared to examine their phylogenetic relationship to C1CyP1. In the phylogenetic analysis, based on the aligned sequences, C1CyP1 showed high homology with arabidopsis ROC2 and rice CyP1. The transcript that corresponded to C1CyP1 was abundant in callus, but only basal level of transcript was detected in stem, leaf and root. For the study in the defense mechanism against various stresses, we report expression patterns of this gene by quantative RT-PCR.
Population Structure and Growth Dynamics of Dendropanax morbifera Lev.(Araliaceae) in Mt. Halla
Korean Journal of Plant Resources, volume 17, issue 3, 2004, Pages 248~256
Dendropanax morbifera Lev.(Araliaceae), Korean endemic and evergreen small tree is a component of evergreen forest and mainly distributed in sourthern region and islands in Korea. The ecological characteristics of 4 natural stands of D. morbifera.(Sundol, Suak, Hannam, and Sangho populations in Cheju island) were studied. In most of the D. morbifera natural stands, the following tree species appeared predominantly: Castanopsis cuspidata var. sieboldii, Carpinus laxiflora, D. morbifera, Quercus glauca, Quercus myrsinaefolia, Camellia japonica, and Acer pseudo-sieboldianum. Two tree species, such as C. cuspidata var. sieboldii and C. laxiflora appeared in the all investigated stands. D. morbifera occupied 17.2% of the upper story, 12.9% of the middle story, and 10.3% of the lower story, respectively. The distribution patterns by Morisita' s Index showed that D. morbifera was distributed randomly in the three stories. The frequency distribution of DBH D. morbifera species showed reverse J-shaped, therefore it seems to remain as a dominant species.
Selection of Ginseng Superior Lines Tolerant to Salt Stress Through Zygotic Embryo Culture
Korean Journal of Plant Resources, volume 17, issue 3, 2004, Pages 257~264
Selection of stress-tolerant ginseng lines in fields is very difficult because it is almost impossible to control properly the environmental conditions of soil. On the contrary, it can be studied with ease to search for stress-tolerant ginseng lines through in vitro culture because of easy manipulation of stress conditions. This study was conducted for the selection of ginseng pure lines tolerant to salt stress. Murashige ＆amp; Skoog(MS) media with 2.5 folds of KNO
, and CaC1
was established for the selection of ginseng pure lines tolerant to salt stress in vitro. Among 88 ginseng pure lines bred by Korea Ginseng and Tobacco Research Institute, Punggi Hwangsuk, 78093, 82886, 78135, 86024 and KG104 lines was tolerant to salt stress. For the stable production of quality Korean ginseng, genetic tolerance to salt stress is one of important factors since relatively high salt concentrations in the ginseng nursery soil environment of Korea. Ginseng inbred pure lines were tested for their tolerance to salt stress through in vitro culture technique.
Diversity and Inheritance of AFLP Markers in Wild and Cultivated Soybeans
Korean Journal of Plant Resources, volume 17, issue 3, 2004, Pages 265~271
Genetic variation is the basis of crop improvement. Limited genetic diversity in a crop species may restrict the amount of genetic improvement that can be achieved through plant breeding. Soybean is one of the world's most important crops. A potential source of genetic variability for the cultivated soybean is the wild species G. soja Sieb. ＆amp; Zucc. Amplified fragment length polymorphism (AFLP) analysis is a PCR-based technique, which can detect a 10-fold greater nubmer of loci than other DNA marker analysis. Twenty cultivated soybeans and two-hundred wild soybeans were used to determine genetic vatiations by AFLPs and evaluate the usefulness of AFLPs as DNA markers. Six-hundred and ten fragments were detected with an average of 56 AFLP fragments produced per primer in a total of 11 AFLP primer pairs. The number of polymorphic loci detected per primer ranged from 7 to 20 and the polymorphism was greater in wild than in cultivated soybean. F
segregation analysis of four AFLP fragments in combination of Hwaeomputkong
PI 417479 indicated that they segregate as stable Mendelian loci with 3 : 1. This results strongly suggest that the AFLP analysis is a good technique for the detection of genetic polymorphism in a wide plant species.
Effects of BA and NAA on Adventitious Shoot Formation from Mature Zygotic Embryos of Stewartia koreana Nakai
Korean Journal of Plant Resources, volume 17, issue 3, 2004, Pages 272~277
Zygotic embryos of Stewartia korean Nakai were cultured to determine the effects both of BA and NAA on adventitious shoot induction. Multiple shoots (about 11 per explant) were formed when the embryos were treated with 1.0 mg/L BA alone. On the other hand, NAA appeared to inhibit shoot induction when treated with BA. Adventitious shoots looked differ in form and color by the combinations of BA and NAA treated. When both BA and NAA were present, the shoots became short and developed dark color. The highest rooting was observed at 0.5mg/L NAA. The results could be useful for the establishment of in vitro regeneration system for Stewartia koreana Nakai.
Antimicrobial Activity in 2 Angelica Species Extracts
Korean Journal of Plant Resources, volume 17, issue 3, 2004, Pages 278~282
We investigated antimicrobial activity of methanol extract from Angelica gigas and A. acutiloba against three gram-positive bacteria(Bacilius cereus, B. subtilis, and Staphylococcus aureus), two gram-negative bacteria (Escherichia coli and Pseudomonas fluorescens), and one yeast (Saccharomyces cerevisiae). The antimicrobial activity was shown in only ethyl acetate fraction of shoot and root extracts from A. gigas. The activity of the fraction of shoot extract was remarkably potent against S. aureus. The ethyl acetate fraction of root extract showed great antimicrobial activity against B. subtilis and E. coli. The n-hexane fraction of shoot extract and the water fraction of root extract from A. acutiloba were not showed antimicrobial activity, in contrast, the ether fraction of shoot and root extracts showed great antimicrobial activity. S. cerevisiae was not inhibited by any fractions and species.
Effect of Siho (Bupleurum falcatum L.) Extracts on Liver Function in
Korean Journal of Plant Resources, volume 17, issue 3, 2004, Pages 283~288
Effect of Siho (Bupleurum falcatum L.) extracts on liver function were investigated in CCl4 intoxicated rats. Plasma
-fetoprotein and total protein concentration showed a tendency to decrease in Siho extracts groups. However plasma albumin concentration showed no significantly different in all treatment groups. Activities of plasma asparate aminotransferase and alanine aminotransferase in Siho extracts groups showed a lower values than control group. Alkan phosphatase and lactate dehydrogenase activities showed a tendency to decrease in Siho extracts groups. However
-glutamyl transferase activity showed no significantly different in all treatment groups. Concentration of plasma triglyceride and total cholesterol showed no significantly different in all treatment groups.
Isolation and Expression of Aluminum Induced Protein(ClAIP) Gene from Codonopsis lanceolata
Korean Journal of Plant Resources, volume 17, issue 3, 2004, Pages 289~296
A cDNA clone (GenBank accession no. CF924621) homologous to aluminum induced protein gene was isolated and characterized from Codonopsis lanceolata (ClAIP). The ClAIP is 906 nucleotides long and has an open reading frame of 711 bp with a deduced amino acid sequence of 236 residues. The ClAIP shows high homology to A. marina (84%), G. hirsutum(83%), V. radiata (83%), A. thaliana (80%), B. nap us (78%) and T. aestivum (68%). The deduced amino acid sequence of ClAIP also has homology to the N-terminal end of plant Asn synthetase. This region does not contain the active sites of the enzyme and the significance of this conservation is currently not clear. To investigate the expression of ClAIP against several heavy metal stresses, we treated the sliced tap root of C. lanceolata with various heavy metals. The expression of ClAIP was increased by 25 uM
in proportion to incubation time and also increased by 50 uM CdCl
Dyeability of Ramie Fabrics Using Extract of the Native Plant of Rubia akane Nakai Grown in Korea
Korean Journal of Plant Resources, volume 17, issue 3, 2004, Pages 297~303
This study was carried out to investigate into the dyeability of ramie fabrics using the extract of native plant, red-dye madder (Rubia akane Nakai) in different conditions. Surface color of ramie fabrics dyed with extracts from red-dye madder plants showed an order of descent YR. However, it was changed by the different mordants. Surface color of ramie fabrics treated with FeSO
, and tartaric acid was an order of descent Y, and that treated with the ashes of common camellia, and bean straw was an order of descent R. At higher temperatures, surface color and coloring matter concentration of ramie fabrics were as follows that values of a increased, however, values of b decreased and values of L lowered. Coloring matter concentration increased in the order of 7
, and 6
, and so on. Dyeing colors on the ramie fabrics showed an order of descent Y by pH 4 and 9 in dyestuffs solutions. Coloring matter concentration in terms of K/S values, more or less, was increased at strong acids. Surface color by the concentration of dyestuffs solutions showed an order of descent YR irrelevant to the concentration of dyestuffs solutions. Coloring matter concentration was increased at higher concentrations of dyestuffs solutions. Ten minutes was sufficient for the dyeing of ramie fabrics in terms of surface color and coloring matter concentration.
Genetic Studies of Major Agronomic Traits in Hybrid Populations of Maize Inbred Lines.
Korean Journal of Plant Resources, volume 17, issue 3, 2004, Pages 304~313
This study was conducted to find out the scientific maize breeding protocol for developing high performing single cross hybrid using introduced U.S. elite inbred lines; the pattern of inheritance, heterosis and heritabilities of six agronomic traits were studied in the progenies derived from five crosses (Mo17/B14A, Va85/B73, C103/ND203, FR35/Oh43, Wf9/A632). Among the five cross combinations, the cross combination of Mo17/B14A showed the highest heterosis for the most agronomic traits. Among 6 agronomic traits, the grain yield showed the highest heterosis effect in most cross combinations. Most of the agronomic traits in this study showed more than 50% heritability for six cross combinations, with an exception of the ear length trait. In conclusion, since Mo17/B14A showed excellent performance for most of the agronomic traits, these inbred lines were desirable combination and regarded as superior germ plasm sources for F1 hybrid development. The results of current studies will be utilized for developing high performing single cross hybrid from maize inbred lines, and will be used for the further genetic analysis of agronomic traits and maize breeding programs.

Korean Journal of Plant Resources, volume 17, issue 3, 2004, Pages 314~322
This research has been undertaken to increase availiability of native Camellia japonica leaf and flower in Korea as a edible-medicinal resource. Chemical compositions, antioxidant and antimicrobial activities in different parts of camellia were investigated. Crude protein contained the highest in young leaves(14.22%) but less than 10% in different parts. The contents of crude fat and crude ash were 60.48% in seeds and 5.16% in mature leaves, respectively. Methanol extract of young leaf, flower, and flower bud in camellia showed strong antioxidant activity compared with different parts. Also, antioxidant activity of these was higher than that of BHT, but weaker than that of VtC. Antioxidant activity of various parts in camellia were in order of young leaf ＆gt; flower bud ＆gt; flower ＆gt; mature leaf ＆gt; stem ＆gt; bark. Extracts of mature leaf and bark had a remarkable antibacterial activity(0 CFU/
) on Bacillus subtilis. The young leaf extract displayed effective growth inhibition against B. subtilis, Candida albicans, and Trichosporon beigelii.

Korean Journal of Plant Resources, volume 17, issue 3, 2004, Pages 323~330
Effects of Guemengja (Rosae Laevigatae Michx.) Extracts on serum and liver lipid composition and antioxidative capacity were investigated in rat fed high oxidized fat. Twenty eight male Sprague-Dawley rats weighing 159.35
2.17g were blocked into four groups according to body weight and raised seven weeks with basal diet (normal group, I), basal diet and 10% oxidized fat (control group, II), basal diet, 10% oxidized fat and 100mg/kgg Guemengja Extracts (100mg/kg Guemengja Extracts group, III) and basal diet, 10% oxidized fat and 200mg/kg Guemengja Extracts (200mg/kg Guemengja Extracts group, IV). The level of plasma total cholesterol and triglyceride showed a tendency to decrease, whereas the plasma HDL-cholesterol concentration revealed a tendency to increase in guemengja extracts groups. The level of liver total cholesterol showed no significantly different in all treatment groups, however the level of liver triglyceride showed a tendance to decrease in guemengja extracts groups. Thiobarbituric acid(TBARS) values in plasma and liver showed a tendence to decrease in guemengja extracts groups. The guemengja extracts samples have also decreased the plasma GOT and GPT activities, whereas they have increased the liver glutathione peroxidase, superoxide dismutase and catalase activity.
Virus free Healthy plant production through Meristem culture in carnation (Dianthus caryophillus)
Korean Journal of Plant Resources, volume 17, issue 3, 2004, Pages 331~338
This study was conducted to obtain the virus free plants through meristem culture of carnation (Dianthus caryophillus). Four cultivars (Roland, Desio, Casha, Giant Gipsy) were collected for materials. The apical meristem 0.3-0.5mm in size was cultured on MS medium containing 3% sucrose, 0.9% agar at pH 5.8 with various plant growth regulators for 7 weeks. Among the cultivars, Giant Gipsy had a better response than other cultivars in shoot formation and reduced vitrification. Callus induction and shoot formation from the meristem culture were influenced by the various kinds of cytokine. Kinetin supplement was the most effective for shoot formation and NAA addition was good for callus induction among the treatments. Total 115 plantlets derived from apical meristem culture were checked for CarMV and CarRSV infection by ELISA test. Among them, 40 plantlets (34.8%) were infected with CarMV but not detected for CarRSV.

Effects of Temperature and Photoperiod on the Growth of Tatary Buckwheat(Fagopyrum tataricum)
Korean Journal of Plant Resources, volume 17, issue 3, 2004, Pages 352~357
This study was carried out to investigate the effects of temperature and photoperiod on the growth of Fagopyrum tataricum. It showed a tendency to promote the germination rate and plant height of tartary buckwheat under high temperature. Plant height and number of leaves were promoted in the order of 25 ＆gt; 20 ＆gt; 15 ＆gt; 3
under the different temperature after 30 days of the planting. In the 10, 12, 14hr photoperiods at 2
, plant height, number of leaves and dry weight were increased as much as photoperiod became long except by 16hr. Rutin contents was not regular both common and tartary buckwheat under the photoperiods. The rutin content in leaves was higher than stem. Compared to yield of tartary and common buckwheat, plant height, number of leaves, number of branch and stem diameter of tartary buckwheat increased more than common buckwheat. Especially, number of leaves was increased about 2.5 times more than common buckwheat. And there was a difference in about 2.1 times in grain weight and about 5.4 times in number of grains. Rutin content was 1469.8mg/l00g in grain of tartary buckwheat. It was about 60 times higher than 22mg/100g in grain of common buckwheat.
