Study on the Propagation System and the Photosynthetic Rate of Chrysantemum zawadskii H.
Korean Journal of Plant Resources, volume 11, issue 1, 1998, Pages 1~8
This study was conducted to establish mass propagation system from the axillary bud culture of chrysanthemum zawadskii H. which was used as material of medicinal plants. Shoot egeneration was better on MS medium with NAA and BA. The optimum concentraions of growth regulator for shoot regeneration differed depending on accessionsof C. Zawadskii. Shoot regeneration in Keungucheolcho was better on MS Medium with NAA 0.01mg/1 and BA 0.1mg/1 while Hyangrobonggucheocho was better with NAA 0.1mg/1and BA 0.3mg/1. Addition of NAA into medium was effective for induction of root from shoots regenerated. Shoot multiplcation was more effective when 10mg/1 spermine was added into medium than when other polyamines were treated ino medium . Randomly and specifically amplified polymorphic DAC banding patterns based on polymerase chain reaction (PCR) analysis were used to assess the genetic variation of plants regenerated from in vitro culture.
Plant Regeneration through Direct Somatic Embryogenesis from Immature Zygotic Embryo of Prunus yedoensis in Mt.Halla
Korean Journal of Plant Resources, volume 11, issue 1, 1998, Pages 9~14
Two types of somatic embryos were directly induced from the immature zygotic embryos of the wild prunus yedoensis in Mt. Halla after 16 weeks of culture on MS medium supplemented with 0.1mg/L
and 0.1mg/L BAPor 0.5mg/L
and 0.1mg/L BAP. One was normal single embryo with a single basal part. Normal somatic embryos germinated successfully on 1/2 MS medium. However, abnormal nulticotyledonary somatic embryos, formed shoots only on hormone free MS medium and about 80% of shoots rooted on MS medium with 0.5mg/L IBA. The mximum frequency (62.5%) of normal somatic embryos was directly obtained from the zygotic embryo 30 days after full blooming but it was decreased with further maturation.
Effects of Plant Growth Regulators on Callus Formation and Organogenesis of Sicyos angulatus L.
Korean Journal of Plant Resources, volume 11, issue 1, 1998, Pages 15~21
This study was carried out to determine the effects of plant growth regulators on cell culture and organogenesis from Sicyos angulatus L. using explants of leaves, stems and cotyledons. Optimal callus induction for S. angulatus was obtained on MS medium with 0.1mg/
BA and 2.0mg/
2,4 -D from cotyledons, 0.1mg/
BA and 5.0mg/
NAA from leaves explants, Optimal media for subculture and growth of S. angulatus callus were 1/2 MS medium with 0.1mg/
BA and 1.0mg/
2,4 -D for solid culture, and 0.1mg/
2,4-D for suspension culture. Many adventitious roots with some shoots were formed were formed from leaf and cotyledon explants of S. angulatus during callus induction with optimal combinations of plants growth regulators.
Anatomical Study on the "Ggaenggaengipul(Jeffersonia dubia
Korean Journal of Plant Resources, volume 11, issue 1, 1998, Pages 22~29
Korean folk medicine "Ggaenggaengipul" has beenused to dlear heat and treat chronic childfood mutitional impairment, diarrhea, jaundice, haemorrhoid, inflammation, anepithymia, nausea and egestion .The crude drug often used as a supstitute for the more expensive "Huang Lian " (황연) in Korea and China. With regard to the botainicla origic of " Ggaenggaenigipul" , it has never been studied pharmacognostically. To clarify botanical origin of " Ggaenggaegipul" , the morphological and anatomicla characteristics of the leaves, petiole, rhizoma, and radix of Jeffersonia dubia BENTH were studied.
Relationship between cotyledon Number and Vascular System in Carrot Seedling
Korean Journal of Plant Resources, volume 11, issue 1, 1998, Pages 30~39
Carrot seedling emgryos showing variations in cotyledon number were selected and anatomical comparisons of the embryo vascular systems were performed between the variants and normal two cotyledonary (5) embryos from 800 seedings germinated . Externally, all of the four and six cotyledonary embryos had two cotyledonary petioles. Each of the cotyledonary petioles divided into two or three on the upper part fo the petiole which result in four and six cotyledons, respectively. However, the embryos had three different cotyledonary petioles in the three cotyledonary embryos. On the basis of the pattern of vascular system, the four and six cotyledonary embryos had the same basic vascular system as fnormal two cotyledonary embryos, Therefore the cotyledon number abnormality could result from the branching split of the abnormally thickened upper part of the cotyledonary petiole. However, the three cotyledonaryembryos had a different vascular system from the normla two cotyledonary embryos. They could be regarded as different varieties form the two cotyledon embryos. All embryos observed had short cylindrical plumule sheath which formed by the fusion of the cotyledon bases. The presence of plumule sheath strontgly implied that the initiation of the cotyledons was not from the two localized primordia but from the circular proimordiu formed at the blobular stageof embryo, and it is not consistent with current views of cotyledon initiation. On the formation of the primary vascular system of carrot seedlings, it is suggested that the primary vascular system of the plumule was formed independently from that of the root-hypocotyle-cotyledon system.
Comparison of Urushiol Composition and Biological Activity between Fresh Sap and Fire Distilled Sap of Lacquer Tree
Korean Journal of Plant Resources, volume 11, issue 1, 1998, Pages 40~46
For the comparison of the urushiol composition and biological acitivity between the fresh sap and fire distilled sap of lacquer tree(Rhus vernicifera), we analysed the urushiol composition by HPLC and EI-MS, and investigated the antioxidative , antimicrobial and anticancer acitivities according to solvent fractionations. There was no difference in the urushiol composition between fresh and fire distilled saps of lacquer tree. The hexane frqctionsof two saps showed a strong DPPH radical scaverging activity (RC50 : 7.0-7.5
). They also showed a strong antifungal activity onthe spore germination of Cladosporium herbarum(MIC : 8
/ml), whereas they have no or low activity against the bacteria(BAcillus subtilis , Escherichia coli). In addition , hexane and butanol fractions of two saps showed a strong inhibitory activity against cultured tumour cell lines (GI50 : 0.35, 12.29
/ml) in vitro. These results confirm that the fresh sap and fire distilled sap might have the similar urushiol compositions and biological activities.
Comparison of the Composition of Free Sugars , Amino Acids and Minerals in Black Omija (Schizandra nigra Max)
Korean Journal of Plant Resources, volume 11, issue 1, 1998, Pages 47~50
For the quantitiative determination of chemical and taste components in black omija(Schizandra nigra Max) and omija(S.chinensis), compositions of free sugars, free amino acids, total amino acids, and minerals were analyzed. Among the total free sugars in black omija and omija, glucose and frutose were major free sugars and sucrose was little amount. The most abundant free amino acid in black imija was histidine and that in imija was serine. The major free amino acid in black omija and omija were histidine, serine, glutamic acid and aspartic acid. The major total amino acids in black omija and omija were glutamic acid, arginine , leucine and histidine. The limiting amino acid of each omija was S-containing amino acids. The abuntdant minerals in black omija and omija were K and Ca.
Chemical Analysis on Biologically Active Substances among Habitats of Allium victorialis for a High Income Crop
Korean Journal of Plant Resources, volume 11, issue 1, 1998, Pages 51~59
When the contents of the constituents such as total amino acids, free amino acids, volatile organosulfuric compounds and steroidal saponins among three origins in the aerial-and underground parts of Allium victorialis, it was suggested that the characteristic components regarding to quality evaluation could be differed according to the purpose of utilization. For the utilization of amino acids, underground parts of this plant was shown to be better than aerial part. In addition, Ulung island origin was found to contain the highest amino acids content among the three origins though the difference was small. The amino acids showing remarkably high contents were appeared to be arginine, glutamine and asparagine. In the volatile organosulfuric compounds, the origina of Mt. Odae and Mt. Chiri positioned in inland showed higher contents than Ulung island origin geographically positioned in the ocean. Inland origins were shown to contain higher organosulfurie component contents in aerial parts than in underground parts while those of Ulung island origin were higher in underground parts than aerial parts. Underground parts, regarding to saponin constituents, showed higher contents than aerial parts. Underground parts of Ulung island origin were shown to contain more saponins than those of other two origins and the sequence of the contents was in the order of Ulung island>Mt. Chiri>Mt Odac.
Extraction and Analysis fo CArthamin Contained in the Safflower
Korean Journal of Plant Resources, volume 11, issue 1, 1998, Pages 60~63
For the purposed of improving the utilization of natural chemical pigment, carthamin, of Carthamus tinctorius, the effective extraction methods on this compound were pursued in the present study. The best solvent for the extraction was found to be the 1 %(v/v) NaOH solution, at 25 hours. In addition, more carthamin was extracted flowers from main stem than fromb-ranches . The carthamin content of Korean local safflower was shown to be higher than that of Japanese variety used for medicinal uses.
Characteristics of Grain Qualtiy at Different Transplanting Times among Rice Cultivars
Korean Journal of Plant Resources, volume 11, issue 1, 1998, Pages 64~69
This experiment was conducted to investigatd the variation of some apearance chemical components at National Honam Agricultural Experiment Station in Korea. the treatements consisted of five transplating times, form May 5 to July 5 at 15-day interval , and six cultivars ; two early-maturing, two mid-maturing and two latematuring cultivars. The results showed that the variatio of grain appearance such as length-wide ratio was not significantly different in early -maturing cultivars, but mid-and late-maturing cultivars made slightly a round shape of grain in case of early transplanting. Percentage of complete grain was found to be high at transplanting of MAy 20 inearly-maturing cultivars and on June 5 in mid-and late-maturing ones. PERcentage of existed embryo after milling showed high at early transplanting of May 5 for early -maturing cultivars, and at the late transplanting of June 5 in early and late maturing one. The chemical components of rice grain showed high in protein , lipid,ash and amylose content inthe earlier transplanting, and also revealed high in carbohydrates, magnesium and potassium in the later transplanting of all cultivars.
Effects of Climatic Factors and Tapping Date on Yield and Quality of Lactree (Rhus verniciflua) Sap
Korean Journal of Plant Resources, volume 11, issue 1, 1998, Pages 70~79
This study was conducted to understand the effects of weather and tapping date on yield and quality of lactree(Rhus verniciflua) sap yield showed a significant positive correlation with the minimum temperature of one day before sap collection at 1% level and with theminimum humidity of theday of sap collection at 5% level. However, the differences between the maximum and the minimum temperatures and humidities of the day of sap collection were negatively correlated with the sap yield at 5% level. Multiple regression analysis indicated that the minimum temperature of one day bofore sap collection and the minumum humidity of the day sap collection were important factors for increasing sap yield. The high sap yield of lactree by Japanese tapping method was recorded during mid-July and early August. Seasonal variation in lactree sap constituents was observed. The sap collected on 15th of August contained the highest urushiol content (68.3%) and the lowest water content resulting in high quality of lactree sap. By reversed-phase HPLC analysis, fove urushiol components were separated from each other depending on the number of doulbe bonds in the side-chain , and seaxonal variation of urushiol composition was noticed. The 3-C15 triene content fo the sap collected on 5th of July was the highest(77.56%) indicating the major component of urushiol which affects lactree sap quality.
Effects of Elevated
and Global Warming on Growth Parameters, Biomass Production and Its Partitioning of Rice
Korean Journal of Plant Resources, volume 11, issue 1, 1998, Pages 80~85
The influence of elevated CO2 and temperature on growth parameters, biomass production and its partitioning of rice (Oryza sativa L.cv. Chukwangbyeo) were investigated in the three experiments (1991-1993). Rice plants were grown from transplanting to harvest at either ambient(350ppm) or elevated CO2 concentrations (690 or 650ppm) in combination with either four or seven temperature regimes ranging form ambient temperature (AT) to AT plus 3
.From transplanting to panicle initiation, crop growth rate (CGR) was enhanced by up to 27% with elevated CO2 , primarily due to an an increase in leaf area index. although net assimilatiion rate was also greater at elevated CO2. The effect of elevated CO2 varied with temperature. During the reproductive phase, CGR declined linearly with increased temperature, and was greater at elevated CO2 . Elevated CO2 increased final crop biomass and panicle weight 30% respectively at AT(27.6
: 1991) . However, there was no significant effect of elevated CO2 on panicle weight at AT plus 3
, where severe spikelet sterility occurred. There was no significant effect of elevated CO2 on panicle weight at AT plus 3
, where severe spikelet sterility occurred. There was also no effect of CO2 on biomass pratitioning into vegetative and reproductive organs (harvest index)) at AT, although higher temperature could affect that by inducing spikelet sterility. These results suggest that elevated CO2 could enhance rice producivity througth promoted growth and biomass production , but its positive effects may be less at higher temperatures.
Study of Matter Production and Phothsynthetic Characteristics in Wild Vegetable(Chwinamul)
Korean Journal of Plant Resources, volume 11, issue 1, 1998, Pages 86~92
The photosynthetic rate (LPS)in the field was higher in the non-shading condition than in the shading. The fertilizer application was somewhat higher than non-fertilizer application. After humus application at 50% sading condition the growth and LPS increased with Ligularia fischeri. The maximum LPS at 80% shading was 22.3
mol/m/s with N-fertilizer application . Except Aster tataricus and Solidago virge-aurea. var. asiatic where the maximum LPS at non-shading and N-fertilizer application were 38.68 and 35.28
mol/m2/s. While the maximum LPS of Aster scaber was 30.01
/s at non-shading and non-fertilizer application. the growth rate was higher shading and fertilized conditions than non-shading and non-fertilized . The most effective shading condition was 50% , but leaf ration was highest in the 80% . But a. tataricus was favorable at non-shading and N-feritlized conditions.
Studies of Physiological Response to the Salt Tolerance of Rice Cultivars
Korean Journal of Plant Resources, volume 11, issue 1, 1998, Pages 93~100
This study was to investigate the dry weight, the amount of Na+ and K+ water potential and leaf photosynthesis rate in plants for determining the salt tolerance mechanism in rice cultivars on soil and solution culture with NaCl. The results obtained in this study are summarized as follows ; In general, rice cultivars, cv. Tetep and Jinbu, having high salt tolerance in ID(identified on dry matter production level) showed the higher salt tolerance in RGR (relative growth rate), compared with rice cultivars(cv. Nonglim 41ho, Dunraebyeo and Sobackbyeo) having low salt tolerance. The contents of Na in rice differed depending on culivars and plant parts. Tetep contained 2.9times higher amounts of Na+ than leaf blade and root part. High salt tolerance cultivar Obongbyeo showed a larger decrease in osmotic potential than low salt tolerance cultivar Dunraebyeo suggesting that osmotic adjustment was developed under salt stress conditions in a salt tolerant cultivar . In order to know the IY(identified on grain yeild level using rice cultivars having different salt tolerance the capacity of photosyntheiss was investigated. The capapcity of photosynthesis in cv. Tetep and Obongbyeo having high salt tolerance was much higher that in cv.Dunraebyeo and Nonglim 41 having low salt tolerance.

Korean Journal of Plant Resources, volume 11, issue 1, 1998, Pages 101~105
This study was carried out to find out the method of increasing seed germination rate of Dendropanax morbifera LEV. was drupaceous fruit. The length and width of ovarywas 7.8 to 10.7mm, 6.9 to 9.0mm, respectively, and the shape was elliptical. The ovary had 5 loculi with one speed per loculus , but one seed among 5 weeds was exalbuminous seed. The length and width of seed was 6.3 to 7.4mm, 2.0 to2.mm, respectively, and 1,000 seed weight was 14.3 to 18.0g. Seeding after stroring at
for 60 to 90 days was germinated to 87% . However, fall seeding directly after harvest was increased to 85% at hot-water treatement (
) for 90 to 120 minute.

Korean Journal of Plant Resources, volume 11, issue 1, 1998, Pages 106~110
The present study has been undertake to obtain the fundatmental data of optimum germination condition and to establish storage time for artificial pollinationin Codonopsis lancelata pollen. In vitro condition for germination of freshly collected and stored pollen were examined. The optium temperature for germination of fresh pollen was
. The optium sucrose concentration in the medium ranged from 30 to 40 % and optium pH 6.0% for pollen germination. The rate of pollen germination accelerated considerably in the medium with 1% agar. 30% sucrose, and pH 6. C. lanceolata pollen remained viable for 15 days when stored at 5
with silica gel as desiccant.
Effect of Chitosan on Storage Stability of Nabak Kimchi
Korean Journal of Plant Resources, volume 11, issue 1, 1998, Pages 111~117
The effect of chitosan on physicochemical and organoleptic properties of Nabak kimchi was studied during fermentation at 2
. Viscosity of the juice of Nabak kimchi added with chitosan was lower than that of control group. The viscosity was gradually increased during storage period, especially from 5 days to ,7 days of storage. Initial pH was higher in control group than inchitosan groups. The pH of controlgroup decreased rapidly during 4 days of storage. The pH of chitosan groups was slightly increased during the first 3 days of storage and decreased thereafter. Acidity was rapidly increased from 3 to 5 days. Reducing sugar contents increased up to 3 days and decreased thereafter. Acidity was rapidly increased from 3 to 5 days. Reducing sugar contents increased upto 3 days and decreased therafter. Glutamic acid, alanine, threonine, aspartic acid, proline and valine were the major free amino acids, and as the fermentation preceeded they were increased gradually. There were signigicant differences in saltiness, sourness and aged odor in sensory evaluation of Nabak kimchi solution during fermentation at 2
