Resistance Reaction of the Seedlings on Powdery Mildew in Durum Wheat Trisomics Plants
Korean Journal of Plant Resources, volume 11, issue 3, 1998, Pages 245~251
Test plants with 10 days old primary leaves were indouclated by shaking infected seedlings with sporulating colonies over them in an inoculation room under the conditions of 20
with constant illumination of 2.500 lux and 100% realtive humidity. A seeding reaction of 4 days after inoculation appreared in the trisomic types as opposed to Tri-5B line had been symtoms of a fungus 3 days after inoculation. The infection types of 8 days after inoculation were recognized with higher susceptibility to each trisomics in A genomie than B-genome. Tri-2A line showed less condium and there appeared symptoms of a conditions of mottle and formed papilla, and haustorium was not formed. However, Tri-5B line had much condium one overall leaves and showed a symtom like necrosis compared with normal plant. Moreover, Tri-5B line showed high sensitivity and high germination number of condium. These results inferred that resistant gene located on 2A chromosome and susceptibility gene is located on the chromosome 5B.
A Comparison of Microtuberization Efficiency between Normal and Adenosine Deaminase Transgenic Potato Plantlets Cultured In Vitro
Korean Journal of Plant Resources, volume 11, issue 3, 1998, Pages 252~256
A Study was conducted to investigate comparison of in vitro tuberization between normal and transgenic potato plantlets harboring adenosine deaminase gene in potato cultivar of Desiree. In time course study of in vitro tuberization, the rate of tuberization in four lines were increased till 6 weeks. but maintained stil after 7 weeks. Microtuber initiation of transgenic lines, 43 and 39 were faster than other lines, but no difference was observed after 5 weeks compared with normal plantlets. In all transgenic lines, the majoirty of microtubers produced were small(less than 100 mg) and medium(100-200mg) size rather than large size(more than 200 mg). Among 4 lines , line 9 produced the highest number of microtubers per each culture vessel. The results of this experiment suggest that there is no significant difference in microtuber production efficiency between normal and transgenic potatoes.
Evaluation on the Contents of Antioxidative Substance at the Different Layers in Several Rice Varieties
Korean Journal of Plant Resources, volume 11, issue 3, 1998, Pages 257~263
Fifteen varieties of Oryza sativa mainly includig those of Korean native rice were exactly cutted into three layers such as L
layer (the outer part of 90% from rice center), L
layer(the part of 81 ~ 91% from the rice center) and L
layer(the inner part of 80% from the rice center) and ferulic acid derivatives, which play an important role of antioxidative action, were quantitiavely analyzed by UV absorption spectrometric method at fixed 314nm. From this experiment, it was found that the more it enters from the surface into the rice center, the more those secondary metabolites contents were highly reduced. The varieties showing contents more than 20 mg/g were as follows: Hwasunchalbyeo(25.8mg/g), Jojeongdo(24.1mg/g), Suwon425(21.2mg/g), Daigolbyeo(20.6mg/g) and Nonglimna 1(20.2mg/g) by this order. Estimation onthe anthocyanin contents of both Suwon 425 and Sanghehanghyeolna revealed that its total. contents were very exactly close each other. However, it was charateristically differentiated in the contents of L
layer with respect to showing a considerably higher content of Suwon 425 than of Sanghaehanghyeolna. Conclusively, the selected Suwon 425 variety, which is coloured and flavour volatile one, showed relatively higher contents of anthocyanin, ferulic acid derivatives in the L
layer as well as L
layer when compared with Sanghaehangyeolna and even other varieties. This fact suggested that Suwon 425 could be a promising candidate for the development of health rice food.
Genitic Variability and Correlation of Quantitative Characters in Local Garlic Cultivars
Korean Journal of Plant Resources, volume 11, issue 3, 1998, Pages 264~271
This study was conducted to investigate morphological characteristics of Korean local garlic varieties and to define the genetic variability and the correlations amongthe characters associated with yield. The plant height, the leaf sheath diameter, the nubmer of leaves, and bulb weight were significantly increased in the garlic plants from heavier seed bulbs. The proportation of six clove bulbs was more than 60% in Seosan variety and this was not realted with the number of cloves in seed bulb. While more than 70% bulbs in Jeoksung and Danyang varieties cultivated in paddy field were composed of 6 or 7 cloves, majority of the bulbs of Euisung and Danyang varieties cultivated in upland were composed of bulbs with 7 cloves or more. The highest genotypic coefficient of variation (GCV) and phenotypic coefficient of variation (PCV) were observed in bulb weight. GCV and PCV also showed high value in leaf sheath diameter. Thus, there is a greater scope for selection of these characters. The small difference between PCV and GCV values in plant height indicates that the environmental influence would be limited in this character. High heritability was observed of plant height (56.76%) and bulb weight (45.95%). And the weight per bulb (34.24%) exhibited highest genitic advance followed by leaf sheath diameter (18.8%) and plant height (9.61%), and those would be the ideal characters for selelction.
A Study on the Functional Properties of Camellia(Camellia japonica L.) Seed Protein Isolate
Korean Journal of Plant Resources, volume 11, issue 3, 1998, Pages 272~278
This study was carried out to investigate the functional properties such as nitrogen solubility, emulsifying property , foaming capapcity , water and oil absorption of Camellia (Camellia japonica .) seed protein isolate in condition of distilled water and 0.5M NaCl solution at pH 2.0∼10.0. Nitrogen solubility of Camellia protein isolate in distilled water showed the minimum value at pH 4.0 and increased at pH lower or higher than the isoelectric point(pH 4.0). It was 90.0 %at pH 10.0 Nitrogen solubility of 0.5M NaCl solution showed a similar pattern with that of distrille dwater but was higher than that of distilled water except pH 2.0 and pH 10.0. Emulsifying activity of Camellia seed protein islate showed the minimum value at pH 4.0, but was higher at ether value of pH. Emulsifying stability of protein isolate was stable by heat treatment for 30min, at 80℃ and increased in 0.5M NaCl solution more than that of distille dwater. Foaming capacity of Camellia seed protein isolate in distill3ed water showed the minimum value near the isoelectric point, While it changed little at other values of pH. Foaming stability slowly decreased as, but didn't make a significant difference as time was delayed . Oil absorption was 1.4ml per a sample of 1g and water absorption was 0.9ml per a sample of 1g. The former was higher than the latter . The content of total amino acid of Camellia protein isolate was 43.67% and the major total amino acid of Camellia protein isolate was 43.67% and the major total amino acid was in the order of glutamic acid , arginine, aspartic acid, and leucine.
Essential Oil Conten and Composition of Aromatic Constituents in Some Medicinal Plant
Korean Journal of Plant Resources, volume 11, issue 3, 1998, Pages 279~282
This expriment was carried out to get basic information on composition and yield of aromatic constituents in leaves of four medicinal plants, Angelica tenuissima, Chrysanthemum zawadskii. ssp. latilobum, Artemisia iwayomogi and Artemisia capillaris. Volatile aromatic constituents, 28 compounds in Angelica tenuissima were identified and 19 compounds were indentified in Chrysanthemum zawadskii ssp. latilobum. Volatile aromatic constituents, 23 compounds in Artemisia iwayomogi and Artemisia capillaris were identified. Major volatile aromatic consitiuents analyzed by GC/MS in four plants were
-pinene, camphene, sabinene, cis-2-hexanol, and camphor etc. Content of essential oils in Angelica tenuissima, Chrysanthemum zawadskii ssp. latilobum, Artemisia iwayomogi and Artemisia capillaris were 0.014, 0.275, 0.785, and 0.452%, respectively. As a result, it was suggested that a medicinal plant, Artemisia iwayomogi, was worthy of using as a useful material of perfume.
Comparison on Morphology and saikosaponin Contents of Bupleurum falcatum Produced in Korea and China
Korean Journal of Plant Resources, volume 11, issue 3, 1998, Pages 283~289
To determine the differences among cultivated , non-cultivated and imported bupleurum falcatum, contents and compositions of fatty acids and saikosaponins which are known as a major biologically acitive compounds in Bupleurum falcatum were meausred with GC and HPLC. Color of grinded powder of Bupleuri radix determined by colorimeter showed that the imported one has the highest white and yellow coloer Among the Bupleuri radix cultivated in China, Hong-siho(red-Bupleurum) produced in Yungil Province contained the highest red color. Cultivated Korean Bupleurum radix contained higher saikosaponi a, c, and than the imported ones which were cultivated in Yungil, Ankuk , and Gillium Province in China. Levels of saikosaponin c are 3 times higher in cultivated Korean Bupleuria radix compared the with imported ones. Furthermore, Bupleurum falcatum cultivated in Korea contained higher amount of palmitic and linoleic acids than those of improted and non-cultivated ones. Particularly they contain two to six times higher linoleic acid.
Presowing Treatment Effects of GA3 and Light Quality on Seedling Emergence and Growth of Tobacco
Korean Journal of Plant Resources, volume 11, issue 3, 1998, Pages 290~295
Presowing treatements to seed are reasonable for elevating the seedling production efficiency. This experiment was carried out to determine the effects of
[0 (water) : 0.01 mM] and light qulaity (red : white) simultaneously treated before sowing on seedling emergence and growth of tobacco (Nicotiana tabacum L.) cv NC 82 and Burley 21. Red or white light was illuminated 12 hours a day while seeds of the cultivars were imbibed with either water or
0.01 mM for 3 days. Seedling emergence was measured up to 20 days after sowing but morphological characters and dry weights were done 40 days. The seedling emergence rate of cv NC 82 was more affected by light quality and
pretreatments than that of cv Burley 21. Light quality more influenced the rate than
while red light or water imbibition enhanced the rates of the two cultivars compared to the other treatement. Although mean plant height and leaf number per seedling were nearly equal between the treatements, red light declined leaf area per seedling of cv Burley 21 of which seeds were imbibed in water but white light decreased the areas of both cultiars of which seeds were soaked in
solution. Shoot dry weight was greater in cv NC 82 but less in cv Burley 21 pretreated with red light, and root dry weight showed the reverse result in white light, meaning that presowing light and
treatments could be changed the seedling development and growth of tobacco.
Effect of Tree Species, Inoculation Amount and Inoculation Methods on Mycelium Growth and Sclerotia Formatino of Poria cocos Wolf
Korean Journal of Plant Resources, volume 11, issue 3, 1998, Pages 296~300
When medicinal mushroom, Poria cocos, is cultured , inoculation method of spawn is cross slice inoculation of which the both sides of pine tree were peeled and spawn of P.cocos was inoculated. However, this method required lots of inoculation amount. This study was carried out to improve the culturing method of P. cocos. A good growth of P.cocos was observed in MCM(mushroom complete medium), showing proper mycelia growth and density. In inoculation amount, conventional method(cross slice inoculation) requires 20 bottles of spawn. In contrast, short log method required 8 bottles of spawn and drilling inoculation method 2~3 bottles, which could save by 60% and 85-90% respectively. In the selectrion of tree species, pine and larch had better condition for spawn culture and sclerotia formation condition.In terms of yield , pine was 33.7kg/3.3
. In the yield of pine, conventional method was 23.4kg/3.3
, drilling inoculation 29.4kg/3.3
, short log inoculation 31.7kg/3.3
, therefore drilling inoculation could increase by 25% and short log inoculation 35%, In addition, management cost was also saved.
Effectof natural type ABA foliar application on growth, yield of Codonopsis lancelata
Korean Journal of Plant Resources, volume 11, issue 3, 1998, Pages 301~306
In order to improve cultivation technuque of C. lanceolata, natural ABA was treated with foliar application periodically during differenctitation of node. The higher is concentration and the earier its foliar application was, the shoter plant height was. Especially, when
of ABA was treated at differentiated stage of 3rd node, plant height was inhibited to 60% of control. But leaf length, leaf width, and number of branches have no significant differnence in comparison wiht control. The fresh weight of subterranean part was similar to control independent of treat-time in the case of
. When 1,5 and
of ABA were treated at initial differentiated node stage, plant height inhibited to 20~30% of control, but subterranean part was similar to control. All treatement showed slight antitumor activity by the P388 cytotoxic screening test.
Study on Matter Production and Phothsynthetic Characteristics in Wild Vegetable(Chwinamul)
Korean Journal of Plant Resources, volume 11, issue 3, 1998, Pages 307~314
The response of water stree under high and low temperatures, was shown differently according to the longer the suspension period of water supply. Leaf photosynthetic rate(LPS), leaf water potential(WP), relative leaf water content and relative soil water content were lower. At the higher temperatures, the percentate of reduction in LPS and WP was greater than at low temperatures. It is suggested that evaporation rate should be higher in the high temperature than the lower temperature. Also leaf water potential was lower at high temperature than at low temperature. After the 9 th day of treatment , LSP was remarkably reduced at high temperature, but the reduction of LPS was not significant at low temperature. Solidago virga-aurea var. asiatic that maintained LPS of 3rd day after treatment was more strong than other varieties at low temperatures. The silting and curling of leaves were observed symptoms of stress on the 9th day at the both temperatures. The leaves of aster scaber and Ligularia fischeri turned red on the 9th day after treatment at low temperature.
Studyon the Cultivation Methods of Transplanting the Turf Seedling I. The Effect of Turf Growth with Different Seedling Rates on the Seedling Tray
Korean Journal of Plant Resources, volume 11, issue 3, 1998, Pages 315~318
This study was carried out to investigate the effect of seedling growth with different seedling rate for machine transplanting with turf. Chosun Zoysia was sown on May 17 with three levels seedling rates. The plant charactersitics were greater in 500g/box plots than the other seedling rates on the seedling box. It ws shown that the 30-40day old seedlings of 1.000 and 2,000g/box seedling plots appeared to be proper methods for Sprigging as the high seedling density. The 70 day old seedling plant with 500g/box were shown to be propoer methods for Sprigging. The seedling periods need to be 60 days for 500g/box plots and 40 days for 1,000 and 2,000g/box plots as forming the mats.
Development Changes of the Secondary Xylem Elements in Aristolochia manshuriensis Komarov
Korean Journal of Plant Resources, volume 11, issue 3, 1998, Pages 319~325
The developmental changes occuring in the secondary xylem of Aristolochia manshuriensis Komarov have been studied in different ages of vine stems. A. manshuriensis possesses typical storeyed cambium comprising both vertically elongated fusiform initials and almost isodiametric ray cell initials. Stems of A. manshuriensis have wide rays that make the secondary xylem appear dissected as other vine types. The length of vessel member and fiber remained relatively constant throughout the secondary growth. However, vessel diameter increases with the increasing age of stem till the cell reaches their maximum limit and later more or less stabilize in diameter while number of vessel per
is vice versa. Width and relative proportion of ray to axial elements gradually increased with the increasing age of stem and later remained relatively constant.
Comparative Study on the Structure of Vascular Cambium in Some Salicaceae
Korean Journal of Plant Resources, volume 11, issue 3, 1998, Pages 326~334
Vascular cambium in 16 species of Salicaceae is nonstoried in all of them and is made up of fusiform and ray initials. The growth of cambial girth occurred by pseudotransverse division of fusiform initials and subsequent apical intrusive growth of daughter initials. The measurements of fusiform initials in tangerntial sections have revealed that the average length varies from 252.2-437.1
in investigated species, with the maximum being in Populus euramericana and the minimum in Salix purprea var. Multinervis. The length of fusiform initials depends on the length of the tapering end wall , therefore, the longer the length of the tapering end wall, therefore, the longer the length of the taperding end wall, the longer the length of fusiform initials. Ray initials have their own size, magnitude, and frequency of occrrence in each species. The relative proportion of ray initials fall about 15.0-24.5% in Salicaceae. Shrubby species of Salix have a lower ratio of ray initials than the species which possess wider trunks. New ray initials are originated from cut off the side or the end of fusiform initials and central partition of a fusiform initials.
Pericarp Anatomy of Fagopyrum (Polygonaceae)
Korean Journal of Plant Resources, volume 11, issue 3, 1998, Pages 335~344
Percicarp anatomy of Fagophrum was examined on the basis of 12 species and two subspecies to contribute to a better understanding of specific phylogenetic relationship within genus. Examined species have a similar mature pericarp structure, but differences among the species are found with respect to whether or not sclerotic cells are present, and what kind of is the sclerotic cell shape in theexocarp. By the comparisons with pericarp anatomical structure, they are classified into three groups. First clade is composed of F. esculentum , F. esculentum ssp. ancestralis and F. homotropicum ; second clade is consisted of F. tataricum, F. tataricum ssp. potanini and Fl cymosum ; third clade is composed of f. callianthum,F. capillatum, F. gracilipes, F. leptopodum, F.lineare, F. pleioramosum, F.statice and F.urophyllum. The phylogey based on pericarp characters was considerably consistent with ones proposed by previous authors. It also suggested that pericarp characters are useful informatino for deduceing phylogenetic phylogenetic realtionship within geneus Fagopyrum. On the other hand, morphological character evolution indicated that there are tow synapomorphies in genus. There,it was suggested that these species having selfing and homostylous characters are evolved form heterostylous and ourcrossing species.
Population Structure, and Emergence and Growth Dynamics of Seedling, and Spatial Distribution of Dendropanax morbifera Lev.(Araliaceae)
Korean Journal of Plant Resources, volume 11, issue 3, 1998, Pages 345~352
A Korean endemic and evergreen small tree ' Dendropanax morbifera
.(Araliaceae)' is a component of evergreen forest and mainly idstributein sourthern region and islands in Korea. A local population of D. morbifera which is located between evergreen and deciduous forest within 50m x 50m quadrate was investigated to ascertain the change of population structure, emergence and growth dynamics of seedlings and saplings, and pattern of spatial distribution by the temproal and spatial expansion of population . The result of analysis of population structure by Importnace Value(IV), evergreen forest showed a high species diversity of evergreen tree species such as Cinnamomum japonicum, Machilus japonica, Neolitsea serica, Daphniphyllum macropodum, Ligustrum japonicum, and etc, in middle and under story than in upper story where Camelia japonica and Quercus acuta were dominant. And in conterminous deciduous fores, the major component of evergreen forest in this region, Camellia japonica, Quercus acuta, evergreen tree of Lauraceae and etc. were abundant in only under story. IV of D. morbifera differed from among three story. In comparative analysis of emergence and growth dynamics of D. morbifera seedlings and saplings between evergreen and deciduous forest, emergece and density of seedlings were significantly greater in evergreen than in deciduous forest, and growth of height and basal diameter of seedlings and saplings were slightly larger in evergreen than in deciduous forest. The spatial distribution patterns by Moristia's index mapping of indivuduals using a lattice method of XY axis within this population showed that seedlings(age up to 2 years) and saplings (age>2 years and height<1m) both evergreen and deciduous forest were more or less aggregated apart from mature trees, and thougth intermediate trees(height>1m and dbh<10cm) had a aggregated distribution pattern, mature trees(dbh>10cm were uniform. In conclusion , the expansion of D. morbfera population from evergreen to deciduous forest accompanied with a mumber of evergreen woody species, and also, emergence and recruitment, and growth of seedlings were greatly influenced moisture and canopy by around community structure.
Effect of Growth Regulators, Genotypes and Cutting Position on Rooting and Root Growth of Chrysanthemum zawadskii H.
Korean Journal of Plant Resources, volume 11, issue 3, 1998, Pages 353~357
This study was conducted to determine the effect of growth regulators, genotype, and cutting position on the rooting and root growth from cutting of Chrysanthemum zawadskii H.. Rooting rate of Keungugeolcho in the treatement of IBA 500 and 1000 ppm was the better than those of other treatments of IAA, NAA and Rooton. Rooting rate differed depending on the genotype. Hangryobonggugeolcho was better than Keungucheolcho in rooting rate. The treatment of rooton remarkably induced many roots from the cuttings of eight accessions of Chrysanthemum zawadskii H.. Also, rooting rate and number of root differed depending on cutting position. When cuttings including shoot tip were cultured on tray containing bed soil, rooting rate and number of root induced from cuttings with shoot tip was higher than when cuttings without shoot tip and with lateral axillary bud were cultured.
Preparation of High-Fiber Bread with Camellia (Camellia Japonica L.) Seed Flour
Korean Journal of Plant Resources, volume 11, issue 3, 1998, Pages 358~362
This study was carried out to examine the effect on the contents of dietary fiber, mechanical properties, and sensory quality of bread contained with 10% of high-fiber Camellia (Camellia japonica L.) seed flour. Bread added by dietary fiber was the contents of moisture, protein and ash higher than control bread, while the contents of lipid lower than that of control bread. The high-fiber with Camellia seed flour contained 8.6% soluble dietary fiber, 43.7% insoluble dietary fiber, and 52.3% total dietary fiber. The ratio of insoluble dietary fiber/soluble dietary fiber in the high-fiber with Camelia seed flour was 5 times. Bread with the addition of dietary fiber contained 6.9% total dietary fiber. With the addition of dietary fiber, water absorption , mixing time loaf weight, and hardness increased, but the loaf volume decreased . The sensory quality on bread added by dietary fiber was somewhat low in color, appearance, crumb texture, mouthfeel, flavor and overall preference was higher than that of control bread.
