Excellent Strains Selection from Wild Cordyceps spp.(I)
Korean Journal of Plant Resources, volume 13, issue 3, 2000, Pages 155~161
Many Cordyceps rpp were collected for excellent strains selection at Mts. Moak, Younsuk and Daea-ree herbarium near Wanju-kun from mid May to October,1999. They were identified as the resulting 2 genera and 5 species, 10 strains were got through 5 species culture. Among them 4 species used for induction of artifitial fruiting body and 6 strains of them were selected to excellent strains: Cordyceps militaris (99-0007), Isaria japonica (99-0001, 99-0002, 99-0003), Cordyceps soborifera (99-0008), Cordyceps kanzashiana(99-0009).
Effects of Urban Greenspace on Microclimate Amelioration,
Sequestration and Eire Obstruction
Korean Journal of Plant Resources, volume 13, issue 3, 2000, Pages 162~170
This study quantified the effects of urban greenspace on microclimate amelioration and atmospheric
reduction for several residential districts selected in Korea and Japan. The study also explored fire obstruction by urban trees to develop systematic planting guidelines. Transpiration by a Zelkova serrata tree (diameter at breast height: 15 cm) in a day of August equaled cooling effect of about 3 air conditioners running for 12 hours. Average air temperature for the growing season was 0.5
cooler, respectively, in districts with 12% and 22% cover of woody plants than in a district with no vegetation. Annual
production by woody plants were 3 times greater in a district which was 2 times higher in their cover. Woody plants played, in a district with their 22% cover, an important role through offsetting total
emission from the district by about 3% annually, and through producing 10% of annual
requirement by all residents within the district. Appropriate planning strategies of residential greenspace, including species selection, planting layout, greenspace enlargement, and maintenance were suggested to improve microclimate amelioration, air purification, and fire obstruction.
Protective Effects of Some Plant Extracts on Lipids Contents of Rats Treated with Carbon Tetrachloride
Korean Journal of Plant Resources, volume 13, issue 3, 2000, Pages 171~178
This study was performed to investigate the possible effects of some plants protecting intact rat liver damaged by
. The extract of mugwort (Artemsiae capillaris), soybean sprout and pine leaf (Pinus strobus) inhibited markedly the in vitro activities of rat liver fatty acid synthase, whereas those of shiitake (Lentinus ododes), Houttuynia cortata, Acanthopanacis cortex and buckwheat leaves had less effects. Treatment with the water extract of pine leaf and soybean sprout caused a marked decrease in the
-induced toxicity in rat liver, judged from their effects on the levels of glutamic oxaloacetic transaminase (GOT) and glutamate pyruvic transaminase(GPT) in the serum. The extract of mugwort and soybean sprout reduced markedly the content of liver microsomal peroxides induced by
treatment and serum TBA values, respectively. The extract of soybean sprout decreased efficiently the content of liver triglyceride elevated by
treatment. Nevertheless, the extracts did not exert the supression of hepaticmegaly induced by
. The results suggest that soybean sprout and pine leaf may be potential sources improved the biochemical parameters like as peroxidation value or serum GOT and GPT, although these extracts had minimal effects in the increase of liver size induced by carbon tetrachloride.
Taxonomic study on the achene morphology of Korean Aster L. and its allied taxa
Korean Journal of Plant Resources, volume 13, issue 3, 2000, Pages 179~187
The achene morphology about 16 taxa of Korean Aster L. sensu lato were investigated to estimate its taxonomic values. The achene shapes were divided into four types; oblanceolate-oblong, obovate, oblong and obovate-oblong. The trichome shape on achene six types; uniseriate-conical, filiform, cylindrical, capitate type, long stalk capitate and globular. Their distributional features on upper part of achene four types; absent, sparse distribution of conical trichome, dense distribution of conical trichome and mixed distribution of conical and capitate trichome. The achene shapes and trichome characteristics were regarded to be a good characters in delimiting taxa because these did not differ among individuals in same taxa, but differ among the taxa. If Korean Aster L. sensu late were divided into Kalimeris, Heteropappus, Aster, Cymnaster, the capitate forms and mixed distribution of conical and capitate trichome were recognized as the good characters in delimting above section such as genus Kalimeris and Heteropappus, section Pseudocalimeris of Aster L. sensu stricto.

Gujeol. Most of the habitat faced toward the northeast aspect and the gradient was ranged from 25 to 33 degrees. The light intensity of Dicentra community was 14,000lux on the average, and it was tendency to decrease by foliation of other woody plants. The appearance number of Dicentra per quadrat was 30 individuals on the average, and total appearance species in all quadrat surveyed was 52 taxa. Among them, Quercus mongolica, Lindera obtusiloba, Corylus heterophylla, Cornus controversa, woody plants, Corydalis speciosa, Pseudostellaria heterophylla, Artemisia keiskeana, Dryopteris crassirhizoma, Arisaema amurense var. serratum, Carex siroumensis, and Chloranthus japonicus, herbaceous plants, were showed as dominant species. Soil acidity in the habitat was 5.15 to 5.96, and average content of soil moisture was 32.6%. The contents of average organic matter,
, K, Ca, and Mg were 1.99%, 14mg/kg, 0.55me/100g, 15.2me/100g, and 3.3me/100g, respectively. Electron conductivity was ranged from 0.50 to 0.76dS/m. Also, the average air temperature of May and June was 14.2
Effect of split achene pericarp, Giberellin, and germination temperature on the germination of Rosa davurica Pall
Korean Journal of Plant Resources, volume 13, issue 3, 2000, Pages 195~201
This study was conducted to investigate the suitable conditions for seed germination of Rosa davurica PALL. In the characteristics of the fruit and seed of Rosa davurica, fruit length and width was 1.3cm and 0.9cm , respectively, and seed number was eighty-nine. Artificial and low temperature storage at 4
increased the rate of split achene pericarp until 46.6% and storage at 15
incubator decreased the rate of split achene pericarp (10.5%). The rate of seed germination of split achene pericarp in control at 15
was 90% and of non-split achene in GA
100ppm at 15
was 36.8%. Average germination day of split achene pericarp seeds in GA
150ppm at 2
was 4.2 days and non-split achene pericarp in GA
100ppm at 2
was 7.3 days. Seed germination was not different between various concentrations of GA
treatments in split achene pericarp seeds but the rate of germination was more reduced in high concentration of 200ppm. Only the treatments of GA
was increased germination rate at 4
and immature seed of Rosa davurica.
Effect of Prechilling and Alternating Temperature on Seed Germination of Native Plants
Korean Journal of Plant Resources, volume 13, issue 3, 2000, Pages 202~207
This study was conducted to investigate the characteristics of seed germination pattern by the prechilling and alternating temperature treatments to 16 species of native plant. The seed length, width and thickness ranged from 1.1 to 8.9 mm, from 0.7 to 7.5 mm and from 0.4 to 1.7 mm, respectively. In addition, the 1,000 grain weight of native plants ranged from 0.1 to 8.8g. Germination rate of Melandryum firmum R. and Saussurea pulchella F. with light condition, Capsella bursa-pastoris L. and Leonurus sibiricus L. with dark conditionin of non-treatment were the highest 69, 81,16 and 36%, respectively. Germination rate of Aster scaber T., Cirsium setidens N., Ligularia fischeri T., Plantago asiatica L., and Saussurea sp. of 5
prechilling for 30 days were the highest 84, 29, 29, 57, 78 and 95% with light condition respectively, 30% but Cirsium nipponicum M. only with dark condition. Germination rate of Aralia elata S., Aster koraiensis N. and Synurus deltoides N. of alternating temperature with 8 hours at 3
and 16 hours at 15
were the highest 2 and 57% with light condition and 52% with dark condition.
The effect of various heat covering materials on the sprouting and occurrence of disease, insects during wintering of grape young tree (Shigyoku)
Korean Journal of Plant Resources, volume 13, issue 3, 2000, Pages 208~212
The effect of heat covering materials during cultivation of Shigyoku grape was examined on the effect of protection from freezing damage, labor reduction, and disease resistance during the wintering. This experimentwas accomplished using different combination of heat covering materials from the end of Nov as follows: straw and heat conservation cover B, kilding, color fabric A, and white needle punching fabric. Capacity of heat conservation was the least form white needle punching fabric, and the differences of other materials was slight. Early sprouting occurred by the treatment with heat conservation cover B, and the rate of sprouting was about 70.7% after 9 days of sprouting, showing 2.3-12.5% increase. Growth effect was not differ between heat conservation materials. Disease and insects occurred by the in dice 3.0-3.2 of crown gall from the heat conservation cover B treatment. Other damages were not observed or very little from other treatments. Demand of labor during steps of these treatments was more observed by 6% for kilding than heat conservation cover B, and those of color fabric A and white needle punching fabric were reduced by 6 and 15%, respectively.
Major Morphological Characteristics of Safflower(Carthamus tinctorius L.) Accessions
Korean Journal of Plant Resources, volume 13, issue 3, 2000, Pages 213~218
Morphological characteristics of 16 collected safflower (Carthamus tinctorius L.)accessions were studied at Gyongbuk A.T.A. Uisong Medicinal Plant Experiment Station in 1998. As for plant height, 5 lines were tall(more than 131cm), which were mainly foreign safflower. Middle and small were 5 and 6 accessions, respectively. Number of branch per plant was 11∼13 in 2 accessions of domestic safflowers while foreign safflowers have more than 50 branches per plant. Leaf shapes were oblong(3 lines), lanceolate(10 lines) and broadly linear(3 lines). There were three types of leaf margin shape which were repand(7 lines), serrate(4 lines) and parted serrate(5 lines). Flower color was white(1 line), yellow(13 lines) and red orange(2 lines). As for flower head shape, 14 lines were conical and 2 lines were flattened. There were thorns on bract of flower head in 11 lines but in 5 lines there were not. Domestic safflower lines had seeds of conical shape. Contrastively, seed shapes of foreign saffower lines were oval.

Korean Journal of Plant Resources, volume 13, issue 3, 2000, Pages 219~226
The experiments were conducted to investigate the characteristics of the seed germination and the bulb dormancy in Korean-native Allium victorialis L. by the physicochemical treatments. The characteristics of two Allium victorialis seeds was similar in shape, color and threshing but different in other characters. Weight of 1,000 grains in Ullrung-native was 14.8g corresponding to 2.1 times as compared with Odae-native. Seeding immediatly after seed collection of Ullrung-native only germinated and chemicals didn't affect in germination improvement. The germination rate, average days to germination and coefficient of germination of Ullrung-native was 86%, 42 days and 2.05 at the dark condition of control, respectively. The germination rate, average days to germination and coefficient of germination of Odae-native was 70%, 47 days and 1.5 at the dark condition of control and 82%, 47 days, 1.75 at the light condition after 5
prechilling for 30 days, respectively. The bedding days to reduce the physiological dormancy in the bulb of Odae-native assumed to be appropriate up to 45 days after the first prechilling.
Site Characteristics, and Vegetation Structure, and Dynamics of Forest Communities growing Kalopanax septemlobus (Thunb.ex Murray) Koidz. in Gangwon-do
Korean Journal of Plant Resources, volume 13, issue 3, 2000, Pages 227~242
Site characteristics, vegetation structure and dynamics of Kalopanax septemlobus forests in Mt. Heungjeong, Mt. Balwang and Mt. Gariwang were studied to provide the information need for national resources conservation and restoration of K. septemlobus forest in Gangwon-do of Korea. The K. septemlobus forests were distributed at 780m to 1,300m in altitude, steep slope, ridges-slope areas with facing northeast to northwest in good nutrition area. The annual diameter growth of those trees ranged 1.60mm to 2.41mm. Forty-three plots(20
20m) were set up at three natural population of Kalopanax septemlobus forest and TWINSPAN method was used for vegetation structure analysis. The result of TWINSPAN ordination show that geographical features played a role in determining community types in the study areas. Community type of the study areas classified into three groups by TWINSPAN; K. septemlobus-Quercux mongolica- Acer mono community(Mt. Balwang), K. septemlobus-Q. mongolica- Tilia amurensis community(Mt. Heungjeong), K. septemlobus-Betula costata-Q. mongolica community(Mt. Gariwang). In most of the K. septemlobus forests, major woody species appeared predominantly were Q. mongolica, T. amurensis, Acer pseudo-sieboldianum, Lindera obtusiloba, A. mono, Magnolia sieboldii, Ulmus davidiana var. japonica. And also, Those species were surveyed in all the areas. Species diversity(H') of investigated areas ranged 0.3124~0.13992 and this value relatively higher than that of other forests with similar site. The range of similarity indices between surveyed areas was 64.1~64.54%. The distribution pattern of Morista's index show that Kalopanax septemlobus distributed randomly in tree and concentrated a few sample plots in subtree layer and shurb layer. K. septemlobus occupied 37.1~58.8% of tree layer story, 8.4~17.6% of subtree layer, 0~0.38% of shurb layer each surveyed area. The association analysis showed that Kalopanax septemlobus positively associated with Betula ermani, Deutzia glabrata, Carpinus cordata, Fraxinus mandshurica and negatively associated with Symplocos chinensis var. pilosa, Styrax obassia, Acer mono, Euonymus macroptera, Ulmus davidiana var. japonica. According to the diameter distribution of Kalopanax septemlobus community, the community of Mt. Gariwang will gradually decline and replaced by Quercus community. The communities of Mt. Heungjeong and Mt. Balwang has its seedlings and saplings, so it may be sustained.
Effect of Weed Control and Lodging Reduction for Increase the Grain Yield of Buckwheat
Korean Journal of Plant Resources, volume 13, issue 3, 2000, Pages 243~248
This study was conducted to evaluate the effects of weed control and lodging reduction in the cultivation of buckwheat. The effect of weed control was significant. In the herbicide plot, nevertheless, grain yield and plant height were more decreased than habitual and vinyl mulching plots. Therefore, the application of herbicide was considered unnecessary in buckwheat cultivation having short growth period. In the habitual plot, dominant weed species are Digitaria sanguinalis, Erigeron annuus, E. canadensis, Setaria viridis, and Stellaria alsine var. undulata. On the effect of plant dwarf agent, C.C.C. and TIBA, plant height became shorter than habitual plot but the grain yield decreased. The latter tip pinching time, the less in grain yield which indicate tip pinching is ineffective in grain yield and lodging reduction. Among the wild species and cultivars of Fagopyrum, F. urophyllum was differentiated into xylem and phloem tissues indicating woody plant. Stem hardness of this species was the hardest as 625,110,000 dyne/cm
which is at least 3.5 times harder than F. esculentum cv. Suwon #12. Therefore, it needs that the woody habitat gene of F. urophyllum is transfered into other cultivars in buckwheat breeding strategy.
Farm survey on the application of solar energy system to the controlled culture
Korean Journal of Plant Resources, volume 13, issue 3, 2000, Pages 249~254
Heating supply system using solar energy-collecting plate was examined for 20 farmers. Some problems, resolution, future energy system, and basic information were discussed, Installation cost was approximately 18 million won/20a. Main crops cultured were tomato(30%) and floricultural crop(40%). Minor crops cultured were grape, red pepper, cucumber, lettuce, and strawberry. Information was mostly obtained from agricultural service agents. 75% of farm house hold reported that energy reduction effect was below 20%, showing some different result compared with over 20% that was totalized from agricultural service agents. Cost of installation was excessive in considering energy reduction effect. Another problem was insufficient technical proficiency of solar energy company.
Insect Pest Control of Aphides for Alisma plantago Cultivated after Early Maturing Rice Cropping
Korean Journal of Plant Resources, volume 13, issue 3, 2000, Pages 255~259
This study was conducted to evaluate the effect of pesticides on insect pest control of Aphides, growth characteristies and dry root yield from the cultivated after early maturing rice cropping. All pesticides treated had no effect on the growth period, flowering rate of Alisma plantago. The major pesticides were Methomyl-Lf, 24.1%., Imidacloprid-Wp, 10%., Car-bosulfan-Wp, 20%, and Methomyl-Wp,45%. Dry yield of root were increased largely with Imidacloprid-Wp, 10%(10g/20 ι), pesticide than the other pesticides and no control. All pesticides were had no injury with recommended concentration. On the other hand all pesticides were slightly harmful in the double dosage level for the Alisma plantago.
