The Selection Alisma plantago Varieties Suitable for the Southern Part of Korea
Korean Journal of Plant Resources, volume 14, issue 3, 2001, Pages 183~187
In order to obtain basic information for breeding varieties of Alisma plantago which is suitable for the southern part of Korea, nine local varieties were grown and yield components of plant were observed from Jun. 1999 to Dec. 1999 at farm field of Chonnam Sunchon Korea. Alisma plantago cv. Sunwol showed higher dry root yield than the other varieties used in the experiment. It showed relatively higher length of plant height and lower numbers of floral axis. Therefore, it was concluded that Sunwol was the most suitable variety with high yield and low floral axis at the southern part of Korea. The heritabilities of all observed characters were estimated to be large. Dry root yield was shown highly significant positive correlations with plant height and numbers of leaves. Dry root yield, plant height and numbers of leaves were shown negative correlation with number of floral axis and nursery leaves.
Anatomical study of Atractylodes japonica Koidz. ex Kitam. and A. macrocephaza Koidz.
Korean Journal of Plant Resources, volume 14, issue 3, 2001, Pages 188~195
The anatomical characteristics of rhizome, lateral root, stem, leaf, petiole, ovary and leaf epidermis about Atractylodes japonica Koidz. ex Kitam. and A. macrocephala Koidz. were investigated to estimate these taxonomic values. The cross sections of stem and ovary were very similar to two species, therefore these characters were not useful for delimitation of two species, but the size and distribution numbers per 100
of oil cavites in rhizome, the shape of leaf and petiole in cross section, the size of leaf epidermal cell and distribution numbers per 100
of stomata were differ from two species, therefore these were thought to be useful characters for delimitation of two species.
Cultivation of Oyster Mushroom Using Non Sterilized Media
Korean Journal of Plant Resources, volume 14, issue 3, 2001, Pages 196~205
The results of examining cultivation of tlyster mushroom using NSM(Non Sterilized Media) for determining the condition of artificially culturing oyster mushroom(Pleurotus ostreatus) are as follows. Mycelial growth an[1 density of oyster mushroom. were the highest in the medium of waste cotton(spinning) : corn cob(80 : 20, V/V) followed by the order of rice bran, beet pulp. Expecially, mycelial growth and density of oyster mushroom is the lowest at the mixture rate of 80% waste cotton(spinning) : 10% beet pulp. Mycelial growth and density of oyster mushroom. were the highest in the medium of cotton seed hull and beet pulp mixture followed by the order of rice bran, corn cob. Expecially, mycelial growth and density of oyster mushroom is the lowest at the mixture rate of 80% cotton seed hull : above 20% rice bran. Mycelial growth and density of oyster mushroom were the highest in the medium rate of 70% waste cotton(spinning), 10% corn cob and 10% beet pulp(V/V). Mycelial growth and density of oyster mushroom were the highest in the medium rate of 70% cotton seed hull , 10% corn cob and 10% beet pulp(V/V). Optimal concentration of NSM for the mycelial growth and density of oyster mushroom were shown to be 500 times concentration. Optimal water contents for the mycelial growth and density of NSM was 70%.
Screening and Utilization of Antifungal Plant against Ginseng Anthracnose (Colletotrichum gloeosporioides)
Korean Journal of Plant Resources, volume 14, issue 3, 2001, Pages 206~212
Crude extracts from 20 species of plants 16 families were evaluated for their antifungal activities against Colletotrichum gloeosporioides, and three plant extracts of them were applied to Ginseng in order to investigate the usefulness for Ginseng anthracnose control. Among the crude extracts from 20 species being tested, it of A. cepa, R. undulatum and C. japonica showed considerably antifungal activity against mycelial growth and conidial germination of C. gloeosporioides.. Ginseng anthranose was controlled at 2% concentration of A. cepa and R. undulatum and 1% C. japonica extract, but control value of three plant extracts was inferior to Mancozeb WP. Phytotoxic symptoms were observed in the leaves of ginseng with exogenous foliage application of 10% concentration of three plant extracts and 2% concentration C. japonica extract but not observed at 1% concentration.
Bottle Cultivation of Pleurotus ostreatus, Agrocybe aegerita and Ganoderma lucidum by using Rice hull media
Korean Journal of Plant Resources, volume 14, issue 3, 2001, Pages 213~219
Rice hull was used as an additive in order to determine the its effect on increse of mushroom growth and yield in Chungnam Provincial techinical institution. In the treatment of 80% rice hull in small Neutaribeosut, mycelial growth duration was shown to be shorter about 11 days and yield increased about 7oie than those of conventional culture. In the case of Chongpung Neutaribeosut bottle culture, mycelial growth duration was shorter about 2 to 3 days in additive of 30 to 80% rice hull compared to conventional, but yield was similar to that of conventional. In the treatment of 30% rice hull in Agrocybe aegerita bottle culture, mycelial growth and yield increased 6 days and 6% than those of convrntional, respectively. In the treatment of 30% to 40% rice hull in Ganoderma lucidum bottle culture, mycelial grow durations were similar 45 days and 38 g/bottle.
Evaluation of the antioxidant potential and enzyme activities in species of Rhus
Korean Journal of Plant Resources, volume 14, issue 3, 2001, Pages 220~228
Comparison of the antioxidant potential and enzyme activities of the extracts of Rhus showed considerable differences. The antioxidative activities of Rhus javanica were the highest of three species tried (7
). The highest activities showed in fraction No.3 of 12 fractions by Sephadex LH-20 column chromatography and the antioxidative activity showed, in purified extract of each stem,1.5
(in Rhus verniciflua), 1.9
(in Rhus javanica) and 2.3
(in Rhus tricocarpa) respectively. These were identificated as phenolic compounds which are well known antioxidant compounds such as 2-propenoic acid (Caffeic acid), Benzoic acid (Gallic acid), 7-hydroxy- 6methoxy-2H-1-Benzopyran-2-one (Scopoletin). POD activities of stem were higher than leaf. Especially, POD activity in stem of Rhus javanica was 193 times higher than leaf. Rhus tricocarpa, however, showed very low POD activity. SOD activities of stem were higher than that of leaf in Rhus javanica and Rhus verniciflua but in Rhus tricocarpa, the activity of leaf was 25 times higher than that of stem.
Study on Utilization of Cermets as Seed Corms in Tnro, Colocasia antiquorum var. esculenta
. 1 . The Effect of Cermet Weight on Growth and Yield in Taro
Korean Journal of Plant Resources, volume 14, issue 3, 2001, Pages 229~234
In order to investigate the possibility of utilizing small cermet as a seed corm in taro, the small cermets classified by the weight were planted on April 30,2000. The effect of weight of small cermets(5,10, If,20,25, and 30g) and corms on the growth, yield, and quality of taro was compared to those raised from cermets. The larger the size of cormel was, the more number of leaves developed, and the higher the yield was. Also the growth of small cormel was normal, so we forecast that it is possible to use small cermet as seed corm in mass production of taro.
A Simple and ]Reliable Method for PCR-Based Analyses in Plant Species Containing High Amounts of Polyphenols
Korean Journal of Plant Resources, volume 14, issue 3, 2001, Pages 235~240
Polymerase chain reaction (PCR) is used in a wide array of researches in plant molecular genetics and breeding. However, considerable time and cost are still required for the preparation of DNA suitable for reliable PCR results, especially in plant species containing high amounts of polyphenols. To reduce time and effort for PCR-based analysis, a simplified but reliable method was developed by a combinational employment of a simple and fast DNA extraction procedure and BLOTTO (Bovine Lacto Transfer Technique Optimizer) in reaction mixture. Genomic DNAs prepared by one-step extraction method from recalcitrant plant species such as Rubus coreanus, apple, grape and lettuce were successfully amplified by random primers in the reaction mixture containing 2 to 4% BLOTTO. Successful amplification of
-TMT transgene in lettuce transformants by the specific primers was also achieved in the same condition, making rapid screening of positive transformants possible. Our results suggest that use of a simple DNA extraction procedure and incorporation of BLOTTO in reaction mixture in combination can reduce time and effort required for the analyses of a large number of germplasms and transformants by PCR-based techniques.
Effects of Cutting Media in Root Cuttings of Lacquer Tree (Rhus verniciflua Stokes)
Korean Journal of Plant Resources, volume 14, issue 3, 2001, Pages 241~246
Effects of cutting media on shooting and seedling characteristics were investigated to determine productivity of seedling by root cuttings of lacquer tree. Shoots developed at 3 weeks after cut planting on PV (peat moss : Vermiculite : 1 : 1), PVS (peat moss : Vermiculite : Sand : 1 : 1 : 2) and PVSC (peat moss : Vermiculite : Sand : Clay loam : 1 : 1 : 2 : 2) media, and shooting rate was the highest in PVSC medium at 10 weeks after cut planting among the treatments. Shooting numbers per scion on PH and PVC media were 2.2 but those on HSC medium was 1.3, which was not significantly different among media. PVSC medium was suitable to use the root cuttings of lacquer tree as it meets the qualifications requirements. Seedlings on PVSC medium were excellent to transplant in field as tree height, branch number, leaf number, stem diameter and leaf area were good.

Korean Journal of Plant Resources, volume 14, issue 3, 2001, Pages 247~250
Two naturalized taxa in Jeju such as Tradescantia flumiensis Vell., and Lotus tenuis Wald. et Kit. ex WiIId. are newly recorded. Short descriptions and illustrations for these taxa are provided.
Cryopreseryation and Germination of Native Aquilegia Species Seeds by Predehydration Treatment
Korean Journal of Plant Resources, volume 14, issue 3, 2001, Pages 251~258
Predehydration effects for cryopreservation in -196
liquid nitrogen were studied in Korean native Aquilegia buergeriana var. oxysepala Kitamura and A. flabellata var. pumila Kudo seeds. Aquilegia species seeds were adjusted to moisture contents between 3.2 and 9.7% by air dry treatments. Seeds were placed in paper envelopes after submerged in liquid nitrogen and rewarming in 38
water. Seeds moisture contents by duration of drying were identified as controlling factors in the survival of Aquilegia species seeds for cryopreservation. Aquilegia species seeds having approximate 5% moisture content were able to withstand cooling to -l96
. Undehydrated seeds of Aquilegia buergeriana var. oxysepala Kitamura after being cryopreservated in liquid nitrogen have a 10.9% of moisture content and show 52.5% in germination. But, Aquilegia buergeriana var. oxysepala Kitamura seeds dehydrated by drying for 60 min. to have 6.0% of moisture content before cryopreservation show 84.7% in germination test. Properly dehydrated seeds after being stored in liquid nitrogen showed over 60% in germination rate and also shows an uniform sprouting time,11~13 days in average. Any morphologically deformity in germinating beds has not been observed. Results from this study suggest that Aquilegia species seeds can cryopreservation in liquid nitrogen if the seed moisture content is controled by a proper amount of dehydration.

Korean Journal of Plant Resources, volume 14, issue 3, 2001, Pages 277~285
This study was conducted to know about the distribution of naturalized plants growing in Jeiu Island. A field survey and flora lists of relevant literatures were also investigated. The results obtained from this study were as follows: Definition of naturalized plants was determined in this study as “non-native species in Korea which have been introduced anthropologically or naturally and can reproduce and survive in wild habitats by themselves.” It was suggested that the number of naturalized plants in Jeju Island were 31 families, 111 genera, 188 taxa including 178 species, 10 varieties. Family Compositae and Gramineae covered 23% and 14% of naturalized plants, respectively. The number of naturalized plants in Jeju Island were 188 taxa ; 97 taxa in the whole south Korea,39 taxa in the southern part of Korea,15 taxa in the central part of Korea, and 37 taxa only in Jeju.
Survey of Barley (Hordeum vulgare L.) Cultivars Resistance to Mosaic Viruses and Areas Infected with Soil-borne Barley Mosaic Viruses
Korean Journal of Plant Resources, volume 14, issue 3, 2001, Pages 286~294
Soil-borne barley viruses were investigated in 42 regions during 1999-2003, in Korea. BaYMV, BaMMV and SbWMV symptoms were found in 37 regions. Crops resistance to mosaic viruses were investigated by growing them on 10 regions infected with soil-borne viruses. It was found that 10 unhulled barley, 6-beer bar]ey, 16 rye and 2 wheat species showed resistance to virus. Most of 15 Japanese cultivars showed infection symptoms but many of them showed relatively higher resistance in Ikasan, Youngkwang and Yesan areas region. Mixed virus infection was investigated and it was found that inter-regional species except in 10 areas, were mix infected with BaYMV and BaMMV. But in Youngkwang area all of crop species except Secheon-6 were infected only with BaYMV. Japanese cultivars were mixed infected with BaMMV and BaYMV except at Yesan that were infected only with BaYMV.
