Source and Sink Relationship in Diallell Grafting among Sweet potato Cultivars
Korean Journal of Plant Resources, volume 14, issue 2, 2001, Pages 89~93
To obtain the basic information for varietal improvement and cultural practice, source and sink relationship in the diallel grafting was analyzed among five sweet potato cultivars, Yulmi, Shinyulmi, Gunmi, Hongmi and Seonmi, whose source and sink capacities are different one another. General grafting effect(GGE), specific grafting effect(SGE) and reciprocal grafting effect(RGE) of top weight, tuberous root weight and total weight showed considerable differences. Grafting decreased total dry weight but its effect was different among grafting combinations. Growth and dry matter production of top were affected more by scion, while those of underground were influenced more by stock. Shinyulmi which has great potential source and sink capacities resulted the highest total dry weight, while Hongmi and Yulmi which have low potential source capacity resulted the lowest total dry weight.
The Growth Characteristics and Yield of Treatment Onion (Allium cepa L.)Seed in Direct Sowing Cultivation
Korean Journal of Plant Resources, volume 14, issue 2, 2001, Pages 94~101
This study was intended to evaluate the relationship environmental condition and growth characteristics of seed treatment seed in direct sowing with different sowing date, and to suggest new cultivation model. The emergence percentage and hours were down as the delayed sowing date. Optimum sowing time was Sep. 10, and sowing must end before Sep. 20 for safety yield. When did sowing ended before Sep.20 in direct sowing cultivation, the seedling growth(SG) and No of roots of direct sowing seedling were larger than transplanting cultivation . At March 8 evaluated seedling, the SG of direct sowing seedling was higher than transplanting, and at Sep. 2(1 those were similar. The missing plant rate in transplanting cultivation was under 3 %, and that in direct sowing cultivation was about 13∼18%, and the extent were sever as delayed sowing date. The bulb fresh weight was decreased as delayed sowing, and those in direct sowing and transplanting cultivation were 230, 217g, respectively. The blot rate was high in direct sowing cultivation, and that was decreased as delayed sowing. The yield in direct sowing and transplanting cultivation were 5,134, 5,300kg, respectively, and those were decreased as delayed sowing. The average yield in early and medium-late maturity cultivars were 3,750, 4,908kg, respectively, and Sonic was highest yield in early maturity cultivars and Nongwoodego was highest in medium-late maturity cultivars. The emergence weed were 9 species as Loportea bulbifera Weddell and others, and Loported bulbifera Weddell, Digitaria violascens Link and Persicaria longiseta Kitagawa were dominant species in direct sowing cultivation with black hole vinyl mulching.
Microscopical Characteristics of Softwood Sawdusts Cultivated with Enokitake (Flammulina velutipes)
Korean Journal of Plant Resources, volume 14, issue 2, 2001, Pages 102~107
This study was carried out to explore for the possibility of recycling the pine wood sawdusts for the substrate for enokitake (Flammulina velutipes) cultivation. The wood species of sawdusts cultivated for enokitake mushroom were identified mostly as hard pine (Pinus spp.). Distribution of enokitake hyphae was restricted to ray parenchymas and tracheids exposed to fungi. Nevertheless, degree of cell wall degradation by enokitake was slight. Light microscopic observation showed the thinning of secondary cell wall in some tracheids. Under polarized microscopy the 1()ss of birefringence was observed only in a few latewood tracheids. All the middle lamella remained intact. The present work showed clearly that pine sawdusts used as substrate for enokitake cultivation held enough cell wall materials for mushroom cultivation. The relative resistance of softwood cell walls against enokitake fungus was also discussed.
The effect of extracts of industrial plant resources on germination and growth of Raphanus sativus L.
Korean Journal of Plant Resources, volume 14, issue 2, 2001, Pages 108~115
For determining the effect of extracts exudated from ten industrial plant resources on germination and early growth of shoot and root of radish the allelopathic compounds screened. Germination rate and seedling growth of radish differed depending on plant species and extract concentration. Lower levels of 1% extracts exudated from industrial plant resources promoted the rate of germination of radish while higher levels of 10% extract inhibited the rate of germination. Germination rate, shoot growth and root growth of radish in higher concentration of extract also differed depending on the plant species exudated and extract concentraton of industrial plant resources. Higher concentration of extracts from Xanthium strutnarium L. Angellica gigas Nakai, and Solanum nigrum L. were completely inhibited the germination while those from Cichorium intybus L., and Polygonatum officinale Allioni were not inhibited. Extracts exudated from Xanthium strutnarium L, Angellica gigas Nakai, and Solanum nigrum L. showed the strong inhibition of shoot and root growth of radish while those from Cichorium intybus L., and Polygonatum officinale Allioni did not show the bioactivity in shoot and root growth of radish..
Screening of the Antioxidant Defense Systems from Parthenocisuss tricuspidata PLANCH
Korean Journal of Plant Resources, volume 14, issue 2, 2001, Pages 116~123
The non-enzymatic antioxidants and antioxidant enzyme from the extracts of Parthenocissus tricuspidata PLANCH. were examined in order to utilize natural product for cerchemopreventive agents. The antioxidant potential and enzyme activities on plant positions in the extracts of Parthenocisuss tricuspidata PLANCH. showed considerable differences. The antioxidant activity of the leaf extracts by Ethyl acetate fractions of Parthenocisuss tricuspidata PLANCH. was the highest among three positions (
). The highest activities showed in S-5 (in leaf), S-4 (in stem) and S-3 (in root) fraction by Silicagel column chromatography and the antioxidant activity showed, in purified extract of each positions,
(in stem) and
(in root) respectively. The activities of DPPH by LH-20 column chromatography revealed much higher than those by silica-gel column chromatography. These were identified as the phenolic compounds known as antioxidant compounds such as Benzoic acid(Gallic acid), 1-methyl-3-(2-phenylethen) benzene, phloroglucinol and 1,2-dihydroxy-4-(1-propyl)benzene by GC/MS. POD activities in the stem and root were higher than in the leaf. SOD activity was highest in the leaf, stem and root activity was comparatively low. Especially, SOD activity in leaf was over 2 times higher than root.
Effect of Nursery Period on Growth and Yield in Alisma plantago
Korean Journal of Plant Resources, volume 14, issue 2, 2001, Pages 124~128
This study was carried out to determine the effect of various period of nursery on the growth, yield and labor saving of work by truncation on floral axis of Alisma plantago in the southern coastal areas of Korea. The growth characteristics such as p]ant height, number of leaves were more increased at 20 days of nursery period plot them that of nursery periods. The dried-root yield was highest then but the floral axis was lowest at the 20 days of nursery period plot then that of other nursery periods. Therefore optimum period on nursery of Alisma plantago was 20days of nursery period in southern areas of Korea.

Korean Journal of Plant Resources, volume 14, issue 2, 2001, Pages 157~162
Korean native Orostachys species collected from 22 regions investigated morphological characters.O. japonicus species(No.3∼No.9) were similar leaf morphology and characterized by lanceolate leaves, cuspidate leaf apex.O. malacophyllus species(No.12∼No. 17) were morphologically characterized by obovate leaves and acute leaf apex. This species could be differentiate from other species by no thorn and leaf outlines formed by densely populated red dots.O. iwarenge species(No.18∼No.22) were diversified, such as obovate and elliptical leaves with acute, obtuse and round leaf apices. However, this species could be differentiate from other species bl'no thorn and grey powdery green colored leaves. Species collected from Maemuldo(No. 10) and Pocheon(No. 11) was assumed that these 2 species could be the new species which were not named classified.
Studies on Flowering Habit and Cross-Fertility of some local cultivars in Angelica gigas NAKAI
Korean Journal of Plant Resources, volume 14, issue 2, 2001, Pages 163~168
This study was conducted to obtain basic information on cross breeding for developing bolting resistant variety of Angelica gigas NAKAI which has been subjected to severe yield reduction resulted from flower-stalk initiation during the growth. Compatibility of selfing and/or crossing pollination among 5 local cultivars were tested. Results obtained are summarized as follows. In case of three year old plant, all cultivars emerged March 14 and bolted from May 12 to May 13. Ponghwa cultivar was flowered 3 to 5 days earlier than other cultivars. Flower duration continued 41 to 43 days. Interval of flowering date from main stem to first primary branch, from first to second or second to third primary branch was 9 to 13 days. Emergency of stamen proceeded 4~8 days of pistil initiation demonstrating that Angelica gigas NAKAI is protandrous plant. Furthermore initiation of first pistil was 1~4days later than formation of last stamen in the same flower cluster. Percent pollination of Angelica gigas NAKAI was 52% under natural condition, so called open-pollination, but bagging by enveloping flowers was as low as 0.4~2.4%. In the result of compatibility test, all local cultivars tend to show both of self-and cross-compatibility. Inpollination, ‘Muju’
‘Muju’combination showed highest fertility up to 40.8% whereases cross pollination, ‘Pyeongchang’
‘Inje’combination, showed 67.0% fertility.

Presown Seed Treatments to Promote Seed Germination of Zoysiagrass (Zoysia japonica)
Korean Journal of Plant Resources, volume 14, issue 2, 2001, Pages 175~181
Dormancy of intact zoysiagrass seeds hinders its seed propagation in which presowing seed treatment must be done to overcome it. The study was done to remodel the presowing treatments of zoysiagrass seeds by determining the treatment effects of seedcoat softening, prechilling, drying and combined light treatment with them or during germination stage. Seedcoat softening with different chemicals (NaOH 20%, KOH 20%,
, acetone 20%) and periods (10, 30, 60 min.), prechilling with different periods at 3
, and drying with 4 hours at 35
was done. Light sources were also applied with 660 nm red LED light, commercial fluorescent and incandescent light and darkness. Germination test was done in alternative day and night temperature of 35 and 2
to check the daily germination rates. With seeds treated with NaOH 20% for 30 minutes, red and incandescent light showing similar responses inclined their germination rates compared to dark conditions. Drying resulted in its higher rate than non-drying but fluorescent light treatment forced during drying more enhanced the rate than red light. While mean germination rate considering all the seedcoat softening treatment periods was the greatest in
in comparison with NaOH, KOH and acetone, NaOH treatment for 30 minutes showed the best rate among the all the treatment levels. In the conditions of sowing them to no-mulching field, presowing treatment procedure of zoysiagrass seeds was remodeled: the seedcoat softening treatment with NaOH 20% for 30 minutes was done, washed, and chilled at 3
for 2 weeks before dried under 4 hour fluorescent light illumination at 35
