Studies on the Increase of Germination Percent of Angelica gigas Nakai I. Germination Characteristics and Cause of Lower Germination Percent
Cho, Seon-Haeng ; Kim, Ki-June ;
Korean Journal of Medicinal Crop Science, volume 1, issue 1, 1993, Pages 3~9
This experiment was conducted to study germination characteristics and the decrease cause of germination percent in Angelica gigas Nakai seed. The emergence percent of winter sowing was higher than that of spring sowing as 66.6% and 41.1%, respectively, and the first emergence date was also earlier in winter sowing. The seed germination speed, percent and coefficent showed the highest value at
of incubation temperature, but lower value at
. The water uptake speed was increased along with increasing water temperature. The weight of imbibed seed at germination was 3.4times higher based on the weight of intact dry seed and 2.3times on removal of seed coat. In terms of length of seed was large, the germination percent was higher. The germination percent of brown colored seeds showed higher value than that of green colored seeds. The prolonged storage period decreased germination percent. When A.gigas seeds stored at room temperatue for 2years, the seeds were lost their viability. The biological inhibition effect of methanol, water and ether extract on the germination and growth of A.gigas and lettuce seed showed the highest value in the methanol extract, followed by water extract and the least in ether extract.

This study was carried out to identify the effect of seed gathering time and after-ripening on Paeonia lactiflora Pall (PL) seed emergence, and to establish optimal seed gathering time and sowing time. We used two local cultivar of PL ; Punggi and Uisung. Seeds were gathered 6 times from 5th July to 25th August in 1992. The seeds of Punggi local cultivar were planted by the planting density of
after treatment of 7 ways ; without after-ripening, with after-ripening for 10, 20, 30 days without or with capsule. We investigated the change of 100 grains weight of PL seed by the passage of time and emergence rate after treatment. The seed weight of Punggi was heavier than that of Uisung and the seed weight was maximzed at 25th July both of the two, and then decreased by the passage of time. The seed emergence rate of Punggi gathered at 5th July was showed 7.8% and the seed emergence of Uisung was later 10 days than that of Punggi. The maximum emergence rate of two local cultivars was the highest in gathering the seeds on the 15th of August. In gathering the seeds without and with capsule, the emergence rate of seeds sowed with after-ripening was higher than that of seeds sowed immediately after gathering the seeds without after-ripening when the seeds gathered between 5th July and 5th August. In after-ripening with out and with capsule, the emergence rate of 10 days after-ripening seeds was less than that of 20 and 30 days after-ripening seeds after the seeds gathered on the 5th and 15th of July. Difference of the emergence rate of seeds by after-ripening time did not show when the seeds gathered after 25th July.
Study on the Propagation of Acanthopanax Plants II. Characteristics of Seed and Growth of Embryo in Stratifying Treatment
Ahn, Sang-Deuk ;
Korean Journal of Medicinal Crop Science, volume 1, issue 1, 1993, Pages 16~23
Seeds of Acanthopanx plants need about 2 years to germinate after sowing even if full matured fruits were harvested. I leave a room for doubt that this phenomenon could be brought by the immatured embryo in seed. If it is true, stratification method for the seed propagation of Acanthopanax plants would be used more effectively to promote the growth of embryo in relatively short time. Before stratification, seeds were devided into two parts. One of them was treated for 24hrs in the concentration of
100 ppm. After stratification of non-treated and treated seeds, seeds for microtechnique were taken on interval of one month for three months, and fixed in Farmer's solution. The seed sizes of Acanthopanax plants were in biggest order A. sessiliflorus, A. seoulense, A. chiisanensis, A. koreanum and A. sieboldianum. The dehiscence phenomenon of seed coat didn't show in most of the seeds that stratified, but A. koreanum only dehisced in seeds treated in
100ppm. The embryos of the stratified seeds that treated in
showed nomal growth, complete cotyledons and procambium in hypocotyl in any species, but the non-treated seeds could not expect the germination after sowing due to poor growing of the embryo in all species. In view of the results so far achieved, it has taken long times from sowing to germinate because the seed of Acanthopanax plants has immatured embryo.

This study was conducted to select thin-shelled and high-yielding lines in job's-tears. Two breeding lines of Suwon 3 and Suwon 6 were selected from the local collections. These two lines were tested and investigated on their characteristics under the field condition. The heading date of Suwon 3 and Suwon 6 was later one or two days, but the maturity date was one or two days earlier than that of check variety Kim-jejong, respectively. The number of grains per hill of Suwon 3, Suwon 6 was 50%, 49% greater and the milling rate was 3.8%, 5.6% higher than that of check variety, respectively. Althought 1000 grain weight of Suwon 3 and Suwon 6 was 20g lighter and the rate of ripeness was 6%, 12% lower, the raw grain yield was 22%, 20% higher than that of check variety, respectively. The thickness of seed coat of Suwon 3 and Suwon 6 was thiner and the hardness of seed coat was lower than that of check variety, therefore the milling time was decreased 12%, 7% compare to check variety, respectively. The crude protein contents of Suwon 3 and Suwon 6 was slightly higher and the amino acid composition of Suwon 6 was similar to Kimjejong, but Suwon 3 was lower than that of check variety.

The low seed propagation is one of the problem needed a lot of seed tuber for the propagation in yam. Therefore this experiment was carried out to understand the possiblility of seed tuber propagation by tissue culture of yam. In-vitro stem node of yam was cultured by concentration treatments of 1/2, 1/4 and 1/8 with MS medium additted with each concentration levels of IAA, NAA, IBA, kinetin and BA. Acorrding to the Iower concentration than MS medium, length of shoots was promoted, leaf emergence shoots and rooting shoots were increased at 1/8 MS medium during the culturing period of stem node in yam. Fixed IBA and kinetin under the concentration of MS mdeium was inhibited severely by the heigh concentration additted with lAA
. But fixed IBA
with concentration of 1/8MS medium was remarkably promoted leaf emergence shoots and rooting shoots by
of additted lAA and NAA. Percentage of induced shoots was increased by combination treatments of lAA.
, also leaf emergence shoots and rooting shoots were promoted by combination treatments of lAA

Present experiments were carried out to examine the effect of plant growthregulators for callus induction and plantlet regeneration through leaf tissue culture of Scutellaria baicalensis GEORGI. The results indicated that Callus was induced well on MS medium supplemented with 0.5mg/L NAA or 0.5mg/L NAA Plus 0.5mg/L zeatin. MS medium supplemented with 1.0mg/L BAP plus 0. 5mg /L NAA or 1. 0mg /L zeatin Plus 0.5mg /L NAA and 1.0mg /L NAA were the most effective for plant regeneration. Thin layer chromatogram of baicalin component (Rf 0.39) was observed from callus cultured on MS medium containing 0.5mg /L NAA plus 0.5mg /L zeatin.

Kim, Kwan-Su ; Chae, Young-Am ;
Korean Journal of Medicinal Crop Science, volume 1, issue 1, 1993, Pages 49~57
Seedling of Aralia continentalis is more effective method rather than use of vegetative organ for mass propagation. However, lower germination rate is the main problem for seeding. In this study, we analyzed substances in aim to relate to germination process. The results indicated that longer period of stratification brought lower amount of phenolic compounds in the seeds and both promoting and inhibiting substances were at very low level or gradually disappeared.
Effects of Carbon and Nitrogen Sources on the Essential Oil Production and Its Composition in Callus Culture of Mentha piperita L.
Oh, Byuong-In ; Chae, Young-Am ;
Korean Journal of Medicinal Crop Science, volume 1, issue 1, 1993, Pages 58~62
The effects of carbohydrate sources(sucrose, glucose) and ratio of ammonia to nitrate on essential oil production and its com- positions in the callus culture of Mentha piperita L. were studied. An ammonia : nitrate ratio of 1 :2 was more effective for essential oil production regardless of the media used ; Lin-Staba(LS) and modify Murashige-Skoog(MS) medium. Menthol biosynthesis was enhanced when ratio of ammonia to nitrate was 1 :3 in the LS medium while the ratio was 1 :2 in the MS medium. Lower sucrose concentration(20g /1 ) was much better than higher sucrose concentration(30g /1) for both oil and menthol biosynthesis in the LS medium but higher sucrose concentration(30g /1) was more effective for those in the MS medium. When sucrose was replaced with glucose, menthol biosynthesis was sharply decreased or absent regardless of media used.

Korean Journal of Medicinal Crop Science, volume 1, issue 1, 1993, Pages 63~69
Present experiment were attempted to examine in vitro multiplication throughbud culture of Cornus officinalis. Bud derived shoot formation was established successfully on Murashige and Skoog's medium supplemented with
BAP(N-benzyl amino purine). The shoot proliferation increased on the Driver Kuniyuki Walnut medium containing
NAA(Napthalene acetic acid) and
BAP. Addition of 2,4-D(2,4-Dichlorophenoxy acetic acid) to the media produced excessive callus inducton. IAA(Indole-3-acetic acid) and IBA (Indole-3-bu-tyric acid) enhanced multple shooting, and NAA showed callus induction and multiple shooting. Shoot growth was enhanced supplemented with 3% sucrose,
activated charcoal, and 1 / 4MS in organic salts. However, root formation of proliferated shoots was low about 5%

This experiment was carried out to investigate the effect of planting density on thegrowth and yield of Rehmannia glutinosa. A local variety was planted on the 100cm row, with different planting density of 20, 30 and 40 plants per
. Nitrogen, phosporus and potassium fertilizers were applied as 12, 12, and 16 kg /10a, respectively with compost of 1,000kg /10a. Plant height became shorter with increase in the planting density from 20 to 40
. But emergence date, leaf length and width were not significantly changed with planting density. As the planting density was increased, tuber diameter got slender and tuber number was decreased, but tuber length was not affected. The tuber yield was 793kg /10a at the planting density of 20
and it increased 40% at 30
and 45% at 40
Regarding on the farmer's income, optimum planting density was estimated 30

Korean Journal of Medicinal Crop Science, volume 1, issue 1, 1993, Pages 74~80
Survey on the status of cultivation and production of medicinal crop was studied on 18 medicinal herbs and 5 medicinal trees in 66 major crop producing complexes. Native seeds or seedlings of the crops obtained from self-seed or neighbored farmer were cultivated and organic fertilizer was preferred to chemical fertilizer in the complexes. More than 60.7% of farmers were applied compost among the organic fertilizers, while 34.8% of them cultivated without any organic fertilizers. Both of using the compound chemical fertilizers and urea and urea only used were showed 51. 5% and 40.9%, respectively. Ostericum koreanum, Angelica gigas, Phellopterus littoralis, and Bupleurum fulcatum belonging to the family Umbeliferae and Aralia continentalis, Polygonatum sibiricum and Eucommia ulmoides in the complexex were not damaged by insect pests and plant diseases. Mite, aphid, grub, cutworm, onion magot fly and european corn borer were known to as major insect pests and anthracnose, powdery mildew, brown leaf spot, leaf blight and root rot as major plant diseases. Productivity and income of a farm by medicinal crops in the complex were greatly different from seeding time, planting distance, year yielded, and selling routes even in the same cultivation method and in the same cultivated area.
