This study was conducted to investigate the utilization, the prospect and the need of improvement of Lycoris radiata, for the purpose of making it better a flowering plant and giving a right reorientation in the breeding. Lycoris radiata was rated high as material for flower arrangement, flower basket and fancy, and it was rated highest as material for flower bed. In case of flower arrangement and flower basket, flower designers could make good use of seasonal image, the number of flowerets, flower color. However, flowering time, the size of flower, vase -life and convenience of purchase were considered to be in need of improvement. Flowering time, the size of flower, flower color, the number of flowerlets, the strenth of stem and seasonal image were rated high as materials for flower bed and fancy but flower color, vase life, leaf length, leaf width and discrepancy in emergence of flower and leaf were considered to be in need of improvement.

This study was surveyed to know utilization of the in graveyard the military and the police(MP), the catholic graveyard(CG) and graveyard of mausoleum(GM). The items of investigation were the ratio, kinds of flower, color of cut flower and form of offering a bunch of flowers. The time of investigation were New Year's day, Chusok(the korean thanksgiving day) and a weekday. On a week day, the ratio of offering a bunch of flowers was 6.3 perrcent in GM. CG and GM were 2 and 6 percent, respectively, On Chusok MP was 9 percent, CG was 25 percent and GM was 55.9 percent. On New Year's Day MP was 17.9 percent, CG was 43.3 percent and GM was 49.8 percent. Except for GM, when we compared the chusok with a week day, they were offered 12-24 times. Of the kinds of cut flower offered a bunch of flowers, chrysanthemum was 60 percent or more without regard to MP, CG and GM. About color of cut flower, white was 39.2 percent or more and yellow was 8.8 percent or more. Most of used colors were white and yellow. And they were 48 percent or more. That of on a week day was low remarkably. The form of offered flower on a graveyard were various: a flower, a basket of flower, a potflower, a flower in a case of glass, and a flower in a vase. Of that, a bunch of flowers were 33 percent or more in GC, MP and CG. KEY WORDS : flower, graveyard, new year's day, chusok, chrysanthemum

This study was conducted to gather the basic data on the increase of utilization for the Japanese staunton vine (Stauntonia hexaphylla), native plants which were grown in the southern districts in Korea. We have also determined their partial physical and chemical compositions and their physiological activities. Vitamin C contents in fruit skin was 85.23 mg/100g, and that in flesh was 61.67 mg/100g. Total amino acids contents in fruit skin increased much more by 762.72 mg/100g DW compared to that in flesh by 434.05 mg/100g DW. Inorganic matter contents were more increased in the fruit skin(108.48 mg/ℓ) and its main components were K (76.53 mg/ℓ), Ca (20.20 mg/ℓ) and Mg (6.22 mg/ℓ). Total phenol compound and flavonoid contents in 1,000 mg/ℓ methanol extracts were 7.3-9.6 mg/L and 5.1-6.7 mg/ℓ. Nitrite radical scavenging activity in 4,000 mg/ℓ methanol extracts of fruit skin and flesh for Stauntonia hexaphylla were 79.5% and 77.8%, however, that in seeds was 17.1%. Overall mushroom tyrosinase inhibition activity (% of control) was less than 10.8%. Anti-microbial activities of methanol extracts from the fruit skin against the gram negative and positive microbial strains were not significant in the lower concentration of extracting solution, however, that from flesh and seeds in terms of the inhibition diameter were 8.91∼12.25 mm. 남해안 지역에 자생하고 있는 멀꿀의 이용도를 높이기 위한 기초자료 확보 측면에서 부위별 성분함량과 생리활성을 조사하였다. 비타민 C는 과피에 85.23 mg/100g, 과육에 61.67 mg/100g가 함유되어 있었다. 총 아미노산은 과육 434.05 mg/100g DW에 비해 과피에 762.72 mg/100g DW으로 많았다. 무기물 함량은 과피(108.48 mg/ℓ)에 많았으며, K(76.53 mg/ℓ), Ca(20.20 mg/ℓ) 및 Mg(6.22 mg/ℓ)가 대부분을 차지했다. 메탄올 추출물 1,000 mg/ℓ일 때 총 페놀화합물은 7.3-9.6 mg/ℓ였으며, 총 플라보노이드 함량은 5.1-6.7 mg/ℓ였다. 멀꿀 메탄올 추출물 4,000 mg/ℓ의 아질산염소거는 과피와 과육은 각각 79.5, 77.8%인데 비해 종자는 17.1%였으며, tyrosinase 활성의 저해효과는 10.8%이하를 나타냈다. 항균활성은 그람양성균과 그람음성균 모두 과피 메탄올 추출물의 저 농도에서는 나타나지 않은 경우도 있었으나 과육과 종자 추출물에서는 저해환 직경이 8.91∼12.25 mm을 나타냈다.

This study was carried out to investigate into the dyeability of ramie fabrics using theextract of native plant, red-dye madder (Rubia akane Nakai) in different conditions. Surfacecolor of ramie fabrics dyed with extracts from red-dye madder plants showed an order ofdescent YR. However, it was changed by the different mordants. Surface color of ramiefabrics treated with FeSO4, SnCl4, and tartaric acid was an order of descent Y, and thattreated with the ashes of common camellia, and bean straw was an order of descent R. Athigher temperatures, surface color and coloring matter concentration of ramie fabrics wereas follows that values of a increased, however, values of b decreased and values of L lowered.Coloring matter concentration increased in the order of 70℃, 90℃, and 60℃, and so on.Dyeing colors on the ramie fabrics showed an order of descent Y by pH 4 and 9 in dyestuffssolutions. Coloring matter concentration in terms of K/S values, more or less, was increasedat strong acids. Surface color by the concentration of dyestuffs solutions showed an order ofdescent YR irrelevant to the concentration of dyestuffs solutions. Coloring matterconcentration was increased at higher concentrations of dyestuffs solutions. Ten minuteswas sufficient for the dyeing of ramie fabrics in terms of surface color and coloring matter concentration.

朴潤点 圓光大學校大學院 1986 學位論叢 Vol.16 No.-

The present works were carried out to survey the morphological characteristics and biological environment of native Lycoris radiata HERB. and to find out the multiple propagation method of them. The results obtained are as follows ; 1. Five flowers bloomed on the top of about 50cm-tall-f1ower stalk and their flowering was umbel-like shape. The phyllotaxy of the leaves was alternate and their shape was linear or lanceolate with deep green colour. The colour of the bulb was dark brown. and its shape was elliptic. The average weight of the bulb was 19.3g. Full flowering appeared around Sept. 20. At the middle of Oct., when there was no longer flowering, the new leaves began to shoot forth and withered completely late in May the next year. There were 3 or 4 seeds in a capsule and the average weight of the seed was O.65g. The flower bud initiation began around May 15 and ended about June 18. 2. The meiosis prophase of microspore mother cell was about Aug. 17 and the .rneiosis began around Aug. 30, but the process of it was abnormal. The megaspore mother cell developed fully Aug. 17 and its tetrad happened about Sept. 4. 3. The minimum air temperature at the native habitat was -4.9°C in Jan. and the maximum was 29.2°C in August. The soil temperature was above the minimum air temperature but it was below the average air temperature. The relative humidity of the air was 85.4% to 88.8% in summer and above 80% even in Jan. or Feb. The light intensity in the native habitat was 10.5 Klux in March and 1.3 Klux from June to Sept.. The light intensity in the open area was 130 Klux in June. 4. The habitat soil acidity was from pH 5.23 to pH 6.00. Humus contents, total N, P_(2)O_(5), SiO₂, K, Ca, Mg, H, and C.E.C. were 5.46%, 0.44%. 32.59ppm, 89.12ppm, 0.58 me/l00g, 6.49me/l00g, 2.47 me/100g, 3.9 me/l00g, and 14.04 me/l00g, respectively. Most of the soil texture in the habitat regions was sandy loam, and the soil moisture was 45.59% in July and 17.5% in March. 5. The trees around the habitat regions were such deciduous broad-leaved trees as Orixa japonica THuNB., Carpinus tschonoskii MAx., Celtis sinensis P_(ERS)., Plat yearya strobilacea S. et Z., Cornus controuersa H_(EMSL). etc.. This fact gives a hint that they may be indicator plants. 6. The north geographical distribution limit line of Lycoris radiata H_(ERB). was Magoksa-temple in Kongju. The plants grew around the temples and south-west coast areas of Korean peninsula, In Mt, Dosol, they are found from 20m to 180m hight above sea level, mainly in the southern east facing slope. 7. Bulblet formation number was larger in the outer part of the scale. But the development and hypertrophy plump were good in the middle part. The contents of reducing sugar and starch were the largest in the middle part, but those of nonreducing sugar and total sugar were the largest in the outer part. 8. Bulblet formation and rooting were best in the Perlite. The hot water treatment was very effective for the bulblet formation. rooting and leaf emergence than the control. 9. The curing at 25°C for 5 days was very effective for the bulb formation. and the curing at 30°C on the 5 th or 6 th day was effective for the growth of roots. The alternating temperature between 25°C and 30°C for 12 hours had good effect on bulb formation and rooting. 10. The more times the basal plate was cutted, the higher was the ratio of the bulblet formation. Whether there was light or not didn't have great effect on bulblet formation. But darkness had good effect on bulblet hypertrophy plump and rooting. 11. Notching method was better than scooping or coring in the bulblet formation and root growth. The ratio of bulblet formation was low in coring, and the bulblet hypertrophy plump was bad in scooping. 12. When the bulb was more cutted. the number of bulblet formation increased. But the growth of their roots was not good. In order to produce good bu lbl e ts , the bulbs divided into four parts was most advantageous. 13. In notching. the bulb divided into two parts produced good rooting but bulblet formation was not good. The more times the bulb was divided, the higher was the bulblet formation ratio. The higher bulblet formation ratio was observed in the deep division status. In notching, the bulblet formation and rooting was good when basal part was planted downward direction. The better bulblet formation and rooting was observed in the thicker-moulding. 14. Adaxial side of scale began to bulge on the 5 th day after scale-stem cutting, and the bulged part continued division to form the perfect bulblet on the 30th day. 15. In scale tissue culture. the callus formation was most excellent in the basal part, and the combination kinetin l0mg/ℓ + 2.4-D 2mg/ℓ + NAA 2mg/ℓ was the best for the callus formation. On the other hand, in the combination kinetin 3 mg/ℓ + 2.4-D 2 mg/ℓ + NAA 2 mg/ℓ no callus formation was observed.

This study was carried out to investigate the utilization of pruned branch of a peach treeas natural dyeing material. The dyestuff was extracted from pruned branch of a peach tree.we examined the dyeing ability on silk and cotten fabrics. The surface color of silk fabricsdiffered depending on mordants. E values in treatments of mordants ranged from 11.63 to30.86 as compared to non-treatment. Dyeing properties of cotten fabrics were improved witha treatment of sulfate of iron as compared with of non-treatment. The values a increasedwhen the slaked lime and sodium hydroxide were used as mordants, while the values bincreased when copper sulfate, alum and apple vinegar were used. We investigated thesurface colors of silk and cotten fabrics after washing three times. In general, the surfacecolors of silk and cotten fabrics between the treatments of all mordants and non-treatmentwere diminished by the washing. We also investigated the surface colors of silk and cottenfabrics when those were washed and treated by the light after soaking those into various pHsolutions. The surface colors of silk and cotten fabrics were considerably preserved by thewashing, the light and pH concentration. In conclusion, our results suggest that the dyestuffsfrom pruning branch of a peach tree would be useful as a natural dyeing material using theoptimized conditions for silk and cotten dyeing. 복숭아나무 전정 과정에서 발생하는 부산물인 절지의 천연염료로서 이용성을 조사하였다. 복숭아 가지 추출물로 견과 면직물을 염색한 결과 견직물의 표면색은 매염제에 따른 차이가 있는 가운데 무염색포에 비해 색차(△E값)가 11.63에서 30.86까지 나타났다. 면직물은 무매염시 17.71에서 황산철 매염시 40.41로 견직물 보다 염색성이 좋은 것으로 나타났다. 매염제에 따라서는 소석회와 가성소다 매염시 a값이 높게 나타났으며, 황산구리와 명반, 식초 매염 시는 b값이 높게 나타났다. 세탁을 3회 실시한 뒤 표면색을 조사한 결과 매염제에 따른 차이는 다소 있었으나 전체적으로 무염색구와의 사이에 색차가 줄어든 것으로 나타나 세탁 견뢰도는 다소 약한 것으로 나타났다. pH가 다른 수세액에 의한 수세 및 일광 처리 후 표면색의 변화를 조사한 결과 처리 전후간에 차이가 적어 pH에 대한 견뢰도 및 일광 견뢰도는 비교적 좋은 것으로 나타났다.
