The study is aimed to obtain the basic data for developing new variations of wild spring orchid. The results was investigated the capsules' formational characteristics and the germination ratio after having been self-pollinated by dividing the flowering period into the 5 stages into budding time, semi-flowering, full-flowering, 10 days after flowering, and 20 days after flowering. The fruit setting ratio was the highest as 100% in the plant which had been pollinated 20 days after the flowering, while the weight of the capsule was heaviest in the orchid which had been pollinated in semi-flowering period. As the result of investigating the germination ratio by dividing the period into 5 stages, it was the highest in the plant which had been pollinated during the semi-flowering period, and in the result of investigating the germination ratio by dividing the seeds harvesting days into the 3 stages, such as, 150 days, 165 days and 180 days after the pollination, it was highest as 5% in the orchid whose seeds had been harvested 150 days after the pollination. In the result of examining the germination ratio of the seeds treated with NaOCl, the those treated with 2% of NaOCl showed the highest as 67% in the germination ratio.

In this study, we investigated the potential of 70% ethanol extracts from wild edible plants (Pueraria lobata sprout, Rosa multiflora sprout, Artemisia princeps leaf, Diospyros kaki leaf, Morus alba leaf, Robinia pseudoacacia flower, Inula britannica var. japonica flower), as natural antioxidants. The antioxidant contents and activities of extracts were examined using various methods. The measurements of total polyphenol content revealed that Rosa multiflora sprout extract had the highest value and total flavonoid content showed that Diospyros kaki leaf extract had the highest value. Antioxidant activities were the highest in Rosa multiflora sprout for DPPH (IC₅₀ 232.52 ㎍/mL), ABTS⁺ (IC₅₀ 470.10 ㎍/mL), superoxide^- (IC₅₀ 431.88 ㎍/mL), nitrite (IC₅₀ 363.38 ㎍/mL) scavenging activity, and reducing power (2.47 O.D.). These results suggest that the ethanolic extract of Rosa multiflora sprout is a potential source of natural antioxidants.

Yellow, one of the five direction colors, is a prevailing color in artificial dyeing. The color has implied and symbolized wealth and power since ancient times. Yellow has been extracted mainly from flowers. Shapes, colors and scents of flowers not only have enriched emotional mentality, but have also been used for medicinal herbs, and dyestuff since the very old days. Coloring matter from flowers is very beautiful, and it has been used for dyeing textiles. Textile dyeing have formed a color culture and developed a dyeing culture since ancient times. Flowers include a variety of color matters, and can be easily obtained around us. Therefore, flowers have been a widespread natural dyestuff. It is well known that beautiful colors can be extracted from flowers, which are eco-friendly and non-polluting. In addition, flowers are easily provided. In this study, yellow wild flowers were selected as subjects. Seven flowers with color matters distiguishable through the naked eye were used: Korean forsythia, golden-wave, Mongolian dandelion, sunflower, conflower, chelidonium and chrysanthemum. Coloring matters were extracted from the seven flowers, which have been used to create a variety of colors through various dyestuffs; and the colors have been analyzed and presented. Dyeing and coloring matters were tested and analyzed, and several types of dyestuff had also been scientifically measured after treatment.

Basil(Ocimum basilicum L.) is an annual herb that grows wild in hot and humid regions such as tropical Asia and Africa. This study was carried out for resource discovery, propagation, and DB construction of aromatic plants. In order to evaluate the genetic characteristics, 28 kinds of basil seeds were supplied from the Center for Genetic Resources. For basil characteristics, planting date, plant height, growth shape, leaf length, leaf shape, petiole color, petiole, stem color, flower color, after harvest, Ml length including roots, flower length, stem thickness and biological weight were measured. For anthocyanin analysis, only basil with purple color was selected, anthocyanins were extracted with 60% ethanol containing 1% citric acid, a standard quantitative curve was prepared with cyanidin-3-glucoside, and absorbance was measured at 525 nm. Basil planting started around June 16, and the flowering period lasted for a total of 18 days from July 19 to August 5. On August 6, when flowering was completed, morphological characteristics including flower color were measured at the site by an object. The measured basil plant length was 26.6-59.6 cm, leaf length 2.0-7.9 cm, leaf width 0.7-5.2 cm, and petiole 1.3-3.9 cm. The growth pattern of basil was generally straight, medium in shape. The color of the leaves was observed evenly by mixed green, purple, purple and green, and the recesses in the shape of the leaf were also conspicuously observed. A total of three basil flower colors were observed: white, light pink(149P 10P/84), and purple(37V 2.5RP 4/12). During the second growth survey after harvest, the total length including the basil roots is 26.7-52.0 cm, the flower length is 8.2-29.3cm, the stem thickness is 7.1-15.9mm, the number of stem nodes is 3-12 nodes, and the total weight of the basil was measured to be about 218-1540 g. There are a total of 16 types of basil expressed in purple, and the anthocyanin content was measured to be 73.74 ~ 380.72 mg/100g.

14 kinds of perennial flower sods, including 10 Korean native wild perennial flowers such as Lychnis cognata, Achillea sibirica, Sedum spectabile, Sedum takesimense etc. were made with basal sheets of nonwoven fabric or jute fabric. Growth of plants planted on bark was better than that of planted on soil of open area. The plants planted on bark also showed difference in growth rate by the kinds of used basal sheets. In general, the growth of plants was good when nonwoven fabric was used as basal sheet instead of jute fabric. When jute fabric was used as basal sheet, It was severely decayed during growth period resulting in great decreasing of root sticking capacity to basal sheet. It was shown that the procumbent plants such as Tymus quinquecostatus, Ixeris stolonifera, Sedum oryzifolium, Sedum polystichoides having lower plant height and better ground coverage ability compared with upright plants such as Sedum spectabile and Aster glehni were more suitable for floral sod production.
