A new spray chrysanthemum cultivar, 'Golden Festival' was released by National Horticultural Research Institute (NHRI), Rural Development Administration (RDA), Korea in 2007. It was selected from the progenies of open-pollination of 'Torbay' in 2002. Trials were conducted from 2005 to 2007 for evaluation and selection of this cultivar, including shading culture in summer and retarding culture in autumn. The natural flowering time of 'Golden Festival' is late October, but year-round flowering is possible by shading and lighting treatment. The cultivar is semi-double type flowers with bright yellow petals and green flower center. Flower neck and stem are very hardy. The diameter of flower is 56.5 mm. The number of flowers per stem and petals per flower are 12.0 and 93.5, respectively. The days to flowering under the short day treatment is about 50 in spring season.

To study the dyeability(K/S value) and surface color of silk fabrics dyed with Impatiens balsamina extract, its flower, leaf and stem, was extracted by water. This paper investigated some experiments with Impatiens balsamina extract under the various dyeing conditions such as dyeing temperature, dyeing time, repetition of dyeing, dyeing pH with silk fabrics. The results obtained were as follows. 1. It was found that it $\lambdamax$. of silk fabrics dyed with Impatiens balsamina extract was 260nm and its flower, leaf, stem and flowers(white, pink, violet) had same it $\lambdamax$ at 260nm. 2. K/S value was increased when dyeing temperature, repetition of dyeing and time was higher, value of munsell of silk fabrics dyed with Impatiens balsamina extract was yellow-red. dyeing temperature, repetition of dyeing and time was higher, shifted to longer wavelength side. 3. pH added acetic acid was colored reddish yellow-red, but pH added alum was colored yellowish yellow-red in silk fabrics dyed with Impatiens balsamina extract and repetition of dyeing was increased the dye-uptake.

Present studies were carried out to clarify the variation of flowering date in the variants of Korean ginseng Plants. In general, the variation of flowering date of violet-stem variant was found to be mere variable as compared with that of yellow-berry variant. And flowers began to bloom earlier in yellow-berry variant than in violet-stem variant. In violet-stem variant as well as in yellow-berry variant, the flowering date of 5-year old plants was earlier than that of 3- and 4-year old plants. As for the flowering date according to the different lines, the third line was earlier than the first or the fifth line.

A new spray chrysanthemum (Dendranthema grandiflorum) cultivar, 'Magic Yellow' was developed from a cross between 'Artist pink' and 'S03-47' by selection of seedlings and lines at the Flower Research Institute, Gyeongnam Agricultural Research and Extension Services (ARES) from 2003 to 2008. Its characteristics were investigated three times from 2006 to 2008 under condition of forcing culture in spring and retarding culture in autumn. The natural flowering time of 'Magic Yellow' was October 18th, and year-round production was possible by day length treatment. This cultivar has single-type flowers in good harmony with bi-color ray floret and green center. Its flower was 6.0 cm in diameter, and it had 11.4 flowers per stem in autumn. The days to flowering under the short day treatment is about 45 days in spring season, and 'Magic Yellow' showed the vase life of 22.9 days in autumn. This cultivar was registered for the protection in 2008.

Although it is not a landscape crop according to MIFAFF(ministry of agriculture, food and rural affairs), yellow mustard is considered a superb landscape crop because of its growth and flower characteristics. We sowed yellow mustard as a landscape and green manure crop in upland soil (four types of soil texture) in spring. And we studied its flowering characteristics, dry weight, and nitrogen yield. The growths of yellow mustard were possible in every soil ranging from sandy soil to clay loam. Its height was 54.1 ~ 76.1cm and the number of node per hill was 11.3 ~ 17.0. Its flowers had a light yellow. It took about 44 ~ 50 days to flower, and flowered for 22~25 days. The dry weight of yellow mustard was $2.27{\sim}3.60tonha^{-1}$ with highest in sandy loam and loam. Among the nutrients of yellow mustard, nitrogen(T-N) was $12.6{\sim}20.8gkg^{-1}$, and C/N ratio was 21.6~37.7. The nitrogen yield of yellow mustard was $35{\sim}62kgha^{-1}$. In conclusion, because of its flowering characteristics and dry weight, yellow mustard was considered appropriate for both green manure and landscape crop uses.

A new pot chrysanthemum cultivar 'Peace Angel' was bred by cross pollination between 'Peace Yellow' and 'Lompoc' at the Yesan Chrysanthemum Experiment Station. The cross was made in 2003 and 'Peace Angel' was finally selected in 2007 after investigating its characteristics from 2005 to 2007. It flowers in the middle of October under natural conditions in Korea climate, but year-round production is also possible by short day treatment in summer or lighting treatment in winter. Flower shape is anemone type with pink petals and a yellow green center. Flower diameter is about 5.6 cm and the number of flowers per stem is 23.0, respectively. When short day treatment is necessary for manipulation of flower formation, 7 weeks of short day treatment is enough for the production. The shelf life is 22.4 days in the autumn season.

The natural flowering time of 'Yellow Candy' is late October, but year-round flowering is possible by photoperiodic control. It has pompon flower type with yellow petals and yellowish red flower center. The growth of plant is very vigorous. The diameter of flower is 4.3 cm. Number of flowers per stem and petals per flower are 8 and 184, respectively. Days to flowering under the short day treatment is about 58.5 and its vase life is 18.5 days in autumn season. 'Yellow Candy' was applied as No. 2009-177 on Feb. 18, 2009 for variety protection and the plant variety protection rights have been registered as No. 3247 on August 3, 2010 at the Korea Seed and Variety Service.

Hamamelis japonica (Hamamelidaceae), widely known as Japanese witch hazel, is a deciduous flowering shrub that produces compact clumps of yellow or orange-red flowers with long and thin petals. As a part of our ongoing search for phenolic constituents from this plant, eleven phenolic constituents including six flavonol glycosides, a chalcone glycoside, two coumaroyl flavonol glycosides and two galloylated compounds were isolated from the flowers. Their structures were elucidated as methyl gallate (1), myricitrin (2), hyperoside (3), isoquercitrin (4), quercitrin (5), spiraeoside (6), kaempferol 4'-O-β-glucopyranoside (7), chalcononaringenin 2'-O-β-glucopyranoside (8), trans-tiliroside (9), cis-tiliroside (10), and pentagalloyl-O-β-D-glucose (11), respectively. These structures of the compounds were identified on the basis of spectroscopic studies including the on-line LCNMR-MS and conventional NMR techniques. Particularly, directly coupled LC-NMR-MS afforded sufficient structural information rapidly to identify three flavonol glycosides (2 - 4) with the same molecular weight in an extract of Hamamelis japonica flowers without laborious fractionation and purification step. Cytotoxic effects of all the isolated phenolic compounds were evaluated on HCT116 human colon cancer cells, and pentagalloyl-O-β-D-glucose (11) was found to be significantly potent in inhibiting cancer cell growth.

This experiment was conducted to develop a healthy tea by fumigation, low temperature drying, drying and instant immersion using flowers of Robinia pseudoacacia L. that bloom in May in all regions of Korea. The drying was drying after fumigation treatment, low temperature drying, drying and instant immersion. The color of the flowers, beverage color, the sugar content, and the taste of the beverage were measured after changing the weight of the flowers. The change in the weight of flower tea was 11% ~ 12.5% of the body weight. The change in the color of the flowers appeared to be the lightest brown in the treatment of drying, and the other treatment area became turbidity white. The color of the beverage was yellowish from the tea treated with drying and became pale yellow when fumigation, low temperature drying and instant immersion. Sugar content was highest at 2.9brix from the drying and 2.6-2.7brix at the other three treatments. The taste was the best in the drying treatment, and the instant taste dipped in the tastes.
