  • A new rose variety, was selected from the progenies of a cross between "Cosai" and "Tokimeky" in 2006 after evaluation trials for three years (2004-2006). "Waltz" was developed because of many petals and powdery mildew resistance. A standard type with large sized flower, "Waltz" shows in 11.0 cm flower diameter. "Waltz" produces 130 stems?m-2 in a year. It has red-white color flower and 49.6 petals per flower. The stem length of cut flower was long with 69.3 cm. Vase life of the variety could be as long as 9.6 days.

  • A new standard carnation Dianthus caryophyllus 'Pink Beryl' was bred from a cross of red standard cultivar 'Francesco' and purple standard cultivar 'Saturn' in 1996 at the National Institute of Horticultural & Herbal Science. After investigation of the characteristics for 4 years from 1997 to 2000 and registered to the official breeding variety of Rural Development Administration in 2000. 'Pink Beryl' is pink standard cultivar with round edge of petal for cut flower. It has medium resistance to Fusarium wilt. To avoid calyx splitting caused by high temperature, this cultivar is recommended to grow over $8^{\circ}C$ at night and under $25^{\circ}C$ at days during flower bud differentiation period.

  • This experiment was conducted to examine the treatment conditions for single-color dyeing using the variety 'Akito' which was selected based on the flower size, density, blooming shape, elegance, expression of the dying color. The optimal conditions of dyeing rose flower were pH 3.5 under the $20-25^{\circ}C$, in which the vase life showed 15 days as longest after dyeing. The most suitable flower stage for dyeing was identified as second or third stage at which three petals of flower are opened. $10g{\cdot}L^{-1}$ concentration of dyeing solution with $2mL{\cdot}L^{-1}$ treatment of spreader for rose dyeing gave the best color performance.

  • Typical rose flowers, 'Red Corvette (red)', 'Nobless (pink)', 'Golden Metal (yellow)', and 'Rose Yumi (white)', were used as experimental materials to examine flower color changes as affected by pressing method and light treatment for four weeks and eight weeks by 2,000 lux fluorescent light at a 16 hours daylength. Pressing materials in silicagel mat resulted in the least change after pressing and light treatment for all kinds. On the contrary, an electric pressing device caused color to change to brown. Flower colors deteriorated the most by an electric pressing device made in Korea for pink rose; an electric pressing device made in Japan for white rose; and paper sheet made in Korea for red rose. The sequence of degree in severity of color change after pressing was pink, yellow, and white roses. Light treatment brought about the most extreme color change in yellow 'Nobless' rose, while other three cultivars were rather stable in change of color.

  • This study was carried out to find morphological characters of flower and its distribution in mixed population of Paeonia lactiflora Pallas. In distribution of flowering periods, early, medium, and late matured type were 18%, 56%, and 26%, respectively. Flowering duration was less than eight days in 9% of flowers. In next 9 to 11 days, 12 to 14 days and more than 15 days showed, 50%, 37% and 4% respectively. For flower sizes, small size below 9cm diameter were 11%, medium size between 9 to 13cm diameter and large size above 13cm diameter were 65% and 24%, respectively. Among six kinds of flower colors - red, red pink, pink, light pink, pale yellow and white, pink color flowers was dominant, showed 56%. In flower types, single flower was 76%, and anemone, crown, bomb and japanese types were also present. Flower stem diameter were positively correlated with flowering duration, flower size and number of stamens, and negatively correlated with number of stamens and pistils, number of pistils and petals.

  • This experiment was conducted to characterize the inheritance of petal color, flower-eye color, flower shape, leaf variegation pattern, and leaf-end shape in Cyclamen persicum. The segregation of $F_2$ and backcross populations from crosses between inbred lines was tested for Mendelian inheritance mode. From four different combinations of crosses, it was found that the petal color was controlled by a single incomplete dominant gene. The other characters, flower-eye color, flower shape, leaf variegation pattern and leaf-end shape were confirmed to be controlled by single complete dominant genes.

  • A new cultivars Dendranthema grandiflourm 'Dream Moon' was developed at Gyeonggi-do Agricultural Research and Extension Services (GARES), Korea in 2008. The cultivar 'Dream Moon' was derived from a cross between 'Patra', a spray cultivar with yellow single type, and 'Sei-rosa', a spray cultivar with pink single type in 2005. The cultivar has single type flowers with pink petals. Trial evaluation was conducted from 2006 to 2008 for a shading cultivation in summer and a retarding cultivation in spring. The flowering time of 'Dream Moon' is late October, and year-round flowering is possible by shade or light treatment. The diameter of flower is 56.0 mm. Numbers of flowers per stem and petals per flower are 16.4 and 24.6, respectively. After investing of specific characters from 2006 to 2008, it was finally selected and named 'Dream Moon'. It has resistance to white rust and the vase life is about 20.7days in autumn season.

  • The antidepressant effects of Cirsium japonicum was revealed in previous studies using open field test and forced swimming test. The contents of total flavonoids and apigenin of Cirsium japonicum were analyzed and sensory evaluation of Cirsium japonicum tea was performed in order to develop Cirsium japonicum tea as an antidepressant. Among the different plant parts of Cirsium japonicum, leaves had the highest level of total flavonoids and apigenin contents and were followed by flowers and stems. Drying method affected total flavonoids and apigenin content of Cirsium japonicum, but regular pattern was not revealed. In sensory evaluation, overall acceptance of Cirsium japonicum flower-leaf mix tea was higher than those of Cirsium japonicum leaf tea. Also purchase intention of Cirsium japonicum flower-leaf mix tea was higher than those of Cirsium japonicum leaf tea.

  • Two individuals ($sp_1$, $sp_2$) of purple and one individual ($sd_1$) of red hearted flower were selected from 18 years old Hibiscus syriacus trees obtained from the seeds treated with colchicine, and their morphological and physiological characteristics were investigated and following results were obtained. 1. The somatic chromosome number of the selected individuals, $sp_1$, $sp_2$, and $sd_1$ were 2n=160, while that of the check tree was 2n=80, indicating that the selected individuals, $sp_1$, $sp_2$ and $sd_1$ were tetraploid. 2. Peroxidase isoenzyme bands of high activity in selected individuals, $sp_1$, $sd_1$ and check tree were mostly in cathode, fixed band was f and v bands, and frequency of each band and their activity were not different between selected individuals, $sp_1$ and $sd_1$ and check tree. 3. The flowers of $sp_1$ individual were large in size and more dark purple than check tree's. The flowers of $sp_2$ individual were not increased in size, but they were dark purple and red heart at the base of the petal was expanded to 2/3 of the petal length. The flower of $sd_1$ individual was also large and some of the red lines from the petal base were extended to 2/3 of the petal length, which was much longer than those of the check tree. 4. Thickess of leaves, length of guard cells, diameter of pollens, wood fiber lengths and woody fiber widths were all increased in $sp_1$, $sp_2$ and $sd_1$ as compared to those of the check tree. 5. Survival percentage of cuttings was 80% with $sp_1$ and 36% with $sd_1$, and their growth performance were inferior to control in their second growing season.
