A new spray chrysanthemum (Dendranthema grandiflorum) cultivar "Green Witch" was developed from a cross between 'S04161' and 'S04109' by selection of seedlings and lines at the Flower Research Institute, Gyeongnam Agricultural Research and Extension Services (ARES) from 2004 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 "Green Witch" was October 19th, and year-round production was possible by day length treatment. Its capitulum was 3.2cm in diameter, and had 15.9 head per stem in autumn. Its ray floret was green central zone. To flower in the short day condition, for "Green Witch" was about 44 days in spring, and "Green Witch" showed the vase life of 25.3 days in autumn.

This study was conducted to examine the effects of wet storage solution, transport period and temperature on vase life and quality of cut flowers in standard chrysanthemum 'Jinba'. Immediately after transport, the fresh weight and flower diameter of cut flowers did not show a difference according to wet storage solutions regardless of the transport period, but as the transport period increased, the fresh weight and flower diameter increased. The flower bud stage at harvest was maintained due to the small changes in flower diameter, and the freshness of leaves was better when transported at 5℃ than at 25℃. When transported at 25℃, the longer the transport period, the lower the quality of cut flowers as some petals opened up and showed early flowering after transport. In preservative solutions, quality of cut flowers transported at 25℃ was lower than that at 5℃ due to fresh weight and diameter according to the longer transport period. The vase life of cut flowers was 1.0 day, 0.8 day, and 7.3 days longer when transported for 3, 5, and 7 days respectively at 5℃ than at 25℃. The quality of cut flowers was better due to increase in fresh weight and flower diameter, as well as vase life in wet storage solutions of ClO₂ and Chrysal OVB than in tap water, regardless of transport period and temperature. There was no difference in fresh weight and vase life between ClO₂ and Chrysal OVB, but flower diameter was greater in ClO₂ than in Chrysal OVB. Therefore, for long-term transport of cut standard chrysanthemum 'Jinba', wet storage transport in ClO₂ at 5℃ was found effective in maintaining the quality and vase life of cut flowers.

This study was conducted to investigate effects of nutrient solution pH control agent and foliar spray of ethephon on the reduction of stem inside-cavity and improvement of flower quality in chrysanthemum 'Baekma'. Changes of pH in nutrient solution as affected by the kind of pH control agent showed more settled pattern in the plot of KOH treatment than in others. Plant growth and development such as cut flower length, leaf numbers, cut flower weight and petal number were the greatest in the plot of KOH. However, the size and area of stem cavity was large in KOH rather than $KHCO_3$. As changes in the absorbing patterns of mineral elements as affected by nutrient solution pH control agent in closed system, contents of total nitrate, phosphorus, potassium and calcium by $KHCO_3$ was absorbed into the plant less than KOH, so that it remained a lot of mineral element residues rather than KOH in closed system. Plant growth as affected by the foliar spray of ethephon showed growth retardation effect in the plot of solution diluted to 1 : 500 and growth promotion effect in the plot of solution diluted to 1 : 1,000 or 1 : 2,000. The number of petals was the best in the plot of foliar spray of ethephon solution diluted to 1 : 1,000 before flowering at 45 days showing 331 petals compared to control showing 302 petals. The size and area of stem cavity as affected the foliar spray of ethephon was smaller 1 mm and 7%, respectively, in the plot of solution diluted to 1 : 2,000 before flowering at 30 days than in control. Therefore, treating pH stabilization using KOH after floral initiation stage with the foliar spray of ethephon solution diluted to 1 : 2,000 before flowering at 30 days would help to reduce stem cavity size and improve flower quality in hydroponically grown chrysanthemum 'Baekma'.

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.
