A new spary chrysanthemum(Dendranthema grandiflorum) cultivar 'Noble Wine' was developed from a cross between 'SL03-01' and 'Artist Pink' by selection of seedlings and lines at the Flower Research Institute, Gyeongnam Agricultural Research and Extention Services(ARES) from 2003 to 2007. Its characteristics were investigated three times from 2005 to 2007 under condition of forcing culture in spring and retarding culture in autumn. The natural flowering time of 'Noble Wine' was October 26th, and yearround production was possible by day length treatment. Its capitulum was 5.4 cm in diameter, and had 21.6 ray florets and 28.5 head per stem in autumn. Its ray floret was red-purple with green central zone. 'Noble Wine' was about 45 days in spring, and 'Noble Wine' showed the vase life of 21.3 days in autumn. This cultivar was registered for a commercialization in 2007.

The purpose of this study was to investigate the effects of ethephon, paclobutrazol, and uniconazole on the flowering of potted Yarrow (Archillea millefolium). Each plant growth regulator was sprayed two times before stem elongation period of yarrow. The tallest was 45.7 cm at $1000mg{\cdot}L^{-1}$ ethephon and the shortest was 11.1 cm at 20 uniconazole. Uniconazole delayed flowering and decreased the number of flowers. Both uniconazole at 20 ppm and paclobutrazol at 200 ppm decreased the number of florets to 90.0% and 43.6% of control, respectively. In ethephon, number of florets was increased 34.1% compared with control. In addition, ethephon and paclobutrazol increased the number of mean auxillaly flowers to 28.6% and 23.5% of control, respectively. On the other hand, uniconazole decrease the number of auxillary flowers to 55.3%. Thus, paclobutrazol was recommended as a suitable plant growth regulator for yarrow pot plant production.

The natural flowering time of 'Moulin Rouge' was October 24th, and year-round production was possible by day length treatment. Its capitulum was 5.3 cm in diameter, and had 22.9 ray florets and 12.2 head per stem in autumn. Its ray floret was bi-color(yellow/orange) with green central zone. 'Moulin Rouge' was about 55 days to flower in spring, and showed the vase life of 21.7 days in autumn. This cultivar was registered for a commercialization in 2007.

A new gerbera cultivar 'Lovely Moon' was released by the National Institute of Horticultural & Herbal Science (NIHHS) in 2008. A cross was made between 'Sever Line' and 'Angel' with yellow and semi-double flower in 2005. After investigation of the characteristics for four years (from 2005 to 2008), it was selected specially for the use of cut flowers. 'Lovely Moon' is a vigorous cultivar with yellow (RHS Y13B), yellow green center and semi-double flower. The average flower diameter is 12.7 cm, a large flower. And inner ray floret and disc diameter are 6.10 cm and 2.80 cm, respectively. It produces a large number of flowers with continuous supply of flowers and has a long peduncle height. We believe that 'Lovely Moon' has a great potential for expanding cultivated area of domestic gerbera cultivars and increasing farm income.

A new spary chrysanthemum(Dendranthema grandiflorum) cultivar 'Serapina' was developed from a cross between 'Relanse' and 'Yen' by selection of seedlings and lines at the Flower Research Institute, Gyeongnam Agricultural Research and Extention Services(ARES) from 2002 to 2006. Its characteristics were investigated three times from 2004 to 2006 under condition of forcing culture in spring and retarding culture in autumn. The natural flowering time of 'Serapina' was October 23th, and year-round production was possible by day length treatment. Its capitulum was 2.8cm in diameter, and had 43.4 ray florets and 28.9 head per stem in autumn. Its ray floret was yellow with green central zone.

In order to investigate the changes of free amino acids during the differentiation and development of young spike in naked barley, a typical spring grain, Wanju, and two winter grains, Sedohadaka and Nonsankwa No. 1-6 differing in their spring habits, were analyzed at different growth stages by thin layer chromatography. In all the varieties 22 ninhydrin positive components were detected at the sowing time of March 5 and 20 components in the sowing plots of March 30. In case of the latter plot, β-alanine was identified only in both Wanju and Sedohadaka, whereas pipecolic acid was detected only in Nonsankwa No. 1-6. Particularly, it is interesting that β-alanine was observed only in the case showing the normal heading independent of the varieties and sowing times. Whether these components are directly related to the physiology of spring habits in barley or not is also a question to be answered. Of the major amino acids, alanine and γ-aminobutyric acid were always detected in appreciably large spots, and serine, leucine, aspartic acid, valine and asparagine were somewhat larger. In the plot of march 30, glutamic acid was also detected in very large spot in both Wanju and Sedohadaka at the stage of spikelet differentiation and in Nonsankwa No. 1-6 at the stage of bract differentiation. Histidine, which showed the only qualitative difference among the varieties during seed germination, cannot be observed at all. Proline observed considerably large spot during seed germination was always detected but very small except that it was observed in large spot at the stage of floret differentiation in Nonsankwa No. 1-6 in the plot of March 5.

A new gerbera cultivar 'Sunny Lemon' was released by the National Institute of Horticultural and Herbal Science (NIHHS) in 2009. A cross was made between 'Pavlov' and 'Patrick' with pink and semi-double in 2006. After investigation of the characteristics for four years (from 2006 to 2009), it was selected for the use of cut flower. 'Sunny Lemon' is a vigorous cultivar with yellow flower color (RHS Y9C), brown center and semi-double. The average flower diameter is 11.0 cm. And inner ray floret and disc diameter are 7.63 cm and 2.59 cm, respectively. Days to first blooming are 84.5, approximately 2 weeks earlier than the standard cultivar. It produces a large yield with continuous supply of cut flowers and has adequate peduncle height. We believe that 'Sunny Lemon' has a great potential for expanding cultivated area of domestic gerbera cultivars and increasing farmers' income.

A new gerbera cultivar 'Whiteny' was released by the National Institute of Horticultural & Herbal Science in 2009. A cross was made between 'Wonder King' with white semi-double and 'Ever Green' with pale greenish white and semi-double in 2007. After evaluation of the characteristics for four years (from 2007 to 2010), it was selected specially for the use of cut flower. The 'Whiteny' cultivar has pure white color (RHS W155D) with black disc center and semi-double flower. The average flower diameter is 11.5 cm, large-sized flower. And inner ray floret and disc diameter are 7.8 cm and 2.2 cm, respectively. It has a long peduncle height, 52.2 cm, and longer vase life, 12.1 days. And it is also adaptable to the local cultural environment of Korea. It is expected that if the 'Whiteny' cultivar is planted, the royalty paid to foreign varieties can be saved. And the local growers will also be benefitted since the cost of cultivars will be lower than the imported ones.
