  • A new bright yellow gerbera (Gerbera hybrida Hort.), 'Sunmyo' was bred from a cross between red medium-gerbera 'Beauty' and yellow gerbera 'Tamara' in 2001. Characteristics trials were conducted three times from 2004 to 2006. Bred cultivar 'Sunmyo' showed bright yellow color (YG12B), black center, semi-double type, and middle size flower with stable flower shape. The average yield of 'Sunmyo' increased up to 37% (70.0 stems per year) as compared to control cultivar 'Biro' (51.0 stems per year). The vase life is 7.5 days. The survival rate is 85.0%, and days to first flowering are 95 in the plastic house passing the winter season.

  • A new spray chrysanthemum 'Pink Berry' was released by National Institute of Horticultural and Herbal Science (NIHHS), Rural Development Administration (RDA), Korea in 2007. A cross was made in 2004 between 'Lineker Salmon', a spray cultivar with salmon petals, and 'Baeksokuk', a spray cultivar with white petals. Trials were conducted from 2005 to 2007 for evaluation and selection of this cultivar, including shade cultivation in summer and retarding cultivation in autumn. The natural flowering time of 'Pink Berry' is late October, but year-round flowering is possible by photo-periodic control. The cultivar has single type flowers with pink petals and a green flower center. It shows long vase life of 22 days and resistance to white rust. The diameter of flower is 52.0 mm. The numbers of flowers per stem and petals per flower are 15.5 and 29.5, respectively. Days to flowering under the short day treatment is about 56 in autumn seasons.

Effects of Daminozide Spray and Floral Preservatives on Longevity and Ethylene Production of Cut Lily (Lilium longiflorum Thunb.) (수확전(收穫前) Daminozide의 살포(撒布)와 수확후(收穫後) 절화보존제(切花保存劑)의 처리(處理)가 절화백합(切花百合)의 수명(壽命)과 Ethylene발생(發生)에 미치는 영향(影響))

  • This study was conducted to clarify the effects of daminozide (butanedioic acid mono-(2,2 - dimethylhydrazide)) sprayed 2 days be fore harvest and floral preservative solutions on longevity, quality and ethylene production of 'Georgia' cut lily for prolonging vase life and improving quality of cut lily flowers. And also the relation between ethylene production and flower senescence of cut lily was studied. 1. Lilies held in silver nitrate ($AgNO_3$) at 25 and 50 ppm were increased in solution uptake, fresh weight, and flower longevity. The solution of 2.5% sucrose+50 ppm $AgNO_3$+200 ppm aluminum sulfate+10 ppm 6-benzylamino purine prolonged vase life and improved quality of cut lily flowers. 2. Lilies sprayed with 500 ppm daminozide 2 days be fore harvest and then held in the preservative solution (5% sucrose+50 ppm $AgNO_3$+150ppm 8-hydroxyquinoline) after harvest were significantly increased in fresh weight and vase life as compared with non-sprayed (control) flowers. 3. Ethylene production from cut lily was increased by ethephon ((2-chloroethyl) phosphonic acid) treatment. The flowers producing a lot of ethylene, however, were senesced slowly instead of rapid wilting. 4. The preservative solution markedly reduced ethylene production of cut lily but prolonged vase life for only a few days. 5. These results suggest that ethylene be one of the most important factors promoting flower senescence of cut lily, but it be very difficult to prolong vase life remarkably by only inhibition of ethylene production in cut lily.
