  • A new gerbera cultivar 'Noble Pink' was released by the National Institute of Horticultural & Herbal Science (NIHHS) in 2009. A cross was made between 'Himalaya' with white and semi-double and 'Vital' with pastel cream and single in 2006. After investigation of the characteristics for four years (from 2006 to 2009), it was selected specially for the use of cut flower. 'Noble Pink' is a vigorous cultivar with pastel pink flower color (RHS R48B), brilliant green disc floret and semi-double. The average flower diameter is 11.8 cm, large flower. And inner ray floret and disc diameter are 4.77 cm and 2.17 cm, respectively. It produces a large yield with continuous supply of cut flowers and has adequate peduncle height. We believe that 'Noble Pink' has a great potential for expanding cultivated area of domestic gerbera cultivars and increasing farmers-income.

  • This research was carried out for revealing the co-relationships between insect-pollinators and the plant species of Labiatae and Umbelliferae, insects visiting in flower and the flowers in Korea, were studied from April 2010 to August 2012. The sum of flower visiting degrees in Labiatae are shown 21 in Hymenoptera, 16 in Lepidoptera, and the lowest 1 in Diptera and Coleoptera, respectively. The sum of flower visiting degrees in Umbelliferae are shown 27 in Diptera, 24 in Hymenoptera, 21 in Coleoptera, and 13 in Lepidoptera, respectively. 17 pollinator species visited the flower of Angelica gigas, next 15 pollinator species did the flower of Agastache rugosa, 13 pollinator species did the flower of Prunella vulgaris var. lilacina. 13 pollinator species foraged on the flower of Peucedanum terebinthaceum. and then 11 pollinator species on the flower of Angelica dahurica. Only 1 pollinator species visited the flower of Clinopodium chinense var. grandiflora and Isodon excisus. Pollinators of Coleoptera and Diptera visit more frequently to the flowers of Umbelliferae than those of Labiatae. Pollinators of Lepidoptera and Diptera visit more frequently white flower than purple one. This study found out that mutualistic relations between plants and insect pollinators in Korea.

  • The study was conducted in order to systematize specialization of flower decoration. The results of this study are summarized as follows. The research of image adjectives were analyzed into a total of 4 factors, which are texture, color, period, decoration. With regard to texture, the flower with the highest texture of 2.00 was white Zantedeschia aethiopica and that with the lowest texture of -1.90 was Leucospermum cordifolium. In regard of color, the flower with the highest color of 1.70 was Rosa 'Judy' and that with the lowest color of -2.40 was Gypsophila. With regard to period, the flower with the highest period of 2.00 was Gomphrena globosa and that of the lowest of -3.00 was Leucospermum cordifolium. In decoration, the flower with the highest decoration of 2.50 was Agapanthus 'Intermedia' and that with the lowest decoration of -2.00 was Heliconia bihai 'Lobster'. As for correlation among the factors, color and period were in a correlation with each other. It shows that color and period are the most important factors in flower decoration. In result of conjoint analysis, importance was high in order of color, texture, decoration and period. This suggests that consumers overemphasize color and texture in flower decoration and may fail to notice the importance of period.

'Vanilla perfume', an orange-colored (RHS Orange Group 27C) standard rose cultivar with 48 petals, was used as the female plant. 'Marcia', a white-colored (RHS Green white Group 157B) standard rose cultivar with 96 petals was used as the male parent. A cross was made in 2009 and seedlings were produced. Selections were made between 2010 and 2013, and a plant with good cut flower traits was finally selected and named 'To Dios'. 'To Dios' is a standard rose with large flowers of 11.2 cm in diameter and 128 peach-colored (RHS Red Group 36B) petals per flower. Vase life of this cultivar is up to 15 days. It takes 47 days from pruning to blooming and cut flower productivity is approximately $160stems/m^2$ per year. 'To Dios' was registered as a new cultivar No. 4875 with the Korea Seed & Variety Service on March 19, 2014.

  • This study was conducted to provide exportation strategy by surveying on preference of Japanese consumers on cut chrysanthemum exported. The survey was conducted two times by a local survey company in Japan, and the surveys were conducted largely on chrysanthemums for casual flowers and the altar. After departmentalizing Japanese consumers per groups the result were analyzed through conjoint and cluster methods, flower colors and shape were used relatively higher rate for selection criteria of flowers in every group in the case of casual flowers. Group 1 comprised of 60 year-old housewives who reside in a small city with high school diploma and annual income less than 300 million yen, and group 2 of 40 year-old housewives who are small city residents with high school diplomas and annual income of 300 million yen show higher rate of use in flower shape than colors. Another group 3 whose members are 50 year-old housewives, small city residents with high school diplomas and annual income of 600 million yen showed higher rate of use colors than the shape for selection criteria of flowers. The consumption characteristics according to the ages of the consumers showed a pronounced tendency. The 40-50 year-old housewives preferred single flowers packed with other flowers, and the 60 year-old housewives double flowers packed with only chrysanthemums. In flower color, the 50-60 year-old housewives preferred white and yellow flowers, and the 40 year-old housewives pink and yellow flowers. Therefore, there are needs for development strategy of new products considering the consumption characteristics of flower shape and color according to the ages of consumer. After analyzing the chrysanthemums for altar by departmentalization of Japanese consumers, every group showed relative higher rate of use for flower shape for selection criteria of flowers. According to the analysis on the consumption characteristics, group 1 which is comprised of 30-40 year-old housewives who reside in small city with high school diplomas and income less than 300 million yen, and the group 2 of 20 year-old housewives who reside in small city with college diplomas and annual income less than 300 million yen. They are very sensitive to the price of the products while the group 3 of 50 year-old housewives who reside in small city with high school diplomas and annual income less than 300 million yen are insensitive to the price. The 30-50 year-old housewives preferred white and pink flowers, and the 20 year-old housewives yellow and pink flowers. In flower shape, the 50 year-old housewives preferred anemone shape, the 30-40 year-old housewives double shape, and the 20 year-old housewives pompon shapes. Therefore, the white, double flowers for the 30-40 year-old housewives and the yellow, pompon flowers for the 20 year-old housewives are needed to be created at the lowest cost, while the white, anemone flowers are needed to created at higher cost with high quality. In light of these results, it is considered that we should understand the types of purchasing products through consumption characteristics of Japanese consumers. Also we should plan, create market-oriented and consumer-oriented products, and should export them in order to expand more exportation.

  • Bulbs of Lilium Oriental hybrids cv. 'Casablanca' and 'Marco Polo' were grown in a plastic house in alpine area of Pyongchang Kangwondo. Saw-dust, black film, reflective film, transparent film, and white/black double film were used as mulching materials to ascertain the growth of foliage, the quality of flower, and the size of bulbs. Foliage weights of both lilies were higher when lilies were grown with mulching materials than control. There were no differences of bulb weight among the control and mulching treatments, except delayed bulb growth in black film and white/black double film. Mulching cultivation with saw-dust and reflective film stimulated foliage growth, root growth and bulb production, but black film delayed the growth and development. Transparent and white/black double films showed no effects on foliage growth and bulb development than the control. As mulching materials tended to delay lily growth, including foliage and bulb, an extension of growing term might be better to produce high quality lilies than common cultivation in alpine area.
