  • The ornamental industry encompasses cut flower, pot plant, turfgrass and nursery stock production and is an important part of the agricultural sector. As internationally traded commodities, cut flowers and plants are an integral part of the economy of a number of developing countries in South America, the Caribbean and Africa. Genetic modification (GM) is a tool with great potential to the ornamental horticulture industry. The rapid progress in our knowledge of plant molecular biology can accelerate the breeding ornamental plants using recombinant DNA technology techniques. Not only is there the possibility of creating new, novel products the driver of the industry but also the potential to develop varieties requiring less chemical and energy inputs. As an important non-food agricultural sector the use of genetically modified (GM) ornamental crops may also be ideal for the intensive farming necessary to generate pharmaceuticals and other useful products in GM plants. To date, there are only a few ornamental GM products in development and only one, a carnation genetically modified for flower colour, in the marketplace. International Flower Developments, a joint venture between Florigene Ltd. in Australia and Suntory Ltd. of Japan, developed the GM carnations. These flowers are currently on sale in USA, Japan and Australia. The research, development and commercialization of these products are summarized. The long term prospects for ornamental GM products, like food crops, will be determined by the regulatory environment, and the acceptance of GM products in the marketplace. These critical factors will be analysed in the context of the current legislative environment, and likely public and industry opinion towards ornamental genetically modified organisms (GMO's).

  • A new spray carnation cultivar 'Leo' was released by the National Institute of Horticultural and Herbal Science in 2003. A cross was made between spray cultivar 'Ballantyne' and 'West peachy' in 1999. After investigation of the characteristics four years (from 2001 to 2003), it was finally selected in 2003. 'Leo' is a spray cultivar with light yellow color for a cut flower. The main characteristics are multi branching, long vase life and early flowering habit than 'Diamond'(control). It has medium resistance to Fusarium wilt and 9 days vase life.

  • The present study was conducted to determine the effects of electron beam irradiation on the postharvest quality of cut flowers. Cut flowers were irradiated with electron beam at 100, 200, 400, 600, 800, 1,000, and 2,000 Gy with a 10 MeV linear electron beam accelerator to evaluate their irradiation tolerance. Postharvest quality was determined by monitoring fresh weight loss, flower longevity, flower diameter, flowering rate, visual quality of flowers and leaves, and chlorophyll content. Cut flowers showed a radiation-induced damage with increasing the irradiation dose. Flower longevity and fresh weight of cut flowers decreased when the irradiation dose was increased. Flower bud opening was also inhibited in a dose-dependent manner. The effective irradiation doses for 10% reduction of postharvest quality (ED10) values were 144.4, 451.6, and 841.2 Gy in the 'Medusa' lily, 'Montezuma' carnation, and 'Rosina White' eustoma, respectively. Although tolerance of cut flowers to electron beam irradiation vary according to species, cultivars, or maturity stage conditions, it is conceivable that 'Montezuma' carnation and 'Rosina White' eustoma could be tolerated and maintained overall postharvest quality up to 400 Gy, the generic irradiation dose approved by the Animal and Plant Health Inspection Service (APHIS) and the International Plant Protection Convention (IPPC) for postharvest phytosanitary treatments.

  • Today, the number of the elderly living alone without any family members is on a sharp rise, and those aged people living alone are making these social issues such as solitary death, depression and suicide more popular. In order to resolve the issues, some of the local governments have been supporting the elderly living alone in common houses that would be used by senior citizens only. This study became interested in this 'carnation house' which has been carried out targeting the elderly living alone in Gyeonggi-do, and selected elementary universal design factors that should be applied to general residential environments of the aged people and analyzed the factors. As a case study, this research investigated four carnation houses as research subjects and came up with these following ideas about how to make improvements. First, the study found out that all the entrances did not have raised letters and that UD has not been satisfactorily applied to both the thresholds and the effective widths, and that is considered something to be fixed. Second, in case of regular rooms and living rooms, none of the rooms failed to have safety doorknobs which should have been installed and plus, thresholds and stepped pulleys need to be removed, Third, it goes the same with the kitchens, and the thresholds should be eliminated while cabinets are secured. In addition, furniture that understands the elderly's measurements should be used. Fourth, in terms of restrooms, they should be designed to be spacious enough not to cause anyone in wheelchairs inconvenience, and the study suggests that the effective widths should be widened and that both the safety doorknobs and the emergency calls must be installed. Basically, after the test on the UD adaptability, the study concluded that the application rates in connection with the adaptability were low which led the study to assume that such result has been gained due to the lack of installation standards in relation to the common living facilities of the elderly. The study now argues that purposes of buildings should be first clarified and then, these detailed space planning guidelines that deal with general characteristics of the aged people should be established.

  • As the molecular breeding was progressed, many plant transformation techniques were attained for improving transformation accuracy and used to produce useful transgenic plants. Day by day, new varieties were developed so new transformation techniques required for these newly developed varieties. Carnation (Dianthus caryophyllus L.) is a popular and economically important ornamental plant, all over the world. Keeping this in view, we selected 18 varieties of D. caryophyllus L. commonly available in the market and did optimization of culture conditions for more efficient tissue culture and to get higher number of plants via micro-propagation. Four varieties namely Yellowdotcom, Jakarta, Belmonte, Polartessino etc. were selected for organ culture studies from single cell line. The optimum growth was recorded in the MS media supplied with sucrose 3%, NAA 1.0 mg/L and TDZ 1.0 mg/L. except Belmonte, in which, BA 1.0 mg/L was found to be the best combination, in place of TDZ, rest ingredients were same. The most efficient coagulating agent used to obtain higher number of plant from callus was phytagel 0.3%. The most effective explant for higher shoot formation was stem in which 80.2% shoot formation was recorded. It also reduced culture periods by 6 days.

  • This experiment was carried out to examine the effect of a silicate fertilizer on the growth and development of potted plants. Cutting of Kalanchoe blossfeldiana 'Kaluna' and 'Taos', and Dianthus caryophyllus L. 'Kazan' and 'Tula' were grown in 50 and 128-cell plug trays, respectively. Rooted cuttings transplanted to the mixture of a commercial medium and perlite (5:1, v/v) supplemented with a silicate fertilizer at 0, 40, 80, 120 or $160g{\cdot}L^{-1}$ medium was evaluated. A silicate fertilizer supplementation at $40g{\cdot}L^{-1}$ medium resulted in the greatest plant height, leaf thickness, and root fresh and dry weights in both kalanchoe and carnation. However, plant height was suppressed in the treatment of a silicate fertilizer supplementation at higher concentrations in both kalanchoe and carnation. According to the scanning electron microscope images of transversal sections of tissues of roots and leaves in kalanchoe and carnation, the treatment of a silicate fertilizer supplementation at $40g{\cdot}L^{-1}$ medium resulted in plants with more compact tissue than the control.

  • 카네이션에서 적심은 분지수를 늘려 종묘비를 절감하고 개화기를 조절하는데 많이 이용되고 있다. 적심횟수는 1회, 1.5회, 2회의 방법이 있으며 농가에서는 주로 1.5회를 이용하고 있다. 양액재배는 토경재배에 비해 생장속도가 빨라 개화가 빠른 것으로 일반적으로 알려져 있고 양액재배에 적합한 품종 역시 숙기가 빨라 2회 채화가 가능하거나 숙기가 늦은 품종, 절화장이 짧은 품종, 분지력이 좋은 품종이 유리한 것으로 알려지고 있다. (중략)

  • 카네이션 품종은 200여종의 다양한 원종을 이용하여 품종을 만들었기 때문에 품종별 생리도 아주 다르며 양액재배를 했을 때는 더욱 다른 품종별 생육반응을 나타낸다. 그러므로 품종별 생육반응을 검토하기 위해 국내외에서 많이 재배되고 있는 품종, 화색과 화형을 달리한 품종과 원예연구소에서 육성한 품종 및 계통을 시험재료로 하여 순환식 양액재배를 실시하였다. (중략)
