Experiments were conducted to evaluate quality and vase life of cut rose 'Rote Rose' cultivated in soil or hydroponically in rockwool. Rose flower stems harvested in commercial greenhouses in Kimhae on May 27 and June 14, 1998 were transported for about two hours to a laboratory and recut in water to an uniform stem length of 45cm. The rose flowers harvested on the same day were displayed at a density of $10cm{\times}10cm$ and were subjected to the same environmental conditions in a growth chamber. The stems were put in four different preservative solutions, 0.5% Chrysal RVB, BS (2% sucrose+200ppm 8HQS+0.3% Chrysal RVB), Sonk1 (BS+0.1mM ethionine), and double distilled $H_2O$. Flower stems harvested on May 27 were displayed at $18{\pm}1^{\circ}C$, RH 60-70%, and light intensity of 220lux provided by fluorescent lamps for $16h{\cdot}d^{-1}$. Flower stems harvested on June 14 were displayed at $25{\pm}1^{\circ}C$, RH 70-80%, and light intensity of 220lux provided by fluorescent lamps for $16h{\cdot}d^{-1}$. Fresh weight and flower diameter were affected by cultivation method, and were greater in hydroponically-grown roses than in soil-grown roses. Among the preservative solutions, BS and Sonk1 were superior to Chrysal RVB in terms of prolonging vase life. Vase life extension in Chrysal RVB, BS and Sonk1 over the control was about one day in both display temperatures. At $18^{\circ}C$ vase life was maintained for three to four additional days as compared to that at $25^{\circ}C$.

This study was carried out to investigate effects of stock plant management and foliar spray of GA on the flower quality in hydroponically grown chrysanthemum 'Shinma'. In the growth and development as affected by stock plant management, cut flower length, petal number and cut flower weight were the best in the plot of long day and chilling treatment showed 114 cm, 298 and 102 g, respectively. Chlorophyll content(SPAD-value) was the highest in the plot of foliar spray of diluted Molbia(1 : 500). Flower quality according to concentration and spray time of gibberellin showed a different pattern. Cut flower length was the longest in the plot of solution diluted to 1 : 1,000 spraying before flowering at 60 days, petal number was the most in 1 : 500 at 60 days, and cut flower weight was the heaviest in 1 : 2,000 at 60 days, respectively. However, peduncle length was tended to be elongated with foliar spray of gibberellin solution diluted to 1 : 500 or 1 : 1,000 before flowering at 45 days.

Phalaenopsis (P.) has various species, and some of them have strong fragrance. There are fragrant species such as P. bellina, P. violacea, P. schilleriana and used in breeding program for fragrant Phalaenopsis. This study was performed for establishment of fragrance analysis system using GC-MS and electronic nose in eight P. resources. We analyzed fragrant compound using the tissue of sepal, petal, column, and lip of P. '3010'. The percentage of the major compound was high in the petal and lip tissues. The main compound emitted from P. bellina was linalool (21.21%). It was possible that fragrance pattern could be analyzed among the resources using the electronic nose. Discriminant function analysis (DFA) was more useful than the principal component analysis (PCA) in statistics program. We utilized GC-MS method for the major compounds of flower from our breeding materials. This study would be useful to the fragrant analysis system for the fragrant orchid breeding in the future.

Edible flowers are harvested at the full bloom stage and distributed without floral stems, which makes the flower quality deteriorated quickly. Thereby, this study was carried out for selection of effective storage film at room temperature during the distribution of edible flowers. Edible flowers, snapdragon (Antirrhinum majus), pot-marigold (Calendula officinalis), sweet violet (Viola odorata), clove pink (Dianthus caryophyllus), wild pansy (Viola tricolor), nasturtium (Tropaeolum majus) were used to select the effective storage film at room temperature during the distribution, polyethylene (PE) film (0.03 mm), polypropylene (PP) film (0.03 mm). PP (LF10) film packing was very effective for longer shelf life for sweet violet, clove pink, and wild pansy. But, there were little different for pot-marigold and nasturtium. Wilting at sweet violet, clove pink, and wild pansy, and petal-soft rot and color break at nasturtium were appeared. Browning and rot were appeared to snapdragon.

A new standard rose cultivar 'Snow Ball' was bred by the cross between the red standard cultivar 'Red Sandra' and the scarlet standard cultivar 'Baroness' at the National Institute of Horticultural and Herbal Science, in Suwon. The cross was made in 1998 and 'Snow Ball' was finally selected in 2003 after investigating the characteristics for three years from 2001 to 2003. 'Snow Ball', a white standard cultivar grows vigorously and has good flower shape. The major characteristics of this cultivar are $90.3stems/m^2/year$ in yield, 57.8 cm in length of cut flower, 6.1 cm in flower diameter, 85.7 in petal number, and 15.0 days in vase life. This cultivar can be propagated by both cutting and grafting. The consumer's preference of this cultivar is relatively higher than that of control cultivar, 'Tineke'.

An unrecorded species in Korean flora, Hydrangea luteovenosa Koidz. (Hydrangeaceae) was collected from parasitic cone, Seongneol-orom region of Mt. Halla in Prov. Jeju-do. This species is readily distinguishable from H serrata (Thunb.) Ser. and H. petiolaris Siebold & Zucc. in Korea by habit, length and width of leaves, length of petiole, morphology of petals and leaf margins, position of ovary, number of stamens and secondary veins.

Mixing performance between fuel and oxidizer is a significant parameter of combustion efficiency and stability in an air-turbo ramjet combustor. Two types of petal mixer were experimented to research the mixing performance. Mixing performance and fuel distribution images were obtained for petal mixers. Planar laser-induced fluorescence(PLIF) was used to obtain 2-D fuel distribution. The obtained images were processed in order to make use of the image information to a quantitative level. The results of analyzing the fluorescence images could be useful to find better mixing performance between mixers.

Neottia japonica (Blume) Szlach. (Orchidaceae), previously known to be native in southern part of Japan and Taiwan, was found in Seogwipo-si, Jeju-do, Korea. This species is distinguished from the related taxa of Neottia pinetorum (Lindle.) Szlach and N. nipponica (Makino) Szlach. by smaller plant, lip with T-shaped lamella and auricles embracing column, and flowering in the spring. The local name was given as "A-gi-ssangnip-nan-cho" based on the cuter and smaller plant than N. pinetorum. The description and illustrations of the species on morphological characters, voucher specimens, and photograph at the habitat are provided.

In the present study, we investigated the effects of artificial removal of corolla and calyx lobes from open flowers on fruit development and fruit quality of strawberry (Fragaria ${\times}$ ananassa Duch.). Removing the corolla had no significant effect on fruit weight, hardness, length, and diameter, Hunter L, a, b values, sugar content and acidity. However, removing the calyx lobes significantly inhibited longitudinal and transverse growth of the fruits, resulting in diminished fruit size. In addition, merchantable fruit quality significantly decreased upon removing the calyx lobes, and this tendency was increased as more calyx lobes were removed. Nonetheless, removal of the calyx lobes had no effects on fruit color, sugar content, or acidity, similar to the effect of corolla removal.

Culture conditions for high frequency embryogenesis and plant regeneration in anther cultures of various F$_1$ hybrid and homozygous lines of pepper (Capsicum annuum L.) are described. Anthers pigmented less than halfway from the distal end were dissected from the flower bud in which petals elongated 2 mm higher than the receptacle. They were placed on Dumas medium supplemented with 0.1 mg/L 2,4-D and 0.1 mg/L kinetin. After four weeks of culture, embryos began to appear on anthers. After eight weeks of culture, frequencies of embryo formation reached up to 58.3%. Upon transfer to MS basal medium, greater than 95% of embryos developed into plantlets.
