A rose cultivar "Haedoji" developed at the Jeollanamdo Agricultural Research and Extention Services (JARES) is a standard type with deep Red flower. From 2000, two cultivars 'Vital' and 'Cardinal' were examined for horticultural characteristics and were included in cross-combination in 2003. Cultivar 'Vital', a vigorous standard type, first preference with red flower, was used as a mother plant and cultivar 'Cardinal', a red flower standard type with light color, was used as a pollen-donor plant. seventeen six breeding lines were selected in 2004 based on flower shape, flower color and abundance of petal numbers on the first selection. two breeding lines were selected in 2004 based on powderly mildew and vigor on the second selection. For three years, from 2005 till 2007, one breeding lines were selected and examined for their productivity, and then cultivar "Haedoji" was developed because of distinctive characters such as light red color flower, upright stem, long vase-life and Resistance to the Powderly Mildew. A standard type with intermediate sized flower, cultivar "Haedoji" shows in average 9.2 cm flower diameter, 62.0 cm flower stem length, and 9.5 days vase-life. The average productivity for three years was $167.3stems{\cdot}m^{-2}$ per year and increased 2% compare to cultivar 'Tiamo' with $163.9stems{\cdot}m^{-2}$ per year.

Experiments were conducted to determine the effects of plant growth regulators on in vitro flowering and micropropagation of Gentiana scabra Bunge which had been used the cut flower, pot flower ornamental and medicinal plants. Flower bud formation was affected by GA$_{3}$ and kinetin. The optimum concentrations for flower bud formation was observed at 0.5 mg/l kinetin and GA$_{3}$ , while kinetin was favorable. More flowerings result from the interaction of GA$_{3}$ and kinetin at in a combination of 0.1 mg/l kinetin + o.1 mg/l GA$_{3}$, but the optimum concentration of GA$_{3}$ and kinetin was decreased. All concentrations of kinetin with 0.1 mg/l GA$_{3}$ or O mg/l GA$_{3}$ + 0.5 mg/l kientin reduced t (weeks needed for 50% plantlets). The plantlet growth was affected by GA$_{3}$ and kinetin during plantlet culture. More lateral shots and better shoot length per plantlet were obtained as GA$_{3}$ and kinetin concentration were increased up to 1.0 mg/l. The number of per plantlet was greater increased in MS medium containing GA$_{3}$ than kinetin. Interaction was exhibited at lower concentration with 0.5mg/l GA$_{3}$ and kinetin, but not in higher concentration with 1.0 mg/l GA$_{3}$ and kinetin. Higher pod diameter increased seed germination, while lower pod diameter was obtained from abnormal plantlet. MA medium containing 0.5 mg/l GA$_{3}$ significantly increased germination without regard to pod diameter.

This study was performed to identify the effect of fertilizer application and planting method on growth and yield of 'Seolhyang' strawberry during seedling raising. According to the concentration of fertilizer applied, the height of daughter plants was the highest at an EC of $0.8dS{\cdot}m^{-1}$. Leaf number and crown diameter were greatest at an EC of $0.6-0.8dS{\cdot}m^{-1}$. In the first measurement, root number was highest in non-fertilizer application, while root weight was heaviest in non-fertilizer application and EC $0.4dS{\cdot}m^{-1}$. The higher the concentration of fertilizer applied as culture media, the lower the growth rate. Thirty days after planting on the main field, plant height and number of new leaf were highest at an EC of $0.8dS{\cdot}m^{-1}$. However, no significant difference was found in leaf length and width and chlorophyll content according to fertilizer application. Marketable yield of 25 g or higher was greatest in EC $0.6dS{\cdot}m^{-1}$. In contrast, no significance was found in total marketable yield at an EC of $0.4-0.8dS{\cdot}m^{-1}$. Aconsistent pattern was exhibited in the growth of 1-5 harvesting flower clusters according to planting method. The length of leaf and flower cluster was short and chlorophyll content was low, when bed soil was removed 100% in harvesting of the first flower cluster. In all treatment, leaf length was shortened until harvesting of the second and third flower cluster, but rapidly lengthened in harvesting of the third and fourth flower clusters. Moreover, the length of flower cluster had a increasing tendency from harvesting of the third flower cluster. However, chlorophyll content was reduced continuously until harvesting of the fifth flower cluster, and was lowest in harvesting of the fourth flower cluster without removal of bed soil. Total yield was greatest in treatment of crown removal in bed soil between November and May. Late marketable yield between March and May was highest in treatment of 100% bed soil removal, followed by treatment of crown removal. Marketable yield of 25 g or higher was greatest in treatment of crown removal between December and February, while greatest in treatment of 100% bed soil removal between March and May.

An investigation was conducted to elucidate the effect of sucrose, germicides and abscisic acid (ABA) in the preservatives on postharvest quality, such as fresh weight, solution uptake, vase life, diameter and thickness of flower, and chlorolhyll of leaf in cut chrysanthemum 'Kyoungsubang`. Fresh weight of cut chrysanthemum was highest in 250mg/L aluminum sulfate [{TEX}$Al_{2}(SO_{4})_{3}${/TEX}]+3% sucrose and 250 mg/L 8-hydroxyquinoline sulfate (8-HQS)+ 3% sucrose. Addition of sucrose and germicides inhibited microorganisms growth in solution, and apparently promoted solution uptake. The increased fresh weight seems to attribute to the elevated uptake. Germicide 8-HQS was more effective than {TEX}$Al_{2}(SO_{4})_{3}${/TEX} in the aspect of solution uptake and fresh weight. Treatment of 250 mg/L 8-HQS +3% sucrose showed the longest vase life (24.67±2.52 days) and the lowest rate of leaf chlorosis (or senescence). Addition of {TEX}$Al_{2}(SO_{4})_{3}${/TEX} and sucrose accelerated leaf chlorosis and increased diameter of flower, respectively. Sucrose treatment prolonged the vase life of flowers. Except control and 250 mg/L 8-HQS, content of chlorophyll was rapidly decreased after 6 days at upper, middle and lower leaves in order.

There is a need to breed and distribute domestic varieties for Lilium Asiatic hybrids because most of the lily bulbs cultivated in Korea imported from foreign country. The genetic resources of Lilium Asiatic hybrids, 'Buff Pixie', 'Orange Matrix' and 'Tiny Puppet', which were collected from 2001, had been self-pollinated from 2004 to 2012. In 2012, Lilium Asiatic 'Lovely LiASong' as an F₁ hybrid was bred through crossing 'L₂-12-1' and 'L₂-35-4' obtained by 4th self-fertilization. 'Lovely LiASong' had a bowl shaped single flower with a few spots and medium-sized flower, 8.7cm in flower diameter. The number of flowers per plant was 4.9, which was relatively more flowers than other cultivars. And the flower inflorescence had umbellate and racemose while the attitude of longitudinal axis was erect. The plant height was 33.4cm with 30.4 leaves per plant and 7.2cm in leaf length. The 'Lovely LiASong' showed a high consumer preference because it had a relatively longer flowering period, larger flower diameter and number of flowers than those of the control, 'Tiny Ghost'.

This study was conducted to investigate the flower organ removal effect on Atractylodes macrocephala Koidz which was introduced from China. The results were summarized as follows; The plant height of Flower Organ Cutting(F.O.N.C.) treatment short by 1.7∼2.5 cm compared to Flower Organ Non-Cutting(F.O.N.C.) treatment. But number of stem and stem diameter of F.0.C treatment were similar to that of F.O.N.C. treatment. The fresh weight of above-ground part of F.O.N.C. treatment was decreased 48∼60% compare to F.O.C. treatments. The later was period of F.O.C., the higher was fresh weight of above-ground part. The growth of underground part was more F.O.C. at July 15 and Aug. 20 treatments than F.O.N.D treatment. The dry rhizome yield of F.O.C. at July 15 treatment was increased 40% compare to F.O.N.D treatment. Essential oil content of F.O.C. at July 15 treatment was increased 12% compare to F.O.N.D treatment.
