  • Shoot weight of Orostachys japonicus should determine its profitability. The study was done to determine the effect of phosphorus and potassium fertilization (0, 5, 10, 20 kg $P_2O_5$ or $K_2O$ /1000 $m^2$) on its growth, morphological characters, and flowering. Night-break treatment of 2 hours at midnight were done since Aug. 25 when afterward samples were taken every 4 weeks to Nov. 16. Growth, morphological and flowering related characters were measured from each sample. Plant height, inflorescence length, number of leaves including bracts and stem diameter were increased with increased P and K levels. Leaf and bract, floret, shoot and total dry weights showed similar response to the above morphological characters although P fertilization more increased them than K fertilization. Florets were more formed with increased P and K levels but were not flowered due to the night-break treatment, meaning that P and K fertilization had little effect on anthesis of the florets formed.

  • 'Usul' is a traditional medicinal herb, which has anti-inflammatory activities is distributed in India, Nepal, China, Korea, Japan. Korea pharmacopeia listed 'Usul' as either a species of Achyranthes japonica (Miq.) Nakai or A. bidentata Blume. Recent taxonomic studies in China and Japan delimited these taxa as two varieties, A. bidentata Blume var. bidentata and var. japonica Miq. A multivariate morphometric study of Achyranthes bidentata complex was undertaken to assess the entities of taxa that usefully could be recognized. Five quantitative characters were reviewed and analyzed with 293 specimens from Korea. The univariate analysis of inflorescence length, interval between florets, angle between floret and floral axis indicated that ranges among all taxa were continuous. However, quantitative characters of membrane size and the number of hairs within 4 were useful to identify two varieties. In PCA, the first three principal components accounted for 89.4% of the total variance. PCA revealed that var. bidentata showed distinctions in morphological attributes from var. japonica entity. Therefore, continued recognition at the infraspecifc level for these taxa is supported.

  • The New bicolor spray rose (Rose hybrida Hort.) cultivar was developed by line selection in 2000 at the Flower Breeding Research Institute, Gyeongnam ARES. Characteristics were investigated three times from 2003 to 2006. 'Yellow King' was crossed between 'Spring Time' and 'Flair' and it has a Yellow Orange-group color (RHS No. 16A), few thorns and spray flower with a good harmony between ray floret and flower center. The vase life of cut flower was 9.1days. It was registered as commercial cultivar in 2006. This new cultivar could be planted in most of greenhouse production region of Korea and will be released to general rose growers in 2007.

  • A new gerbera (Gerbera hybrid Hort.) 'Azalin' was bred by the National Institute of Horticultural & Herbal Science in 2009. 'Basic' and 'Rosabella' which had pink color and semi-double flower were crossed in 2006. After investigation of the characteristics for four years (from 2006 to 2009), it was selected specially for the use of cut flower. The 'Azalin' had brilliant pink color (RHS RP68A) with green disc center. The flower was semi-double and 10.6 cm in diameter. It had a thick peduncle of which upper and lower width were 3.7 mm and 5.5 mm, respectively. The average days to first flowering of 'Azalin', 88.5 days, was approximately 8.7 days earlier than the control cultivar. And its average yield, 55.8 stems per plant, was also 7.4 stems per plants more than the control cultivar.

  • 'Double Shine', a cultivar of Gypsophila paniculata was newly developed for the cut flowers by Jeollabuk-do Agricultural Research & Extension Services. It has morphological characteristics of the spreading plant type, double florets of many petals and two pistils, emarginate petal tip and cup shaped calyx. Also 'Double Shine' has several traits such as strong flower stalk, bright colored flower, narrow branching angle and more or less resistance to powdery mildew and pest injury. Furthermore, 'Double Shine' produced higher primary branches, and longer flower stalk length with internodal length and than did a check variety 'Bristol Fairy' during summer cultivation in subalpine areas. Blooming of 'Double Shine' was delayed by 16 days, its floret had broader width, compared to 'Bristol Fairy'. Moreover, 'Double Shine' produced normal flowers with two pistils and 8.5 stamens, with little production of malformed flowers in the high temperature condition.

  • A freesia (Freesia hybrida Hort.) 'Shiny Bell' was developed for the cut flower in the National Institute of Horticultural Herbal Science in 2012. This hybrid was selected from a crossing between cn. 'Teresa' and 'Rossini', which is white semi-double flowering and red double flowering, respectively. in 2004. Morphological characteristics of the selected hybrid were investigated for 3 years from 2009 to 2011, and then it was named 'Shiny Bell'. 'Shiny Bell' had red color of RHS W155C, and double flower. The growth of the plant was vigorous and the average height was 109.3 cm. The average flower width was 5.8 mm, number of floret per stalk was 11.3, and stalk length was 8.5 cm. The average yield, 7.3 Branches per plant, was 3 stems per plant more than the control cultivar. The average days to first flowering of 'Shiny Bell', was 143.3 days, and it was approximately 7 days later than the control cultivar. The average yield of 'Shiny Bell' was 4.0 cormlets per plant.

  • This experiment was conducted to investigate the effects of a growth retardant uniconazole treatment time on the growth and flowering of Cymbidium Pine Clash 'Moon Venus' and Cym. Green Sour 'A One' in order to develop a substitutional technique on the highland cultivation. Leaf growth of both cultivars was more remarkably reduced by earlier uniconazole treatment time and growth reduction of 'A One' was more remarkable than 'Moon Venus'. Flowering time of 'Moon Venus' treated with uniconazole at May 7 and 27 was accelerated by 5 and 6 days respectively. Moreover, the number of inflorescences and florets showed a tendency to increase. However there was no difference in flowering time of 'A One' among treatments but there was a tendency to decrease in the number of inflorescences and florets by uniconazole treatment. In both cultivars, there was no difference among treatments in the length and width of lower sepal which represent the floret size.

  • A freesia (Freesia hybrida Hort.) 'Dancing Flame' was developed for the cut flower in the National Institute of Horticultural Herbal Science in 2007. This hybrid was selected from a crossing between a seedling 'Vulcano' and 'Sailor', which is scarlet double flowering and purple single flowering, respectively, and 'Figaro' which is bright red color and semi-double flowering, in 2000. Morphological characteristics of the selected hybrid were investigated for 3 years from 2005 to 2007, and then it was named 'Dancing Flame'. 'Dancing Flame' had red color (RHS R44B) and single flower with yellow center color (RHS Y9A). The growth of the plant was vigorous and the average height was 93.3 cm. The average flower width was 60 mm, number of floret per stalk was 14.3, and stalk was 13.2 cm length. The average yield, 7.8 cuttings per plant, was 2.5 stems per plant more than the control cultivar. The average days to first flowering of 'Dancing Flame', 133 days, was approximately 5 days earlier than the control cultivar. And its average yield, 7.1 cormlet per plant, was also 2.5times more than the control cultivar.

  • Experiment was performed to investigate the effect of light intensity on growth and flowering status of Korean native Dianthus superbus var. longicalycinus, Sedum middendorifianum, Hemerocallis aurantiaca, Iris ensata var. spontanea and Aquilegia buergeriana var. oxysepola for effective landscaping. Number of floret and flower stalk per a plant were markedly increased under full sun(about 100,000lux), and decreased with decreasing light intensity in all tested plants. This result indicate that it will be cultivated in the open for promote landscaping values. However, leaf area and plant height were more increased under half sun(22,000lux) than open(100,000lux) or shade(7,700lux) in all plants except Sedum middendorifianum. Especially, Hemerocallis aurantiaca had same number of shoot and leaf size, even if planted under shade condition to show a wide adaptation to various light intensities.
