This study investigated the responses of Eremogone juncea flowering characteristics to exogenous 6-benzylaminopurine (BAP) and gibberellic acid3 (GA) treatments. Overwintered E. juncea plants were sprayed with seven treatments: no hormones; 200, 400, and 800 mg·L-1 BAP; and 200, 400, and 800 mg·L-1 GA. All treatments showed 100% flowering, and the exogenous BAP and GA treatments did not affect the time to flowering, whereas the hormone treatments influenced floral organ development. BAP significantly decreased the floret diameter and inflorescence length with increasing BAP concentration, although the 400 and 800 mg·L-1 BAP treatments showed similar values. BAP also caused abnormal flowers with a large gynoecium and stamens with small anthers and short filaments. However, GA significantly increased the floret diameter and inflorescence length, although 800 mg·L-1 GA treatment did not affect the floret diameter. In the vegetative parameters, the leaf length tended to increase as the GA concentration increased. These results indicate that BAP and GA affect the flowering quality of E. juncea and can enhance the value of cut flowers, such as flower size and inflorescence length, by making the flowers larger overall.
본 연구는 정원 장미에서 화색과 향기의 상관관계를 분석하기 위해 개화단계 동안 화색소와 향기물질 구성의 변화를 조사하였 다. 화색과 향기 특성이 다른 세 품종의 정원 장미를 식물재료로 이용하였다. ‘Faustinia’는 황색 꽃잎과 tea-type향을 가지며, ‘Liparfum’은 적색 꽃과 sweet-type향을, ‘Tchaikovsky Meichibon’ 은 약한 향의 백색 꽃을 피운다. 개화과정을 S1에서 S5까지 5단 계로 나뉘어 설정하였다. 세 품종에서 꽃과 꽃잎의 크기, 꽃잎의 생체중과 같은 형태적 특성은 S1에서 S4로 개화가 진행됨에 따 라 증가했다. ‘Faustinia’와 ‘Liparfum’은 S3까지 화색이 선명하고 밝아지고 이후 퇴색되어 a*와 b*값이 감소하였다. 세 품종 모두 향기는 S3~S4에서 가장 강했다가 S5에서 감소하였다. ‘Faustinia’ 의 총 카로티노이드와 ‘Liparfum’의 총 안토시아닌 함량은 S1대 비 S3에서 약 7.2~40.5배 증가하였고 S5에서 약 30.6%까지 현저 하게 감소하였다. 백색 계열 ‘Tchaikovsky Meichibon’의 화색소 함량은 개화 과정 중 큰 변화를 보이지 않았으나 S5에서 2.3배 감소하였다. 향기물질은 화색소 변화와 유사한 패턴을 보였다. 2-phenylethanol과 3,5-dimethoxytholuene은 모든 품종 ‘Faustinia’ (84.2%), ‘Liparfum’(89.6%), ‘Tchaikovsky Meichibon’(94.8%) 에서 높은 함량비율을 보였고, 테르펜 향기물질 구성비율은 역순 으로 높았다. ‘Liparfum’의 안토시아닌은 향기물질 2-phenylethanol (r=-0.51), 3,5-dimethoxytoluene(r=-0.72**), eugenol(r=-0.58*),neral(r=-0.48), geranial(r=-0.42)과 음의 상관관계를 보였으나, 카로티노이드는 명확한 상관성을 갖지 않았다
This study attempted to understand the value of traditional floral wall patterns reflecting the distinct aesthetic consciousness of Korean people and reinterpret the images of floral wall patterns in simplified forms. In addition, the study created new floral patterns to apply them to the design of neckties and scarves. In a methodological aspect, the computer design software programs Adobe Illustrator CS2 and Adobe Photoshop CS2 were used to make the traditional floral wall patterns motifs. Four basic motifs for a new formative image were set using graphical functions such as omitting, simplifying, overlapping, repeating, and/or reducing shapes based on floral wall patterns, and each motif was developed in two variations with different colors applied to them. Each of the set motifs was expressed in a repeated arrangement and in a modified pattern of 45 degrees. Necktie design with a floral wall pattern made use of the motifs developed through a variety of effects such as simplification, repetition, size variation, and gradation and the pattern modified at a 45°for application. Scarf design employed and applied the existing motifs in an appropriate manner for design purposes and reconstructed and expressed them through such effects as repetition, rotation, compositional variation and gradation.
대나무를 이용하여 화훼장식품을 개발하고 그 작품을 전시하였다. 대나무의 길고 굵은 가지를 교차시켜 현대적 디자인을 하고 그 사이에 식물을 고정시켜 작 품성을 높였다. 대나무 선단부의 긴 가지와 잎을 밀집 시켜 숲을 만들고 그 속에 안정감 있는 분화류를 배 치하였다. 대나무를 세로로 잘라 기둥을 만들고 그 선 단부에 대나무 용기를 부착시켜 식물을 심었다. 대나무 기둥의 움직임에 의한 리듬감을 표현하였다. 대나무의 잔가지들을 서로 엮어 면을 만들고 그 면에 식물을 매 달아 벽장식 작품을 구성하였다.
This study analyzes the design elements and principles of flower arrangement to develop programs that can be applied to elementary after-school and aims to demonstrate its effectiveness through a questionnaire. For the study, analyzes of flower design elements and principles through a literature and previous studies that about gardening activitie’s impact on children. In addition, analyzes the elementary school curriculum and extracts the flower design elements and principles that can be connected to the elementary curriculum to develop the flower arrangement program. Developed programs are proven by conducting surveys for theirs fitness as elementary after-school program and children's anticipated preference for 20 elementary school teachers and 20 lecturer who directly teach the after-school classes in the elementary school. The results were as follows. First, flower design elements and principles of design and flower arrangement theory was connected with the elementary school curriculum. Second, by analyzing the elementary school curriculum that can be connected flower design, develop flower design after-school programs in 15 periods. Programs are five associated with design elements and principles, five about color that most associated with elementary curriculum and five about trends and lifestyle associated with flowers. Developed programs are limited to the possible level that applies to the elementary after-school classes about cost, time, and technology. Third, the programs are proven by teachers and after-school classes lecturer. According to survey results, the art is the most relevant to flower design and developed 15 programs were proven their suitability to elementary after-school programs.
본 연구는 몇가지 희귀자생식물의 대량증식을 위하여 종자의 저온저장온도와 발아온도의 영향을 알아보고자 실시한 결과는 다음과 같았다. 저온저장온도 실험에서는 두메부추(Allium senescens L.)의 종자는 5℃에 저장시 발아율이 91.5%로 가장 높은 것으로 나타났으며 9℃의 비교적 고온에서는 발아율이 감소하는 것으로 나타났고 흑산도비비추(Hosta yingeri S. B. Jones)는 9℃에서 다소 발아율이 증가한 것으로 나타났다. 홍도원추리(Hemerocallis hongdoensis M.G.Chung & S.S.Kang)의 저장온도 실험은 모든 처리구에서 비슷한 발아양상을 보였고 5℃에서 저장시 발아율이 80%로 가장 높았으며 5℃에서 9℃로 저장온도가 높아질수록 발아가 낮아지는 경향을 보였다. 발아온도 실험은 두메부추는 20℃, 25℃의 처리구에서 발아가 향상된 결과를 나타내었으며 특히 20℃에서는 생육이 곧고 강건하게 자라는 것을 알 수 있었다. 흑산도비비추는 발아온도 20., 25℃에서 높은 발아율을 보였다. 홍도원추리는 발아온도가 증가할수록 발아율이 증가하는 경향을 보이며 25℃의 경우 발아율이 70%로 가장 높았으나 30℃의 고온에서 발아율이 현저히 감소하였다.
To find out the relationship between pod development and cytokinin contents during reproductive stage of peanut, the cytokinin contents, trans-zeatin ribo-side (t-ZR) and dihydrozeatin riboside (diZR), were investigated at 0, 7, 14, 21 and 28 days after flowering (DAF). The amounts of t-ZR and diZR in cotyledon and first branch among primary branches were 3, 448 pmol/g (FW) and 4, 824 p/g (FW), respectively, which were higher than those of other branches. The t-ZR and diZR contents of lower parts on the branch from cotyledon node at 7 DAF were 579 pmol/g (FW) and 2, 028 pmol/g (FW), respectively, which were higher than those of upper parts. The cytokinin contents of reproductive organs as flowering progressed were increased at 0 and 14 DAF on branch and position of node. The cytokinin contents of upper part with pruning the lower part on the branch from cotyledon node were high 112-337% at 7 DAF and 14 DAF compared with those of the control. In case of remove the upper part of the first internode on main axis, t-ZR contents was 4.7 times higher than diZR contents at 7 DAF. The pod setting rate of flower and position on the branch from cotyledon node was closely related to the cytokinin contents during floral reproductive stage.
Astragalus membranaceus has flowers that are similar to that of the legume family, but shows poor bearing when self-pollination is induced. Thus, this study was carried out observing the ripening procedure of pistils and stamens and development stages of pollen in the context of the birth and growth of the flower. As to the bearing of the flower of A. membranaceus, few pod setting and 13% pod setting were observed when self-pollination is induced by paper-bag covering or artificial pollination treated respectively. The result indicates that A. membranaceus is a cross-pollination plant. A pistil grew faster than a stamen until just before blooming. The flower size was about 17.0mm~times 4.0mm. Pistils and stamens had the same length after flowering. Pollen mother cells passed through meiosis and mitosis when its length reached around 3.5mm, thus creating the tetrade when 4 mm long. Pollen attained full growth when the bud was about 10mm long. An anther was found to tend to dehisce when the length of a bud reached around 12.0mm. As to the shape of pollen, about 70 % were normal. 1% and 30 % were small or empty pollen respectively. The result indicates that pollen of A. membranaceus attains full growth just before anther dehiscence which occurs before blooming while pistils grow faster than stamens until before flowering
