  • 0%, 3%, 5%, and 7% chrysanthemum powder was added to plain bread to investigate its effect on the quality and preservation of bread. The properties of dough, physical changes, and sensory evaluation of plain bread with chrysanthemum powder added were analyzed during storage at room temperature. Volumes of dough and bread were decreased by addition of chrysanthemum powder. Also, the pH and Hunter L (lightness) in bread with chrysanthemum powder were lower than those of the control bread, while its redness, yellowness, and hardness were higher. In sensory evaluation, when more than 5% chrysanthemum was added to bread, aftertaste and overall acceptability were rapidly decreased. In contrast, the addition of chrysanthemum minimized the drop of flavor caused by storage time. In conclusion, chrysanthemum powder added to plain bread improved flavor, which declines with storage time.

  • This study was designed to evaluate to acute oral toxicity and skin irritation of Chrysanthemum dye in Sprague-Dawley (SD) rats. SD rats were orally treated with Chrysanthemum dye at a dose of 0, 1 and 2 ml/kg body weight. After oral administration, the rats were observed for 14days. In primary skin irritation test, SD rats were dermally treated with Chrysanthemum dye and observed for 3 days. To ensure the safety of Chrysanthemum dye such as the following were observed and tested. We examined the body weight, the feed intake, the clinical signs, the ophthalmological test, the histopathological test, the mortality and skin irritation. As a result, no significant differences were found in body weight, feed intake and histopathological test between control and Chrysanthemum dye treated group. In the result of skin irritation test, Chrysanthemum dye did not induce erythema and edema after topical application. Primary irritation index was "0" in the test. Therefore, it is suggested that Chrysanthemum dye has no effect on acute toxicity and side effect in SD rats and is non-irritant material based on the score "0" of primary irritation index.

  • Chrysanthemum is one of the top floriculture species with ornamental and medicinal value. Although chrysanthemum breeding program has contributed to the development of various cultivars so far, it needs to be advanced from the traditional phenotype-based selection to marker-assisted selection (molecular breeding) as shown in major cereal and vegetable crops. Molecular breeding relies on trait-linked molecular markers identified from genetic, molecular, and genomic studies. However, these studies in chrysanthemum are significantly hampered by the reproductive, genetic, and genomic properties of chrysanthemum such as self-incompatibility, inbreeding depression, allohexaploid, heterozygosity, and gigantic genome size. Nevertheless, several genetic studies have constructed genetic linkage maps and identified molecular markers linked to important traits of flower, leaf, and plant architecture. With progress in sequencing technology, chrysanthemum transcriptome has been sequenced to construct reference gene set and identify genes responsible for developments or induced by biotic or abiotic stresses. Recently, a genome sequencing project has been launched on a diploid wild Chrysanthemum species. The massive sequencing information would serve as fundamental resources for molecular breeding of chrysanthemum. In this review, we summarized the current status of molecular genetics and genomics in chrysanthemum and briefly discussed future prospects.

  • 꽃차(Flower tea)는 최근 다양한 제품이 개발되고 소비가 확대되는 등 그 산업적 가치가 증대하고 있다. 꽃차의 향기 특성은 우렸을 때 나타나는 색깔 및 인체에서의 생리활성과 더불어 주요한 꽃차 품질결정 요소이다. 본 연구는 꽃차로의 이용이 활발한 국화과 식물 중 구절초(Dendranthema zawadskii var. latilobum), 국화(Chrysanthemum morifolium), 노랑색 및 주황색 마리골드(Tagetes erecta 'Yellow' and 'Orange'), 그리고 캐모마일(Matricaria chamomilla)의 향기 성분특성을 구명하기 위하여 제조된 꽃차를 headspace-solidphase microextraction/gas chromatography-mass spectrometry (HS-SPME/GC-MS)를 이용하여 분리, 동정하였다. 국화과 꽃차로부터 총 117종의 휘발성 성분이 확인되었는데, 각 꽃차 종류별 동정된 휘발성 성분의 개수, 주요 3개 휘발성 성분과 전체 향기성분 peak중 이들이 차지하는 구성비율(%)은 다음과 같았다: 구절초 64종, camphor (31%), α-pinene(14%), camphene(14%); 국화 60종, camphor(15%), chrysantheny acetate(13%), eucalyptol (11%); 마리골드 '옐로우' 53종, 2,4-heptadienal(26%), trans-isocarveol(21%), cis-β-Copaene(18%); 마리골드 '오렌지' 61종, β-caryophyllene(16%), β-ocimene epoxide(12%), β-ocimene(12%); 캐모마일 50종, β-farnesene(63%), nonane(9%), spathulenol(5%). 국화과 꽃차 5종 모두에서 공통적으로 검출된 성분은 β-caryophyllene, α-pinene, β-farnesene 등 10종이었으며 마리골리 '옐로'는 '오렌지'와 주요 향기성분의 조성에서 뚜렷한 차이를 나타내었다. 비록 그 함량은 낮았으나 구절초, 국화, 마리골드 '오렌지', 그리고 캐모마일은 각각 10종, 12종, 3종 및 13종이었다. 마리골드 '엘로'의 경우 검출된 모든 향기성분은 마리골드 '오렌지'나 다른 국화과 식물의 꽃차에서도 검출된 바, 향기 성분이 다양성이 다소 낮게 나타났다.

  • Root-lesion nematode (Pratylenchus vulnus) and pin nematode (Paratylenchus sp.) were detected with high population density at the spray chrysanthemum greenhouse in Gumi, Gyeongbuk. The average density of P. vulnus and Paratylenchus sp. was 667 and 716 nematodes per 100 g soil and P. vulnus density were distributed 87% to the depth of $0{\sim}30$ cm in greenhouse. When spray chrysanthemum cv Chopin, was transplanted in September 2004 in greenhouse, P. vulnus were 854 nematodes/100 g soil in planting and increased 14,985 nematodes/100 g soils and 1g root after 10 weeks in harvest. Shoot weight and shoot height of spray chrysanthemum decreased 24.8% and 8.0% compared with non-infested P. vulnus after 10 weeks in greenhouse.

  • This study was carried out to investigate the population changes of Liriomyza trijolii (Burgess) on chrysanthemum and its relationship to plant growth and damages. In spring culture of chrysanthemum, L. trifolii adults begun to be attracted by the yellow sticky trap from early May and maintained high population until the middle of July. Larval density increased gradually from late May and reached peak in early July. In autumn culture, the population density of adult was lower than that of spring culture but the number of adult was great in late September and the middle of October. This trend was similar to that of larval stage. Damaged leaves by larva could be found from 4 weeks after transplanting and its rate was low until 5 weeks but increased abruptly after 6 weeks and maintained 70% level until flowering stage in spring culture. Damaged leaves increased with plant growth in some varieties tested in this experiment.
