  • A new Hibiscus cultivar 'Daewangchun', having vigorous growth, uniform plant habit, upright, compact branches, and a long red eye was developed through interspecific crosses between H. syriacus 'Samchully' (♀) and H. sinosyriacus 'Seobong' (♂). The Hibiscus breeding program was initiated in 2005 and Hibiscus ${\times}$ 'Daewangchun' was preliminarily selected as '05-R-204' in 2 008 due to its vigorous growth and stable flower quality w ith rich pink flowers. The s elected line was further evaluated for different growth characteristics, leaf shape, leaf size, and flowering characteristics, as well as tested for distinctness, homogeneity, and stability during 2010-2012. The new cultivar 'Daewangchun' had violet pink flowers (RHS N80C) with a long red eye spot, medium size and fan petals. The size of flower was 12.0 cm and size of the red eye was 3.0 cm. Leaves were 8.7 cm long and 4.7 cm wide. After plant characteristic evaluation for 3 years (2010-2012), 05-R-204 was registered as cultivar 'Daewangchun' (4731, No. of plant variety protection rights) in 2013. This newly developed cultivar 'Daewangchun' has tall vigorous growth and unique flowers with a long red eye and can be used as specimen plants in landscaping.

  • The purpose of this research is to analyze the effects of persimmon juice and hibiscus flowers extract to perform combination dyeing of silk fabrics, with respect to color changes, fastness, and functionality. The optimal conditions as a result, were shown at 100% of dye concentration, $40^{\circ}C$ of dyeing temperature and 30 minutes of dyeing time while in terms of dye uptake depending on the kind of mordants and methods. The highest K/S value was recorded at pH 3, pre-mordants of $CuSO_4$, and $SnCl_2$, post-mordanting. After repeated dyeing and post-mordanting, various color change occurred with mordant treatments. Color fastness of dyed fabrics with hibiscus flowers extract was improve considerably by combination dyeing with persimmon juice extract. In aspects of functional properties, it showed excellent results of 99% deodorization rate, 99.9% Staphylococcus aureus rate and 99.9% Klebsiella pneumoniae.

  • The methanolic extract of Hibiscus vitifolius flowers (HVE), was evaluated for neurophamacological activities by carrying out rota rod, locomotor activity and traction performance in mice and swim endurance activity in rats in different dosages (10, 30 and 100mg/kg body weight). HVE showed a significant effect on central nervous system by increasing the time taken for rota rod, traction performance and locomotor activity while swimming time was found to be decreased when compared to normal control animals. These results suggest that HVE possess significant anxiolytic and anti depressant activity which may be attributed to the presence of flavonoid in HVE.

  • This study was performed to provide basic information of the development and breeding of new cultivars of Hibiscus syriacus L., which have more beautiful and diverse flowers. Morphological characteristics of the flowers and leaves, and genetic variation of the flowers color of two Jeoktanshim-line cultivars, Bulsae and Pyungsung, were crossed each other. The result of the cross between Bulsae and Pyungsung are as follows: Mean flower height and width were 5.35 cm and 7.69 cm, respectively. Mean length and width of petal were 5.43 cm and 3.80 cm respectively, and mean length and width of flower pistil were 4.67 cm and 0.44 cm, respectively. The flower color of all ten individuals was the color of the Jeoktanshim-line, and Pyungsung, and all flower type were I-c type.

  • 본 연구는 조경수용 무궁화 우수품종 보급을 위한 유전자원 수집과 특성을 평가하기 위해 최근 국내외에서 육성된 127품종의 1년생 접목묘를 이용하여 2014년부터 2015년까지 2년 동안 생육 및 형태적 특성조사를 실시하였다. 수집된 품종 중 화색 및 꽃이 특이한 품종을 조사하여 무궁화를 조경수로 활용도를 높이는데 기여하고자 하였으며 얻어진 결과는 다음과 같다. 최근 국내외에서 육성된 품종들의 화색별 분류로는 크게 분홍색 단심(pink color with red eye spot), 흰색 단심(white color with red eye spot), 붉은 자주색 단심(purplish red color with red eye spot), 분홍보라색 단심(violet pink color with red eye spot), 심홍색 단심(crimson color with red eye spot), 흰색 바탕에 붉은색 무늬의 이중색(asadal), 흰색(white color), 푸른색(blue color) 등 총 8종류로 분류되었다. 화색이 붉은 자주색으로서 적색이 강한 꽃으로 국내에서 육성된 품종으로 '광명', '난파', '노스페이스', '불새', '비단', '송암', '영창', '적퍼소', '키호', '탐라', '화수레드', '환희' 등이 있었으며, 국외에서 육성되어 국내에 도입된 품종으로는 'Aphrodite', 'Dr. Uemoto', 'Freedom', 'Pink Cup', 'PS 80-1', 'Purpureus Variegatus', 'Red Giant', 'Woodbridge' 등이 있었다. 화색이 분홍보라색으로서 특이한 품종으로는 '꼬마', '도투락', '명미', '병화', '산처녀', '태화', 'Hikari-hanagasa', 'Little Kim Violet' 등이 있었다. 화색이 심홍색으로 기존의 꽃에서는 볼 수 없는 특이한 품종으로 '종무'와 'Ruffled Satin' 등이 있었다. 최근 국내외에서 육성된 품종중 조경수용 소재로 보급할 수 있는 품종중 기존 품종에 비해 꽃의 크기가 큰 품종으로 무궁화 종간교잡종인 Hibiscus hybrid 'Daewangchun', 'Daeil', 'Jina' 등이 있었다. 반면 꽃이 작고 조경적 가치가 높은 품종으로 '꼬마', '미백', '안동', '릴킴', '은하수' 등이 있었다. 백단심계 무궁화 '꼬마' 품종은 수고가 작은 왜성형으로 꽃의 크기가 5.2cm로 작은 소형화 품종으로 나타났다. 기존 품종에 비해 단심의 길이가 긴 품종으로 '훈장'과 '하이리레드'가 있었다. 홍단심계 무궁화 '훈장'은 꽃의 크기는 12.0cm로 중간크기이나 단심길이는 4.8cm로 지금까지 육성된 품종중 가장 긴 품종이었다. 또한 홍단심계 무궁화 '하이리레드'의 단심길이 역시 4.2cm로 꽃잎 길이에 비해 단심의 길이가 길어 조경적 가치가 높은 것으로 판단되었다.

  • In this study, we investigated whether Hibiscus manihot flowers (HMF) exhibits immunostimulatory activity in RAW264.7 cells. HMF increased the production of immunostimulatory factors such as NO, iNOS, IL-1β and TNF-α in RAW264.7 cells. TLR2 and TLR4 blocked HMF-mediated production of immunostimulatory factors in RAW264.7 cells. In addition, the inhibition of MAPK signaling pathway reduced HMF-mediated production of immunostimulatory factors. From these results, HMF is thought to promote the production of immunostimulatory factors through activating TLR2/4/MAPK signaling in macrophages. It is believed that HMF can be developed as an agent related to immune enhancement in the future.

  • In a project to study the hepatroprotective effect of some plant extracts four plants Ephedra foliate Boiss, Alhagi maurorum Medikus, Capsella bursa-pastoris (L.) Medik. and Hibiscus sabdariffa L. were studied. The ethanol extract of the aerial part of the first three plants and the flowers of H. sabdariffa were subjected to hepatoprotective assays using Wistar albino rats. Liver injury induced in rats using carbon tetrachloride. The biochemical parameters; serum glutamate oxaloacetate transaminase (SGOT), serum glutamate pyruvate transaminase (SGPT), alkaline phosphatase (ALP) and total bilirubin were estimated as reflection of the liver condition. Based on the good results of the biochemical parameters measurements, histopathological study was performed on the liver of rats treated with E. foliate. The normal appearance of hepatocytes indicated a good protection of the extract from carbon tetrachloride hepatotoxicity. All the results were compared with silymarin, the reference hepatoprotective drug.

  • Hibiscus syriacus were surveyed to study the growing temperature, relative humidity and growing responses shown at different elevations of Kangwon Province, and results of the assessment are summarized as follows 1. Growing responses as represented by leaf length, leaf width, shoot length, number of flowers and flowering duration, were decreased as the elevation increased, while the degree of defoliation was increased. 2. The important factor determining the growing responses to the elevation was the maximum and minimum temperatures, particularly those of July, August, and September. 3. The aphid occurrence on Hibiscus syriacus decreased as the elevation increased. Leading factor determining the population was relative humidity which increased as the elevation increased.
