Dandelion (Taraxacum officinale) is a member of family Asteraceae that grows all over the Korea. Recently, dandelion was cultivated for medicinal crops because of its positive medicinal effects. However, dandelion is considered as a troublesome weed in grass lawns of golf course and orchards. This s...

종자의 발아에는 어떤 요인들이 관여하는가? | 이러한 종자의 발아에는 다양한 생리적, 환경적 요인이 관여를 하는 것으로 알려져 있다. 대표적인 생리적 요인으로는 식물호르몬을 들 수 있 으며, 환경적 요인으로는 온도, 광, 수분을 들 수 있다. 종 자발아를 촉진하는 것으로 알려진 대표적인 식물호르몬지베렐린(gibberellin, GA)은 diterpenoid 화합물의 형태로 색소체(proplastid)에서 geranylgeranyl diphosphate (GGDP)를 전구체로하여 소포체막(endoplasmic reticulum membrane) 과 세포질(cytoplasm)에서 다양한 효소의 작용을 통해 생합성된다(Olszewski et al. | |
서양민들레는 무엇인가? | 서양민들레(Taraxacum officinale Wigg)는 국화과 (Composiae) 민들레속(Taraxacum) 식물로서 전 세계적으로 온대와 한대지방에 넓게 분포하는 다년생 초본식물이며, 우리나라에서도 자생종인 좀민들레, 산민들레, 흰민들레, 민들레와 귀화종인 서양민들레, 붉은씨서양민들레가 자생하는 것으로 알려져 있다(Chon and Park, 2012; Kim et al., 2009). | |
지베렐린은 자연에서 어떻게 합성되는가? | 대표적인 생리적 요인으로는 식물호르몬을 들 수 있 으며, 환경적 요인으로는 온도, 광, 수분을 들 수 있다. 종 자발아를 촉진하는 것으로 알려진 대표적인 식물호르몬지베렐린(gibberellin, GA)은 diterpenoid 화합물의 형태로 색소체(proplastid)에서 geranylgeranyl diphosphate (GGDP)를 전구체로하여 소포체막(endoplasmic reticulum membrane) 과 세포질(cytoplasm)에서 다양한 효소의 작용을 통해 생합성된다(Olszewski et al., 2002). |
