BACKGROUND: In korea, sweet persimmon(Diospyros kaki) cultivation is front to abiotic stresses such as frost damage at fruit maturing stage. The cold and rapid freezing stresses are most damaging to fruit production which is most actively progressed in late fall. This study was performed to evaluate...

엽록소 형광 현상이란 무엇인가? | 엽록소 형광 현상은 Kautsky와 Hirsch(1931)의 광합성 과정 중 빛의 섬광에 의한 CO2 흡수동화의 변화원인에 대한 연구에서 비롯되었으며, 비파괴적 방법을 통한 식물체의 비생물학적 스트레스(abiotic stress) 지표 및 건전생장에 관한 정량적인 평가를 할 수 있는 분석법이다. 지금까지 chlorophyll a의 형광현상을 응용하여 광합성 기구의 일련반응을 해석하려는 연구가 많이 시도되어 왔다(Govindjee, 1995; Strasser et al. | |
식물의 잎 이외에서 엽록소 형광 이미지 분석 기술로 무엇이 가능한가? | 엽록소 형광 이미지 분석 기술은 식물의 잎뿐만 아니라 과일 색소(Pigment)의 광화학 반응 측정 및 광합성 능력 평가가 가능한 것으로 보고되었다(Nedbal and Whitmarsh, 2004; Zushi et al., 2012). | |
우리나라의 기후변화에 따른 이상기상 현상은 어떠한가? | 최저 기온의 상승으로 우리나라 대부분의 지역에서 서리현상일수가 감소하는 추세에 있으나 몇몇 지역의 경우 오히려 증가(Kwon, 2006)하는 것으로 보고되었으며, 국지적으로 발생하는 이상저온으로 인한 농작물의 피해가 우려되고 있는 실정이다. |
