적색광이 식물에 끼치는 영향은 무엇인가? | 특히 식물체 내 유용 물질이나 색소 합성 조절 등의 기능을 수행할 수 있다는 장점이 있다(Caldwell과 Britz, 2006; Heo 등, 2010). 적색광은 여러 작물들에서 초장, 근장, 생체중, 엽면적 등의 생장에 효과적이고(Johkan 등, 2010; Nishimura 등, 2007, 2009; Nishioka 등, 2008), 콩 모종에서 엽면적, 베타 카로틴 및 항산화도를 증가시키는 것 으로 보고되었다(Wu 등, 2007). 청색광은 상추 지하부 및 잎 두께(Johkan 등, 2010), 오이잎의 루비스코(rubisco) 활성, 자당 및 전분 함량(Wang 등, 2009), 질소 및 엽록 소 함량과 기공전도도(Hogewoning 등, 2010; Savvides 등, 2012)를 증진시키는 것으로 보고되었다. | |
광 형태형성 반응이란? | 또한 청색광은 제라늄 모종 초장을 억제시키는데(Appelgren, 1991) 이는 크립토크롬 색소와 관계가 있다고 하였다(Zhao 등, 2007). 이러한 특정 파장대의 광을 흡수하는 광 수용체는 피토크롬(적색광 및 원적색광 파장 흡수), 크립토크롬 및 포토트로핀(청색광 및 근자외선 [UVA] 파장 흡수)이 있다고 알려져 있으며, 이들은 각 파장 자극을 인식하고 광 신호전달 기작에 의해서 개화, 굴광성, 기공 개폐 및 안 토시아닌 합성 등에 영향을 주게 되는데, 이런 현상을 광 형태형성(photomor-phogenesis) 반응이라고 한다(Carvalho 등, 2011; Sulivan과 Deng, 2003). 자외선(Ultraviolet radiation)은 파장에 따라 UVA(315-380nm), UVB (280- 315nm), 및 UVC(100-280nm) 영역으로 구분되는데 UVC 는 오존층에 의해 차단되어 지표면에 도달하는 자외선 95%가 UVA다(Kim과 Lee, 2016). | |
비타민 C함량이 높은 채소 TOP5는? | 시금치는 카로틴과 섬유소가 풍부하여 변비에 효능이 뛰어나고 엽록소가 다량 함유되어 항암 효과 및 동맥경화를 예방하는 대표적인 알칼리성 채소로 알려져 있다 (Maeda 등, 2005). 질병관리본부의 국민건강영양조사 결 과에 의하면 시금치의 주요 영양소 급원 순위는 식이섬유, 칼륨, 리보플라빈은 21위, 비타민 A는 11위, 비타민 C는 9위로 사과, 감, 배추김치, 오렌지, 딸기, 참외, 무, 고구마 다음으로 비타민 C의 주요 급원이다(KNHNES, 2017). 비타민 C함량은 채소 생장 조건에 따라 다를 수 있다고 하였다(Kim 등, 2010). |
