We analyzed the effects of various LED light treatments (red 655 nm, blue 456 nm, white and mixed light) on growth pattern, gene expression and flavonoid contents in lettuce leaf. Plants treated with mixed light (red+blue+white) showed better growth performance than those treated with single LED and...

식물에서 광 스트레스가 미치는 영향은? | 식물에서 광 스트레스는 생장 및 발육에 가장 많은 영향을 끼치며, 에너지원을 공급하는 중요한 역할을 담당하고 있다(Wang et al. 2009). | |
적색광과 청색광을 혼합한 혼합광은 상추에 어떠한 영향을 미치는가? | 본 연구의 결과에서도 적색광과 청색광을 혼합하여 처리한 상추에서 기능성 물질의 함량이 높게 나타났으며, 생육도 양호하였다. 따라서 식물공장 내 상추의 생육과 품질을 높이기 위해 혼합광을 적절하게 사용함으로써 색소 관련 생합성 경로상의 유전자 발현량을 조절하여 색소함량 등에 영향을 준다. 많은 작물에 있어서 적색의 파장 영역은 생육촉진을, 청색광과 UV 영역은 색소 및 기능성 물질 함량의 증대 효과가 있음이 수많은 연구를 통해 밝혀진 바 있으나, 색소 등 물질함량을 극대화시키기 위한 전략으로 청색광의 비율을 높이면 상대적으로 생육량이 떨어져 상업적 생산이 어려울 수 있으므로 작물에 따른 적색광과 청색광의 적합 비율, 에너지 효율을 고려한 광도 조건에 대한 면밀한 검토가 필요하리라 판단된다. | |
식물의 생육 및 색소계 물질 형성에 직접적인 영향을 미치는 파장은 무엇인가? | 2009). 식물은 다양한 광질에 민감하게 반응하며, 이 중 적색파장대의 피토크롬 수용체와 청색파장대의 크립토크롬과 포토트로핀 수용체가 식물의 생육 및 색소계 물질 형성에 직접적인 영향을 주고 있다(Carvalho et al. 2011). |
