Abstract

This study was carried out to investigate the effects of artificial light sources on growth and yield of hydroponically grown Peucedanum japonicum in plant factory. Treatments were composed with; florescent lamp(FL) as control, and LED lights; R:B(2:1, RB), R:B:W(2:1:3, RBW), and R:B:G:W(2:1:0.5:3, RBGW). Plant height of RBGW and FL treatments were superior to RB and RBW. Leaf weight of RBW and RB were superior to FL and RBGW. There were no significant difference of leaf length and thickness among the treatments. Lightness of leaves was same tendency with plant height. Total phenolic compound content was the high in order of RB as $105.77mg{\cdot}100g^{-1}$ GE, RBW as $92.52mg{\cdot}100g^{-1}$ GE, FL as $89.08mg{\cdot}100g^{-1}$ GE, and RBGW $82.00mg{\cdot}100g^{-1}$ GE. Total flavonoids were not detected in all treatments. Vitamin C content was the highest in RB and the lowest in FL. Total dietary fiber were the highest in FL and the lowest in RBGW. There was no significant difference cystein and methionine contents among the treatments. Concludely, yield, total phenolic compounds, and vitamin C content was high in RBW and RB. We reached conclusion that RBW is best artificial light source considering yield, functionality and eye fatigability when work. We recommend to further study LED pulse and duty rates for increasing functionality.

본 연구는 식물공장 인공광원이 방풍나물의 생육 및 수량에 미치는 영향을 구명코자 수행하였다. 식물공장의 인공광원으로 형광등(FL), LED R:B(2:1, RB), R:B:W(2:1:3, RBW), R:B:G:W(2:1:0.5:3, RBGW) 등 4처리를 사용하였다. 엽중은 RBW와 RB가 FL과 RBGW 보다 우수하였다. 엽장과 엽후는 처리간에 유의성을 나타내지 않았다. 잎의 명도는 초장과 같은 경향을 나타냈다. 총 페놀함량은 RB가 $105.77mg{\cdot}100g^{-1}$ GE로 가장 높았고, RBW $92.52mg{\cdot}100g^{-1}$ GE, FL $89.08mg{\cdot}100g^{-1}$ GE, RBGW $82.00mg{\cdot}100g^{-1}$ GE 순으로 높았다. 총 플라보노이드 함량은 모든 처리에서 검출되지 않았다. 비타민 C 함량은 RB에서 가장 높았고, FL에서 가장 낮았다. 총 식이섬유소 함량은 FL에서 가장 높았고, RBGW에서 낮았다. Cystein과 methionine의 함량은 처리간에 통계적인 유의성을 나타내지 않았다. 결론적으로 수량, 총 페놀함량, 비타민 C 함량은 RBW와 RB에서 높았다. 수량, 총 페놀 함량, 비타민 C 함량 및 작업자의 눈 피로도 등을 고려 할 때 인공광원으로써 RBW가 가장 적합한 것으로 판단된다. 향후 기능성 성분 증진을 위해 듀티비 등 후속 연구가 필요하다고 판단된다.
