Effects of Plant Factory Cultural Systems on Growth, Vitamin C and Amino Acid Contents, and Yield in Hydroponically Grown Peucedanum japonicum

This study was carried out to investigate the effects of cultural systems on growth, vitamin C, amino acid content, and yield of Peucedanum japonicum grown in artificial light plant factory. Treatments were given with Nutrient Film Technique (NFT), Medium (Perlite), and Aeroponics. Plant height was the highest in NFT system as 10.2cm, and was the shortest in Perlite as 8.9cm. Fresh leaf weight was the high in order of Perlite, NFT, and Aeroponics. Total phenolic compounds was different from cultural systems in order of Aeroponics as $117.84mg{\cdot}100g^{-1}\;GE$, NFT as $98.57mg{\cdot}100g^{-1}\;GE$ and Perlite as $74.62mg{\cdot}100g^{-1}\;GE$. Total flavonoid content of Aeroponics is $0.12mg{\cdot}100g^{-1}$ but that of NFT and Perlite treatments is not detected. Vitamin C content in Aeroponics as $108.23mg{\cdot}100g^{-1}$ was significant different from Perlite as $88.05mg{\cdot}100g^{-1}$ as and NFT $80.83mg{\cdot}100g^{-1}$. Total dietary fiber content was higher Aeroponics than Perlite and NFT. Cystein content was the highest in Aeroponics as $46.76mg{\cdot}100g^{-1}$ and methione content was the lowest in Perlite as $75.64mg{\cdot}100g^{-1}$. Mineral content of leaves was high in order of K, Ca, P and Mg in all treatments.

식물공장 재배시스템에 따른 방풍나물의 생육, 비타민 C와 아미노산 함량 및 수량에 미치는 영향

본 연구는 방풍나물의 인공광 식물공장에서 재배시스템에 따른 생육, 비타민 C, 아미노산함량, 수량에 미치는 영향을 구명코자 실시하였다. 박막수경(NFT), 배지경(Perlite), 분무경(Aeroponics) 등 3처리를 하였다. 초장은 NFT 처리에서 10.2cm 가장 길었으며, Perlite 처리에서 8.9cm로 가장 짧았다. 주당 엽 생체중은 Perlite, NFT, Aeroponics순으로 무거웠다. 총 페놀 함량은 Aeroponics가 $117.84mg{\cdot}100g^{-1}\;GE$로 가장 높았고, NFT $98.57mg{\cdot}100g^{-1}\;GE$, Perlite $74.62mg{\cdot}100g^{-1}\;GE$ 순으로 재배 방법에 따라 차이를 나타냈다. 총 플라보노이드는 Aeroponics에서만 $0.12mg{\cdot}100g^{-1}$가 검출되었으나, NFT와 Perlite 처리구에서는 검출되지 않았다. 비타민 C 함량은 Aeroponics가 $108.23mg{\cdot}100g^{-1}$으로 가장 높았으며, Perlite가 $88.05mg{\cdot}100g^{-1}$, NFT가 $80.83mg{\cdot}100g^{-1}$으로 처리에 따라 통계적인 유의성을 나타냈다. 총 식이섬유소 함량은 Aeroponics가 Perlite와 NFT보다 높았다. Cystein 함량은 Aeroponics에서 $46.76mg{\cdot}100g^{-1}$로 가장 높았으며, methionine 함량은 Perlite가 $75.64mg{\cdot}100g^{-1}$로 가장 낮았다. 무기질 함량은 모든 처리에서 K, Ca, P, Mg 순으로 높았다.
