ABSTRACT: We aim to elucidate suitable mixed color of light during development of fruit body in Pleurotus ostreatus. The four mixed color of LED(Light Emitting Diode), blue and white, green and white, blue and green and green and red LED, were irradiated for formation of fruit-body. First, as effect of mixed color of LED, the properties of fruit body of P. ostreatus in blue and white LED irradiation were showed higher commercial yields than those in control(fluorescent lamp). And the ergothioneine was the highest at the blue and white LED. Second, we could obtain higher commercial yields than those at the 1 µmol/m 2 /s of light intensity by blue and white LED in P. ostreatus. 서 론 LED (Light Emitting Diode)는 식물재배에 있어 소규 모 공간 내 설치가 용이하며, 수명이 길고 분이나 초 단위 로 간헐적 조사가 가능하여 다른 광원에 비해 전력소모량 이 적어 경제적이다(Brown et al, 1995). 또한 최근에 식 물공장과 아울러 LED의 농업적 활용도가 제시되고 있으 며, 작물이나 채소 및 화훼 등에 적용하기 위한 연구가 활 발히 진행되고 있으나 국내에서 버섯재배에 대한 LED의 적용연구는 매우 미흡한 실정이다.
