Abstract

Light wavelength is the major factor of fruit body development associated with mushroom cultivation, but its wavelength range in Pleurotus eryngii is poorly understood. Using four kinds of light emitting diode (LED) including blue (475 nm), green (525 nm), yellowed (590 nm) and red (660 nm), we investigated to elucidate suitable light wavelength during primordium formation and fruit body development of P. eryngii on bottle cultivation. Primordia formation did not occur in blue light and red light. The morphological properties of fruit body in fluorescent lamp and blue light irradiation were showed thicker and larger pileus than those in other LEDs. However, length of stipe in fluorescent lamp and blue light was shorter than that of other LEDs. The DPPH radical was high in blue light, green light, and yellow light except for red light, and the polyphenol was high in four kinds of LED sources. And ergosterol was the highest in the green light. Thus, the high-quality mushroom production of P. eryngii is possible to green light condition considering productivity and functional materials.

LED광원에 대한 큰느타리버섯의 생육특성, 에르고스테롤 및 항산화활성에 미치는 영향을 조사하였다. 원기형성기에 LED광원을 조사한 결과 청색광 및 적색광에서 원기가 형성되지 않았다. 초발이 이후 LED광원을 조사시 형광등과 청색광에서 다른 처리구 보다 갓의 크기는 커지며, 갓의 굵기가 굵어지는 경향이었다. 그러나 대의 길이는 형광등과 청색광에서 다른 처리구 보다 짧았다. 생육특성 중 상품수량은 청색광 및 녹색광에서 형광등과 대등하였다. DPPH는 청색광, 녹색광 및 주황색광에서 가장 높았고, 총폴리페놀함량은 LED 처리구 모두 형광등 처리구보다 높았으며, 에르고스테롤은 녹색광에서 가장 높았다. 이상의 결과 큰 느타리버섯의 고품질 버섯 생산을 위해서는 녹색광이 적합하였다.
