Abstract

A edible mushroom, Hypsizygus marmoreus is commercially cultivated. However, the researches of cultivation and physiological characteristics were not conducted in Korea. In this study, we conducted on artificial cultivation of H. marmoreus and elucidated the effect of light on the mycelial growth and fruit body development using LED light sources with different wavelength; blue (peak wave length 460nm), green(peak wave length 530nm), yellow(peak wave length 590nm), red(peak wave length 630nm), and white as positive control. Mycelial growth of H. marmoreus strains were inhibited about 30~40% in inhibition ratio under the illumination with blue, green, yellow LED light. However, red LED light was not inhibited. Elongation of stipe was effective under the long wave length such as yellow and red light. Abnormal fruit body was produced under the long wavelength and dark. However, development of pileus was effective under the short wavelength such as green and blue light. Also, as a result of cultivation with mixed light for high quality and harvest, many effective numbers and yields of fruiting bodies were obtained in the mixed treatment of blue and white light, and pileus developed well.

LED 광원이 느티만가닥버섯 재배에 미치는 영향을 알기 위하여 6종의 파장이 다른 NUV(wave length 405nm), blue(wave length 460nm), green(wave length 530nm), yellow(wave length 590 nm), red(wave length 630nm), white(wave length 6500K) 광을 조사하면서 균사 생장 및 자실체 생육과 수량을 조사하였다. 1. 느티만가닥버섯균의 균사 생장에는 광이 필요하지 않지만, red 광 처리구에서 암조건과 비슷한 균사 생장을 보였다. 그러나 blue, green, yellow 광 처리구에서는 암배양보다 약 30~40%의 균사 생장 저해를 보였다. 2. LED 광이 느티만가닥버섯의 자실체 생육에 미치는 영향을 조사한 결과, 암조건에서는 자실체 발달이 안 되는 경우도 있으므로, 느티만가닥버섯의 자실체 생육에는 광 조사가 꼭 필요하다. 단파장인 blue와 green광, 복합광인 white을 조사한 처리구에서 자실체 갓과 대 발달이 안정적이면서 수량이 우수하였다. 장파장인 red 와 yellow 광 처리구에서는 갓 발달과 색택이 불량하고, 대는 길고 꼬임 등의 기형을 보였다. 3. 단일광 조사만으로는 우수한 품질의 버섯을 안정적으로 생산하기 어렵고, 각 생육 단계마다 효과가 있는 광을 조사하는 것도 어렵다. blue와 green, white, red 광을 조합하여 생육 기간 동안 혼합광을 조사하여 갓과 대의 균일성 및 갓 색택, 수량을 분석한 결과, 가장 이상적인 LED 광 조합은 blue와 white 광이었다.
