In previous studies, we selected green LED(light emitting diodes) for suitable wavelength of light by higher commercial yields and lower ratio of abnormal fruit body in Lentinula edodes. In this study, we aim to select efficient irradiation intensity of green LED. Stronger irradiation intensity of green LED resulted in more polyphenol contents of fruit body. In four level of irradiation intensity, 5, 10, 15, 20umol/m2/sec there was no big difference in commercial yields and characteristics of fruit body. In addition, Lower irradiation intensity resulted in smaller amount of electircity used. In conclusion, we selected 5umol/m2/sec for suitable irradiation intensity in Lentinula edodes with sawdust substrate cultivation.
