We aim to elucidate suitable color of light during development of fruit body in Pleurotus eryngii. The four color of LED(Light Emitting Diode), blue LED(475nm), green LED(525nm), yellowed LED(590nm), and red LED(660nm), were irradiated for formation of fruit body after mycelia growth. First, as effect of color of LED at all growth stage, the morphological properties of fruit body in fluorescent lamp and blue LED irradiation were showed thicker and longer pileus than those in other color LED irradiation. The commercial yields in blue and green LED treatment were similar to control(Fluorescent lamp). Second, as effect of color of LED by light irradiation time, we could obtain the highest commercial yields at the green LED continuous radiation, 1/1 and 1/2(lighting/lighting-out, hours). And we could obtain the highest number of available stipes and biological efficiency at the 1/1(lighting/lighting-out, hours). The ergosterol was the highest under the green LED continuous radiation.
