This study was aimed to reduce the period of bed log through the protection of harmful fungi and to investigate the effects of physiologically activating substance on the yield increase of Lentinus edodes. Extracts of Allium fistulosm, Hordeum vulagare var. hexastichon, Lentinus edodes. Daucus carota var. sativa, and Citrus junos were used as a physiologically activating substances. The degree of mycelial growth tested by color change after Benzene - azo - ${\alpha}$ - naphthylamine. One percent extract of Album fistulosm was most highly effective as a physiologically activating substance on mycelial biomass growth of Lentinus edodes. Best effects of application of physiologically activating substance was observed in Quercus variabilis bed logs. These results suggested that supplement with physiologically activating substance to the bed log would be beneficial for the production of Lentinus edodes.
