Abstract
Effect of electric impulse was investigated on fruit body formation of Lentinula edodes in the sawdust-based substrate. Electric impulse of 15 kV was directly charged to the substrate at 3 different fruiting phases, 90- (1st flush), 130- (2nd flush), and 170- (3rd flush) day cultures, respectively. Ergosterol contents and water conditions of the substrate were examined at the 3 phases. The electric impulse was effective in fruit body formation of 4 strains for 3 different fruiting types, which occurred year-round, from autumn to winter. The effect of the electric impulse was more prominent as culture age proceeded (2nd and 3rd flushes).
