Available in PDF, EPUB and Kindle. Book excerpt: High-voltage electrical stimulation is effective for promotion of fruit-body development in mushroom cultivation. The high voltage applying to cultivation bed of mushroom generates intense electric field inside the bed substrate. The intense electric field accelerates the hypha move owing to the electrostatic force. As a result, some parts of hyphae are cut and scratched. The cutting and scratching of hypha work as stimulation for promotion of the fruit-body development. The promotion effect of high-voltage stimulation to sawdust-based substrate of L. and natural logs hosting Lentinula edodes, Pholiota microspora and Hypholoma lateritium are confirmed through the experiment in the cultivation field. The fruit-body formation of mushrooms increases 1.3-2.0 times in terms of the total weight. The accumulated yield of L. edodes for four cultivation seasons is improved from 160 to 320 g by applying high voltage of 50 or 100 kV. However, the yield decreases from 320 to 240 g upon increasing applied voltage from 100 to 130 kV. The yield of the other types of mushrooms shows tendencies similar to those of L. edodes by applying high voltage. An optimal voltage exists for efficient fruiting body induction.
