Effects of electrical stimulation on the yield of tuber of tiger's milk mushroom

• The growth rate of mycelium of the tiger's milk mushroom (Lignosus rhinocerotis) at intermediate development stage was successfully increased up to 16% by the application of corona discharge through multiple needles at a steady state voltage of 5 kV generated by a Van der Graff generator, for 5 h a day, for four weeks. The same method could enhance the yield of tuber up to 56%. Myco-chemical analysis on the tuber of the corona treated group did not show any significant variation in the total flavonoid content and metabolite chromatogram pattern in comparison with that of the control groups and the reference groups. The experiment shows that the enhancement of the harvest of tuber of the tiger's milk mushroom is much more significant than the growth rate improvement of the mycelium of the same type of mushroom, as it was reported previously.
