ABSTRACT Corona discharge from multiple needles at an electrical potential of 5 kV generated by a Van de Graff generator increased the growth rate of the mycelium of tiger’s milk mushroom by 10.3% at the end of the first eight days. A similar growth rate enhancement was observed for the next eight days as well. Mycelium of tiger’s milk mushroom was cultured on agar media in Petri dish for five days prior to the exposure to various forms of electrical stimulations. The direct current injection (1.1–1.3 A) to the growing medium, application of an electric potential to the growing environment at low strength (30 V) and high strength (5 kV) with single and multiple needles showed varying degrees of success. This suggests that the mycelium of tiger’s milk mushroom could positively be stimulated by specific electrical stimulation techniques with selected parameters. This will pave the way to a highly beneficial growth enhancement technique that can be up-scaled to apply in mass production of mushroom.

电刺激对 lignosus rhinocerus (cooke) ryvarden 菌丝生长的影响

摘要 在前八天结束时，由范德格拉夫发电机产生的 5 kV 电位下的多针电晕放电使虎乳菇菌丝体的生长速度增加了 10.3%。在接下来的八天中也观察到类似的增长率提高。在暴露于各种形式的电刺激之前，将虎乳芝菌丝体在培养皿中的琼脂培养基上培养五天。向生长介质中注入直流电 (1.1-1.3 A)，使用单针和多针在低强度 (30 V) 和高强度 (5 kV) 下向生长环境施加电位显示出不同程度的成功。这表明，具有选定参数的特定电刺激技术可以积极刺激虎乳芝菌丝体。这将为一种非常有益的生长促进技术铺平道路，该技术可以扩大规模以应用于蘑菇的大规模生产。
