研究目的(著者による)

To study the effects of an extremely low frequency magnetic field on mushroom spawn growth and yield.

詳細情報

Most species of Pleurotus are edible. Especially, the oyster mushroom (Pleurotus ostreatus) is widely cultivated. An increasing yield through magnetic fields could be economically interesting.
The mycelium was exposed at different magnetic flux densities (5, 15, 25 and 100 mT) and for different time periods (2, 5 and 15 minutes).

研究の主なアウトカム(著者による)

Exposure of the mycelium resulted in significantly increased numbers of pin heads and mature mushrooms as well as wet and dry masses in comparison to the control group. Especially, the combinations 5 mT for 15 minutes, 15 mT for 15 minutes, 25 mT for 15 minutes and 100 mT for 2 minutes showed superior effects. No significant difference was found in the duration until pin heads appeared between the exposure groups and the control group.
The authors conclude that exposure of mushroom mycelium to extremely low frequency magnetic fields could be used practically to obtain higher yields.
