Influence of 50 Hz magnetic field on growth of mushroom species: shitake (Lentinus edodes) and oyster (pleurotus astreatus)

摘要

Investigation on effects of electromagnetic fields on different aspects of biological systems had been done by much research. Our present study which has been carried out under the joint research between the lab. of High-voltage and High-currentEngineering and Lab. of Microbiology of Institut Teknologi Bandung investigates influence of 50 Hz magnetic field on the growth of several species of mushroom. In this study, we observed growth of mushroom, from spora up to fully ripped stages, undermagnetic field exposure of different intensity from 0,1 mT to 1,7 mT. During exposure the room condition was held constant at temperature of 20°C and 95% humidity. We noted that some parameters such as : mushroom growth velocity, shape, dimension,quantity, color and period of mushroom ovary are significantly influenced by magnetic energy absorbed.
