To investigate the effects of combined exposure to extremely low frequency magnetic fields (ELF AC fields) and local geomagnetic field (DC field) on germination of hornwort seeds (Cryptotaenia japonica).
|Exposure 1: 3.5–14 Hz|
|Exposure 2: 7 Hz|
|Exposure 3: 7 Hz|
|magnetic flux density||50 µT||-||measured||-||Geomagmetic field|
|magnetic flux density||750 µT||effective value||measured||-||AC field orthogonal to the geomagnetic field|
|magnetic flux density||500 µT||effective value||measured||-||AC field orthogonal to the geomagnetic field|
The geomagnetic field in addition with a vertical AC field at 750 µT at 7 Hz or 500 µT at 14 Hz effectively promoted the germination of the seeds. The parallel AC field was more effective than the perpendicular field.
