Morphological effects of magnetic field on New Guinea impatiens explants

In the present study, the effects of an external magnetic field (MF) on the morphology of New Guinea impatiens (Impatiens × hawkeri W. Bull) explants were investigated under controlled (in vitro) conditions. To investigate the sensitivity of plants to magnetic flux density, plants were exposed to a homogeneous MF (0, 75, 150, and 200 mT) for 10 and 60 min day^‑1 for seven days. The highest fresh weight and dry weight were observed in 150 and 200 mT in 60 min day^‑1. Besides, the highest shoot induction time and growth rate of root hairs were observed in 200 mT and 60 min. Notably, the most significant difference in growth was observed in samples treated by 200 mT magnetic flux density for 60 min.
