Study of the effect of static magnetic field on seed germination of Physostegia virginiana alba (L.) Benth.

Abstract

The article presents the results of studing of the influence of static magnetic field on seed germination of Physostegia virginiana alba (L.) Benth (Fizostehiya Virginia). Stimulating effect of static magnetic field strength by 5.0–60.0 Еrsted towards germination of the plant was found. At an early stage (fourth and fifth days after seeding) germination of Physostegia virginiana alba (L.) Benth. depended on the duration of static magnetic field and on its strength in range of 5 to 60 Е. At the final stage (tenth day), this relationship was very weak. The stimulation effects upon seed germination were found at short-term influence of static magnetic field on the plant during all ten days of the experiment (exposure of seeds within 0.5–3.0 hours), with the exception of three-hour magnetic field strength at 60.0 Е. The first germinated seeds were found as soon as on the fourth day of the experiment. For a long-term action (duration 6.0 and 18.0 h) of a static magnetic field on seeds of Physostegia virginiana alba (L.) Benth., stimulation of seed germination was observed only starting from the seven day after seeding.
