Abstract: 

Magnetic fields are environmental factors that effect on plants and other living creatures. In this study the effect of magnetic field on seed germination and seedling ontogenesis have been investigated. Dry and soaked vetch seeds (Vicia sativa L.) were treated by 100, 1700 and 3600 Gause (G) magnetic fields for 5, 10 and 20 minutes and then the seeds were transferred to MS tissue cultures. Rate and percentage of seed germination were measured in 3 replicated of 18 seeds. Growth of root, epicotyl, hypocotyl and number of lateral roots in 7th and 14th days after treatments and then fresh and dry weight of seedlings in 14th days were investigated. Results showed that rate and percentage of seed germination decreased in magnetic field treatment samples, compared to control samples but rate of germination of soaked seeds increased compared to dry seeds that exposed to magnetic field treatment. Seedlings growth and their fresh weight increased in magnetic field treatment samples compared to control sample. The samples exposed to 1700G magnetic field for 20 minutes in wet conditions had longest roots and epicotyls compared to control samples.
