Effects Of Electromagnetic Fields On Seed Germination In Urtica Dioica L

Abstract The study of electromagnetic fields on plants growth and other living beings are one of the most important subjects which attract manyresearchers attention therein. various plants react against electromagnetic fields with different levels of intensities. In this research the effects of electromagnetic fields on germination of seeds property of Urtica dioicaL. were studied .Seeds of this plant were put under electromagnetic field by 0.8 and 1.6mT for duration of 51020 minutes. In addition this test was performed at first on dry seeds and after 48 hours on wet seeds. Under theseconditions the velocity of germination and percentage of treated seeds were increased againstcontrol. Except on item in which germination percentage was decreased against control about wet seeds which put under electromagnetic field by 0.8 for5 20 minutes duration. Among treated samples electromagnetic field by 0.8mT in 5 minutes duration and 1.6mT in 10 minutes duration in dry seeds andalso for 5 minutes duration in wet seeds showed the fastest germination among treated.
