Response of static magnetic field to germination and seedling vigour of wheat seed

Seeds of wheat (Triticum aestivum L.) were exposed to static magnetic fields of different strength from 100-250 mT in steps of 50 mT for different duration from 1-4 hour in steps of 1 hour. Exposure to static magnetic field significantly increased shoot length, root length, germination index, germination rate, seedling dry weight, seedling vigour index and dehydrogenase enzyme activity of wheat seed over control whereas difference in seed germination was non-significant. Seed coat membrane integrity was significantly improved by magnetic field over control seeds. Different exposure duration did not significantly influence seed germination and seedling vigour of the seeds.
