Abstract:

This study was conducted at the seed quality analysis laboratory of the Faculty of Agricultural Sciences, National University of Assunção. Sunflower seeds (Helianthus annus) L. were exposed to stationary magnetic fields with different intensities and exposure times aiming to evaluate the influence of static magnetic fields on seed germination and vigor. The variables analyzed were germination, shoot length and root length. The results showed a positive effect on shoot length when seeds were magnetized. The results of the magnetic treatment at an intensity of 40 mT and 72 hours of exposure were superiorto the control in relation to the variables shoot and root length. We can conclude thatmagnetism at an intensity of 40 mT for 72 hours promotes the growth of sunflower seedlings.
