The Effect of Magnetic Field on Three Different Varieties of Soybean Seed

In this study, 150 seeds from each of three soybean varieties (30 seeds for each application) have been passed through  3,8-4,8 mT magnetic flux density of the magnetic field 0, 1, 3, 9 and 15 times at a magnetic height of  0,055 m in order to determine the most suitable magnetic field strength for Defiance, General and Iraquous soybean varieties. Three different soybean seed varieties passed through magnetic field were germinated in petri dishes at 25°C on moist filter papers. The root lengths and germination percentages of the varieties were measured by making observations at the end of 24th, 48th, 72nd and 96th hours to determine the most suitable magnetic field strength. As a result, an increase was detected in the germination percentage and root length of D1(Defiance; 1 times pass through magnetic field)and D9(Defiance;9 times pass through magnetic field ) applications of the Defiance at the end of the 72nd and 96th hours compared to the control(D0,G0,I0), and also an increase was observed in the G1(General; 1 times pass through magnetic field) and G9(General; 9 times pass through magnetic field) applications of the General; whereas an increase was observed only in the germination percentage in the I3(Iraquous; 3 times pass through magnetic field) and I9 (Iraquous; 9 times pass through magnetic field) applications of Iraquous. No increase was detected for the root length in the I3 at the end of the 96th hours.
