The effect of electrostatic field on soybean seed germination parameters

Abstract

The aim of this study was to examine the influence of electrostatic fields on seed vigor (VI), mean rate of germination (MGR) and coefficient of velocity of germination (CVG) of five soybean genotypes. Testing was conducted at the Novi Sad Institute of Field and Vegetable Crops on the seeds of five soybean varieties: Sava, NS 2024, NS 1347, NS 3127, and NS Blackstar. The seeds were exposed to different voltages of direct current (DC): 0 V (control), 3 V, 6 V and 9 V, to which the seeds were exposed for 0 min (control), 1 min and 3 min. The application of DC can be a suitable method for improving VI, MGR and CVG. In addition, the results indicate that it is necessary to adjust the DC treatment (voltage and duration of exposure of seeds) to a particular genotype, since inadequate treatments may deteriorate the quality of seeds.
