Results from a preliminary research on the pre-sowing electromagnetic treatment of rape seeds

摘要

A possibility has been established to stimulate the sowing quality of rapeseeds through subjecting them to a pre-sowing treatment in an electromagnetic or electrostatic field. It has been confirmed that, after a period of rest of the seeds (up to 7 days) between treatment and sowing, a beneficial effect of the pre-sowing electric impact is observed – up to 18% increase in the length of roots and up to 22% increase of the germs. It has been determined that 21 days after the said treatment, the effect has already become suppressive. The application of increased voltage values (12kV for the electromagnetic treatment and 6 kV for the electrostatic one) has resulted in no statistically significant influence on the monitored parameters – length of roots and germs. The pre-sowing electric impact helps to obtain better nourished seedling roots and germs which have up to 25% higher mass than those of the reference seeds.
