In recent decades, research on the effects of physical fields– particularly electric and magnetic– on biological processes in plants has developed significantly. These fields can influence seed germination, cellular activity, and the subsequent development of seedlings, offering innovative perspectives in agriculture and forestry. The present study evaluated the impact of electric and magnetic fields on spruce seeds, with the aim of improving germination rates and seedling growth. For the electric field, three voltages (10V, 30V, 50V) and two exposure times (15 and 35 minutes) were tested. The most effective combination was 10V for 35 minutes, while the 50V- 15 minutes’ variant had negative effects. The highest seedling height was obtained at 10V 15minutes. In the case of the magnetic field, the seeds were exposed to three different times intervals- 10, 20, and 30 minutes- at an intensity of 0.22 × 10⁻³ T. A 20-minutes exposure resulted in the highest germination rate and produced seedlings with significantly greater heights compared to the control and other variants. The results demonstrate the positive effect of using physical fields as an ecological and efficient method for stimulating germination and plant development, offering valuable applications in forest regeneration and the production of high-quality seedlings.
