The effects of Norway spruce ( Picea abies ) seed treatment with cold plasma (CP), vacuum, and electromagnetic field (EMF) on germination and seedling growth are studied. CP treatments negatively affected germination ‘in vitro’, but for germination in cassettes CP (7 min) and EMF (5 min) significantly increased the germination yield. All treatments increase the germination rate in cassettes except CP (7 min) treatment having a negative effect. Seed treatment with CP and EMF increases the number of paramagnetic centers in dry seeds and modulate H 2 O 2 production in germinating seeds. After the second vegetation season seedlings grown from CP (5 min) and CP (7 min) treated seeds, characterized by negative effects on either the germination rate or yield, have 50–60% larger height and 40–50% increased branching in comparison to the control seedlings.
