Pollen germination of Norway spruce and Scots pine is stimulated by low doses of x‐rays and radar (densities 2,7–6 mW/m 2 ) when exposed for one minute. Longer exposition inhibited germination generally, but the less vital pollen seemed to be destroyed first. Radiowaves with λ= 3m and electrostatic fields (frequency 50 Hz; field intensities between 2 kV/m and 10 kV/m) did not show effects on germinating pollen. Pollen tubes were longer when germinated in darkness.
