Three separate experiments on seeds of Norway spruce, European larch, and Scots pine were performed. The effect of six various doses (5, 10, 15, 20, 25, and 30 Gy) was examined, whereby the laboratory germination rate, soil germination rate and health of seedlings were investigated. Generally lower germination rates as well as deteriorated health of seedling were found in irradiated seedlings as compared with the control (non-irradiated sample), however, for low radiation doses of 5 and 10 Gy, the differences were non-significant. Considerable inhibition effect was manifested for higher radiation doses of 25 and 30 Gy
