The purpose of work is to research influence of freezing and thawing on the germination of pine and spruce seeds. Test of different variants of freezing and thawing of coniferous seeds showed that good results of germination (excess over the control of 4–5 %) for spruce seeds was in the variant with freezing to –86 °C at a rate of 4 °C per minute with a detent for 30 min and thawing to +20 °C at a rate of 4 °C per minute, for pine seeds – in the variant with freezing to –2 °C at a rate of 4 °C per minute with a detent for 5 minutes and subsequently freeze to –98,3 °C at a rate of 4 °C per minute with detent 30,9 min and thawing to + 20 °C at a rate of 4 °C per minute.
