Problems of Cryobiology and Cryomedicine| Zusammenfassung: | Tolerance of seeds of plants from the family Cupressaceae (Cypress) Chamaecyparis lawsoniana (Lawson's cypress), Cryptomeria japonica (Japanese cypress), Platycladus orientalis (Oriental broadleaf) and Pinaceae (Pine) Larix kaempferi (Kaempfer's larch), Pseudotsuga menziesii (Menzies' pseudotsuga), Tsuga сanadensis (Canadian hemlock), which according to the International Classification are less spread plants, to storage conditions in liquid nitrogen were investigated for the first time. The results of scientific research into the preservation of seeds in liquid nitrogen, as a source of genetic information, confirmed that the investigated seeds of plants introduced in Western Ukraine retained their viability after storage. Soil germination of cryopreserved seeds increased compared to the control variant on 0.7% for C. japonica, 7.4% for L. kaempferi or decreased in T. canadensis by 2%. The growth and development of the control seedlings do not differ from seedlings obtained from cryopreserved seeds.
