Abstract
Cryotolerance of seeds has been studied in 103 plant species of 33 families from five regions of the Russian Far East. In 89.1% of these species, seed viability has not decreased in the course of cryogenic storage. Six species have shown interpopulation variation in the seed response to extremely low temperature (−196°C). Freezing in liquid nitrogen, which results in deep anabiosis, can be used as a means for long-term seed storage. A preliminary assessment of genetic diversity at the population level provides for the maximum possible mobilization of the species gene pool. The results of this study contribute to the development of a scientific basis for creating a seed bank of the Far Eastern flora with the purpose to conserve and restore biological resources of the region.
