Biomorphology, germination and cryopreservation of some ornamental shrub seeds in the Russian Far East

Biomorphological, metric characteristics, germination conditions are studied, the response reaction of 13 shrub, undershrub and dwarf semishrub species to ultralow temperature (-196°С) influence in order to evaluate the possibility of their long-term storage for creating the seed bank is revealed. For most species cryopreservation did not have the negative effect; the seeds retained their viability at the initial level.
