Cryopreservation (storage in liquid nitrogen, –196°C) is a technique that ensures safe, long−term conservation of plant species with recalcitrant seeds, vegetatively propagated species and biotechnology products such as somatic embryos, cell lines and genetically transformed material. The aim of cryostorage is to keep plant tissue in a safe way, which does not cause changes during storage at neither phenotypic, cytological and histological, biochemical, genetic nor epigenetic level. Therefore, before cryostorage will be applied for long−term preservation it should be thoroughly assess if it does not cause any injuries in plant material.
