Keywords: Cryoconservation | Tanacetum ulutavicum | Niedzwedzkia semiretschenskia | Rhaponticum carthamoides | defrosting temperature | seed humidity

The article considers the possibility of cryopreservation of seeds of several species of drug plants in Central Kazakhstan – Tanacetum ulutavicum, Niedzwedzkia semiretschenskia, Rhaponticum carthamoides. To increase the amount of viable seeds after liquid nitrogen freezing, we used different defrosting temperatures, deposited seeds with different moisture contents and used different containers for cryopreservation. Recommendations, concerning conditions of cryopreservation of seeds of these drug plant species were developed, basing on the obtained results.
