Cryopreservation of suspended cells of selected Gentiana
Languages of publication
Cryopreservation is recognised as the most efficient method of plant genome preservation and embryogenic potential of plant in vitro cultures with non-changed status. Because of the risk of biological degradation of tissue during freezing treatment and it various sensibility on the chilling stress, the individual treatment with cryoprotectance and parameters of the temperature decreasing is highly required. In this presentation, following subjects will be discussed: 1) description of suspension cultures of various gentians, 2) cell pretreatments for surviving the stress of low temperature, 3) rearrangement of cell cytoplasm because of high sucrose concentrations, 4) the role of sucrose in the development of freezing tolerance and surviving of gentaiana suspensions, 5) the effect of strong plasmolysis induced by 3 M glucose.
