Problems of Cryobiology and Cryomedicine| Резюме: | It has been established that temperature, storage period, humidity, rates of cooling and thawing significantly affect viability of frozen-thawed cuttings. The found permissible values of humidity, parameters, providing maximal viability of birch, black currant berry, raspberry, cherry cuttings are 32–40; 40–50; 37–40; 33–45% within the positive range of temperatures and 14–28, 30–40, 23, 37% within the negative range. Decrease of humidity results in plasmolysis, and exceeding does in intracellular crystal-formation. During application of different regimens of drying and cooling with the rate of 0.1°C/hr down to –20°C with further plunging into liquid nitrogen the viability of frozen-thawed cuttings of currant berry and birch made 100%, 88% for raspberry and 57% for cherry. |
