Glass transition and heat capacity behaviors of plant vitrification solutions

Popis výsledku v původním jazyce

Differential scanning calorimetry (DSC) was employed to investigate the vitrification and annealing behaviors of the most commonly used plant vitrification solutions (PVS). These solutions are employed to protect plant tissues toward ice formation and freeze injury, and help to the vitrification of these tissues, by globally reducing the intracellular fluids mobility. Glass transition temperatures (TG) and heat capacity increments (DCp) were determined for five solutions PVS1, PVS2, PVS2 mod, PVS3 and PVS3 mod, with different composition, and a range of cooling and warming rates was employed. Glass transitions showed clear and consistent temperature differences within vitrification solutions, which could be related to composition and water content. Roughly, two sets of TG values were obtained, those for PVS1 and PVS2, at -112 °C and -114 °C, respectively, and those for PVS3, at -90 °C. The observed TG and DCp, unexpectedly, did not significantly change within a wide range of cooling ra
