Thermodynamic analysis of the mechanism of deep supercooling of tissue water in winter-hardy plants.

Author(s) : FANYI S., WENJI L., RONGFU G., et al.

Type of article: Article

Summary

The temperature at which ice grows through narrow, hydrophilic capillaries, is depressed and the nucleation temperature near a hydrophilic surface varies with the size, geometry and the properties of a particle. The authors show how these two effects are additive for the water that freezes on the wall of a capillary without the presence of pre-existing ice. The combined effect is a substantial lowering of nucleation temperature that could, if this analysis is correct, have important cryobiological consequences.
