Ice nucleation activity in biological materials with examples from antarctic plants.

Type of article: Article

Summary

First nucleation temperatures varied from -4.1 deg C (4 species of lichens) to -5.1 and -5.4 deg C (7 moss species and 8 species of higher plants respectively). At -7 deg C the mean numbers of nuclei per gram were lichens, mosses, and flowering plants and ranged from 257,000 to 16,220 nuclei per gram. It is crucial that procedures used in ice nucleator activity experiments be standardised to enable valid comparison between datasets and different studies to be made.
