Geographic and seasonal variation in coldhardiness of whitebark pine

Bower, A. D. and Aitken, S. N. Canadian Journal of Forest Research 36(7):1842-1850. 2006.

Artificial freeze-testing utilizing the electrolyte-leakage method was used to test the cold hardiness of 2-year-old whitebark pine (Pious albicaulis Engelm.) seedlings growing in a common garden setting across all seasons was used to determine the annual pattern of cold hardiness, and more intensive sampling in the fall and spring was used to assess genetic variation in cold injury among geographic regions spanning the range of the species.
