Cold hardiness mechanisms and modeling: existing approaches and future avenues

open access: yesNew Phytologist, Volume 249, Issue 6, Page 2668-2682, March 2026.
Summary Cold hardiness models are useful tools to predict cold damage in plants, such as those produced by unseasonal temperature cycles or by increased cold exposure. Although development of these models started about five decades ago, their applications remain limited.
