Abstract
A plant's cold hardiness, or its tolerance to freezing temperatures, is genetically determined. However, environmental conditions and cultural practices are factors that also influence a plant's cold hardiness. The seasonal change in resistance to freezing temperatures occurs in response to environmental cues in plants that have the genetic capacity for cold hardiness. The three components of cold hardiness are: 1. cold acclimation; 2. ultimate or maximum mid-winter hardiness; 3. deacclimation. Improper timing or insufficient development of any one of these components may limit plant survival.In hardy trees and shrubs, cold acclimation is generally considered to be a two-stage process. The first stage is initiated by shorter day lengths later in the growing season, resulting in partial hardiness. The second stage is initiated by subfreezing temperatures and results in ultimate or maximum cold hardiness.
