Phenology is the annual cycle of plant development as influenced by seasonal variations. Dormancy and cold hardiness are two aspects of the annual cycle. In temperate plants, the development of cold hardiness results in the ability to withstand subfreezing winter temperatures. Cold hardiness is also a reflection of overall stress resistance. In addition to describing cold hardiness and its use as a tool for understanding seedling quality and making management decisions in the nursery and in the field, this paper describes four tests used to determine cold hardiness: the whole-plant freeze test, freeze-induced electrolyte leakage, chlorophyll fluorescence, and genetic markers.
