In boreal forests with cold winters, evergreen coniferous species must develop adequate freezing tolerance to survive in the severe climate. Such species show autumn cold hardening as a seasonal acclimation response. It is important that the cold hardening occurs at a suitable time in each local climate,but there is a phenological trade-off between later hardening,which lengthens the active growth period,and earlier hardening,which avoids frost damage. Various kinds of environmental signals that vary locally might regulate hardening in plants. A modeling approach can extend our knowledge of the relationship between temperature- related signals and plants’ ontogenetic development of autumn cold hardiness, thereby enabling us to quantify intraspecific variations in freezing tolerance.
