    Cold acclimation is a process whereby plants increase their freezing tolerance after exposure to a short period of low but non-freezing cold temperatures. Whereas cold acclimation can be induced at 12 °C, vernalization requires lower temperatures, suggesting that the cold acclimation and vernalization pathways are independent ( Bond et al., 2011 ).
