The growth of the trees in the boreal zone is based on the acclimation and adaptation of their annual cycle with the changes of the weather conditions during the four seasons. Winter damage would be one of the most difficult challenge for many different woody plants. To prevent the winter damage and obtain higher economic benefits, different preconditioning methods such as using winter storage to help the first-year seedlings over winter have been developed. However, appropriate preconditioning for the different progenies of the plus tree of forest seedlings within the same species, and different horticultural woody species and cultivars are not known well.
