Cold hardening and acclimatization of coniferous seedlings are discussed and reviewed in relation to plantation success. A reduction in temperature and photo-period at the end of the production period is the best acclimatization treatment for cold stress. Moisture stress, deprivation of nitrogen and low temperature in the dark did not improve hardening of black spruce (Picea mariana [Mill] B.S.P.) material. Preliminary field observations indicate that acclimatized seedlings have a superior survival rate.
