Impacts of root frost damage in the nursery on post-planting performance of containerized white spruce, black spruce and jack pine seedlings

Summary

Published in CryoLetters 21: 191

Damage to roots from frosts is a serious problem for the nursery production of containerized tree seedlings in northern climates. Knowledge of the consequences of different levels of root damage on post-planting performance is essential to the proper planning of reforestation activities. Consequently, the effects of different levels of root damage due to frost on the post-planting performance of containerized white spruce (Picea glauca [Moench] Voss), black spruce (Picea mariana [Mill.] B.S.P.) and jack pine (Pinus banksiana Lamb.) seedlings were evaluated on a mesic and on a dry site in Québec, Canada.
