The growth of containerized jack pine (Pinus banksiana Lamb.) seedlings three years after outplanting was still influenced by the original container configuration. Paper material from paperpots still surrounded root systems and root deformities caused by container confinement were still evident. Three types of root deformities were noted: spiraling, container compression, and kinked roots. Spiraling and container compression were most severe with seedlings grown in the BC/CFS Styro 2 and the 408 paperpot. The use of a rib-type container should eliminate spiraling. Seedling growth was directly related to the volume of the original containers, but could not be correlated with deformities.
