Jack Pine Seedlings Grown in Quebec Tubes and Other Containers

A preliminary study of container-grown jack pine (Pinus banksiana Lamb.) seedlings showed that root spiralling was a problem in Quebec tubes (Fig. 1A). Seedling quality was highest in styroblock-8 and lower, but similar, in tubes and Rootrainer "Hillsons" at 4, 6 and 10 months (Fig. 1B). In a second study, jack pine seedlings grown 4-6 months in several modifications of the Quebec tube were compared with those grown in regular tubes and styroblock-8s.
