Considerable interest is currently being expressed in the production of container-grown stock. The container-grown seedling is a comparatively new approach to regeneration silviculture and has only been under intensive study since the early 1960's. At present there are several types of containers, the one most commonly used in eastern Canada being the plastic tube, developed by the Ontario Department of Lands and Forests. This is a 3 inch-long, open-ended tybe, 3/16 inches in diameter, made of high-impact styrene. In spite of the present large scale production of seedlings in these tubes, little quantitative evidence is available on the factors which are likely to affect tubeling survival and growth. A trial was established to obtain such information for black spruce (Picea mariana (Mill.) BSP.), jack pine (Pinus banksiana Lamb.) and scots pine (Pinus sylvestris Linn.) tubelings when raised and planted-out under Quebec conditions.
