Root Regeneration of Transplanted Trees in Relation to the Status of Carbohydrate Levels and Root Invading Fungi

The natural root distributions of 7 species of shade trees (Norway, red and sugar maple, green ash, redbud, ginkgo and pin oak), growing under nursery conditions were characterized. In general, the vertical distribution of the major roots showed the greatest development at the soil depth of 13-38 cm, with limited growth in the top 12 cm, and decreasing development at depths below 38 cm. The north quadrant of the root systems of these trees was more developed than any other quadrant. Fine roots that develop in rather shallow soil appear to constitute a large portion of the early root system that develops the first year after transplanting. Regenerated roots originate primarily at the severed ends of the roots cut during transplanting.
