Root, Shoot, and Leaf Area Growth Potentials of Northern Red Oak Planting Stock
Root, shoot, and leaf growth of four classes of northern red oak (Quercus rubra L.) planting stock were observed in root observation chambers in the greenhouse. The four classes of stock were container-grown, large 1-0 bare-root, small 1-0 bare-root, and 1-1 bare-root. Shoots on half of each class of stock were clipped 15 cm above the root collar prior to initiation of the 11-week study. By the end of the study, unclipped container-grown stock produced, on the average, more shoot growth, leaf area, and root elongation than the other treatment combinations. A regression model relating cumulative root elongation to leaf area, initial shoot volume index of the tree, time, type of planting stock, and clipping treatment explained 78 percent of the variability in cumulative root elongation. The results suggest potential growth advantages associated with containerization of red oak seedlings. Forest Sci. 30:1017-1026.
