Effect of Grafted Roots of Stumps on the Growth of a Thinned Red Pine Plantation
Casual observations made several years after the thinning of red pine plantations disclosed that some stumps undergo decay and can be easily removed by hand, whereas other stumps remain perfectly sound. Subsequent examinations revealed that the roots of sound stumps are grafted to roots of residual trees while the stumps with ungrafted roots succumbed to fungi (5). The grafting of tree roots has received attention of several investigators (1,2,3,4), and redistribution of nutrients, as well as eradicants among trees with interlocked root systems, is well established. Our investigation was concerned with the effect of grafted roots of stumps on the growth of residual trees of a thinned red pine plantation. The study was conducted in the Nekoosa Papers, Inc. Industrial Forest, located in Adams County of central Wisconsin.
