Poor Vertical Root Development May Contribute to Suppression in a Red Pine Plantation

Initial stem and root growth of trees that became suppressed within 30 years in a red pine (Pinus resinosa Ait.) plantation were poorer than those that became codominants. Stem and horizontal root extension improved later but then declined. The likelihood of suppression may have been initiated at or before planting. Inadequate development, perhaps through chance, of vertical roots that could tap moisture-holding layers at the 2.8 m depth in the well-drained loamy sand soil contributed to the suppression process.
