Growth and Development of Shoot and Root Pruned Yellow-Poplar Seedlings on Two Sites

Yellow-poplar (Liriodendron tulipifera L.), one of our major hardwood species, attains its greatest growth on well-drained bottomlands and coves, but these sites also support the greatest amount of competing vegetation. Several studies (2, 4, 8) have shown that yellow-poplar does not do well with overstory competition. In attempting to improve survival and competitive ability of yellow-poplar planted seedlings, Sluder (1964) found that root pruning increased root weight and fibrosity but not survival, and Thor (1965) found an increase in root branching with no effect on survival. However, Linstrom, et al. (1955) noted an increase in survival when seedling roots were pruned to 10 inches. A study at Clemson University (Bruner,' unpublished), on the other hand, showed a significant reduction in survival with increasing severity of root pruning. None of these workers found a correlation between shoot pruning and survival.
