Hybrid poplar grows poorly on acid spoil banks at high elevations in West Virginia

Abstract

In the early 1950s, a region-wide series of hybrid poplar clonal tests was begun in the Northeast to evaluate the performance of 50 selected clones under a variety of site and climatic conditions. The basic test unit was a block of 50 randomized plots-1 plot for each of the 50 clones. In each plot, 16 cuttings were planted at 4-foot spacing.
