Yellow-Popular Height Growth Affected by Seed Source
According to observations at the Santee Experimental Forest, near Charleston, South Carolina, seed source has a striking influence on early height growth of yellow-poplar (Liriodendron tulipifera L.). A small experimental planting in this flatwoods location showed the trees from a mountain seed source (western North Carolina) had an average height of 4.4 feet early in the third growing season. In contrast, those from Coastal Plain seed (eastern North Carolina) averaged 7.9 feet in height, or almost twice as tall (fig. 1).
