| Sweetgum is a North and Central American tree species well known for the healing gum since the times of the Aztec civilization. In the southern United States, this is the most widely planted broadleaf species for wood production. It grows well on a variety of site conditions, including on alluvial soil prone to flooding. As a result of the wide natural distribution, it shows important variations in phenology and growth traits. The more northern provenances tend to shut down growth processes much earlier and resume them later than the southern sources. These variations reflect directly on the growth patterns among seed sources. Experiments in several sites have demonstrated its potential value for wood production in small wood lots in the South and... |
