Geographic Variation of Sweetgum

A range-wide sweetgum (Liquidambar styraciflua) provenance study was established in 1966 to assess the variation in survival, growth and quality traits associated with differences among trees in stands, among stands, and among geographic sources. Seed were collected from five trees from each of two stands from each of 14 sources across the south and southeastern United States. Outplantings were established in each of the 14 seed source areas.
