Wood specific gravity in a rangewide sample of loblolly pine (Pinus taeda L.) grown in a common environment in southwest Arkansas differed from reported values of trees samples in situ. Differences were greatest at the extremes of the species range. The primary objectives of this study were to determine whether geographic trends in wood-specific gravity exist when trees of various seed sources are grown in a common environment, whether they are similar to previously reported trends for loblolly pine in situ, and whether trees from the North Carolina provenances exceed those from Arkansas on a weight as well as a volume basis when grown in Arkansas. Secondary objectives were to determine if a relationship exists between stand density and wood-specific gravity and between tree growth and specific gravity in the seed source study.
