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 sampled in situ. Differences were greatest at the extremes of the species range. In the common environment trees from western and northeastern sources produced the highest specific gravities; northeastern trees produced the highest dry weight per hectare yields but they were not significantly greater than yields of trees from east coast and northwest sources. On an individual tree basis, specific gravity was significantly negatively correlated with height, diameter, and volume, although the r values were small; 0.272, 0.090, and 0.129, respectively. Provenance region correlations between specific gravity and growth and stand density parameters were generally weak to negligible. For. Sci. 36(4):1133-1145.
