Description: Two shortleaf pine (Pinus echinata Mill.) provenance tests established by the USDA Forest Service North Central Research Station as part of the South-wide Southern Pine Seed Source Study were examined to determine the most suitable seed sources for planting in Missouri. Each test comprised seven different provenances from six to seven states in the natural shortleaf pine distribution. Significant provenance differences in survival and height growth were found in both tests and a strong north-south trend was observed. More northernly sources (New Jersey and Tennessee provenances) had the best survival and greatest height growth while southern sources (Georgia and Louisiana) had the poorest survival and lowest height growth. Regression estimates of slope indicate that New Jersey and Tennessee provenances have the highest relative growth rates. Both survival and height were highly correlated with latitude at the seed source. Results from this study suggest that the best seed sources for planting in central Missouri are not those from Arkansas, as current practice suggests, but instead are in states in the northern portion of the natural shortleaf pine distribution.
