Longleaf pine from six seed sources was grown in Virginia and examined for specific gravity differences after eight growing seasons. One seed source from Florida had significantly lower specific gravity than other sources tested, and was less frost resistant. Although data indicated a racial difference in specific gravity, a valid conclusion cannot be made in view of a confounding with incompatible environment. It is possible that differences in frost resistance existing in this plantation may have caused, or were associated with, specific gravity differences observed in the study. When the Florida seed source was omitted from the analysis of variance, there was no significant difference in specific gravity of five seed sources.

  • The Journal of Forestry is the most widely circulated scholarly forestry journal in the world. In print since 1902, the Journal has received several national awards for excellence. The mission of the Journal of Forestry is to advance the profession of forestry by keeping forest management professionals informed about significant developments and ideas in the many facets of forestry: economics, education and communication, entomology and pathology, fire, forest ecology, geospatial technologies, history, international forestry, measurements, policy, recreation, silviculture, social sciences, soils and hydrology, urban and community forestry, utilization and engineering, and wildlife management. The Journal is published bimonthly: January, March, May, July, September, and November.
