Abstract

Provenance plantings on favorable sites within the natural range of slash pine show little genetic variation in survival, growth, and resistance to the southern fusiform rust. North or west of the species' range, however, or on droughty sites anywhere, trees of northern or western provenance generally survive best. Almost all of the slash pine plantings established before 1940 and many even later were determined to be from seed collected in northeastern Florida and south Georgia.
