Geographic Variation in Survival, Growth, and Fusiform-Rust Infection of Planted Loblolly Pine

Abstract

Abstract Loblolly pines from 15 geographic seed sources, grown in 13 widely separated areas in the southern United States, displayed well-defined patterns of variation after the first 10 years. In practically all plantings trees of western origin had survived best. In all but the coldest locations trees from coastal areas had grown fastest. Trees from western sources and from the one source farthest to the northeast were consistently least infected by fusiform rust.
