Genotype by Environment Interaction Under Optimal and Deficient Nutrient Regimes in Loblolly Pine at Age 12

Year 12 growth data from the SETRES-2 study site were analyzed for growth differences due to nutrition, provenance, and family effects. Established in the winter of 1993-94, SETRES-2 is a loblolly pine (Pinus taeda L.) genotype by environment interaction study located in the Sandhills of Scotland County, NC. The study is a split-split plot experimental design, with 178 nutrition (annual optimum fertilization and non-fertilized) main plots, provenance (Atlantic Coastal Plain and “Lost Pines” Texas seed sources) sub-plots, and family (five OP genetic families per provenance) sub-sub-plots nested in provenance.
