Modeling genetic effects on growth of diverse provenances and families of loblolly pine across optimum and deficient nutrient regimes

摘要: Optimal deployment of improved loblolly pine (Pinus taeda L.) planting stock in the southeastern United States requires knowing how diverse seed sources and families perform over time across wide range sites used for plantations. This study tests if relative growth performance provenances is same at individual-tree stand levels family block plantings determines what type adjustment may be required to account genetic differences when modeling yield. Ten open-pollinated from two very different provenances, Atlantic Coastal Plain “Lost Pines” Texas, were grown single-family plots test between among under severely deficient optimal nutrition regimes on a nutrient-deficient, dry site. The three-parameter Chapman–Richards function was fit plot means by provenance, family, treatments. Models with provenance- or family-specific parameters C...
