Analyses of Natural Populations of Pecan, Water Hickory, and Their Hybrid, Bitter Pecan

Morphological leaf analyses were effective in studying Carya populations in southern Louisiana. Hybrid indices and scatter diagrams constructed from a composite of leaf and leaflet traits separated the parent species, pecan and water hickory, and characterized the intermediacy of the hybrid, bitter pecan. Water hickory had more individual tree variation than pecan, and it also displayed greater modification due to site differences. The large number of hybrid types encountered on several sites suggests that disturbed bottomland sites may support complex pecan-water hickory-bitter pecan populations.
