The Reliability of Selected Morphological Characteristics in Identifying Carya x lecontei Through Controlled-Pollination Experiments
Abstract:Controlled pollinations were performed among pecan [Carya illinoensis (Wangenh.) K. Koch], water hickory [Carya aquatica (Michx. f.) Nutt.], and their natural hybrid Carya x lecontei Little. The F2 hybrids exhibited larger nut weights than pecan but not water hickory. After one growing season the hybrid seedlings were larger in height and diameter than those of pecan, but smaller than the water hickory seedlings. The F1 hybrid means were greater than pecan for average serration number, leaflet number, and rachis length. The values were generally less than those obtained for water hickory but the differences were not significant. Stomatal index was not useful in separating among taxa. A discriminant analysis based on leaf characteristics indicated that it was possible to distinguish between pecan, water hickory and the F2 hybrid. However, it was not possible to distinguish the F1 hybrid or backcrosses from the parental species. Forest Sci. 30:475-483.
