Pecan [Carya illinoensis (Wangenh.) K. Koch] is a North American deciduous tree (Fig. 1), and belongs to the Juglandaceae family, which includes hickories, walnuts, and the genus Carya, which has about 25 species of large trees. In its native range the tree reaches a maximum height of 55 m (180 feet) and 210 cm (83 inches) in diameter (Peterson 1990), being the largest of the native hickories. Leaves are alternate and odd pinnate, with 9 to 17 lanceolate leaflets (Reed and Davidson 1954). Among genotypes, the leaflet number ranges from about 9 to 17; leaflet length is commonly 5–10 cm. Leaf color varies from a light or yellowish green to an extremely dark green (Sparks 1992).
