Abstract:
Six indexes of tree characteristics of 33 pecan (Carya illinoensis) clones were compared,and the correlation of them,tree classification and landscape application were analyzed.The results showed that there were highly significant differences among ground diameter，breast diameter，tree height,crown height and crown width within a clone or among clones.Clone 14,‘Huangshan No.1’and clone 9 grow fast and could be popularized as excellent clones in the landscape.In the correlation analysis,there were highly significant correlation with the correlation indexes 0.92 and 0.96 between breast diameter and ground diameter,tree height and crown height.Tree form index,closed to the golden section point,was 0.59 to 0.82.The tree was spherical,broad-ovate and beautiful.C.illinoensisshould be a very good species that could be as solitary appreciation tree,courtyard tree,street tree and mixed forest tree in the garden application.
