摘要：

Honey locust has high genetic diversity within populations (HE = 0.198), and low, but significant genetic differentiation among populations (GST = 0.059). Even small amounts of clonal growth can cause large increases in the amount of substructuring in populations. Spatial genetic substructuring among juveniles at 2 E Kansas sites most likely represent the presence of family groups. The overall level of spatial genetic substructuring at both sites was somewhat greater in the juvenile classes than in the nonclonal adult classes. Limited gene movement may cause a steady increase in spatial structure from generation to generation. -from Authors
