[Allozyme variability of provenance populations of Robinia pseudoacacia from Middle Europe].

Using starch gel and polyacrylamide gel electrophoresis, 11 enzyme systems of two-year-old seedlings from 18 provences of Robinia pseudoacacia distributing in the middle Europe and America were investigated. There were 14 polymorphic loci with a proportion of 70.0% in twenty loci.
