Abstract:
Isozymes of peroxidase of 10 species in Juglans L. were analyzed by using poly-
crylamide gel electrophoresis, and, as a result, 16 different patterns of isozymes were observed.
Polymophism of isozymes patterns appears within species and more significant differences in pat-
tern between species have been found. “Zymogram distance” was measured for each species
pair and section pair. The ten species may be divided into 4 groups according to their “zymo-
gram distance” and specific bands, which accords with the classical taxonomy of Juglans L..
Evolutionary relationship among species and rate of evolution for Juglans L. are discussed.
