摘要：

用丙烯酰胺凝胶电泳分离了胡桃属Juglans L．10种植物80份材料的过氧化物同工

酶，共出现16种酶谱。种内酶谱多态，但酶带间的差异小于种间酶带差异。用“酶谱距离”

及特异酶带可将10个种分成4组，与胡桃属分类基本吻合。黑核桃组的酶带最多。胡桃楸

次之，核桃及灰核桃最少。根据同工酶的产生与进化的关系，可认为黑核桃与胡桃楸比核桃、

灰核桃进化。胡桃属内平均“酶谱距离”为0.52，推测该属应发生在晚白垩纪到古新世。

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.

Key words: Juglans, Lsozyme
