不同榛树叶中过氧化物酶同工酶的研究

Studies on Peroxides Isozyme in Leaves of Different Hazelnut Trees

对6种不同种类榛树叶中过氧化物酶(POD)同工酶测定比较的结果显示:平榛、毛榛及杂交榛共有酶带B4,该酶带可能是榛属的特征性酶带;平榛与毛榛POD酶带表现出明显的差异性,A1、C1和C2 这三条酶带是毛榛特有的,能否作为毛榛的标志带,有待进一步研究;杂交榛酶带特征与母本(平榛)接近;这些实验结果为细胞生物学研究及探讨榛属植物的亲缘关系及种类的区分提供了依据,也为榛树遗传基础的评价和杂交育种提供了参考资料。

To peroxides isozyme analysis in leaves of 6 species hazelnut trees,the results show that existing enzyme belt B 4 in Corylus heterophylla,C.mandshurica and cross hazelnut (Corylus heterophylla♀×C.avellana♂).It is distinguishing mark belt of corylus,peroxides isozyme belt of Corylus heterophylla and C.mandshurica have difference,A 1,B 1and C 2belts are species of C.mandshurica,whether it become distinguishing mark belt .Cross hazelnut characters of enzyme belt as mother(Corylus heterohpylla).This experiment result provides evidence for cell biology to study and affinity relation in plants of Corylus,and references materials for basic valuation of hazelnut trees inheritance and crossbreed.
