【摘要】 用聚丙烯酰胺凝胶垂直板电泳测定了金柑属（Fortunella）、枳属（Pon-cirus）和柑桔属（Citrus）30个分类群花瓣的过氧化物酶同工酶。根据谱带的异同,分析了彼此之间的亲缘关系。结果表明,以上三属分别具特有的谱带;柑桔属中典型的基本种枸橼（C.medica）、柚（C.grandis）、宜昌橙（C.icha-ngensis）谱区狭小,集中在P_x20以前;四季桔（C.madurensis）可能是罗纹（Fortunella japonica）与柑桔属植物的属间杂种;枸橼柠檬类可分为亲缘关系密切的三个组群。过氧化物酶同工酶可用来鉴别某些品种、品系。此外,宽皮柑桔酶谱类型复杂,有待进一步研究分析。更多还原

【Abstract】 Isoperoxidase of the petals of 30 taxa of Fortunelia, Poncirus and Citrus was determined by polyacrylamide gel vertical slab electrophore-sis. The affinity relationships between the three genera are discussed based on the results of analysis of the zymoram. The results are briefly summarized as follows : Each of the three genera has its own specific band pattern respectively. The zymogram zones of Citron ( Citrus medi-ca ) , Pummelo ( C. grandis ) and Ichang papeda ( C. ichangensis ) , are lo-cated in the narrow area between Px1 to Px20. The Calamondin ( C. ma-durensis ) may be intergeneric hybrid between Luo-wen ( Fortunelia japoni-ca ) and Citrus. Citron-lemon group can be divided into three sub-groups which have close-relationships according to the analyses of zymogram. The isoperoxidase can be used to identify Species, varieties and clones in some of above mentioned taxa. However, the zymograms of manda-rins are quite complex and should be studied further.更多还原
