摘 要 ：本文用相容性分析方法(Compatability snalysis)分析了真正柑桔果树群(芸香科Rutaceae-柑桔亚科Aurantioideae-柑桔族(Citreae)-柑桔亚族(Citrinae)植物内各属间的分支学关系。给出了建立在7个相容性性状组成的最大族所决定的分支图。性状极性的确定使用了外群法。结果表明,柑桔属(Citrus L.)和多蕊桔属(Clymenia Swing)构成一个单系类群,他们的姐妹群是金柑属(Fortunella Swing.)。被认为起源于中国的3个属,柑桔属(Citrus)、金柑属(Fortunella)和积属(Poncirus Raf.)并未构成一个单系类群。本文还利用分支关系分析和讨论了真正柑桔果树群的种系发生关系。

Abstract:Cladistic relationship of the true fruit trees(Citreae, Rutaceae) is studied by character compatibility analysis. The cladogram based on primary clique of 7 morphological characters is presented. According to the cladogram, Citrus L. and Clymenia Swingl. form a monophyletic groups, whose sister group has Fortunella Swingl. Citrus L., Poncirus Raf., and Fortunella Swingl., which has been regarded as originating in China, do not form a monophyletic group. The phylogenetic relationship of the true citrus trees is analysed and discussed.
