摘要: [目的] 通过对8种1变种鸢尾属植物的27个形态学特征分析为鸢尾属植物的种间关系提供形态学依据。[方法] 对8种1变种鸢尾属植物的27个形态性编码,以射干为外类群,利用PAUP中的最大简约法进行鸢尾属植物的表型分支分析。[结果] 经简约分析,得到了4棵同等最大简约分支树,其严格一致树显示:①白花马蔺和马蔺聚为一支,其自展值为96%;②四川鸢尾、薄叶鸢尾和锐果鸢尾聚为一支,其自展值为55%,然而,四川鸢尾和薄叶鸢尾与锐果鸢尾的枝分开,其自展值为83%;③蝴蝶花、扁竹兰和扇形鸢尾聚为一支,其自展值为57%。其中,扁竹兰和扇形鸢尾与蝴蝶花的枝分开,其自展值为78%。[结论] ①白花马蔺和马蔺的关系很近,支持将马蔺作为白花马蔺的变种处理;②四川鸢尾和薄叶鸢尾较锐果鸢尾关系近;③扁竹兰和扇形鸢尾两种之间的关系较蝴蝶花更近。

Abstract: [Objective] The aim of the study was to analyzed the 27 morphological characters of 8 species and 1 varietas in Iris and to provide morphological basis for interspecific classification relation-ships of genus Iris. [Method] On the basis of numerical taxonomy study of Iris L. , 27 typical morphologi-cal traits of 8 species and 1 varietas of Iris were coded. The Belamcanda chinensis(L. ) DC was taken as outgroup and their MP phylogenetic tree was constructed. [Results]I. lactea var. chinensis and I. lactea formed A clade and the bootstrap support was 96%. ② I. leptophylla, I. sichuanensis and I. go-niocarpa formed B clade and the bootstrap support was 55%. However, I. leptophylla, I. sichuanensis consisted one little clade from I. goniocarpa and the bootstrap support was 83%. ③ I. japonica, I. wattii and I. confusa comprised the C clade the bootstrap support was 57%. Nevertheless, I. wattii and I. confusa formed one little clade from I. japonica and the bootstrap support was 78%. [Conclusion] ① The relationship of I. lactea var. chinensis and I. lactea was close, supporting the hypotheisis that I. lactea var. chinensis is a variety of I. lactea. ② The relationship between I. leptophylla and I. sichuanensis was closer as compared to I. goniocarpa. ③ I. japonica had relatively distant relationship with I. wattii compared to I. confusa.
