葱属隶属地位的探讨

DISCUSSING SYSTEMATIC POSITION OF GENUS ALLIUM

探讨了葱属的隶属地位 .从形态特征、花粉特点和化学成分等方面对葱属及其相近属 (石蒜属Lycoris,知母属Anemarrhena ,百合属Lilium )分别进行了分析 ,最后选取 2 3个性状 ,应用分支分类中的最大同步法对其进行处理 .结果表明 ,葱属和其它各属区别较大 ,不适于划归同一科 ,应另立葱科 ,将葱属隶属于其下 .

In order to discuss systematic position of genus Allium ,the author selects 23 classification characters on morphological,pollens and chemicalof genus Allium and its relative genera ( Lycoris,Anemarrhena and Lilium ),uses method of maximal same step length to get a cladogram.The cladogram shows genus Allium distinguishes with the other three genus.It is no reason to put it and any of the other three genera in the same family.So,it is necessary to creat a family Alliaceae and have genus Allium belong to it.
