山东蔊菜属种子形态学研究及其系统分类学意义

Studies on the seed morphology of Rorippa in Shandong and its systematic taxonomy significance

对山东菜属植物的种子,从大小、翅、颜色和种子微形态等方面进行了研究;结果表明该属的种子为卵形或近圆形,呈扁平状;种子表面纹饰为网状或乳突状。与近缘属种子形态的研究表明,菜属和豆瓣菜属亲缘关系较近。因种子的形态特点比较稳定,所以菜属的种子特点可以为其分类、生药鉴定以及演化提供种子形态学方面的证据。

The present paper reports the seed morphology of Roroppa in Shandong about its seed size,wing,colour and profound morphology. The seed of Rorippa is ovular or near round,squatshaped. The surface ornament of seed is reticulate or mammilate. By means of relative study,Rorippa is related to Nasturtium. As the morphological features of seed are relatively stable,therefore,the seed of Rorippa may provide seed morphological evidence for its taxonomy,dried medicinal herbs appraisal and evolution.
