摘要: 本文报道了风毛菊属28种植物瘦果表皮纹饰的扫描电镜观察。结果表明风毛菊属果皮纹饰有四种类型:即条纹型(有隔条纹亚型和无隔条纹亚型)、孔纹型、网纹型、复合型。果皮纹饰显示出明显的差异性,可作为划分组成或亚属的标准,与传统分类结果基本一致。也可为某些种间界限不清的种类提供有用的证据,但对于大多数种类来说,果皮纹饰在种的划分上还有待进一步研究。

Abstract: The micromorphological features of achenes surfaces of 28 species in Saussurea were studied. The result has showed that the achenes of Saussurea edsbit a complex and high micromorphological diversity. The surface features under SEM may be divided into four types:foveolate, reticulate, striate, compound. Based on the comparing of different species. the authors considered that the micromorphologic al features of achenes provide most valuable criteria for classification between sections level, but at species level their significance need more studying.
