摘要: 中国新疆龙胆科5属18种种皮的扫描电镜观察展示了种皮微形态的高度多样性,这5个属可以分为二大类型,第一类包括龙胆属、扁蕾属和獐牙菜属,它们的种皮均具雕纹,此类型又可以分为3小类,每小类对应一个属,这3个属的雕纹类型互不相同;第二类包括假龙胆属和花锚属,它们的种皮均光滑。

Abstract: Scanning electron microscopy of the seed coats of 18 species from 5 genera of Gentianaceae from mountainous regions of Xinjiang, North-Western China, reveals a high diversity of seed micromorphology. Two main types can be distinguished. The first comprises Gentiana, Gentianopsis and Swertia with sculptured seed coats. It may further be divided into three sub-types, each of which corresponds to a genus. The second type is characterized by smooth seed coats and is observed in Gentianella and Halenia.
