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。
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 .
