豆科黄华属植物种子表面特征的研究

在扫描电镜下观察了豆科黄华属Thermopsis 18种植物种子的表面纹饰，发现 T．alpina，T.bar- bata，T．inflata，T．lupinoides，T. licentiana，T.smithiana和T．turkestanica的种子表面为粗网状，T californica，T.divaricarpa，T. macrophylla，T．mollis的种子表面为细网状，T.gracilis，T.montana，T. fabacea的种子表面为相对平滑型纹饰，T．alterniflora的种子表面为不规则条形，T．chinensis的种子表 面为粘膜状，T.rhombifolia的种子表面为条形及 T．viuosa的种子表面为碎屑状纹饰。结果表明黄华属的种子表面特征对属下类群的划分有一定意义，对澄清某些混乱的种有一定价值。

Surface features of seeds in Thermopsis (Leguminosae)

In this paper, surface features of seeds in 18 species in the genus Thermopsis R. Br. (Leguminosae) were observed under scanning electron microscope (SEM). Their seed surface was found to be quite well differentiated and to have important taxonomic value. T. alpina, T. barbata, T. inflata, T. lupinoides, T. licentiana, T. smithiana, T. turkestanica had reticulate seed surface; T. californica, T. divaricarpa, T. macrophylla, T. mollis had finely reticulate seed surface; T. gracilis, T. montana, T. fabacea had relatively smooth seed surface; T. alterniflora had irregularly striate seed surface; T. chinensis had mucilaginous seed surface; T. rhombifolia had striate seed surface, and T. villosa had fragmented sculptures on seed surface. Some taxonomically disputable species in Thermopsis can be distinguished by the surface features of seeds.
