摘要: 利用扫描电镜对石竹属(Dianthus)10种植物的种子宏观形态和种皮的微观形态特征进行观察,首次对该属的种皮微观形态特征进行系统报道。研究结果表明:该属的种子宏观形态可分为3种类型:椭圆形、卵圆形和三角形。种皮表面微观形态均为条形—负网状纹饰或负网状纹饰,按网眼形状将其分为了3个类型,种间网眼大小,网脊宽度具明显差异,这对于石竹属的系统分类具有一定的参考价值。

Abstract: The seeds of 10 species of the genus dianthus are observed under scanning electron microscope. The micromorphology of the seed surface is systematically reported for the first time. The results indicate that: the shape of seed can be divided into 3 types: oval, ovate and triangle. The seed coats of 10 wild species are stripes-areolate or areolate. According to the shape of the mesh may be divided into three types. The size of lumina and muri have obvious differences between species. Thus, these are of significant value in the taxon of the genus dianthus.

Key words: Dianthus, seed morphology, seed micromorphology, taxonomy
