Seed Morphology and Its Taxonomic Significance of Spiraea L. in China

  • 摘要: 利用光学显微镜和扫描电镜对中国25种4变种绣线菊属(Spiraea L.)植物的种子形态特征进行了研究。结果显示,绣线菊属植物种子外观上呈窄线形至椭圆形,表面有光泽和条纹,种子颜色为红棕色至深褐色;种皮纹饰可分为网纹、复网纹、负网纹和链状网纹4种类型。种子按长宽比的划分方法在一定程度上支持该属传统的组下系的划分;种皮纹饰在种间具有明显的差异,可作为中国绣线菊属植物种的分类依据。本研究为绣线菊属的分类及系统学研究提供了种子形态及种皮微观形态方面的新资料,对进一步完善该属属下分类具有借鉴意义。
    Abstract: The seed morphology of 29 taxa (including 25 species and 4 varieties) from Spiraea L. in China was studied using light microscopy (LM) and scanning electron microscopy (SEM). Results showed that seeds of Spiraea were narrowly linear to elliptic in shape, with testa lustrous and striate, reddish brown to dark brown in color. Ornamentation of seed coat was ascribed into four types, reticulate, double reticulate, areolate and chainlike reticulate. The ratio of seed length to width (L/W) supported the traditional division of the subgroups in this genus. Seed surface sculpture may have definite systematic importance in the taxonomy of Spiraea species.
