| 摘 要： | 本文对中国滨藜属(Atriplex L.)13种植物的种子形态进行了观察并探讨其在分类学中的意义. 在种子外部形态观察基础上明确了胚根位置类型的划分标准, 认为滨藜属胚根位置仅有胚根上位和胚根侧位两种类型;利用扫描电镜首次观察报道了该属种皮微形态特征。研究结果表明, 种子形态及种皮微形态特征对属内类群划分具有较大的分类学意义。

| Abstract: | In the present paper the seed morphology of 13 species of Atriplex L. from China were examined.Radicle superior and lateral were defined in this genus by our standards. The micromorphology of seed coat of the genus was reported here for the first time. The seed coat sculpture of these species can be divided into eight types: (1) Smooth (2)Rugulate (3)Ripple (4)Cerebelloid (5)Ravine (6)Bubble,(7) Reticulate (8) Striate. There is the second reticulate or striate ornamentation or not. The results show that the morphological features of seed, such as shape,colour. radicle orientation and the micromorphological features of the seed coat,can supply characteristic significance to the taxonomy of the genus. |
