摘要: 借助于扫描电子显微镜,对我国东北地区槭属(Acer)的11种1变种的种皮雕纹进行了扫描观察,并拍制了电镜照片。从种皮的雕纹类型看,槭树属的种皮可以概括为四种类型:(1)嵌合型; (2)穴状条纹型; (3)条纹型; (4)网格型。雕纹的形态也支持了色木槭和元宝槭作为两个独立种的处理意见,以及小果紫花槭作为紫花槭(Acer pseudo-sieboldianum (Pax.) Kom.)的种下等级即变种(var.koreanum Nakai)的处理意见。

Abstract: The testa sculptures of 11 species and 1 variety belong to Acer Linn.in the Northeast of China were examined by the help of scanning electron microscope (SEM) and the pictures of SEM were taken.The testa sculptures of Acer are divided into four types, as follows:(1) moasaic; (2) hole; (3) striate; (4) reticulate.The close interrelation between similar species is analysed in order to prove reliable evidence for taxonomy of Acer Linn.The morphology of sculptures also support the view of that Acer mono and Acer truncatum were regarded as independent species respectively and it does the view of that Acer pseudo-sieboldianum var.koreanum was regarded as variety of Acer pseudo-sieboldianum.

Key words: Acer, Seed sculpture, Taxonomic significance
