摘要
新疆委陵菜属植物的花粉粒在光镜和低倍(2500以下)扫描电镜下几乎没有区别,均为辐射为称花粉,长球形或卵球形,三孔沟,表面条状纹饰,在高倍扫描电镜下(8000—20000),花粉在孔沟形状、条脊的类型、宽度、脊间物征及密集程度存在着一定差异,据此将其分为四种类型:木本型(Dasiphoratype),草本Ⅰ型(HerbaceustypeⅠ),草本Ⅱ型(HerbaceustypeⅡ)、草本Ⅲ(HerbaceustypeⅢ),这些对该属植物的分类和演化有重要意义.
In this paper, the pollen of palvnology of this genus is almost same of the optical microscope and theelectron microscope (2500), radiation symmetry long-globe oregg-shaped, 3 hole-channel, stripe. But differsin the shape of hole-channel, type of stripe, etc. on the electron microscope (8000-20000). In this paper,Pollens are classified to 4 typies: Dasiphora type. Herbacepe 1. Herbaceustype Ⅱ, Herbaceus typeⅢ
