摘要
用递真空扫描电镜技术和能量分散型X射线 (EDX)分析方法研究了 12种多年生牧草叶表面的微细构造。结果表明 ,每种草叶的正面和背面都有各自独特的微细构造 ,草种间差异明显 ;将扫描电镜图片贮存在高密度光盘内 ,建立各草种叶表面的微细特征图像库 ,对生育初期牧草种的识别及其分类极为有用 ;蒙古冰草叶背面的白色乳突状结构、新麦草叶正面的白色砖块状结构及其叶背面的白色披针状结构都是由硅质成分积累而成的特殊构造。
The leaf epidermal microstructure among 12 perennial grasses was studied by using scanning microscope and Energy Dispersive X-ray (EDX) microanalysis. The results showed that the adaxial and abaxial epidermis of each grass had its unique microstructure, and there were significant differences among the 12 perennial grasses; the scanning photoes were storaged in photo CD with high density to construct the photo pool of leaf epidermal micro-characteristics, which was very useful to identify and classify grasses in early growth stage. The white mastoid structure of abaxial leaf epidermis of Agropyron mongolium, and white brick-shaped structure of adaxial leaf epidermis and white lanceolate structure of abaxial leaf epidermis of Psathyrostachys juncea through EDX analysis were consisted of Si element.
