葛仙米表层结构的扫描电子显微镜观察

目的]探寻观察葛仙米表层结构的新方法。方法]利用扫描电镜技术，对野生葛仙米与室内培育葛仙米表皮超微结构进行观察。结果]野生与室内培育葛仙米表皮都呈网状交错排列的纤丝胶质混合结构特征，不同的是室内规模培育葛仙米群体表皮外层有藻丝分布，而野生葛仙米表皮外层未见藻丝分布。10μm以下的葛仙米群体表皮质感厚实，呈现出很多皱纹，扭曲。结论]扫描电子显微镜技术是研究葛仙米群体发育的有效工具，值得推广。

Obsevation for Surface Structure of Nostoc sphaeroides Kutzing under Scanning Electron Microscope

Objective]The experiment aimed to explore a new way for observing surface structure of Nostoc sphaeroides Kutzing.Method] The scanning electron microscope was used to observe the epidermal ultrastructure of wild and cultured Nostoc sphaeroides Kutzing.Result] The epidermis of wild and cultured Nostoc sphaeroides Kutzing showed mixture structure of fibril colloid which was reticular arranged.The difference between wild and cultured Nostoc sphaeroides Kutzing was that the outer epidermis of cultured Nostoc...
