三角仪

The distribution of Na(superscript +) in intracellular and extracellular spaces in leaves of arrowleaf saltbush subjected to salt stresses was investigated by using a scanning electron microscope facilitated with an Auger electron spectrometer. The role of salt bladders in salt resistance of A. triangularis was analysed in terms of salt accumulation and secretion.

用扫描电镜和能谱仪测定不同浓度NaCl胁迫2 wk后的三角滨藜幼叶和成熟叶中Na在细胞外和细胞内的分布情况，并利用原子吸收分光光度计测定叶片中Na的积累量，同时还观测了盐囊泡及其与盐的积累、分泌之间的关系。
