摘要/Abstract

摘要： 运用细胞离析法观察表明，燕麦叶鞘及穗下节间、穗轴、颖壳和芒的同化细胞形态均与叶肉细胞类似，而且随叶位升高，叶鞘同化细胞形态逐渐复杂化的趋势也与叶肉细胞类似。与叶片一样，上述绿色器官也均具有同化CO2，进行光合作用的能力。

关键词: 燕麦（Avena spp.），叶鞘，绿色器官，细胞形态，光合作用

Abstract: By means of cell separation technique, morphology of assimilating cells of the green organs besides leaf blades were investigated. The results showed that the assimilating cells of leaf sheaths, internodes beneath the ear, ear aces, awns and glumes were similar to the mesophyll cells of leaf blades

Key words: Oats (Avena spp.), Leaf sheath, Green organs, Cell morphology, Photosynthesis
