| 摘 要： | 采用石蜡切片法观察了塔里木盆地的碱蓬属6种植物的解剖结构,表明碱蓬属6种植物具不同的适应盐生生境的结构特征:(1)星花碱蓬、平卧碱蓬与肥叶碱蓬表皮细胞外侧壁常外凸生长,五蕊碱蓬、硬枝碱蓬与高碱蓬外凸生长不明显;(2)碱蓬属6种植物叶肉为环栅型,特别的是平卧碱蓬、肥叶碱蓬与五蕊碱蓬表皮下分化出了一层不含或含极少叶绿肥体的贮藏组织;(3)硬枝碱蓬栅栏组织细胞的形态小、细胞的层数较多,而肥叶碱蓬叶肉栅栏不发达,分化出了大量的贮藏组织;(4)硬枝碱蓬与高碱蓬的主脉维管束内分化出了1层形成层而另外4种没有形成层.

| Abstract: | We used olefin section to study anatomy of the leaves from 6 types of Suaeda from Tarim Basin of Xinjiang,it showed that there were different adaptive structures in the trees for salty environment where these leaves of the trees lived:(1) Three species of Suaeda,Suaeda stellatiflora,S.prostrata and S.kosinskyi having extruding growth of outer flank on epidermic cells,while that of it in S.arcuata,Suaeda rigida and S.altissima were not significantly extruding;(2) The mesophyll in the leaves of 6 species of t... |
