摘要: 利用光学显微技术对生长在内蒙古赤峰盐碱地上马齿苋(Portulaca oleracea)的营养器官进行了形态解剖学研究,并用黑土地上生长的马齿苋作了对照。结果表明,不同生态环境中生长的马齿苋解剖结构显著不同,盐生马齿苋具有适应盐渍环境的结构特征,这些特征表现为:营养器官通气组织发达;根的次生结构中木栓发达;根、茎的薄壁组织中含有大量的黏液细胞和糊粉粒;叶片表皮的角质膜厚;叶肉中含晶细胞、叶绿体及贮水组织丰富;而这些特征是黑土地上生长的马齿苋所不具备的。

Abstract: This paper deals with anatomical structures of the vegetative organs of Portula oleracea growing in saline-alkali soil of Chifeng, contrasted to the same species living in black soil, using light microscopical technique.The results showed that it adapted to saltmorphic circumstances through the following characters: A lot of aerenchyma existed in the vegetative organs;Phellem highly expanded in roots;thick cuticula;more mucilage cells and aleurone grains in parenchyma of roots and stems;A lot of water storing tissue.rich crystal cells and chloroplasts existed in mesopyll tisses.such characters were not existed in Portulaca oleracea which lives in black soil.

Key words: salinized soil Portulacea oleracea, saline morphic structure, ecological adapt
