| 摘 要： | 从生态学角度对三江平原芦苇的营养器官进行了解剖学研究。芦苇的不定根、根状茎、茎和叶的解剖结构表现出了对水生和湿生环境的适应性。不定根的外皮层产生一层纤维细胞层，具发达的通气组织；根状茎中维管束散生。呈三环分布在基本组织中，薄壁组织细胞贮存有淀粉粒；根状茎和茎中均具发达的髓腔和通气组织；叶为等面型叶，机械组织发达。 |

| Abstract: | The anatomical structure of vegetative organs of Phragmites australiswere studied from ecological perspective. Its structure of adventitious root, rhizome, stem and leaf was adaptive to the wetland habitat.The outer cortex of adventitious root had a layer of fiber cell and advanced aerenchyma. The vascular bundle of rhizome was diffused and distributed in three circles in parenchyma. The parenchyma cell stored starch grains. Both rhizome and stem had advanced pith cavity and aerated tissue. The leaf type was isolateral and had many fiber cells. |
