摘要
对三江平原三种不同生境(典型草甸、沼泽化草甸、沼泽)下生长的小叶章根的解剖结构进行的研究表明:三种不同生境条件下小叶章根的结构组成基本相同,都由表皮、皮层、维管柱构成,未见其它特殊结构。但各结构参数在数量、大小等方面均呈现出显著差异,表明小叶章根的结构对环境变化具有一定的适应性。
The anatomy structure of root of Deyeuxia angustifolia from three different environment in Sanjiang Plain was observed.The results showed that: under different environment,the component of anatomy structure of root are basically same.They are all made up of epidermis,cortex,vascular cylinder,without any variant structure.But the amount and size of each parameter showed significant difference,Which showed that the root of Deyeuxia angustifolia has adaptive abilities in different environments.
