摘　　要：对扎龙湿地5个芦苇居群的基径、株高、叶长、叶宽、节间数、穗长6个性状进行了比较分析.结果表明,芦苇各形态特征在居群间的差异显著,变异系数由大到小的排列顺序为:基径>穗长>叶长>节间数>叶宽>株高;居群间的变异程度由大到小的排列顺序为局址(J)>赵凯(Z)>唐土岗(T)>满代(M)>克钦湖(K);各形态指标间除节间数外显著相互关联.Phenotypic diversity of five populations of Phragmites australis in Zhalong wetlands were analyzed by six phenotypic traits, The results showed that six phenotypic traits of five populations varied obviously. The coefficient of variation descending order, the basal diameter〉panicle length〉leaf length〉internode number〉leaf width〉plant height. The descending order of variability among populations was JZ, ZK, TrG, MD, KQH. The leaf length, leaf width, plant height and internode number were the main traits involved in the phenotypes differences of Phragmites australis. Except internode number morphological index significantly interrelated.
