Ecological analysis of morphological and genetic variation revealed that:(1) The averages of morphological characters were significantly negatively correlated with WSF (2) Dominant frequencies of some RAPD loci were significantly correlated with WSF (3) The correlation between morphological variation and genetic variation was not significant (4) The cluster analysis based on morphological and genetic evidence supported that all population can be divided into three ecotypes: saltmarsh reed, freshwater reed and giant reed.
相关分析表明:种群内各形态特征的平均值均与水盐联合影响因子显著负相关,但种群内形态变异系数与水盐联合影响因子普遍相关不显著;种群遗传多样性指数与水盐联合影响因子相关不显著,但部分生境倾向型的RAPD位点的显性频率和来自等位酶分析的克隆多样性水平与水盐联合影响因子显著相关;形态变异系数与遗传多样性指数相关不显著,但相关系数均为正值。

The basal diameter, height of aerial stem, leaf length at middle stem, leaf width at middle stem, internode length at middle stem, internodes number and panicle length of 30 plants from every population were recorded. The statistics of morphological characters showed that the distribution trends of the averages of morphological characters are similar among populations. However, the coefficients of variation within population of 7 morphological characters were very different. The CV of internodes was largest and the CV of height was smallest within population. F-statistics showed that the differences of all morphological characters among populations were significant (P.01). But the differences among populations were different between different groups. The cluster analysis proved that all populations could be divided into three types: salty reed, freshwater reed and giant reed.
对来自每个种群的30个个体的基径、株高、中部叶长、中部叶宽、中部节间长、节间数、穗长7个形态特征的统计分析表明:各形态特征平均值在种群间的分布趋势相似,但变化幅度不同,株高、叶长等营养特征变化较大大,生殖特征穗长的变化较小;7个形态指标在种群内的平均变异度从大到小依次为中部节间长、中部叶宽、穗长、中部叶长、基径、节间数、株高,种群内的平均形态变异度与生境异质性有关;7个形态指标在种群间均差异显著,但多重比较分析显示显著差异主要存在于BZH、淡水生境种群和盐渍化生境种群之间,在相似生境种群间的形态差异不显著;以形态特征为依据的聚类分析支持将15个种群分为三类:盐生芦苇、淡水芦苇和巨型芦苇。
