Differences between 13 common reed (Phragmites australis) populations, growing in urban conditions within the town of Poznań (western Poland), are described by 8 morphological traits of panicles' variability and the frequency of peroxidase (dimeric and monomeric) allozymes. Values of morphological characters were processed statistically using agglomerative clustering by the closest neighbours (UPGMA) method based on Euclidean distances. Proteins were separated in the starch gel electrophoretic procedure, showing cathodic migration. Populations are polymorphic and have a certain level of heterozygosity. The level of populations' diversity (DST = 0.097) is lower than the intra-population variability (GST = 0.187). The gene flow between populations is rather low (Nm = 1.090).

Using a transect technique, each of 12 reed Phragmites australis (Cav.) Trin ex Steud. populations collected in middle part of Odra River-basin, represented by more than 30 plants, were compared with 3 populations from other part of the country and 1 from France. Each panicle was examined according to 15 morphological traits. Results of measurements were subjected to multivariate analysis of variance, to analysis of canonical variables and used for construction of a minimum spanning tree (= dendrite) on the basis of the shortest Mahalanobis distances. The obtained results indicate that populations are generally similar. One population from France (Orleans) shows visible separateness. It may suggest that morphological traits of panicles may be useful in investigations of the reed P. australis populations of a larger geographical distribution.
