The variability of morphological characteristics of plants allowed to study their adaptations to environmental. We investigated 37 populations of Phleum pratense in different conditions of the flood grasslands of the Luga river. For analyse of the data base (1110 records and 23 fields) we used multivariate statistical methods (ANOVA and PCA). The variability of morphological characteristics was connected with 4 factors: F1- the form and size of a inflorescens, F2 - the form and size a leaf, F3 - the size of a culm, F4 - the number a merithallus. They had 78,6% variance of all the variability of the morphological characteristics. The biggest size of the culm, the leaf and the inflorescens was observed in the sites of the mesophyte flood grasslands of the Luga river. These sites are the most favourable habitats for Phleum pratense.
