The changes in morpho-physiological properties and lipid composition have been studied in the leaves of theplant Plantago media collected from two different places in the Middle Volga region during the summer of 2010. The plants gathered from the first plot (P1 plants) grew on plain ground in the midst of typical meadow-steppe perennial plants. The plants of the second group (P2 plants) grew on a flat slope of the South-West exposition, in the grass community. The leaves of the plants P1 had lower specific area densities but larger areas and masses; they accumulated more levels lipid peroxide products. The changes in lipid compositions depended on the growth phase and habitats. Correlations between morpho-physiological parameters and certain lipids have been established. The amounts of galactolipids (GL) have been shown to correlate with the leaf areas. When the leaf areas were reduced, a ratio between phosphatidylcholines (PC) and phosphatidylethanolamines (PE) decreased. The result of our study showed that gradual changes of morphometrical parameters were accompanied by the alterations in biomass structure and modifications in lipids and fatty acids (FA). © 2016 Elsevier Masson SAS.
