The changes in morpho-physiological properties and lipid composition have been studied in the leaves of the plant Plantagomedia collected from two different places in the Middle Volga region during the summer 2011. The plants gathered from the first plot (P1 plants) grew on plane 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 Р 1 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 have been shown to correlate with the leaf areas. When the leaf areas were reduced, a ratio between phosphatidylcholine and phosphatidylethanolamine 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 FA.
